Another Friday, another list of cool stuff that I've read this week (I know it's tuesday, let's pretend the week was long): Aputure released new lights. I have cheap chinese lights, I've been thinking for a long time about upgrading, I'm really struggling top not click "buy now" Sarah Maddox, who happens to be a …

Crypto and kids
I was nerd-sniped (reference from xkcd) by a colleague who wanted to do a cryptographic game for his kids, for a birthday party. The idea was to have a device to allow the kids to encrypt / decrypt a message Principle It's using the Caesar cipher, which is a simple shift cipher. It's super unsafe …
Create a video lamp
I'm doing quite a lot of video conferences from home and I've decided to improve my setup, to have better quality, and ideally, at some point, be able to use it for some Youtube tutorials. I still somehow naively think I'll eventually find some time to do that... Anyway, as I've discovered recently and explained …
From better video to better still pictures
Earlier today, I was in a meeting and I was thinking how to improve the quality of my video conference that I often do from home. I was at the time especially focussed on how to improve the sound quality. After some Nerd Sniping from my boss, I ended up reading about some internal document that …
Building a microscope
I recently bought on aliexpress a powerful (and cheap) microscope. For 15 bucks however, the feature set is quite limited and it has no autofocus, meaning the body needs to be moved to put things in focus. As the official support has 2 ball joints, it's almost impossible to be accurate : when moving focus, …
Box for GoPro batteries
I recently bought a GoPro and wanted to make a box to store the batteries. To be clear, my model is Hero 4 Silver and is using these (AHDBT-401) batteries. It's easy to find the electrical properties (3.8V DC, 1160mAh, 4.4Wh), not so easy to find the physical size. Here is a quick overview of the key …
Youtube and me, second round
My first try with youtube was such a tremendous success (ahem) that I had to try again. The main problem of previous video was a really crappy sound. I did lots of tests since and discovered that my headset is producing decent sound quality with audacity. However, if I try to record directly from lightworks …
Youtube and me
I'm from a generation who was taught that the ultimate source of knowledge are the books. I managed to evolve on my own and found that internet is a wonderful place where lots of people share lots of interesting stuff. I was pretty happy with that situation : look for a blog post or an instructable, …
Screen/laptop holder
Until recently, main screen was resting on thick book to be slightly higher and end up in front of my eyes. As part of a revamp of my setup, I decided it was time for an upgrade. I had some specific needs: my screen needed to be roughly 10cm higher than desk I have a …
Designing gears with inkscape
For a hush hush project, I need to use gears and I plan on designing and laser printing them. Theory I found this old article which explains a lot on how to make gears with (older) inkscape. It relies on the following technical reference. With new version 0.91, things have been a bit simpler. Unit can …
