'suppose you're thinkin' about a plate o' shrimp.' Think again! Perhaps you should invest in a Geiger counter.*nyancat

Thank You. Steve

It’s was great seeing everyone at SELEM this year, sorry I could only attend for 2 days but I had a blast! I wanted to share a pic I took of one of the posters the band gave away, signed by the band and the laserists!

I have a copy of it. I’ll send you a PM.

Anyone have lazymameD2K.zip or the other versions of LazyMame for qM2000 OR MAYBE EVEN BEYOND? Asking for a friend. Steve

There is a adapter for Helios. https://bitlasers.com/openidn-network-adapter-for-the-helios-dac/ I have one on long term loan from a friend. Works Its a Rock Pi board, Steve

I was an intern at IBM working on their Mwave DSP modem team. For about a year my job was to dial up different BBS systems and see which ones we could connect to and which ones we had trouble with, so I listened to a lot of modems. After awhile I wrote a Visual BASIC program to do the work for...

I had this meeting on my calendar to attend but I got delayed while moving my daughter into college. Are there any available notes or can someone at least summarize any interesting discussions. The main thing I am really interested in is if this standard is dead on arrival or if there is any...

Ahhh the good old days..... Whhheeeee... Brrrr... Grrr..... Big Dong Dong ........grrrrr........ Bipp !!

You're actually getting a manufacturer's variance but the thing you're manufacturing is a show. It's weird and confusing but that's how they word it. No need for you to learn how to file or pay for a variance. Any reputable manufacturer is going to help you with that for your first purchase

Thank you for the clarification. I am trying to decipher the FDA Form 3147 - I will be back later with some specific questions in this thread. First question - the variance needed for purchase would be a "show" variance, not a "manufacturer" variance? EDIT: It looks like everything I need is...

Purely from a legal standpoint, yes you need a variance. Even if it's for home, non-commercial use, in the US buying a class 3B or class 4 system requires a variance for a legal purchase and a reputable company like Kvant won't sell a system without the purchaser getting a variance. For FAA, no...

Thanks laserist. Yep 3600RPM confirmed. 24 cogging positions are very subtle. This drive was probably from one of my Win3.0 systems long, long ago. The extra wires may be for Hall effect position sensors (or something similar) but there aren't enough wires for there to be the usual three...

Edit: I will also experiment with angle of incidence, too. It might be that I can reflect off the red with a different angle. I might give that a try before buy. I still wouldn't say no to suggestions though.

3600RPM probably 12v. The "steps" are probably what's called cogging

Update: these are sold!

All this panic over Windows 10 end of support when there's much bigger fish to fry- AOL is slated to end their dialup service in September. We're living in the last days...*retardo

The trick is to design a beam waist right at / near the mirrors. Easier said than done, but when you have good money its possible. Well corrected laser projectors seem to have a waist at or near the mirror pair and the best spot size/shape at about 35 feet / 10 meters. I try to run my well...

I recently purchased these Sparrow diode/lens/mount/TEC assemblies from Live LaserSystems in Austria They offer a wide variety of diodes, optics, mounts, and everything you might need for your DIY build. ! Tip: there's a hidden mouseover link located bottom center of every product box for more...
