    Hey guys, both these circuits are the same except for the different types of components. Each cirucuit was cut on a CNC milling maching and soldered by hand. These are my first two circuits I've built other thank kits and things like that. Let me know what you guys think!

    Thanks,

    Nothing wrong with milling PCB's, it works.

    SMD components are far easier to solder than you think, just requires a bit of technique. You don't have to do a video there's already one which pretty much explains it all.

    The only thing you're lacking is some separate liquid flux.

    Your boards are fine but for usefulness you should make one with a pot instead of two resistors that way you can control the flash rate, SMD pots can be quiet tiny.

    The advertisement for Sunstone Circuits was nice.

    jpanhalt, it's a YouTube clip, you can't control the adverts.

    I never mess with you tube, if I can avoid it at all. I didn't realize adverts came with it.

    For a moderator:

    Doesn't ETO have a policy about having images stored on the ETO server? Shouldn't that apply to videos for the same reason(s)?

    Jpan, it's not an image it's a video. If you click the attach "Insert Video" link on your post editor you'll see it ETO tells you use these services, it has no direct support for streaming video.

    That was a good video by the original poster though, thanks.

    Look forward to more from OP,
    + but could he come up with a pcb clamp to stop the image jerking? The magnification fator on the viewer's screen means any movement is magnified too. Some white LED's arround the Lens would provide shadowless lighting.

    Would be interested in seeing the PCB-milling operation if OP can duct the swarf off-screen.

    yes video could be brighter, less shaky and better focus but still this was not bad. i have not seen through hole resistors of this style in decades. must have been salvaged from something old.

    Oh com-on! haven't you got some of those old gemanium transistors with black-paint on? . . . I have.

    -although they aren't earmarked for any Project, on the very-long List.
