    I used to like to set the 3 oscillators to variable pulse width rectangle waves with the shortest possible pulse. I'd calculate the freq of a nice low note in the 12 tone scale. I'd set one to that freq and the other two to an increment above and below that freq. Since it's a short pulse wave it is...

    I built a Sammich SID synthesizer, i'll have to dig out or take a video. I is fun but so limited with the controls. The sounds sure do bring back the memories.

    hello Adam thanks again for this nice discussion. As I said, I'm a hobbyist (like so many here) and all the money invested ... well, it's gone. I would like to implement a mechanical shutter and I know the validity of the Scannermax but at the moment I cannot invest an additional $ 600 plus...

    Hey Brad, I asked (also got some messages from other members) and got told to make it a "June Sale" for PL Members We're going to run a sale for general public too, given the demand, but their rates will be higher, the PL rate will be lower than anybody else gets To purchase - please email...

    Hi David; I'm enjoying the discussion. This sort of thing is exactly what PhotonLexicon is all about. :) Thanks for linking to the manual for the FB4 version of the Stanwax safety board. Reading through the manual, it appears that the board only supports a single attenuation method,...

    While I agree that the question of apparent brightness is a complex one that has many variables that are difficult to control for, speaking in very general terms I believe it is safe to say that an 800 mw green-only projector at 532 nm is probably going to appear brighter than the 2 watt RGB...

    Dear Adam I don't know how to thank you enough for your availability and completeness of information.

    I believe you are referring to the shutter output on the FB4. And yes, it will work with the Pangolin Vrad 506 actuator that you linked to. The Vrad is an *excellent* choice to drive a shutter, which is why I mentioned it in my previous post - along with the GM20. I'm not sure what you...

    Brightness is a complicated question for several reasons: Eye sensitivity as a function of wavelength depends on whether the eye is adapted for light conditions (photopic vision), dark conditions (scotopic vision) or somewhere in the middle (mesopic vision) It depends on the spectral...

    I don't know how 520/532 compare in terms of brightness but I think that the red in that cube is a bit weak. Also, if you are presenting text you should be paying attention to the galvo specs. They are listed as >8deg @ 30000 but I don't know. Check with someone who has one to be sure and see...

    I'm on the fence between a new controller for my existing 532nm 800mW DPSS system or selling it and going with a LaserCube 1W/2W RGB system... We mainly do outdoor, nighttime advertising of text for companies, so perceived brightness is the main factor for us. I found some specs online for...

    With whatever software comes with the projector :) Something like a LaserCube comes with software good enough for our purposes. Nothing fancy required, most of what we do is just plain text.

    I had my luck today and found a scientific paper that discusses micromachining Scotch tape with a laser. Apparently, it's the easiest way to get microfluidic devices to work. While 266nm lasers are probably still impractically expensive, it gives at least some hope that it is possible to...

    Hi Viktor, yeah, nothing suggests that 352nm would be substantially more absorbing than 365nm. But I still want to try, so I bought an LED with the following spectral response: This covers the target wavelength, even though it's only half bright at 352nm. Once the LED is here, I will...

    I have another post where I'm looking for a Standalone ILDA controller, but failing that, I'm open to a full projector that has the capability to run *without* a computer. i.e. something that has built in memory or an SD card slot to store the shows LaserCube type system would be an example....

I have not yet implemented an ILDA card in my projector, I am using FB4 with its features. FB4 already has a PWM output...

    The C=64 SID chip was pretty cool, and it still enjoys a loyal following today. There are companies that have built small Synth rigs around that chip, and you can still buy them today. (They are expensive though - much more than a used Commodore 64!) It's really crazy to hear some of the...

    Is that the correct style doorknob? I seem to remember the one that Ryan was using for the Laser Spectacular show had a lot more facets... Honestly, $80 isn't all that bad. I didn't think they were even making these things anymore... Adam

    Hello David; Thanks for sharing your experiences. Many people here followed a path similar to yours. I've been fascinated with lasers since the mid-to-late 1970's, but it wasn't until the early 1990's that I could afford to purchase one, and it's only been in the last 15 years or so that I've...

    A small update: before I can justify spending a fortune on the 352nm laser, I want to be sure that it would be able to cut transparent scotch tape. So far, it's the most difficult material in the mix. Since true UV lasers are expensive, no matter wattage, I had to resort to UV LED light to test...
