There is a DC-DC convertor from about 1.5 Volt to 5.0 Volt (about 100 mA) available NCP1402. With this IC you can power your microchip with AA or AAA accumulators. I made a print for it, which can be used stand alone, or as part of other electronics. For this last option the pint can made with IC-feet 4-pins (2 pins dual in line). Interrested? Contact me.

Re: AA accumulator for your microchip
Hi Jan,
Looks very nice. I can't see an inductor, is it one of those new inductor-less designs. 100mA is quite low but not too bad at all if it's current out @ 5V.
I've been looking recently at low voltage DC to DC up-scalers for use with wind turbines, solar panels and the elusive wind band. Love to get an array of wind bands doing their thing in a panel you can simply attach you your house like a solar panel but not seen anything like this already available.

Re: AA accumulator for your microchip
Hi Ben,
There is used a coil as can be seen in the application figure below.
I'm sorry, but I'm not a specialist in DC-DC step-up conversion. Let me know when your do not need the public net for all your electronis at home.
With kind regards

Re: AA accumulator for your microchip
Hi Jan,
Hi Steve,
I was all excited to see arrays of wind bands when I saw that. Feel I might have got the wrong end of the stick
They do look good but maybe also quite expensive, I'll have a good look through, have you used them before?
My idea was something really small and simple to generate say 5V from each low energy generator source so each could be used independently or combined together to charge a phone. Then have something that can take the 5V from multiple inputs and up scale it to charge a 12V lead acid battery (or a bank of them). The 12V battery can then drive an inverter to provide mains power.
So far I own a 12V inverter and that's about it.
Aha yes I mistook it for a resistor, still very nice and small.There is used a coil as can be seen in the application figure below.

Re: AA accumulator for your microchip
Hi Ben
I have a 1500W item that has auto restart (this puts the output on when the input within limits) some you have to go to the unit and press output on button.
Then then feeds a pair of contactors with a bit of wiring and interlocks to swap over the supply the invertor has priority , this then feeds the input to a ups the output of the ups feeds my home server .
this may seam a bit of an odd way of doing things but the G59 and synchronising Invertors where £££££
to be honest I am disappointed with the PV array performance, I have found some better units but they are too expensive and the size and weight of them is restrictive
have an idea of linking the dc input to the invertor from wind & solar to get the best of it but the wind turbines for 1000W are about a £1 per watt ... for the quite ones (<80db)
you could use it to charge a battery and detect when the battery fully charged then use the battery to power the item via the invertor ..
LTC do some solar power supply ic's
