How to make your Apple Photos library smaller. Use H265 (HEVC) for your videos.

After many trips and vacations, my Apple Photos library was more than 500 gigabytes big. What can I do to make my library smaller? I start to use H265 (HEVC) for my videos.

My big Apple Photos Library

Apple Photos is my main media storage application where I store all my videos and photos. All my media is synced to the Apple cloud with iCloud. If I make a picture with my iPhone it will automatically appear on my MacBook Pro. But it also happens vice versa. If I import the photo’s and videos from my DSLR and pocket camera on my Macbook those files will also appear on my iPhone. If I delete a file on one machine, its also automatic delete from the other machine. Also, the trash is synced on my devices. If I delete a picture on my MacBook I can use my iPhone to recover that picture. Even the edits I make are synchronized. Those are features of iCloud I really appreciate.

Slowly my Apple Photos library is growing bigger and bigger. You go on a trip and shoot a lot of videos. You found an old folder filled with old vacation photos and videos on an external drive. Your parents send you old pictures they scanned. All those media files I collect in Apple Photos. Before you know the library is around 550 gigabytes big. The library contains 38 years of my life in digital form.

A couple of months ago I decided that its time to take control of my media collection. I did every day a Pomodoro. This is a productivity trick that you focus 25 minutes on one task. For every day I focus 25 minutes on my library. I started to delete pictures that had no meaning anymore. When I just got my DLSR I made without a problem 600 pictures at a party. As a reminder, I only kept 10 pictures of that party. I used my phones as a memory. In a couple of weeks, I managed to delete 15.000 pictures.  I’m still not at the end of the library. Every day I do a small chunk of work. But still, my library is big. I found out that in this 550GB big library around 400GB is video. That’s a lot.


In the autumn of 2017, Apple released their new operating systems. OSX 10.13 for the Apple computers and IOS 11 for the mobile devices. In this software, Apple introduced a new codec for video and photos. Let’s talk about this new codec for video. HEVC. What stands for High-Efficiency-Video-Coding. Its a way better compression for storing video. Apple claims that it can make your video twice as small as the previous video codec they used: H264. I can tell you this is true. But videos I shot with my Canon, Sony and SJCAM camera’s even become smaller.

I made a short youtube video to show the difference in quality between H264 and HEVC. You see the change in quality is negligible. But the saving in disk space is huge!!!

The original video is a 34 seconds long and is 224MB big. Its recorded with a 50Mbit bitrate on a Sony Cybershot RX100 mark 3 camera. After I encoded the video to HEVC it’s only 17MB big. That’s only 7,5 percent of the original.  You will lose some color and sharpness. But for private videos, I don’t have a problem to encode it to HEVC.

I started to encode all my old videos in HEVC format. In the table, you can see some examples of video clips I encoded.

Sony Cybershot RX100 Mark 337 seconds242.8 MB20 MB8.2 percent

Why would I want to make my videos smaller? It will take less space at my harddisk. I need less space in the iCloud. The video will load faster if I want to stream it to my iPhone. Because my Apple Photo Library is getting smaller I have more space for other files on my hard disk.

Using Permute to encode the videos

When I wrote this blog post there are two good video encoders for making HEVC files for OSX. Handbrake and Permute. Handbrake is free, faster and offers way more settings than Permute. But I choose to use Permute because of a better workflow. Plus Permute conserve the metadata of the video file. I can tell you that this is super important. Apple Photos is using the date and time metadata in the video for the correct place in the timeline. If your video is shot on 04 January 2013. And you encode it with Handbrake at 08 August 2018. Than Apple Photos will not place that video in the timeline on 04 January 2013 but on 08 August 2018. So your timeline will be messed up. Permute keeps the correct recording date in the encoded video file. Using Permute is too simple to fail. With Handbrake, you can make easy a mistake. There are just too many settings in that program. Permute cost only 10 dollars. But you can also find it in the Setapp subscription.

How did I configured Permute?

I made a custom preset for my encoding work. I want to keep the same video and audio quality as the source video. If a video is 4K it will be downscaled to 1080P.

I have a folder on my desktop with the name “IMPORT APPLE PHOTOS” where Permute automatically saves the encoded videos. I put CPU usage on low so I can use my computer when Permute is busy. Disable previews is also a good advice. Otherwise, Permute can spend minutes on making small previews of the videos. For me, that’s not important. It only cost a lot of time.

This is important. You need to tell Permute that you want to preserve the creation date of your video. Otherwise, the encoded video file will get the date of the day you encoded it. If you import the video back to Apple Photos it will have the wrong place in the timeline. So turn it on.

My workflow

In Apple Photos I made an album with the name “To Permute”. When I’m doing my Pomodoro and I find a video which I want to encode to HEVC I just drag that video to the “To Permute album. Before I will sleep or I don’t want to use the computer for a long time  I will select all the videos files in the “To Permute” album and do right-click on the files. I choose then edit with Permute.

Apple Photos will prepare all the selected videos and send them to Permute. Check in the left-top bar if you choose the correct preset.  The only thing you then need to do is press the start button. Now you need to wait. Some videos are encoded in a couple of minutes. But I also had some long videos that took two days. My MacBook is not that fast. Read my blogpost about keeping a MacBook cool.

When Permute is done with encoding I just drag all the video files in the “IMPORT APPLE PHOTOS” to Apple Photos. Do a quick check if the videos are oke. After that, I just delete the videos in the “To Permute” album.  When I do my next Pomodoro I just start over with a new batch of videos.

In the near future, I want to use an Apple Script that will import the videos automatically after Permute encoded it. I found this thread at the Apple forum how to do that.

Three weeks later

In three weeks time, my Apple Photo library shrunk from 550 GB to 300 GB.  It’s still a work in progress. I hope to get my library under 200 GB. I also hope to find an easy workflow to convert some raw photo’s to JPG format, or even to HEIC photo format. I will share this on my blog if I find a good method.

Happy encoding.

Thermal design in the Apple MacBook Pro is a disaster?

This blog post describes my steps to make my old Apple MacBook Pro run cooler in a warm climate under constant processor load.

When my Macbook turns older. Its somehow starts to feel slower. It’s weird because its still the same computer I bought four years ago. With every OSX version that Apple releases it makes my computer feels faster and it makes it feel slower. I have to explain this. My computer feels faster after the release of METAL for handling the graphics parts. But its feels slower of all the new software features that are integrated into every new OSX release. I also have that gut feeling that Apple isn’t giving OSX any priority anymore. The big money is made with the IOS devices. Why spent a lot of resources on OSX? Most things that are now coming to OSX and the Apple computers are innovations that are first made for the IOS devices. IOS get the optimization and new features first, OSX gets it later.

My late 2013 MacBook Pro 13 inch has an Intel 2.4Ghz I5 mobile processor with a TDP of 28 watts. This means that the processor can produce up to 28 watts of heat energy. The i5-4258U processor is a combined CPU and a GPU in one packaging. So the CPU and the GPU share the same footprint and share the same heat pipe that transports the heat from the processor to the heatsink. The fan is blowing this thermal energy out of the enclosure.

The i5-4258U has the base frequency of 2.4 GHz. But can use the Intel® Turbo Boost Technology to push the frequency up to 2.9 GHz if there is enough cooling. Lately, I’m using the Macbook day and night for the encoding of videos. So the processor is pushed to the limit. Because its here around 30 degrees Celsius the Macbook could not reach the full 2.9 GHz. It was hopping between 2.4 GHz and 2.7 GHz.  There has to be a way to improve this.

Every day its around 30 degrees celcius
Every day its around 30 degrees celcius

I start to search for a solution. On blogs and on Youtube videos the advice was to replace the thermal paste between the processor and the heat pipe. Thermal paste is a sticky solution that helps to transfer the heat from the processor to the heat pipe.  Apple doesn’t make their own laptops. They hire a company in China to do that work. The problem is that this company is using a low-quality cool paste that’s too thick, has bad thermal performance and it will lose it thermal conductivity over time. It’s total garbage. The solution is to replace the thermal paste with a high-quality brand. I searched for what kind of high-quality thermal pasta is available in the city. For around ten dollars I bought a small tube of Arctic Silver 5.

I removed the heat pipe and with alcohol, I cleaned the old thermal paste off the processor. There was indeed too much crappy thermal paste. It was everywhere. After everything was cleaned I applied a small drop of Arctic Silver on the processor and put the heat pipe back. It was a disaster. The MacBook was running awful. I removed the heat pipe again and saw the problem. I did not apply enough Thermal Paste. There was a big part of the processor not covered. I applied some more of the Arctic Silver and put the heat pipe back.

Wow. That was is big different. The MacBook feels snappier. With the old thermal paste, the laptop had hiccups when it had to do heavy graphics. But now it’s fluent. Lets put the MacBook to the test. Let’s encode some videos. My video encoding software only uses the CPU for its task. The GPU is almost running idle. This little adjustment is a big success.

One of the advanced of having a unibody computer is that the whole enclosure is a heatsink. This is also a disadvantage. Sticky sweaty palms. The whole laptop was feeling like a small backing plate. Not comfortable.  So I was looking for a solution to make the complete Macbook feel cooler and more comfortable at the hands.  In the local hardware store, I bought for one dollar a 12CM fan and hooked it up on the most worthless power supply ever. Don’t understand me wrong. The laptop was running great with the new thermal paste. It could run at full power. But it wasn’t comfortable to put your palms on the Macbook. So the fan was keeping the enclosure cool.

But the bottom plate of the MacBook Pro was still running super hot. I want the airflow of the 12 cm fan also to flow under the laptop. So I started to put things under the Macbook: Little blocks of plastic, a Bluetooth speaker or a coffee cup. It didn’t work. I had a cool laptop. But every time I moved the laptop it fell off its temporary plateau. When I was typing the whole laptop was wobbling. Let’s search for what kind of solutions exist to lift the laptop higher, but that I’m still capable to use the laptop without an external keyboard.

I will spare you the time I spend in searching for a solution. I read blog posts. I watched the videos. All the collected information I processed for a week. After that, I made the decision to buy the Xuenair MacBook Stand. A massive block of aluminum with a hinge. I paid 20 dollars for it.

The hinge makes the stand portable. You can fold it flat and put the stand in your bag. You can also fold the hinge up and use it as an iPad stand. The hinge is moving stiff so you can adjust the angle.

Now there is enough space under the Macbook for a good airflow. The hole at the back of the Xuenair helps with the cable management.

The chin of the laptop is close to the table. So I can use the trackpad and the keyboard while my arms are resting at the table. Not only does the Macbook got a better airflow under the enclosure. But the screen is now higher. It’s much more comfortable to work for a long time. I can hold my neck in a more natural position.  The stand is rock solid. I can type for hours and the MacBook is not wobbling. I think the Xuenair is a great product. I don’t have yet any experience with traveling. The stand is around 400 grams. Did I ever tell you that working with the combination of a trackpad and a mouse at the same time is god-like?

In the history, the GPU was mostly used only for games, acceleration of video playback and doing the graphical user interface.  Nowadays the GPU also responsible for heavy calculations. Take a look at the video editing software Final Cut Pro. It’s using the GPU to do the rendering of the videos, the analysis of the stabilization and the encoding of the final video. The CPU and the GPU are both used to give you a better experience. More and more the GPU is responsible for heavy repeating calculation task. In the first years under OSX OpenCL was responsible for this. Last years Apple is shifting to Metal for this GPU supporting calculations. The arrival of a Machine Learning Module in Mojave OSX 12 will accelerate the use of the GPU in your computer. The GPU will help the Apple Photos application for recognizing faces and objects in your pictures.

Let do some quick tests. This is not a hardware website where reviewers are doing hours of testing. Those are my own quick tests. I’m doing this for fun.

The Macbook is doing

  1. Final cut pro 4K export. This is using the CPU and the GPU;
  2. Permute HEVC encoding. This program is only using the CPU. The story is that ffmpeg isn’t using the GPU because of the low video quality in HEVC;
  3. Quicktime screen recording. This program always pushes the GPU frequency up to the maximum 1.1Ghz.

You can see that the processor is using around 30 watts. The GPU is running at 1.1 GHz and the CPU is running around 2.7 Ghz. Still in Turbo boost mode. I still get more CPU processing power than I paid for. But I don’t get the full 2.9 GHz.

Furmark is known as the GPU killer. It pushes the limit of your GPU. If your GPU can run a long time at a high load and a high temperature. Then you can assume it’s a stable and good GPU. It will be not the first time that a GPU is killed by the Furmark. So be careful.

  1. Final cut pro 4K export. This is using the CPU and the GPU
  2. Permute HEVC CPU encoding.
  3. Furmark running at 1024×640

This is interesting to see. The CPU is running now at 2.1 GHz. That’s under the base clock speed of 2.4 GHz. The GPU is running at 0.95 GHz. Lower than the maximum speed of 1.1 GHz. Is the processor throttling?  And that is something I want to know. Why is the processor not running at full clock speed? The total power consumption of the processor is 26 watt. Lower than the previous test.

Is there another reason why the processor is running slower. Is Furmark using all the memory bandwidth and the processor forced to run slower to keep up with the memory requests? But nobody will run Furmark in real life. So this is not an honest test.

After four years I have to realize that my MacBook Pro is an old machine. Its a great machine for my daily life. But for hardcore calculations, I can feel the machine is sludgy. If I do one task at the time the machine can keep up with my needs. Most video encoding I’m doing when I’m at sleep or when I’m not behind the computer. It takes some time. But I will get there.

The small adjustments I did to let the machine runs cooler is helping. The machine feels snappier because I replaced the thermal paste. The machine feels cooler because of the fan and the stand. The stand also improved in handling the machine better.

I received the Jack by Podo labs – My opinion

This is not a review. But my story and opinion about the Jack. The Jack is a device that can turn every wired headphone in a Bluetooth headphone. You just plug the jack plug of your wired headphone in the Jack. (Maybe that’s why it is called the Jack?) The Kickstarter page showed a story that Podo Labs has the experience to make this Bluetooth device and bring it to the market quickly. The main reason I backed this project was that you can turn the Jack in a transmitting mode. So I can connect the JACK with a wire to any television, radio or computer and it’s transmitting the sound to another Bluetooth headphone. Handy when you have a long flight but you don’t want to be bothered by cables.

In the winter of 2017, I backed the Jack on Kickstarter. It’s not my first rodeo on Kickstarter. I have backed a lot of projects on Kickstarter. Fortunate for me I received all the things I backed. Maybe it’s luck. Maybe I can feel if a project will be a success. I also backed the PODO camera on Kickstarter. From the same makers as the Jack. But shortly after I received this camera I already broke it because of the poor quality of the plastic used by Podo labs. I asked about the warranty. Podo told me that providing that was not a problem. I only need to ship the camera back to China. The shipping cost was higher than buying a new camera. So I put the Podo camera in a box and never took it out again. I only need a small plastic piece. Maybe one day I can print this part with my 3D printer.

The promise on the Kickstarter page was that the Jack would be shipped in the summer of 2017. Podo labs bragged that they had the experience with previous products. So shipping the Jack on time was easy as pie. The Summer came and went. I saw the autumn. I saw the winter. I welcomed 2018. Sporadic I received an e-mail that Podo Labs has productions problems. In every e-mail, they send to there customers was a story about delays but with the promise that the Jack would be shipped soon. When Podo Labs put the Jack on Kickstarter they still didn’t fulfill all the backers of their latest project. People were still waiting for their Podo camera.

In October 2017 Podo Labs announced their next project on Kickstarter: The Belle Bluetooth speaker. People were still waiting for their Jacks. People were still waiting for their Podo camera. In the comments section on Kickstarter people even start to talk that Podo Labs is paying the debts of the previous projects with the gainings of the latest Kickstarter projects. Sounds like a Ponzi scheme. You keep the public interested in delivering products that are paid by others. I don’t know if this story is true. What I know is that when a company is communicating with their customers on regular basis and tell them the truth that you will get goodwill. But that’s what Podo Labs didn’t do. They kept silent. You have to hide something as a company if you keep silent for weeks, or even months.

I already took my losses. I expected to never see my Jack. This will be my first failed Kickstarter project.  Kickstarter is an investment. So I can’t cry like a baby and ask for a refund. The 25 dollar I invested is lost, but I gained a experience. Why are companies returning to Kickstarter with new projects? Kickstarter is a platform to kickstart a company. Why return?

I was surprised that this week there was my mailman in front of the house. With a small envelope. What could that be? A small envelope with an utterly smashed small box in it. I received my Jack. Without any notice, Podo Labs send me a Jack. I didn’t receive any tracking code. What a surprise.

What did I receive? A black Jack, a USB charging cable, and a silicon protection cover. Everything was protected by some bubblewrap plastic. There is no manual in the box. Something I don’t see as a problem. I keep my manuals digital in Evernote. The paper manuals I always throw away.  I can’t remember that I order the silicon cover or recall the reason why I received the cover. I can’t find any proof that I paid for it. So thank you Podo.

On the left side of the Jack, you have a stereo 3,5-inch jack plug and a micro USB charging port. When I plug the Jack into the USB port of my Macbook there is not USB device visible in the system information. So there goes any change for an easy update of the firmware or use the Jack as an external DAC player.

On the right side, there are three buttons and a hole for the RGB led. The led can show in different colors the state of the device. The big button functions as the power button and as the play stop button. The small buttons are for the volume control and the control of the tracks.

My eye was caught immediately by the two screws. I felt a big urge to get my screwdriver set (XIAOMI Mijia Wiha. The best screwdriver set ever) and open this puppy. Here I found the first problem. The enclosure of the Jack is only held together with one screw. The second screw is loose in the plastic. I will show you later why.

Opening the Jack is a feast. It’s only two plastic parts. The battery and the circuit board are sandwiched between those two plastic parts. I was afraid that it would be a problem to open the Jack. But as smooth as warm butter the two parts slide from each other.

Seeing the circuit board give me a positive feeling. I don’t know if it’s of good quality. But it looks easy to repair or to modify. You can see there are a lot of test pins on the circuit board. But for now it’s a little happy board.

Jack by Podo labs – Circuit board

The connector for the headphone only has three pins. So any headphones with support for a microphone won’t have microphone support with the Jack. You cannot use the Jack for making phone calls. The antenna is a separated part. I wonder why? It’s cheaper to etch the antenna on the circuit board. But Podo Labs decided that the antenna is a separated piece that’s connected to the circuit board with a cable. I don’t mind this decision. It looks like more quality. But is it reliable?

UPDATE In the comments section MadJo mentioned that the Jack has support for a Microphone. I got my flashlight and took a closer look nearby. Yes. There are four pins in the jack plug. The Jack is supporting headphones with a microphone. I paired the Jack with my iPhone and I could make recordings in the IOS 12 (beta) Voice Memos app. Both clips are lossless. That the sound over the Jack is in a lower quality is I assumed something in the Bluetooth protocol. I don’t think its the Jacks fault.

The battery is a 300mAh Li-Po battery. I think enough for a long day of listening to podcasts, watching Youtube and listening to music. The battery is easy to get on the market and has a protection circuit.

When I was putting the Jack back together I didn’t feel comfortable. There is a change that the metal clip can touch the circuit board and cause a short-circuit. Maybe the protection circuit on the battery will prevent a big spark. But its something to keep in mind when you are disassembling or assemble the Jack.

What I think is a problem with the Jack are the fragile pillars that are holding the screws. In my Jack, one of the two pillars was already cracked. So the screw can’t hold on it properly. I hope that Jack will release the STL files. Then I can print my own enclosure with my 3D printer when the enclosure breaks. The Sandwich construction also gives me the opportunity to design my own enclosure for the Jack. maybe I will dive into that later.

Someone was maybe lazy in the Podo Labs factory. On the battery is a strip of tape. Maybe to secure the battery in the enclosure. But the protection foil is still on the tape. Did someone forget to tape the battery?

My first impression is that the Jack looks easy to repair or to be modified for future projects. What I really hope for is that I can use the Jack as part of a vlogging setup. The Jack can be used as an audio transmitter. So if I put a microphone in the Jack. Can I somehow capture this audio stream and record it on a laptop or a phone. Or a second Jack (or an another Bluetooth receiver which I can use to connect). This project goes on my list.

How does the Jack sound? I have to be honest. Better than I expected. It sounds good. Podo Labs didn’t step into the trap to make it too bassy. The market is already flooded with too many devices that are too bassy. The Jack sounds very natural. I’m happy with the sound. The Jack gives me the freedom to choose which headphone I want to use.

One of the reasons that the Podo was delayed by more than a year is its clip. The clip feels badass. It’s strong and feels like a part of something that’s used in the Starship Enterprise. I can play for hours with that clip. If other manufacturers are reading this story. If you ever want to put a clip on your product. Look at the Jack. That clip is pure art.

In the comments sections, people complain about the range. After one meter the sound already starts to crack. I did also this test. My range is five meters. That’s acceptable. I can reach all the corners in this room and I can use the bathroom. Don’t forget. Wireless communication depends on two peers and the band. Maybe they use a shitty phone or live in an area with an overcrowded 2.4Ghz band.

I won’t back quickly a new project on Kickstarter. Lately, I have the feeling that Kickstarter is not anymore a platform for finding the funding for a product. But its become an advertisement platform to promote a product. A lot of products don’t need any big investment to get realized. For example wallets and bags. After the Kickstarter is finished that product is ship right away. The designs and factory lines are already in place. They just need Kickstarter to reach the big public. It’s also really shady why successful companies use Kickstarter over and over again for there new project. For example Pebble. The first time its understandable. They need the funding for a new project. But later they did it again. And the third Kickstarter was a total disaster. Pebble was already bankrupt when they started this Kickstarter. Think about it. Why are companies returning to Kickstarter. If a company is healthy they can use the normal retail channels. You as a customer will have more rights.

I have seen a lot of things on Kickstarter that interest me. But now I’m withstanding the pressure to backed those cool things. I wait till the Kickstarter is over and the products are available in the normal retail. I pay a little bit more. But now I get a legal warranty on the product. I don’t need to wait months before the product is realized and I’m protected by my credit card company if the products aren’t delivered.

How can you update the firmware of the ZOOM H1N audio recorder

One of the best and cheapest stereo audio recorder is the ZOOM H1. This little device is now for many years on the market. It didn’t need a refresh because it was almost perfect. But the Japanese company Zoom surprised everybody when they released its successor. The Zoom H1N. But before the H1N is almost as perfect as his big brother the H1 the last bugs need to be crushed. Zoom released firmware version 1.19.  I made a video which helps you to update the firmware on your Zoom H1N. What I found out is that you need a good formatted memory card or the update doesn’t start. I highly recommend that you use the SD Memory Card Formatter to format your memory card.

After the update, I noticed that the Zoom H1N was also faster with booting up. I like to get a free performance boost.

Walking in the Tao Dan park, Ho Chi Minh City

This blog post is dynamic. It will be edited with the latest information. You will find a changelog at the end of this blog post.


The meetup group Thanh Pho Ho Chi Minh Walking for health Meetup-Tao Dan park is bringing people together every 12 weeks for a walk. But some people disagree that every 12 weeks is enough. Every week or every two weeks is better. We try to contact the administrator of the meetup group. But this person stayed silent. So this is a shadow document with more information about the weekly walking group.


After a busy week its good to have a walk. You can use it to learn and practicing a new language, make new friends, exchange information about cultures, try new food, See people practice different sports or just walk in silence.


Every Saturday morning. We gather at 7:00 (AM) in the bird cafe. Around 7:15 (AM) we start walking in the Tao Dan Park. Around 9:00 (AM) we sit in the Bird cafe for coffee and/or tea. Some members of the walking group start at 6.00 (AM) with a sport like running.


The walking is in the Tao Dan Park in District One. This park is central in Ho Chi Minh City. The park is situated behind the Independence Palace (aka Reunification Palace / Dinh Thống Nhất) As address for your navigation system, Taxi, Grab or Aber you can use the address 57 Nguyễn Thị Minh Khai, Bến Thành, Hồ Chí Minh, Vietnam

Bird cafe

Every morning bird lovers gather in the bird cafe. They bring a cage with their beloved bird. A good place to gather for the walk. More information about the bird cafe can be found at -> Cà phê chim Tao Đàn, thú vui tao nhã của người Sài Gòn (Sorry. The text is in Vietnamese)


If you come with your bike. Then you can park at two places in the park. The parking in the east is only a 10-meter walk to the Bird Cafe. The cost for the parking is 5.000 dong.


In the Bird Cafe, you can buy coffee. The price is a little bit higher then you pay on the ‘street’. A coffee with milk is around 20.000 dong.


Walking makes you hungry. In the park is a small stand that sells warm soja yogurt with caramel. Taste really good and is not so heavy for the stomach. The price is 5.000 dong for one bowl.


In the park is a FREE public toilet. It’s clean. Separated for ladies and gentleman. You are not allowed to wear your own shoes inside. Make use of the free provided flip-flops.

Korte Science Fiction films

Iedereen die mij kent weet dat ik erg van Science Fiction films hou. Helemaal als ze in de film proberen het zo realistisch mogelijk te maken. Jaren geleden zag ik de korte film “True Skin” voorbij komen. Ik was de video al een tijdje vergeten tot een oud collega mij HYPER-REALITY toonde. Zo kwam ik tot deze collectie van korte films waarvan ik denk dat die de toekomst aardig dicht benaderen.

True Skin

In de toekomst is het modificeren van lichaamsdelen de normaalste zaak van de wereld. Maar wat heb je aan al die technologie als er op je gejaagd wordt.


Langzaam nemen de robots de wereld over. Maar gaan ze deze strijd winnen?


Augmented reality in een overdrijf. Kan jouw identiteit makkelijk gestolen worden?


Daten in de toekomst. Het is een spel. Kan jij een vrouw versieren als je informatie over haar hebt?

Een siliconen sok voor jouw 3D printer.

De eerste 3D printers maakten gebruik van ABS. Deze op oliebasis gebaseerde kunststof was ingewikkeld te printen. Je moet gebruik maken van een verwarmd printbed om te voorkomen dat jouw print kromtrekt. Daarnaast komen er giftige stoffen vrij bij het printen van ABS.

Als ik ABS print gooi ik de ramen helemaal open en sluit ik de deur naar mijn print ruimte. Ik wil niet in de buurt zijn. Natuurlijk heb ik de fout gemaakt dat ik bleef kijken bij een ABS print. Dit heb ik moeten bekopen met een heftige hoofdpijn voor de rest van de dag.

PLA is een kunststof die wordt gemaakt van plantaardige grondstoffen. Ze zeggen wel eens als je met PLA print dat het ruikt naar popcorn. Ik vind dit onzin. Maar het stink niet. PLA heeft als nadeel dat je het meteen wilt koelen. Daarom hebben de goede 3D printers allemaal een filament cooler. De Kodamo trinus 3D printer heeft zelfs een 360 graden cooler. De koele lucht wordt rondom op het object geblazen. En laat hier nu het probleem zitten. De cooler is zo goed dat de printkop ook afkoelt. Soms koelt het wel af tot 20 graden onder de ingestelde temperatuur. Dit kan problemen geven met de stevigheid van het geprinte object. De nieuwe laag heeft door de lage temperatuur niet goed kunnen hechten aan de onderliggende laag.

Dit probleem kan je oplossen door de printkop te voorzien van een siliconen kapje wat rondom te printkop gaat. Mijn printer heeft geen problemen meer om de printkop op de juiste temperatuur te houden. Een tweede voordeel is dat de printkop schoner blijft. Verdwaalde print filament blijft niet meer plakken aan de printkop.

Ik heb drie siliconen sokjes van E3D (LINK) voor een paar euro gekocht vanuit Engeland. Voor mij nu al één van de beste aankopen voor mijn 3D printer. 

Test je kleuren laserprinter

Een normale laserprinter die alleen in het zwart kan afdrukken is een apparaat wat altijd werkt. Maar een kleurenlaserprinter is een verhaal apart. In dit apparaat is bijna alles in viervoud gebouwd. De drie kleuren en zwart hebben alle vier een eigen afdruk gedeelte. Een eigen toner en een eigen drum. Vier keer zo veel kans op een storing. Vier keer de aanschaf van een toner als deze leeg is. Deze vier componenten moeten precies op elkaar afgestemd zijn. Anders heb je al een afwijking in jouw drukwerk.

Deze vier moeten heel goed op elkaar zijn afgestemd.  Dit is voor mij de reden dat ik mijn kleurenlaserprinter heb omgeruild voor een normale laserprinter. Vier keer zo klein.

Wil je toch kijken of jouw kleuren laser printer goed werkt? Dan kan je de volgende PDF downloaden en gebruiken. Je kan zien of de vlakken egaal zijn. Of de printer randloos kan afdrukken en of de printer niet overlapt in de kleuren.


Hoe ik de styles van mijn ebook reader heb gerepareerd

Een nieuwe stylus van Sony voor mijn PRS-350 ereader

Vorig jaar beschreef ik het probleem met mijn Sony PRS-350 ereader. De stylus brak zonder enige aanleiding af. Onderaan mijn blogpost begonnen de reacties te verzamelen. Ik was niet de enige met het probleem van een gebroken stylus. Het kreeg niet voor niets de naam “Sony broken stylus syndroom”.

Omdat ik me toch begon te ergeren aan het uitzicht op mijn e-reader besloot ik vorig jaar in september het probleem rechtstreeks bij Sony te melden op Twitter.

Jammer dat sony het probleem blijft negeren
Jammer dat sony het probleem blijft negeren

Tot mijn verbazing kreeg ik een telefoontje van een manager bij Sony Nederland. Hij was door de Sony Webcare medewerker aangesproken over mijn tweet. Het goede nieuws is dat ik van hem een kosteloos nieuwe stylus krijg opgestuurd.  Een andere opdracht die hij zichzelf had gegeven was het onderzoeken waarom een nieuwe stylus bij 22,40 kost. (14,90 + 7,50 verzendkosten). Hij was het met mij eens dat dit  een veel te hoge prijs is.

Sony heeft mij gebeld

Een paar dagen later stond de postbode aan de deur. Post van Sony. Een splinternieuwe stylus. Ik wil Sony met terugwerkende kracht nog ontzettend bedanken voor het oplossen van het probleem.

Nu zullen sommige van mijn lezers afvragen waarom ik een stylus gebruik? Ik lees veel boeken in het Engels. De Sony PRS-350 ereader heeft een ingebouwd woordenboek wat mij kan assisteren bij Engelse woorden die ik niet ken. Even met de pen dubbel tappen op het woord en de vertaling komt te voorschijn. De e-reader gebruikt voor zijn touchscreen niet de techniek die bij Apple en Android apparaten wordt gebruikt om een aanraking op het scherm te registreren. Dat is technisch niet mogelijk door de dikte van het elektronische papier. Sony lost dit probleem op door rondom het scherm de aanraking te detecteren met een onzichtbaar infraroodveld. Mijn vingers zijn helaas te dik om elke aanraking goed te detecteren. Vandaar het pennetje.

Waarom schrijf ik er zo laat nog een blogpost over dit probleem? Omdat het probleem zich nog steeds voordoet. Ook in 2012 heb ik reacties op mijn blogpost gehad van lezers met afbrekende pennen. Op is niets gedaan aan de prijs en verzendkosten van een vervangende stylus. Die kost nog steeds 15 euro plus 7,50 euro aan verzendkosten.  Een hoge prijs voor een product wat zeer goedkoop te produceren is en door de brievenbus past.

Mijn ebook reader ziet er zo niet uit

Sony Broken Stylus Syndroom – Sony PRS-350 e-reader

“Neen Meneer. Op de stylus geeft Sony geen garantie. Maar u kunt op onze webshop voor 23 euro een nieuwe bestellen.”

“Ooh,  Of u garantie heeft als u een nieuwe stylus bij ons koopt. Dat weet ik niet.

Het internet staat er vol mee. Boze klanten die de Sony e-reader PRS-350 bezitten waarbij op een onverklaarbare wijze de stylus breekt. Op zijn Nederlands wordt de stylus ook wel het pennetje genoemd.

Ook bij mijn e-reader is dit gebeurd. Lekker op de bank lag ik boek te lezen op mijn Sony PRS-350. De e-reader in mijn linkerhand. De stylus in mijn rechterhand. Ik lees boeken in het Engels. Weet ik even een woord niet. Dan hoef ik alleen even dubbel te tappen met de stylus. De e-reader toont mij dan snel de Nederlandse vertaling. Erg handig.

Minder handig was dat opeens de stylus in twee delen lag. Eerst dacht ik dat de schroefdraad los zat. Helaas bleek dit niet zo te zijn. Zonder enige kracht te zetten lag die uit elkaar. Als je de afbeeldingen bekijkt lijkt het wel of het kunststof van de stylus verkeerd is gegoten. Het is een productiefout.

Mijn eerste telefoontje naar Sony

Gelukkig geloof ik in de goedheid van de klantenservice van Sony. Dus ik bellen met de helpdesk van Sony. Daar werd mij verteld dat voor garantie afhandeling ik het beste terecht kan bij het bedrijf wat de garantie doet in Nederland. . Dan daar maar mee bellen

Tweede telefoontje naar FRS europa

Voor garantie en reparatie gebruikt Sony de firma FRS Europa in Almere. Te bereiken op 036-5388853

De dame die ik aan de lijn kreeg klonk alsof ze geen plezier heeft in haar werk. (Zal zeker in Almere wonen?! ) De belmiep vertelde mij al meteen dat er geen garantie op een stylus zit omdat het een accessoire betreft. Maar ze kon mij voor 23 euro een nieuwe toesturen.

Derde telefoontje naar Sony

Maar weer met Sony Nederland bellen. Waarom ik bel. Nou omdat FRS Europa mij niet wil of kan helpen. De verkoper reageerde wel dat hij 23 euro voor een nieuwe pen raar vond. Ik kan beter de pen rechtstreeks bij Sony kopen voor 15 euro. Wat die belkees mij niet vertelde is dat de website ook nog 7,50 euro aan verzendkosten rekent. Ja, 7,50 euro om een stukje metaal en plastic te versturen. Uiteraard werd ik hier niet blij door.

Ik kon het niet laten om het te vragen. Krijg ik op een losse stylus wel garantie? Nou, dat kon de belkees mij niet vertellen. Maar wel dat er op de stylus die bij de e-reader zit geen garantie zit. Dat de e-reader zo is ontworpen dat de stylus een onderdeel van het design is telt niet mee.

Ik ben niet alleen

Als je op dit probleem gaat Google’en zul je zien dat ik niet de enige ben. Bij heel veel klanten van Sony breekt de stylus. Er zijn nu zoveel pagina op het internet te vinden dat het probleem geen incident meer is. Het heeft zelfs al een naam gekregen; Broken stylus syndrome

Fix your own stuff

Ik ga nu niet meteen 23 euro betalen voor een stukje staal en plastic. Dat doe ik al voor Apple producten. Sony heeft het nog niet verdiend dat zij ook dat prijsmodel mogen hanteren.

Wat ik gedaan heb is een fijne kleine schroef in de pen draaien. Nu heb ik toch een stukje houvast om de pen uit de e-reader te kunnen trekken. Het is meteen ook een opening voor gesprekken. Als mensen mij vragen waarom er een schroef inzit, kan ik ze vertellen hoe hard het garantie beleid van Sony zuigt.

Wat kan ik doen?

Erover bloggen en twitteren. Ik verdien nog steeds een leuk zakcentje aan mijn blogpost over KPN digitenne. Dan ga ik de inkomsten uit deze blogpost gebruiken om te sparen voor een nieuw pennetje. Ik zet binnenkort een knalgele schroef in de e-reader. Mensen mogen mijn schroef zien 😀

Weet je. Ik cc deze blogpost meteen naar Kassa en Radar. Kunnen zij in de komkommertijd kijken of ze hier een item aan durven te wagen.

Helaas heeft Sony al jaren zijn glans verloren. De garantie en communicatie hebben zij uitbesteed. Sony is een doorgeefluik geworden van slechte producten. De afgelopen weken heeft de communicatie-afdeling van Sony al bewezen hoe slecht zij de afhandeling van de Playstation Netwerk heeft afgehandeld.

Geef mij nog een reden om Sony producten te kopen?

UPDATE 10 februari 2012

Vorig jaar heb ik door deze blogpost van Sony een nieuwe stylus ontvangen -> Een nieuwe stylus van Sony voor mijn PRS-350 ereader
