dc-ac inverter alternative

[wsladaritz]

Got the plastic project box today, ordered the reg and caps, heatsink is on backorder, gonna check mouser tomorrow for that. Got the project box at radio shack. It is just a black plastic box, no perf board.... I didn't think to look on the wall and see if it is just a seperate item or something. I'll go back tomorrow.

Just want to check on some stuff before I go wiring and soldering when I get the stuff in. The input on the reg goes straight to the + battery? cap on input side goes to chassis ground? middle lead goes to chassis ground? cap on output goes to chassis ground? output goes to load (snes).

Now I was planning on cutting my existing power cord (I can get a new one ebay if I need to) and getting some kind of plug for a quick setup. Not planning on keeping it in their permanently. Just want a quick and easy setup for a trip without all the wires.

For the project box, some come with perf, some do not. They sell perf separately as well.

For the heat sink, any that fits a TO-220 package is fine. You should be able to grab one at radio shack.

Correct on the regulator wiring. Just note that the cap on the output side is polarized. It will have a stripe on one side, typically with (-). Make sure that the negative side goes to ground and the positive to the output leg.

When you cut the power cord, make sure to check polarity.
