Working on a smart watch project for students to potentially do. These GCA901 round displays are crazy cheap now. Just managed to get this one and the touch working with and ESP32S3, now to start designing a PCB and housing for it.

This week I've got the kids making and coding these LED displays. Just a 16x16 neopixel matrix, an esp32, and a battery with charging circuit.

So we got the robots balancing... more or less!

Now the kids just have to get the remote controls working and we'll have the RC balance bots in the bag.

Everything fits in the submersible my students designed. Camera and serial connection to the umbilical work.
Just need to perfect the waterproof end cap, which will also mount the thrust motors.

Looks messy as hell, but this is the sub successfully communicating 2 ways with a receiver through 30m of cable.

Students wanted to make a submersible so I've been working on this.

Testing out the ballast system, thrust, and the electronics to drive them. Looking good so far.

Diaphragm pumps for the ballast are so fast, shame they can't run in reverse so need two.
