so im building the minty boost project here: (1st schematic on the page)
http://www.ladyada.net/make/mintyboost/parts.html
i want to put it in a project box with rechargeable battery pack and a jack to charge it from a wall wart. the IC has a max volt input of 5v. for batteries i have 12 duracell NiMH AA 2650mAH. not sure if i should go for 4.8v@7.95AH or 3.6v@10.6AH. the watt hours are the same. the trickle charging circuit im thinking of using is here(circuit #3): http://talkingelectronics.com/projects/ChargingNiMH/ChargingNiMH.html
i included a hand drawing of what im thinking. i would like to hear feedback if this will work or if i need to change anything. i do need some help finding the correct voltage and amperage for the wall wart to use as well as resistor values to use in the trickle charger.
