Breadboard Modification

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...

It’s Adowable

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...

Some Things Don’t Change

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?...

Drawing my Pareidolia

So, I swear the original on the left looks more like a grumpy man in real life than it does in the photo, but anyway, that’s a photo of a piece of popcorn...

Working on the Sonar Deck

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...

This and That

Well, things have been going a bit slowly for a few days. I discovered that I very nearly made a huge mistake on the robot. I thought I would be able to shift the position of the bumpers upwards to clear the USB port of the Pico...

Added the Bumpers

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...

Working on the Robot

So, I’m really sleepy right now. I didn’t sleep that well and then I spend all day working on my new robot. And then instead of keeping my head down, I decided to write this. I started with the metalwork for the front and rear bump sensors...

Boards are Done

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...

New PCBs

I spent most of today making up the boards for my new robot and, oh boy! Maybe it’ll be fine...
