The other day I noticed that the head of an Aixiz module (or in my case, the DX cheapo knockoff (http://www.dealextreme.com/details.dx/sku.5914)) fits nicely into this "Super Mini Vintage Oil Lighter" (http://www.dealextreme.com/details.dx/sku.3734) with enough room to clear the lid.
I immediately envisioned a tiny keychain burner of some sort... Figuring I could fit 3 or 4 cr1025 3v lithium button cells in there, and if I could point-to-point solder some smt components into a tiny driver, I should be able to do it...
A couple things have occurred to me as potential problems... one being how the hell am I going to mount a button in this thing... and secondly, I have no real experience building burning lasers before so I don't know if the head of the module will provide enough heatsinking... I'll probably have to insulate it from the case since I'm thinking of a screw-in-to-turn-on type of switch... I'm obviously not going to need continuous duty from this thing, probably going to be using it for a max of 20 seconds at a time. Can anyone tell me if that will be enough to prevent catastrophic thermal failure?
Any input on whether I'm crazy or not?
