@ZodiusInfuser @pimoroni I could see using the potentiometer for tuning feedback loops. It would also pair nicely with the Bench Power Supply module.

Had to use two Tiny 2040s to get the laptop to communicate with the TV.

Gesture controlled Android TV!

Created using mediapipe and python on a laptop.

Working a bit better now that I've swapped the lipo for a wall based power supply.

@gammapeak Thank you, the bellows have a servo inside them.

[RedBrick @Red0Brick]

Inspired by mitxela's midi slide whistle, here is my take on it using @pimoroni's tiny2040 to drive servos and Pure Data on a laptop to attempt to to self correct its pitch - needs a bit of work.

That walks!😀

@pimoroni looking very smart!

@NeaveEng @MarkMellors I'm currently just using PLA, it all seems to work well for now, my original issue was just not thinking through my track design, but it may change as the segments wear.

[RedBrick @Red0Brick]

Spent a long time trying to tension the tracks, turns out the problems was them being able to flex too much.

[RedBrick @Red0Brick]

@MarkMellors @NeaveEng My new set of tracks have a very slight lead-in but it's mainly fixed by the tracks now holding the sprockets in line as before, due to them being so thin, they would flex to a point that put the next tooth outside the track.

Redbrick is now both more red and more bricky. #PiWars

[RedBrick @Red0Brick]

It can now move at full speed without pulling it self apart, may actually be useable for #PiWars

[RedBrick @Red0Brick]

It moves! Yet to get it to full speed.

[RedBrick @Red0Brick]

@youngincheshire Good idea, in currently relying on overly tensioned tracks and the flex in the sprockets but I think I'll end up having to think about it.

[RedBrick @Red0Brick]

Turns out tracks are quite hard to design from scratch. #PiWars

[RedBrick @Red0Brick]

@PiDrogen Whilst looking at farming robots I realised that alot of tracked ones had a large sprocket and thin track width and I can't easily do that in Lego.

@DrLucyRogers Good morning
