I have bough countless 128MB 256MB 512MB 1GB and 2GB cards and none work with the SD card interupter i have. Pain in the ass gave up on it a while ago.

meee too :-)

Sweet! Yeah both in kit form!

haha cardboard FTW!

24VDC SSTC Audio Modulated Flyback Driver

There's still a problem with a humm in the arc with the current board, im ordering new fet's and will be sending a kit to Sigurthur to fault find soon. Ive also have 2 other projects of interest getting ready to go, 1 is a full audio modulated flyback driver and the other is a 24V SSTC, i have...

i haz this one:

The tesla resonator and breakout point govern the whine too as ive found, ill be sending sigurthr a kit to fault find, fingers cross everyone!

Its in the works, just need this whine to be fixed and ill go into production, Sigurthr maybe just the man for the job. I also have parts for a SSTC kit that i may release after.

Haha sweet I shall send you a kit soon!

I was thinking Id send you a kit to fault find!

That would of been the prototype coil I sent to things!

IN-18's are worth upwards of $50 per tube!

Sweet! Im a electrician by trade with post grad engineering :-) If you are keen to learn from others you will learn a lot on this forum!

Welcome! What is your trade of choice? chippy leco plumber? You will learn lots here son, Fiddy.

First of all the LM317 is a linear regulator and is inefficient and only rated for 1.5A. Id suggest a high current buck driver, i have a 9A version running a PT54 LED and it works well. Second, the LM358 is a OpAmp not a regulator. Thirdly, 9 LED's run at 3A each = 27A draw, at 3A the Vf of...

What driver you using? It has horrible beam specs being a multimode diode, not the best for engraving.

So your installing it into an CNC engraver? Theres no graphs for the glasses so i dont know if they are good at all.

No, its not safe, its more dangerous than visible lasers because you cant see where its pointing exactly and you cannot see reflections, you will get bored of it quickly, you will need IR laser glasses too.

Just got 4 of the boards, set one up nice, running from 24VDC and pumping out 3A in CC mode, bugger all heat produced in the driver, installed it onto my garage door motor light terminals for a test and it went BOOOOOM! The input capacitor exploded, retested the supply volts and it was around...
