Lu.i – an Educational Neuron Printed Circuit Board

The Lu.i neurons are low-cost, palm-sized analog electronic circuits, which mimic the fundamental dynamics of biological neurons designed for educational and outreach purposes. The users can visualize and interact with the dynamics of individual neurons and small neural networks, effectively illustrating key neuroscience and neuromorphic engineering concepts.

The Lu.i neurons were created by Sebastian Billaudelle, Yannik Stradmann, and Julian Göltz from the Electronic Vision(s) and NeuroTMA groups (Publication and more Info).

The open-source and low-cost nature of the Lu.is facilitates successful applications in classrooms and workshops. For instance, the undergraduate students at the Technische Hochschule Nürnberg Georg Simon Ohm developed academic projects using the Lu.is neurons, which Prof. Axenie later showcased in his lecture on neuromorphic systems!
