    I understand. For those who publish shows on forums/youtube/facebook, it makes sense to have the highest quality to add validity to a new product. For my living room laser show, that's the equivalent of using a Ferrari to pick up the groceries! My projectors are all single-mode 250mW...

    Nice work, PJ! I'm plugging away at it, I swear! :) I think I'm a week away from completing this two Saturn build. Things are obviously a bit messy at the current state. For those of you that I haven't told, this build is essentially half of this 4 Saturn single-mode build. So that's...

    A harmonograph is a physical machine. There are variations on the idea, but the classic design is modeled in math simulations using four pendulums. A pendulum does indeed swing in sinusoidal motion, but it takes two sin functions to emulate the fact that it can swing in ellipses (not just one...

    Completely agree. Soap and water is far superior to hand sanitizer! Although there are situations where hand sanitizer is the only option, as soon as you get to a place where you can wash with soap and water, you should always do that even if you used hand sanitizer previously. (And remember to...

    I'm going to take a stab at this. Maybe I'm missing something, but this seems like it's a solved problem? Yup - agreed. But all pendulums follow sinusoidal motion with decaying amplitude. (A pendulum is pretty much the definitive example of sinusoidal motion, at least in classical...

    buffo replied to a thread Galvo/Amp Upgrade in Modifications
    Thanks to Andrew for re-drawing the schematic. :) Also, he correctly pointed out that interrupting the ground connection on the modulation input won't work because of the shared ground on the power input side. I had forgotten about that! But yeah, the correct method is to interrupt the positive...

    buffo replied to a thread Hello All, Laser Question/Help in Help!
    I agree with David - there's not much harm you can do to the 506 scanners because the amps will shut down if you do something incredibly stupid, and if you're just doing something marginally stupid the scanners themselves will simply grin and bear it, albeit with a degraded image. :) ...

    Yep, I know what you mean. For beam shows, the separation is almost invisible but for graphics, the trick is to just "hide it", by never doing anything that has red alone. I'm interested to see David Kumpula's assembly since he combines using dichroic rather than strictly edge combining as your...

    Glad the operation went well and you learned some new skills. Well, first you shouldn't be projecting at a rate faster than the scanners are tuned for. I assume your scanners were tuned for 30kpps as they appear to have 5mm mirrors. I'm sure Pangolin included a sheet in your package that...

    I so wanna fix it with a new module but that's a matter of waiting and time. For now ill settle for it and be careful with my use of reds with this laser module :desire: I really think beam brush made this so much more organic and filling and this was just an 8 hour job. Working on much more in...

The scannermax scanners are 1000 times better than the original scanners in the laser. Thanks for all who have helped this novice hobbyist along through the process and...

    Interesting. When I printed in vase mode, it was clear. In fact, I have made fiber optic with it (lossy but still carried light).

    Hey Ron, I think I remember using the keypad, but I could be wrong. I agree the ADIG was a dog. (Sorry...) (Greg, the ADIG was in a 2U bud box under the hybrid card cage in the control console.) Originally the entire board (yes S100) had +5/gnd dasychained to every chip from a single point. I...

    I used that in a prusa. Comes out milky. Could not clear it. The only printer I could clear was formlabs liquid printer. THAT is sticky mess.

    Thanks for the long lasting chuckle, Ron. The Flying Spaghetti Monster is my go to deity on the occasions that Tolkein doesn't serve up a contextually appropriate Ainur.

    On Facebook, PJ posted his work perhaps 3 weeks ago, and Mike Dunn's more recently. I figured some people here on PL might not have seen them, so I'd re-post them here. Yes indeed. So far you've only seen a few of these released, because some were submitted for ILDA Awards, and people...
