    New little toy

    Well, It's not a CNC, but it's kind of fun. I've been wanting a way to make PCB's for some of my electronics projects. I discovered a method where if you have a laser etcher, you can paint over a copper PCB Board, and use the laser to burn off the paint, and then acid to remove the copper from those areas. Well step 1 is to get a laser. Found a small little one pretty cheap, delivered from china.

    It came with no assembly instructions, but I managed to put it together pretty easily, and hey, the darn thing works. Still need to figure out the fine tuning, but I can see a lot of uses for it.

    It can burn through paper and cardboard, maybe thin balsa wood. So far all I've done is just play around. But it is kind of fun.

    Neato! It is CNC though, isn't it?

    You know, I reckon it is, even if it doesn't have a router attached.

    cool indeed I remember back in the 70's we would do a tape up mask of the PCB traces by hand using a black tape on a clear substrate. Then using a photo resist on the copper and use a light table to expose the treated copper board. then we would acid was the copper to get rid of the excess. this would certainly be less tedious then making the mask by hand. It would also make changes to the design easier.

    Nifty (just for a break from cool).

    What's the specs on the laser as far as focal length and power?

    Not sure about the focal length, but it is 'focusable' to several inches.

    It's 500mw at 445 nanometers (violet).

    It can't really cut much other than paper, maybe cardboard, but that's not why I got it.

    Something went wacky on the board yesterday, I think a transistor blew, so Am researching options for a replacement board/transistor. Darren has been invaluable in helping to figure that out.

    Basically, the laser stopped 'turning off'. Going to go out and do a little testing to figure out exactly whats wrong.

    So it's out of commission for a little break, but when it worked, it worked great.

    I kind of knew that I'd be facing some issues like this buying something from china.
