    Check out Taulman T-glass. I have been considering using this. https://www.matterhackers.com/store/l/taulman-clear-t-glase-3mm/sk/M0JPUF5F?rcode=PPCADS&gclid=Cj0KCQjwgJv4BRCrARIsAB17JI5nK2GULtqGKjwr0H9q8D1nGeiv5YMdgZ-5IpZe7Vh24xRxZd3Ko-gaAjQHEALw_wcB

    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...

    Brian, To my knowledge, the ADIG keypad was never implemented. At least mine was never used for anything. Just a waste of panel space. And speaking of a waste, in my opinion, the ADIG was one of the singular worst pieces of equipment ever installed by Laser Images. Definitely the most unreliable...

    There weren't enough 351 bits available for all the different Dog stuff, so there were three switches added to the remote panel - two switches to select between 4 posibilities and one switch that inverted y axis output. The 352 card was introduced to distill the 3 - 351 decoder boards down to one...

    I have only used it for plexi and no it doesn't soak in. It is also just a quick shot at the surface. not a 20 min soak. frankly I do better by hand.

    ... does the solvent not soak into the material? When "vapor-polishing" ABS with Acetone you have to temper and vent it for some weeks, until it's "original" ABS again :confused: Viktor

    For lasers the cheap stuff is fine for a single wavelength. Well so long as it handles the power level and has basic quality like most optics today. A glued doublet might actually be an issue.

    There was blood! I really stink at it. No patience. I have optical clear resin from form labs. Works well but you have to spend a lot of time polishing. I'd rather cnc plexi and then spend the time polishing that if forced.

    No, this will only work if the input terminals are isolated from the power supply, which is not going to be the case with virtually any laser driver. The positive modulation lines are still referenced to the system ground, which your diode drivers are still going to be connected to via the power...

    Sorry for the double reply, but two more quick questions. In the drawing I did above. Can you tell from the looks of it if the RGB two pin laser connectors look as if they would plug into their respective ILDA pins? It looks as though they do but I just want to be safe? Second question, would I...

    First of all, thank you all for the replies! I am reuploading the schematic, not sure what revising I need to do to omit the remote interlock box. I took electronics is highschool but I am far from perfect, but does this looks like what I would need to omit? Would I need to keep the diode and...

    This is an excellent demo of the Beam Brush effect! Thanks for posting this, Bill. I've seen some of the early work done by others, and PJ has also put together a few examples more recently that show what could be done with Beam Brush, but this abstract example by Mike is the one that really...

    I bought a polygon scanner off E-bay almost 20 years ago for like $30 just to play with. It was a pull from a grocery-store checkout scanner. I think it had 10 mirror facets, and each one was about an inch tall by maybe an inch and a quarter wide. Never did check the RPM, but it was fast! Nice...

    Pretty much what I figured. I've been using lenses from Thorlabs which seem pretty nice for the price. Maybe I'll get one (expensive) asphere to experiment with.

    That's what I was thinking... It's not that an achromatic lens offers any benefit over a standard aspheric lens when the beam is monochromatic, it's just that as a general rule achromatic lenses tend to be manufactured to higher tolerances than the cheaper, non achromatic aspheric lenses. ...
