Powering an "Suzie" O-Like Green Module w/5v Power Supply






um....no?

i've had modules die after around 15 minutes of total run time...
some thought it was because i was using a fully charged CR2 battery which outputs 4.25v. If your going to try this, expect it to die, that way your not disappointed when it does happen :)

hmm.. no I would not be happy with that. Unfortunetly I dont have time to build a voltage converter, I have found this circuit and I am wondering if it would work.

with R1=10k and R2=15K
 
just add 3 1N4001 diode in serie , voltage should drop by 1.5 Volt, this will be fine fr your module
you can find this diode in any junk electronic
 
hevnsnt, that's just a voltage divider network. It's useless if you want to draw current. Better use diodes like mauswiesel said (you don't have much control over the output voltage that way) or best, a step-down converter, e.g. the drlava FlexDrive.
 
hevnsnt;

Just find a resistor that drops the voltage enough to give you a little less current than you want.

Run it for a normal operating time and check the current draw at the end of that period.
Make sure it has not increased higher than you want to operate.

The regulators are the best bet but series diodes if you measure the applied voltage also are fine. A resistive voltage divider won't work unless you account for module draw current.
