Mintyboost not charging

by **Aaron** » Tue Jun 06, 2006 3:28 pm

I received the Mintyboost a few days ago and assembled it in an hour. Its a great design, but for some reason mine won't charge anything.

Everything is reading correctly on my multimeter (3v on the batteries, 5v on the USB) so this is really dumbfounding me at the moment. I've tried an iPod with video, a Blackberry, and an iPod shuffle and nothing is working, this is frustrating. There is so far one glimmer of hope though, when I plug the Blackberry in, the charge symbol comes on for 3 seconds, and goes off. This is all very strange.

try putting in the 10K resistor (or short) as detailed in http://www.ladyada.net/make/mintyboost/ ... .sometimes certain devices dislike 'bare' battery packs

Thanks for the quick reply,

I tried the resistor, still no go. Neither of the devices "see" the Mintyboost as a power source.

Not sure what else to do.

Update:

If I reset my iPod with video after plugging it into the Mintyboost, it begins to charge.

If I then disconnect and reconnect, it will not charge.

I went to the make.html...sometimes link, but it appeared as a bunch of unloaded images and no links and the only text are "Research", "Make", etc...

the ...etc is not supposed to be part of the link

Our ipod video (30gig black) wouldn't charge with or without the 10k hack. It did run the batteries down but didn't see it as power. When I tried the reset trick it saw the mintyboost but we're not sure if it actually charged. My ipod mini (1stgen blue) lies that it's charging but doesn't with or without the 10k.

We're doing our own round of tests and expirements with the mintyboost and with a apple usb power adapter.

I'll post anything we come up with.

Yep, I not able to charge anything either. Tried both a Blackberry and a RAZR. As someone else mentioned, the Blackberry showed that it was charging for about 3 seconds, then nothing. Also tried the hacks with both of them. No luck. Nuts. Now what? :cry:

did you try the most recently updated hack? (with the 2 resistors)
it could very well be the blackberry and RAZR require a more complex circuit...

i sort of doubt that its lying...ive tested multiple mini's and they always work.

regardless, try the new hack i put up yesterday.
