    Microinverters and storeage batteries?

    Look into off-grid solar.

    Why can't I breadboard this oscillator?

    I don't like the provided circuit. Many improvements of the wheel have accured since the stone age.

    Why can't I breadboard this oscillator?

    I am trying to make use of these 15KV coils on ebay. Sure the circuit is stressed, but it should still work for a time. As my last-ditch effort I put in some 1N750 zeners from the bases to ground and reduced the inductance of the primary to 80u with resistance of 410m ohms. Haven't tried to...

    Why can't I breadboard this oscillator?

    It's 2MHz pulses at 38KHz. Shoot, I didn't try a decoupler. I'll try it in the morning, thank you.

    Why can't I breadboard this oscillator?

    I hate communicating. I've simulated a nice circuit for my purposes and find I can't breadboard it. I've checked continuity on all connections before powering, but I've failed to get it running. Any thoughts?

    LTSpice initial conditions help, please?

    What construction technique do you use to make boards?

    Electromechanical simulation.

    Thanks everyone. I have LTspice, but it seems daunting to begin the simulation of motors. I thought there might be something on the internet specifically designed for motors and power transfer.

    Electromechanical simulation.

    I was hoping to set parameters such as pole numbers, wire turns, permeability of the armature, resistance of the bearings, etc.

    Electromechanical simulation.

    Are there good electromechanical simulators? I wish to simulate AC and DC motors and generators.

    how to work on pcbs that are thick

    I would measure the heat of the board as you apply heat to it.

    Be careful when bending back the plastic tabs that hold the terminals in place.

    Output transformer of homebrew inverter.

    I am having trouble getting the correct current, out of the power transformer of an inverter. Have I made the correct transformer? Where's my flaw. Yes the circuit oscillates at 120Hz and not 60Hz.

    Diagnosing a JVC DT-V100 CRT Monitor - more an electronics question...

    Best I can say is to keep following the circuit from the transformer with the voltmeter untill you find no voltage.

    Piezo Ultrasonic transducer driver

    "Is configurable" I stand corrected. I would think the OP would want AN0 for analog measurment.

    Your thermistor is using the wrong pin.
