What to do with 40 of these things?

[JZatopa]

I just got my hands on 40 of these PSP power supplies/chargers

now the question is what the hell should I do with them?

Should I try to put 10 in series to give me +/- 25V?

Any worthwhile projects that only use 5V?

DACs, attenuator chips, LEDs, Swedish-made penis enlarger pumps, etc.

do you have a schematic for a Swedish-made penis enlarger pumps that uses 40 of these?

I bet this guy has gotten a lot of ideas, you could ask him.

Sell them on ebay?

Might be handy for small projects,where 5V is needed.
Routers,Modems,etc. that you've lost the original adapter for.
Add some USB sockets to the end of one,and you can charge 3-4 phones (or other USB devices) at once.

Do they in fact tolerate stacking?

I haven't tested yet.

Most are fine with stacking. Perfect raw heater supply to feed a 6.3V regulator.

I'd try a low cost power amp, say LM3886 (5$ each IC). Just need some resistors and scanvenged whatever-value capacitors.

For a +/-35v psu, put 7 of them in series for each rail providind +/-2 amps, enough for a stereo setup. PSU will take up some space, but, anyway, it will still be lighter weightwise than a toroidal trafo.

So i opened one up to check it out and here is what I found.

The SMPS chip is an ice3a1065L which looks like an interesting little chip.

The other chip is an optoisolator NEC 2561A.

at a minimum I could scavenge the 400V 27uF caps and the OKAYA LE104 275V .1uF cap.

Perfect supply for an overclocked Raspberry Pi. DIY AirPlay speaker or a small player running RaspiFy via a Hifimediy Sabre DAC? EDIT: or an ODAC? 😉
