Let's try again...
Shematics are still missing, but system is "ugly linear" 7812 based with 10x NiMh cells, headlight have DX led driver 3x 1w led and taillight is made from PC-motherboard found LD1117 chip with some SMD reds. Near charge plug is power off switch and chargeplug turns off ground connections so fidlling with charge wont blew anything off. All parts except leds are recycled from trash and still waitting new shiny samples so I get some boost. (bike parts are sadly bought from several shops...)
Shiny enough for city and touring.
Yep, it lost power and even my "lunch_box" wont help several hours out under minus ten... butt is still visible, ;-).
Uh, I hate redo wiring's, next bike frame I will start from wires and use better connectors.
Yep, it's all you need to feed your lights... LunchBox but it still too cold inside (far left is nice)
It keeps power leds happy.
Charge-plug with extended cable. Under charge plug is "load side" off switch but charge-plug disconnect batteries from led anyway cause system is not polarity protected.
Still need to make better box for batteries and build switching regulator (National and Ti are so nice to send samples) if it can hold fast transitiens change and batteries holds "spikes" then I have ideal system for all year touring. Oh, automatic on/off switch is still missing and ... daydreaming. :tired:
