Today we’re releasing the circuit diagram for the Interactive LED Dining Table (aka our kitchen table).
We’re releasing this as a free (and fully unsupported) project design, so… “Have fun, kids!”
The circuit consists of 16 individual analog computer nodes that are connected together in a 1-D chain.
Each node has this circuit diagram, driven by a quad op-amp chip, taking input from a photodiode, and storing the result in an analog variable (integrator). You can also download a PDF of this circuit diagram.
