ID:	43229Well if you have followed my efforts over the last year on making a mini low power programming projector than you know I first had the dichro issue to solve. Check done thanks to Dave and Bridge. Special mention to Fred at one stop for trying as well. Had to build up a small rgb module. Check done thanks to logsquared. lovely piece of machining. Diodes from DTR thanks for a great site and service. Needed drivers Thanks Andrew for the new run. Well that got me to a completed 200mw light source. Then Bill made the 506's and turned the idea of a miniature scanner on its head. Add some driver sauce and finally I'm ready to assemble the unit. I'm going to buy a 12"x6" piece of 1/4" alum for the plate because once again the heat issue thanks to bill is no big deal BUT I am hoping to get it all on 6"x6" of the plate and chop off the extra 6". Better to have the extra space than need it. When done I am pretty sure it will be a 6" cube with a window on one side and a power cord and db25 on the other. This thing will draw less that 2A weigh under 2 lbs (way under). Now with a laptop I can sit in total silence and get the equivalent of a 60x argon and 30mw hene combo that cost 3k and drew 15A. This total build is less than 2k. Add in a fb3 and you have the ultimate hobby box. If you take away my mistakes along the way you might be able to do this under $1200.00

    I'm doing the build on Monday so look to this thread for pictures of the unit. PS: it would be no big deal to change the rgb unit out to be well over 2W in the same space. I just wanted the beauty of single mode diodes. You can easily use the 120mw green in place of the 50mw in the same unit I am using. I am sure logsquared could offer the metal work as a kit. He doesn't make completed modules so you need dichro, diodes, lens, and drivers. Looks like I hit the bottom of the text box..............

    The last pic is my existing 12x18"x12" projector for comparison. This all fits on a 6" plate and is 5" deep with space to spare. Tomorrow is drill tap and assemble

ID:	43240well assembly went ...ok three broken taps but who's counting. Please see the attached pictures. I got a rough together and now just need to build a housing for it. Works very well. I'm using pt20 amps at 18V! This thing rocks. I am running the drivers at 9V for the diodes and even had it on a battery.

    More to come once I do the test patterns and build the box. But as you can see you CAN build a complete projector in your kitchen. 6" was generous. This could easily fit in a 4" cube. Also while I used the single mode diodes, you could easily squaeeze a watt or two in the same space.

    It is a blast to sit in my living room on my chair with the projector next to me and my laptop and program. Look for new shows.

    I really need to point out the rgb source. Thanks to logsquared or this would have never happened. Thanks to Bill of course or this would never have happened. Those 506 scanners rock. I can only wonder how they would perform on good drivers and 24V!

    Still trying to figure how to upload a mov file

    beautiful. these little single mode micro projectors are so awesome for show creation and living room laser shows.

    upload your video to youtube and then link it with the film strip icon.

    suppose you're thinkin' about a plate o' shrimp. Suddenly someone'll say, like, plate, or shrimp, or plate o' shrimp out of the blue, no explanation. No point in lookin' for one, either. It's all part of a cosmic unconciousness.

    test mini2.avi

    I figured it out! Can only take avi. That is a piano under the sideways image for size comparison and I'm a good 10 feet from the wall. Image is about 8' across. Very respectable brightness.

    Also the squeeze is the video not the image. It's round.

    no that's chuck rau on digisynth. come to think of it I think I used something from almost everyone on PL to do this! This is for sure a non denominational projector.

    swami if you look close on my large projector you'll see my trick. it maes the higher power look single mode. I put a 3x on the blue and then run the whole thing through a 2x. I let the scanners clip the edges and you get about 70% power out but 1 mm thick beams at 15'.
