Circuits


NB: Unless indicated otherwise, the circuit designs shown here are prototypes that may not have been built or tested. In most cases decoupling components and/or (inter-) connections are not fully shown. Similarily associated software may not have been written (yet). However I hope they can form a basis of, or inspire, your own projects!
