[sdiy] Wallwart questionne

[Peter Grenader]

Guys,

Question:

I'm building somethin' for someone that runs off of 12  and 5 volts and his
PSU system is +/-15.  He wants the thing compact and mobile.  First, I was
just going to regulate down to these voltages inside the little cabinet,
but....

Now he wants the option of connecting either his 15 volt PSU -or- a wallwart
to power thjis little bug.

I'm not sure this can be done due to the circuitry required for the
wallwart.

Can it?

Anyone?

Anyone?

thanks in advance,

P
