Making nice-looking and interactive diagrams for your PCBs
I have always liked pinout diagrams like this: Arduino Nano Pinout. Source: http://www.pighixxx.com/test/wp-content/uploads/2014/11/nano.pngThey work quite well, there is all the information and they look nice. However, they work only when you have pins on two sides of the PCB and once you squeeze too much information…

Raspberry Pi boosts Pi 5 performance with SDRAM tuning
tl;dr Raspberry Pi engineers tweaked SDRAM timings and other memory settings on the Pi, resulting in a 10-20% speed boost at the default 2.4 GHz clock. I of course had to test overclocking, which got me a 32% speedup at 3.2 GHz! Changes may roll out in a firmware update for all Pi 5 and Pi 4 users soon. My quest for…

How my e-reader lost its stripes
I’ve been a lifelong reader, which has proved a fragile habit in our era of endless trivial distraction. While books and e-ink readers solve the problem of competition for attention, they can’t compete with a phone for convenience.
