Haven’t taken a look into it yet, but we’ll post our findings when we do.

Hi, I put the OIKit.framework from my iPhone into Xcode and I’m using some parts of the code from serial.c to access tty.iap
How did you actually manage to write to that port?

He didn’t pay $6 per laser, he got them for 40 cents a piece on ebay.

I would consider this a relatively poor design since 35 lasers has far surpassed the point where a basic scanner would have been cheaper, smaller, and far higher resolution.

As well as that, spending 6$*35 on lasers is borderline insane considering you can get the same model for around two dollars and these (which are identically speced) for 0.98$ (10+) including shipping.

Congrats on wasting your money on a wasteful design.

and for extra hackage, you could use surplus PS3 diodes. Obviously for sensible cost you’d want to use a 4*4 or a 4*3 matrix, but it would project multiple colours and shades.

Driving them isn’t that hard, you just use a small LM317T based driver and have the PIC etc “step” the current to one of four levels.
