So I just put together the MintyBoost basically using the stock configuration. Seems to work great, but it seems like it takes much longer for my iPod Mini to charge when using it. My Nintendo DS seems to work, but sometimes it looks like it refuses to charge off the Boost. I'm wondering if the current draw might be too low?
For instance, when I plug in Minty Boost, my iPod shows that it has power connected to it, but when I start using it, the batter meter starts animating like it is charging the battery. This doesn't happen if the battery is fully charged and it is plugged into using my wall adapter.
I read on the site that Minty Boost outputs 100ma by default, but that you can jump it up to 500ma by changing the resistors? I was a bit confused about what exactly I need to do?
Also, I was thinking of actually putting Minty Boost in an Altoids Mint tin to try and see if I can put 3 batteries in instead of 2 (since I will be using rechargeable and the site says that 3 can help extend the charge?
Thanks for the help!
Current Pull Too Low?

Re: Current Pull Too Low?
not sure, i would check the voltage output. there's no 'too low current draw' in this case.m00dawg wrote:So I just put together the MintyBoost basically using the stock configuration.

sure you may be using more power than the mintyboost can provideFor instance, when I plug in Minty Boost, my iPod shows that it has power connected to it, but when I start using it, the batter meter starts animating like it is charging the battery. This doesn't happen if the battery is fully charged and it is plugged into using my wall adapter.
make both resistors pullupsI read on the site that Minty Boost outputs 100ma by default, but that you can jump it up to 500ma by changing the resistors? I was a bit confused about what exactly I need to do?
it may...but if you want more total juice its eaiser to just go with C or D cell batteriesAlso, I was thinking of actually putting Minty Boost in an Altoids Mint tin to try and see if I can put 3 batteries in instead of 2 (since I will be using rechargeable and the site says that 3 can help extend the charge?

Come to find out, it works much better when you actually use GOOD batteries I was using old NiMH batteries and I guess they were not holding a proper charge which caused all the weirdness. After putting in newer and known good rechargeables, MintyBoost is working like a champ!
On a tangent, since you mentioned using C/D's, any idea what the runtimes are between them an using AA's? Seems like it would really increase the bulk and MintyBoost fits so nicely in my pocket, but I was curious just the same.

I've looked at the specs for some of the C & D NiMH rechargables and they don't have any higher mAh capacity than the AA cells. Thats likely not true for ALL brands, but just a heads up.
I have no idea if this is true for alkaline cells, or not. I've never seen published specs for the mAh capacity of alkaline cells.
