I will again when testing the new build, but yes, 5V per div on the scope shows clean flat +-15 and +5. The new one shown here is almost ready for testing anyway.

no it not legal. I also question the products longevity lacking tons of cooling.. scanning likely going to be crap at the low currents/voltages.

Have you checked your supply voltages?

any luck on finding the paperwork?

Thanks Steve; I have located a suitable crystal that is damaged, but has plenty of undamaged material to be able to cut 1, or possibly 2, crystals. Now all I have to do is locate a local person who has lapidary skills! I found a club, but it's at the opposite end of the country from me.

I've replaced all the semiconductors including the transistor and the diode, and the problem persists. The only thing that seems possible is a breadboard connection failure that survives spraying and re-seating, as unlikely as that seems. so I'll be converting the parts seen in the tray into a...

A4?…....................

Progress has been delayed by a problem that has appeared in the previously working SPGN circuit. I can't figure out why the "spiral out rate" control voltage input no longer has an effect on the fall time of the ramp signal that it is supposed to control. The "spiral in rate" and the fine adjust...

Find your local lapidary club. A friend who does lapidary slab sawed some Yellow ND:YAG for me. Cost was 25$ for the rough rectangular stone. Buy a surplus rod of the right length, Let the factory x-ray orient , polish and coat it the cavity facing sides. Sawing it down and polishing the...

I got the ClubMAX with Saturn scanners, however I still do not have a light show variance. I tried applying a few times from Pangolin's web variance application, but they seem to be ignoring me after the sale. I will keep pestering them. I have some questions about general setup, if anyone...

So after much chasing around, I managed to get a copy of the software that is supposed to work with this unit, however it kept reporting that the laser was an unknown type After a lot of investigating, including having to replace a NiMH backup battery on one of the boards and reinstating the tracks...

I have a hard copy of Craig Nelson's paperwork for the DRV series board. I will try to find it. Steve

Take home a spare pair of galvos and amps that exactly match what is in your new projectors. Overscan kills Galvos because the Chinese set up everything as wide as possible, for them that is a feature, not a bug, for most users, the ability to drive the scanners to the mechanical stops or to hit...

Nice! looks interesting!

NO, if any-thing needed to be added back in, Pangolin did it already. Main board change in that mod was the threshold for the limiting diodes was lowered by switching to Schottky diodes from the existing Silicon and the gain on the position demodulator was changed. If Bill Benner tuned them, then...

There's definitely something there. Memories from a simpler time. ____________________ Marius from Artys Transit

I think my direct quote was "...like smashing you in the face with a brick for an hour", and I saw many laser shows by other companies (who shall remain nameless) where I left exhausted with my ears ringing. Laserium was all about PACING. Yes, you should have those high energy numbers - they're...

I think it would be a mistake to try to define Ivan space as devoid of the music that it interprets. And not just any music. There may be a real connection between Laserium's early success and the best of the progressive rock experiments that were happening at the same time. I see clips today and...

Here's photos of a color mapping experiment in which an HSV grid is mapped to cycloids. The desert scene is a scrolling background that resembles a blocky old VIC-20 game. The code that generates the color map has access to the same live and recorded input as the rest of the system so one can set...

Looks wikid, ive loved developing software around your standard Helios controller. Take care

Likewise. Seem to be by far the easiest option. ___________ Marius NDR Lighting
