    Is bluetooth safe?

    One thing I noticed, when scientists says it’s not harmful they are always on some big telecom company’s payroll! Maybe not at the first glance but if you investigate deeper that’s what you will find!  8)

    checking for proper earth grounding of wall outlets

    Well, this does not reveal the colors of your wires. Where I live we have earth (ground) wire green/yellow and neutral blue; these are connected in the service junction box (hot (phase) is black or brown). If I measure the voltage between the blue and the green/yellow wires it must be zero...

    checking for proper earth grounding of wall outlets

    I don’t know where you live or what colors you have on your wires so it’s hard to guide you!

    shake light

    Thanks John, interesting! I noticed that it has the same author as the two articles I posted earlier, he must be an expert in reusing steppers! ;D

    Re-winding tranformers

    Not all are welded and not all are E I core, some are toroide transformers. Usually the secondary winding is the outer layer (on top) and can be removed and replaced with some effort. When removing a secondary its always a good idea to count the turns, this gives an idea of how many turns you...

    Is bluetooth safe?

    At least as little as possible, you never know.

    Re-winding tranformers

    Hi Chris, It depends on what kind of transformer you have to begin with and what you like to do (what you want to change). There are different ways to go about it, some harder then others.

    Electronic parasite zappers

    Hi Steven, Always busy with new projects, great work keep it up! ;D Just one caution, the NE555 might be toast at 18 Volts. Its maximum operating voltage is 16 Volts according to the datasheet. Take Care! ;)

    PCB drill press design

    Yes, that’s what I was thinking about. Not a bad picture, just small! ;D Let us know how it develops!

    PCB drill press design

    When I magnified the pic I could see you got it right! If you need it to push on both sides make the lever arm in one piece (U-shape) and put a hinge on the back of the press, something like this: The red thing is supposed to be a hinge, the blue is the lever and the view is from above! ;D

    PCB drill press design

    Another lever arm might not prevent the thing from sticking. The picture is not clear enough to show if any of the joints (screws) have some sideways slack, it should have because the distance between the two screws varies as the tool holder slides up and down. ???

    It doesn’t look too bad I think! At least not where you have pointed the camera! ;)

    PCB drill press design

    Yeah, the mechanical parts where fine but the scanner sent out smoke signals after the wall wart got faulty serving 30 Volts to the unit in stead of 16! A pcb with plenty of surface mounts got fried and I signed the death certificate immediately! I saved the plastic covers, the glass and the lid...
