Trajork: Find an IR LED that actually spec's it's output, bandwidth wise, and see how much of it you see. I have a pile of IR equipment, including 1W 850nm illuminators. They appear a "dull red" - until you actually put an 850nm peak filter on them and then... nothing. Don't be surprised that...

Of course! I should have thought of that. I'll let you know what happens! Thanks! Mu

Just don't add "get really drunk and..." to the front of that. I'm surprised that you use a torch instead of plugging them onto the AC power :eg:

Oh man. I have been trying, unsuccessfully, to get the damned retaining ring out of the Training lens assembly of my late model G1. Scraped out all the glue. Tried c-clip pliers, needle nose pliers, put acetone on the threads to try and dissolve any glue I can't see. That sucker is just frozen...

I'm sorry, but what does ZVS stand for? Looks like a CRT flyback design... NST I've got, but the Z has me stumped.

They should open it up as a tourist attraction. It's right outside Moscow.

Portable Jacob's Ladder I love the whole TeslaPunk look of that thing. Nice! PS- Check this place out... http://www.darkroastedblend.com/2007/07/creepy-high-voltage-installations.html

I am SO giving up on making jokes... In one day I bombed with the pink thing and "muzzle-loading plasma rifles". Some things just don't come through in ASCII! Muuuuuuuuuuuu....

Assuming you have an ATX power supply, here's the pin-out. If it doesn't turn on, connect pin 16 to ground. Older PC power supplies don't have these control signals. ATX - Wikipedia, the free encyclopedia Let us know what you find to work with.

...Looking for pink on spectral chart...

Red & Black But the output may not be 5V without a sizable load on it. Most switching supplies require a minimum load. If you have a DC wall wart power supply that is above 5V, you could do a ~1K resistor -> 5V zener + Capacitor as your ref voltage. Does that Analog version turn on if nothing...

Or are lasers a strictly guy thing?

Spark gaps (like ladders) are broadband RF emitters with much of the low frequency being conducted into the power line. If you create a ladder with an old style neon or oil-burner ignition transformer, the hunk o iron limits the HF conducted. Find a Corcom filter, ground it well, and hook it...

They have a slower response time and a larger gap between the standoff and breakdown voltage. They generally don't spec the range of the breakdown voltage for any given part. Whereas, the TVS's might say 5.8min,6.0nom,6.2max in the spec. This gives the designer a much better idea as to how...

I was attempting to be humorous by taking it to an extreme. How about laser sight on slingshot? Never mind.

Hah! Kind of like a muzzle-loading plasma rifle ;)

I like the idea of a "safe space" for charging Lithium batteries. The part I'm not cool with is the instructions telling folks to stick the cells and, in most cases, the charger into the bag and zip it up. This would tend to trap the heat from the battery and charger and increase the chances...

SCP-512 - Firefield Green Laser with Barrel and Weaver Mounts External Adjustments 100 Yard Visibility SCP-275 - Firefield Green 5mW Laser Range 100 Yards Tail Cap Switch and Rail Mount Start with those?

Blech! I was afraid of that. I found a reference to a German(?) company that WAS going to sell a small diode pumped CW laser but now it points to a dead end on their website. Thanks for your help! Mu PS- I did find this... GemologyOnline.com :: View topic - more ruby comparison

Instead of flashlamp pumping a ruby rod laser, what about diode pumping? Does anyone know what pump frequency a 694.3 nm ruby rod likes best?
