I had a very informative hacking session tonight and quite a few trips down rabbit holes. I decided to do a little side project: A couple of big hardware buttons that can control Zoom mute/unmute and screen share on/off states on my laptop. I spend most of my days on Zoom and it would be very handy. Easy, right? Well, it turns out that it’s not that easy. First thing I did was confirming that Zoom already had global hot keys for the controls I needed. Found them under Settings > Keyboard Shortcuts. Looked good. ...

Added some logic to the LED rainbow so it dims slowly over the course of the hour before turning off for the night, and same in the morning. With that, I call this project complete! Decided to add Bluetooth control to the LED Rainbow. Every once in a while we need to change the go to sleep and wake up times and M wants to be able to control the colours from her iPad. ...

I have been working on an LED rainbow project for M. It’s really coming along and I also managed to get an RTC module soldered on to the board tonight. Everything was going well until the sketch upload to the Trinket failed. Apparently Adafruit Trinket has this issue where it’s easy to override the bootloader by mistake. I think it happened because I was using 99% of progmem. Solution is easy, you just hook up the Trinket to another Arduino and use a little sketch to burn a fresh bootloader. Problem was: Trinket was already soldered on the prototype board! ...

I could watch this thing tick all day. Weirdly satisfying!

Flipclock prototype is working well. Had to modify the front panel design and reprint, but now it’s moving smoothly. Next step is assembling the embossed digits and minute motors. Flipclock digits are assembled! They are looking clean and beautiful. I will be assembling the full device tomorrow evening and hopefully have it functional. ...
