Macroscopic Neuron Challenge with Lu.i

The Lu.i neuron PCB

Lu.i (phonetic notation of »Louis«, an homage to Louis Lapicque, who first formulated the leaky integrate-and-fire model) is an electronic neuron circuit mimicking and illustrating the basic dynamics of real, biological neurons. The printed circuit board (PCB) features a configurable, fully analog implementation of the leaky integrate-and-fire model and visualizes the internal state, the membrane potential, through a VU-meter-style chain of LEDs. The neuron emits a short pulse whenever the membrane potential crosses a predefined threshold voltage. Neurons communicate by exchanging these spikes. Multiple boards can be connected via jumper wires to form networks.

The Challenge

We challenge all participants to build functional, interesting and entertaining networks with Lu.i neurons. You have two weeks, and lots of neurons – be creative (and integrate your sensors!). Your work will be judged by the audience in a shared presentation at the end of the workshop. Everlasting glory is at stake.

Help?

First of all, come and talk to us!
Additionally, you can find more detailed information as well as a few examples for inspiration on Lu.i's github page: https://github.com/giant-axon/lu.i-neuron-pcb
