My last year mod for Mini-Me – Audi tuning with LED lights.
Everything is powered with 4 x 1.5 V AA batteries and controlled with low power CMOS 4013 (one battery pack is enough for 6 month usage). The lights switch automatically on (magnet sensor mounted on front wheel) and switching off automatically after 1 minute.
The electrical circuit is a simple multivibrator – unfortunately documented only in my head – so if you are interested in the circuit drop me an email and I’ll make a nice drawing.
