Lazy layout request - integrating circuits with different voltages.
« on: April 16, 2011, 12:32:34 PM »
Hey,
got 2 potential add-ons for my casio sa-1 but both differ in voltage.

The first is a black blob board from a little voice-changer toy at 12v. The other is an uglyface I copied from a layout last weekend at 9v.

I'm only looking to integrate one of the circuits and wondered if anyone has a layout or suggestions for how I might do it or if I can even. As I've mentioned elsewhere my electronics knowledge is absolutely minimal so as dumbbed down as you can manage would probably help :P

Ooooold reply now... but yes :P

From what I can gather despite differing voltages there may be points in circuits that provide the correct voltage?

A 12v voice changer? I thought they all took a PP3 9v battery. Wouldn't you need 8 AA batteries for 12v otherwise?

How much does an SA1 run on in theory?

it probably says 7.5v on the case, but a Casio SA-1 would have an AN8053 poweramp chip.
ABSOLUTE MAX voltage for that is 11.5v, normal operation anywhere between 6 and 11v.

technically, 12V would be a no-go, unless you want to fry the SA1 in the long run.
so.. how does the voice changer sound on 9V?
