Make picooz micro heli controller run from ac/dc adator
I want to mod all my micro heli transmitter/chargers to run of a 9V dc power adaptor, I'm tired of changing/charging batteries for them and seen as I sit next to a power socket when I fly this is the best option.
For this question I am focusing on the picooz sidewinder remote.
What I have planned is to use a dc barrel or 3.5mm jack socket, connect - to the battery - on the pcb
and connect the tip to +in on the pcb the switched tip to the battery so that when nothing is plugged in it automatically runs from battery.
what I would like to know is...
where to add a capacitor and what rating,
this to provide enough power for the fraction of a second when the plug is pulled out, without this I would have to "trim" the controller each time because it would turn off for that small amount of time and forgotten where it has been trimmed to.
thanks in advance.
ps once I have this working I will be doing a full Instructable on this subject.
