Hey everyone! It's that time again where I need to part with one of my cherished treasures. This time it isn't going to leave such a gaping hole because I'm keeping my 594.1nm HeNe. Still, it has taken a lot to bring me to this decision. Anyway, the laser is in perfect condition, having been...

Hey everyone, thanks for looking. So, my tax return is coming in and I have about $350 to spend on my first non-cellphone camera since the film camera days. I'm a bit lost in the endless sea of cameras available and am looking for something specific; I want to be able to buy and attach add on...

Hey everyone, Thanks to c0ldshadow's recommendation on a good C++ IDE I was able to finish the project I was working on. I figure I might as well share it with you all. SigurthrEnterprises Blogspot - Wilson's Theorem

Hello fellow geeks! I'm starting to get really sick of VS2013 the more I use it. The whole project handling architecture, the fact that you can't bring up a second source file in a single instance of VS without having to save and close your primary file, the headache involved in trying to...

I picked up a cheap eBay "Cat Toy Laser" figuring it would be good for my cat, who is getting antsy as the weather gets cold and she can't be out chasing wildlife. I had given away my <5mW handhelds last year to kids in my family, figuring that I could always get more. I remember back before...

Just a lil something I've been up to. Brewster Tube Internal Sputter Cleanup Attempt - YouTube 7Lggr861I9c It didn't work, but was worth a shot. Got the tube for the cost of shipping.

So, with my recent BST thread sales and making a huge effort to save as much money as I can while selling whatever I don't need I've been able to set a bit of money aside. The money I've made has had to go to pay towards medical bills and debts, but it felt too defeating and self-sacrificial to...

Hey Everyone! Medical bills are piling up and I may be facing bankruptcy in the near future. As a result it's that time again... time to sell some wares! I have both lasers and non-laser stuff available. As always, I'm primarily focused on sales withthin the US, but depending on item...

I decided to work on an old pancake geiger counter I picked up a few years back. I did the circuitry repairs years ago but I never got around to making a computer interface for pulse counting/scaling. Today I rectified that. I'm posting it here because it may be of use for our members for other...

I had a hankering for some metal vapor photons, and it has been a few years since I've seen one of these beasts, so I thought I'd search YT for something to wet my whistle. This is one ***y lady of a laser. Copper Bromide Laser 11 Watt - YouTube M-R4Kq2l7xE

Hey everyone! I've recently begun work on a project I had the parts for for quite some time, but never got started on. I salvaged this XY stepper head from a cheap chinese "laser show" which had no programmable inputs and a nonfunctional "auto sound" mode that would only repeat the same three...

So, I'm in the market for a new gas laser and my heart is set on a yellow 594.1nm HeNe. Make me an offer, you need only compete with Sam Goldwasser's prices (LaserFAQ). For those interested I have a few things I'm willing to trade either in part or in full; -15W CO2 Laser w/ 110/220 PSU...

Hello everyone! In order to replenish my R&D budget for Electronics and Tesla Coil endeavors I have to let go of some things I just don't need and don't use any more. For sale is one 500ml flask type electrodeless discharge tube, filled with Xenon gas and trace Nitrogen/Oxygen. This tube was...

Hey everyone! I don't have any wood working tools, nor do I have the funds or space for any. I need small orders (in batches of 2) of simple 12" x 12" boards in a thickness between 1/2" and 1" (tolerance not critical, but must be under 12.125 inches per side). They MUST be straight unwarped...
