    HeNe testing advice

    So I don't have a proper driver for my HeNe tube at the moment, I picked it up for $5 or $10 at a swap meet a few years back. So I hooked it up to a micro fluorescent tube driver from an old office scanner to see if it would do anything. I know it's terribly under voltage, just testing to see if...

    feeler: LN2 dewer

    Well its a 4 liter dewer. I havnt tested it yet, but it has a port to re evacuate the cylander if its low. My guess is somewhere between .4 to .6 liter per day depending on the vaccume... .6 if there isn't a good vaccume. I still need to go out to get some LN2 to test it. It'll probably be a...

    Mini-review 50mW Green module from Fasttech

    Well seeing that the 50mW are so much more powerfully it wouldn't supprise me if the 30 was actually 50. You could unscrew the module and insert an IR filter if your worried about it, but from the reports I've been given they're fairly low IR output.

    What's the scariest PC game you've ever played?

    Wolf3D is a good game, I like it... simpler times :) As for scarry, pretty sure theirs a minecraft mod for that ;) typically not considered a scarry game, but its a false sense of security. I've lostit a few times jumping out of my chair walking around a corner to find a creeper where I was...
