Ok, so here's the deal.

I have one of these:


Your standard issue Aperture Science Handheld Portal Device, specifically one of the Cooperative Testing Initiative models.

It's awesome as hell, but I think it would make a kickass lamp, hanging on the wall next to my talking Cave Johnson portrait.

Anyhow, I figured it should be a simple enough matter, right? Get a 4.5 volt AC adapter and some alligator clips. The battery box slides out leaving a pair of springs as connectors. Clip the leads to the springs, plug in, viola!

Except when I asked the guy at radio shack about what milliamperage I should get for the adapter he informed me that there's no safe way to do what I planned because it guns on C-cell batteries and c-cells don;t have a proper amperage and if I tried it I;d blow out the LEDs

So I'm hoping someone here knows enough about low-voltage electronics to help me out. I want a portal gun lamp!

Plug it into the cigarette lighter socket and swich off the traction contol and you should be fine as long as you are running standard tires :)

I'm worried about blowing them out though.
If I don;t get the right amperage I could end up overloading them

Electronic parts parts dont draw extra power just 'cuz it's available. As long as the adapter has enough output, it will do fine.

Radioshack use to be a place of knowledgeable people when I was growing up. Today, for the most part, they are just sales associates working a job. I never trust the opinions I get from them any more.

Which is why I come here. I figure if anyone knows about jury rigging LEDs to do things god had not intended, it would be you guys :p

Got it working! Added a potentiometer just to make sure there was no chance of overload. Bonus: Works as a dimmer
