rechargables with cheap hasbro sound.

Hmmmmm. I have a question. I was wondering what I would need to power the eco soundboards with rechargeable batteries in the hilt. I've been reading up on this stuff and cant find anything useful. I need to know what the max voltage is for the card. So i have to right rechargeable batteries.

Three minutes of searching, maybe you should read This Thread

[AEwizard]

oh i read that thread... It must have skipped my eyes sorry.

remember that the LED Middle and right Legs are switched!

I take it that -within reason- you can use any voltage pack you want, because of the 5v regulator?

[cardcollector]

Yes, but I would only use it if I was using a 7.2VLi-ion setup.

Exactly... "within reason" meaning 6v or up to 7.2v would be ok.

However, keep in mind people: when you use a standard/basic voltage regulator... all it does is shunt off the excess voltage as heat/wasted energy. In addition to the waste, this also means that you MAY need/want to heatsink your regulator(!)... because just spitting aside upwards of 3v is not exactly easy to do. A regulator will get *HOT* if you are having it shunt off anything more than 1v.

My recommendation is to avoid regulators as much as possible, and simply follow the advice of 'The LED Bard': "Suit the project to the battery solution, battery solution to the project."

Advice taken

hmmm what do you mean. On the PNP transistor? I dont get it? Im new to electronics so please try and keep it simple.

[cardcollector]

OK, you want your LED board Negative going to the Base on PNP
The Battery Positive needs to go to the Emmitter PNP
The LED positive to the collector on the PNP

Does that answer your question?
