  • You may or may not be interested to hear that I took your warning to heart and I’m now planning on using an actual DC power supply, coupled with either a resistive or inductive ballast which will also be designed for that purpose.

    I’m sure the original plan is easily workable for someone with training or education, but for an amateur, it was too far outside the box to find reliable information and feel confident in it





  • This is, hopefully, going to be functioning as a current- limiting ballast for a solid state tesla coil. So I need the 1.1A it draws, but not the motor.

    I just wasn’t sure if that 1.1A would stay constant if it was just the primary coil, without the motor.

    I agree it’s a weird question, but it’s because the instructions I’m following are very vague about what to use as a ballast. The guy says to test the circuit with an incandescent bulb, then use a hair dryer, toaster, or other household implement that draws a couple/few amps. I’m trying to figure out the bare minimum of components from a device that will still draw current







  • I’m not proud of it, but I got like six little, ~2", brass-plated L-brackets from home depot and attached them along the long sides.

    It’s not ideal because TECHNICALLY wood movement could be an issue, but movement with the grain is minimal, and I needed to just get the thing done so I risked it. No issues yet and it has been in my basement (which has pretty significant humidity swings) for probably a year now.

    Also, but a dumb question, I reached this exact point in the build, when I had a frame and a top and was like…well now what?









  • I’m the middle of reading your comment I realized what I did wrong when making it in the breadboard.

    So I got the switch and parallel LEDs working, but the single LED connected directly to positive wouldn’t light. The resistor and LED made a loop back onto the same positive side of the breadboard, so the current had no reason to flow through them.
