rechargables with cheap hasbro sound.

[AEwizard]

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 (http://forums.thecustomsabershop.com/showthread.php?t=9527)

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.

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

"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?:confused: Im new to electronics so please try and keep it simple.

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?:cool:

[AEwizard]

ok that helped a LOT. :o now i get it.

[Jordandau]

You could also try Nimh instead of L-ion, that would put you under 6V.

[cardcollector]

Or you could just use One Li-on Cell, saving space and not having to resistor your LED.

I would also like to thank you for "Stepping up" on these forums. You are communicating better, but still need to master the ways of search-fu. Only then will you become wise in the way of sabers...

[AEwizard]

I do need to get more search-fu.:) Thanks a lot.

in case it helps I drew up that very circuit last night
here you go, has recharge port, two li-ions, and a pcb

What do you think about this setup, with this you don´t have to use a regulator. Will that work or will I get any problems with heat? Actually I dont see the reason for using a voltage regulator? :confused: SEE ATTACHMENT --> (Or is 6V source to much for the cheap hasbro boards???)

[Rhyen Skytracker]

I am not sure where you will find a 6V rechargable batt pack. Most batteries are either 3.7V (Li-Ion) or 1.2V (NiMH) You can use 4 NiMH batteries for 4.8 Volts and not even need a voltage regulator. 4.8 Volts is very close to what the econo board is designed for anyway.

You are right, I thought AAA accus have 1.5v not 1.2 ... But what if I use 4 AAA alkaline they have 1.5 so 6v is that to much for a hasbroboard?

You are right, I thought AAA accus have 1.5v not 1.2 ... But what if I use 4 AAA alkaline they have 1.5 so 6v is that to much for a hasbroboard?not these new ones, no. they should run okay on 6 volts.
