    Hi there! I've been working on a 3D rendering engine for video games that outputs a stream of samples to be displayed on an analog oscilloscope or similar CRT XY display. These types of displays are most similar to laser projectors. In fact, I suspect it would be very easy to control an...

    I don't like to post about pointers here but these lasers caught my eye. Curious how they're getting this wavelength on these pointers. I don't know the complexities of raman shifting but this does seem to be a viable raman shifted wavelength from DPSS. These are the only lasers on ebay that I...

    Free if anyone wants these old glass epoxy metrologic HeNe tubes, obviously not working. Also an AOM which worked last time I used it twenty years ago.

    Hello forum! I recently learned how to fix Verdi lasers, and once I had one working, I was captivated by the beauty of the SLM green light. I would like to fix some more Verdi lasers, to get to know them a little better. Really, just for the fun of it. If anyone has Verdi, Chameleon, or...

    @Photonlexicon used a nice solution that he shared with me. I thought I had posted this before (maybe I did but I couldn't find it so here it is again. I used this "inverse" of the slotted can solution with both G115 open-loop and G120PD closed-loop scanners. No question it worked best with the...

    The Mark IV & Mark VI projectors used a big old non-feedback galvo that looked like a G330 for chopper. The Mark IV used the same galvo for scanners. The chopper was a slotted can. It was relatively slow with soft edges. If I was designing something today I'd make it capable of higher speeds and...

    The missing variable potentiometer could be most any value where its full resistance plus the 3.3K Rin to the 2nd op amp and it's .22uF feedback resistor makes up an integrator that generates a triangle-like waveform. The triangle wave is feedback to the positive input of the first op amp thereby...

    I don't. That is part of what I'm posing as a question to the community. I have been using the ramp generator which I sent you, also called the colormod2 circuit, for both chopper and colormod effects. When needed, I also use the PDM signal from the spiral board for retrace blanking. For more...
