Attached is not even a beginning... I'm away from my laptop tonight. That second attached drawing is a PID amp without some modern analog functions that make high speed raster scans possible. . Modern amps are variable PID or PII, and can switch modes, and have spaces for notch filter...

One warning, hooking a tunable signal generator to the amplifier input without a bit of education is very fatal as scan angle and frequency increases. Most modern makers of cloned galvos have omitted the coil protection calculator circuit. There are definate frequency vs angle response transfer...

Dear Steve, Thank you so much. I really appreciate. i am very happy to have it and got to work with my laser.

I know what they mean. I have the third or fourth largest collection of galvo documents in the user world and know where the patents and journal articles are,. Issue is achieving Automatic Gain Control for the feedback sensor and some circuits which achieve linearity correction. The Galvo...

Ok, it made the journey from storage area to my car. I'll borrow a document scanner tonight. Steve

I think you mean "ex-friend" ;)

Thanks so much, all good info! As it turns out the OPT PR8000-RGB is too small to fit the DT 50 electronics and mirrors in. They say they use the DT 50s in 20w and higher lasers. So... makes the decision easy ha ha, I'm going with the DT 40s. Should be here mid April, we'll see how it looks. ...

Hank, I think you are my "oldest" friend. *retardo

Hi everyone! I realize that the last post on this thread was 18 years ago. I too am trying to find the adult ILDA graphics. A friend of mine had them before hurricane Katrina in 2005. If anyone could point me in the right direction or possibly have them, let me know! Thanks!

I'll take that Senior Discount! 😉

For the blue version of this laser, 6 flashes is head read error... I might have the 85-YCA manual on a different computer, will check. Do you have a different cable you can try?

Those may still be supported by a company in Rochester New York that brought the remains of Melles and did the MBA split thing. Try at IDEX Health and Science. You'll have to call for tech support., you won't find it on the website. Steve

Update March 30, 2025: Sold.

Who are you calling “old”?

I'll be there. Plan to bring my VR rig again as well as my DJI FPV. If possible I would like to attempt some FPV racing in the field next to the venue. Can't wait to see my old friends!!

HOLY this thread is amazing! I did not even think to use half this stuff for laser effects. Now off to thrift stores with the laser pointer and another project to build.

I have a set of DT50s. Solid performers. Things may have changed since I bought mine but I don't believe the DT50s come with a power supply. That being said, be sure to use a beefy PSU as they are a little power hungry and you need a PSU that can handle the current spikes needed for...

No. Adulting is over rated. And yeah, I guess I’ll come.

Oh hey, I'll go. Shirt size XL

I must have felt the call of the signup page appearing! I stayed at the Homewood Suites last time (I think) 😉 Next door to where more people stayed. I will be getting a room with two queen-sized beds .. so looking for a roommate to share costs. I will be renting a car for transport to/from the...

Thanks Steve. I appreciate. Your help will be very useful for my lab. Mbhomi

I'll scan it in. Take a day or two. Steve

So I was unboxing this random box that arrived and had a very chill experience. A Hybrid 98 type of Chill. THANKS MATT...:cool::cool::cool::cool::cool::cool::cool::cool::cool::cool::cool::cool::cool::cool::cool::cool:;););););););););););););););););) Steve
