@timchubb – nice work! I’m no stranger to copper tape-based circuits (my nerdy mates at the local electronics group seem to think I do little else at the minute!) and love your modified house!

I have tried using bare conductive paint (and even a “better/less resistive” homebrew concoction) to print circuits but found resistance to be a problem over long runs (especially when connected with microwire which, itself, adds quite a bit of resistance). Voltage drop is a real pain when trying to daisy chain LEDs! I had some moderate success by electroplating copper over the painted tracks, but that was more difficult and messy to do than using 3mm copper tape so gave it up as a bad job.

I’m intrigued by your picture – is it a single-colour or an RGB LED? It looks like a pair of single colour LEDs; if they can, indeed, be changed (programmatically) to be any colour, please let me know – I’ve been looking for a two-wire colour-change LED for aaaagggges.
