The Raspberry Pi on Square One had been running very well. I’d added some actuators for the Tidy Up the Toys challenge. These enable Square One to pick up wooden blocks and stack them. This worked pretty well but I noticed that the Raspberry Pi reported “Under Voltage” errors sometimes. Oops!

Here’s what I did to investigate and fix the problem.

I’ve finished the Nerfwerfer and it’s all wired up ready to Feed the Fish.

Here’s the first video of the mighty Nerfwerfer which I’ve created for the Feed the Fish PiWars challenge.
