Did you guys see this? http://inhabitat.com/19-year-old-teenager-makes-homemade-solar-death-ray/ I find the footnote at the end of the article hilarious!

Link dead?

Re: Modwerx ripped me off... HMike, you still do it? I was hoping it was something one grows out of. Just saw this movie - what a classic line: YouTube - Despicable Me - Vektor - "Oh Poop"

A friend of mine always says once you let the smoke out, they're no good anymore! As to negative resistances, you can get that with quantum well states. As you line up a well the device starts to conduct, but as the state becomes too high, then it stops conducting until the next well lines up...

+1. Don't save a few bucks by gaining a blind spot. All it takes is one stray reflection.

I was looking through our lab and found what looks to be a really nice diode driver/TEC controller. I don't have a manual for it, though. Looking online I found that the company was bought-out in '97, and the company that bought them doesn't have any documents on them. I'm hoping that...

Great deal Bob. Let us know how it goes. You're going to dissect it, right? K

Yeah, just don't turn it the wrong way... K

I thought the current limit was from the temperature? Do you monitor the temperature?

I wonder what the freight would be to the midwest? $200-300?

I've bought from them w/o problem. Dave is the one who mentioned them to me. Perhaps Dave will comment?

Don't know exactly what this is, but it has a lot of optics/motors that might be useful to someone here, and you can not beat the price: SHARP LASER ASSEMBLY - Surplus Shed Kristopher

Lots actually. What you want is a laser module: A laser diode with a driver in a case with a focusing lens. Lots of people in the BST sell them. Ask for pig tales (means bare wire leads) or some come with 9V battery clips. Then, instead of using batteries (as for a pointer), wire the leads to...

Hey all, I would like to buy some 405nm modules. Modules to me have a Aizix housing, diode and driver. I don't really care about how many mW, as long as it is stable. Pigtale leads would be ideal. I purchased a few back from Blueray before everything happened to him. I've also purchased...

Charlie, Put me down for 4. I sent you a PM, but I think my account is screwed up or something. See if you get the PM. I ccd myself, and I got a copy, so I know it sent. K

Charlie, Did you get my PM? I am interested in modules with drivers. Check your PM for details. K

Heat!  Duh! :)

Any luck finding that Schematic GooeyGus? K

Thanks for the many inputs. I look forward to the details on how to bypass the starter. I just realized I completely high-jacked this thread - sorry to the original poster.

Herein lies the problem.  When the unit is turned on, a plasma discharge is evident.  It isn't lasing (UV checked).  The He heater is disconnected, too.  After about one minute, the plasma stops.  Then, after about five minutes the plasma will ignite, but only for about 30 seconds. After a few...
