For a few years now I’ve had a collection of breadboarding modules that I’ve used for prototyping. They’ve all had an Arduino Uno mounted in the top corner. Since I started using Raspberry Pi Picos, I came to the decision to replace one of the Arduinos with a Pico. So […]

So, I didn’t realise how tiny these things were. All the promo pictures have them looking like Nokia phone displays but no. They’re literally an inch square. Anyway in my last order I bought 2 of these little OLED displays because the Raspberry Pi Pico has I2C channels coming out […]

I finally got around to ordering a new roll of solder. Yes, I bought leaded solder because screw brain cells, what have they ever done for me? What I find interesting enough to spend time writing this post about is that I purchased it from the same supplier as the […]

I did a bit of work on the sonar deck for the robot. The first task after cutting out the boards was to solder the component pieces together. I use PCB material for the mechanical structure of the deck and include traces for electrical connections. The way it turns out […]

Today I spent all morning finishing off the bumpers for the new robot. I decided to try using acrylic for the actual bumpers, so the first task was to saw them out of the sheet. Fortunately the sheet had a bit that was the perfect size for the job, so […]

Yesterday I finished off most of the circuit boards for my new robot. I had to harvest some components from existing old circuit boards, notably the modular connectors I am using on the bumpers. The rest of the components were a mixture of new and old from various sources. To […]
