hi
love this site, ive been trolling for awhile now and grabbed as much info as i could for my build, on a shoestring using an LX8383A (3.3) as a regulator, it seems to work well giving around 2v at 30ma powered by a wall wart at 4.5v 500ma, tho ive got an old A.T. supply im think of using, will test with some diodes and leds 1st tho.
im also using dvd sled with LD but without the focus lens,using the inbuilt collimating lens, a great suggestion,i believe by one of the members here (sry ive no name, but ty ), i do have an odd problem with the sled out of an NEC1300A burner, although its collimated it has extra beams a bit like this
. o . O . o . (these are all in a perfect line about 2" at 1m, with the main ~5mm beam in the center)
im not sure if its an internal optics problem or by design, any idea?
being on a shoestring is tough as i want to try my hand at holography or pattern projection (as i have a number of stepper motors now, lol), but as far as learning electronics and optics go, i cant think of anything more fun
thankyou all for your advice and mad skills
