Hi folks, if your near Orlando Florida act quickly https://www.ebay.com/itm/282922837314?ul_noapp=true happy bidding, dave

Hello folks, I thought this patent had a humorous title. I like the simpleness of it, any open cavity folks here ? Piezo's disk cost pennies and you can use high voltage(+- 150) @zero current to make them bend your mirror mounts etc.. Also, anyone know the U-Tube, Tech Ingredients man? I have...

My Mom says told me she saw a saucer on the golf course one morning.  ;D I've seen electronics do wierd stuff many times. I won't go into detail. Something like this example does'nt count to the poll: Once I hooked up a CB antenna to the gutter of my buddys house and I got a continous...

I blasted the plastic pumpkin next door with 150mW from my DX labby (I got a champ) and that thing lit up beond my expectations! That's fluorescent transformation. COOL Happy Halloween to all globalist. Good way to make a Great Pumpkin. (Linus of Charlie Brown comes to mind) ;D

Bottom line: U need to buy Cyber Ultra DVD or WINDVD Blue Ray software for about $90 (search for coupon codes or best deal) then U got have a PCI-E :Geforce 8400 & up ... or ATI HD 2400 & up, cus it has decryption crap. Corell's WinDVD will work with less powerfull vid cards. It does the...

The Texas Petawatt laser reached greater than one petawatt of laser power on Monday morning, March 31, making it the highest powered laser in the world, Todd Ditmire, a physicist at The University of Texas at Austin, said. The Texas Petawatt is the only operating petawatt laser in the United...

350$ new in 1980

Check this out. 70mw supersmall using 1 watt and can pulse down to  fractions of nano seconds( billionths ). I'd like to see specs on the blue laser they said is readily available! Can't wait to see tiny color laser projectors, I love HD video! Dave [smiley=beer.gif]...

The siesmographs are going crazy with activity here in St Louis, Mo area and I think we are due a a great earthquake that has been forcast ! New Madrid fault line. Please! everybody think about this; and wish for peace for us here. I believe in mind over matter. Because the more people that...

ColdShadow, Haven't bee on in 5 days so I desided to veiw my last 25 post to see if there was responce. I got a "no post by Laserrod" returned! :'( Bug?

Did you know Mexico means bellybutton?

Meaning of new class/structure according to your number of post. I just saw hazard ratings for laser power stickers: 1 = no risk 1M = low risk 2 = Dazzle hazzard 2M = don't focus with optics to eye 3R = 1-5mW 3B = 5-500 mW 4 = greater than .5W Now I know why the member level/class...

I've wrote earlier that I want MosFet regulation. It's about the most efficient /simple liner current regulator because of less battery-space and waste heat hassles. The circuit waste only about .5v!  with voltage determined by the type and ambient temperature on the NPN transistor. Parts...

Let's all input power data and see what proformance averages out to be! Every greeny owner ,Please give us: 1. Make and model and makers claimed power output. 2. Power output you measured or if you have no power meter state what you think it is by comparison or other means,. 3. Measured...

My DX 30W laser draws .3 amp., my Nova X 30mW, .5 amp.. Hemlock Mike wrote .3 amp is max for the 30 mW DX. This makes the Nova laser seem power wastefull(Waste more power than the DX). My Nova is always brighter than my DX. I would like all experts to answer these questions: 1. Is the DX...

I thing your forum is HD! I'd like to know if you know a person who had a HeNe laser scanner, (light show) before 1974 March? I 'd like to brag about this, because I got to lite a cig. in my physics class to show a 2 motor mirror scanner beam path. NO SMOKING ALLOWED IN SCHOOL! I went from...
