I thought that someone around here had a plant to go on, but there was a lack of board space
you could proly mount a board on the back of the gp32 case tho.... just need one more batttery
maybe a AAA???

the place is not a problem for me
it can be external, but it must not have bigger dimensions than the gp

How many volts does it have to be?

 

[washo]

5V I think

see you :lol:

the lowest usb should beable to work at is 4.5v so an extra AA batt + the 2 already in the GP should do it

Why isn't ingeras a Guru yet?

I don't know if you have accses to a radio shack but they sell a device that is a charger,adapter,and a portable power supply and goes up to 5v. Goes under the name of powerbank.

url ? pics ?

All you would need to do is add one more AA and tap off the batt wires in the gp32_console and find out which ones to attach it to to power the usb.

well that s not 5V


and for the radioshack i dont know if 4.5V is enough
but if it is, that s great
if someone can test ....

 

[Octavious]

hey gearhead
what type of time are talkin for a full recharge?
does it auto shut off the charger when done?

a very easy way that should work for most powered usb devices is to replace the power source with a 9v block.
ive done that here and it works like a charm.
first open you hub and look for the voltage converter, than google for the id to find out what the specs are, if youre lucky it works with 9v out oif the box, if not you just solder in another one, i used a 78T05

post some pics and a tutorial

thats so rudimatairy simple you realy dont need anything more i think (and i cant take pics, no cam at the momnt)

edit-> but you could open your hub and take a pic, than i show you where to look

the thing youre looking for most likely looks like

look whats printet on it and poste it here or look for it at google

So you couldn't just hook up some batteries to it? You gotta solder something in there? I have gotten a Handspring Visor (b&w one) working on batteries...along with some speakers If all you have to do is pop in batteries, what would be the best route? about 3-4 AA's? Some C/D's?

 

[thecheat]

maybe a 9v, small, but can you regulate i? i know nothing about this kind of stuff, im just throwing that out.
