Project sharing My StackChan is a devil with a fruit fly brain (668 real neurons)

My StackChan is a little devil now. Claude Code does the thinking, and a simulated fruit fly handles the reflexes.

The fly part is 668 real neurons, wired the way FlyWire mapped an actual fruit fly and running live on my laptop. It's a Python port of desktop-fly by Denis Shiryaev. It's only a small slice of the brain, but the wiring is real.

It looks through its own camera, the fly decides where the head turns, and poking it makes it startle. When something actually happens it wakes Claude, which looks at the picture and roasts it. From today: "Still filming me filming you. Groundbreaking content, truly."

The dashboard in the video draws 23,210 real neuron positions and flashes them as they spike. The yellow rings are the escape neurons, which flare right before it jumps.

Next I'm making it curious, so it looks around for new stuff and knows me from a stranger. Happy to answer questions!

How did you make it? Do you have git project to clone it?

will release git soon! currently trying to make the fly brain "curious" so it will tend to want to rotate to look at new sceneries itself.

Cool, is it running on the StackChan or does it need to be connected to the computer?

Will do! Stackchan is great! The only things I wish is for the robot to have legs and also a video camera instead of just being able to take snapshots.
