    can the leds be mounted into spray foam insulation

    Why are you using spray foam insulation? Would something less flammable (e.g. mineral wool, glass fibre) be ok instead?

    Price versus quality

    Even if you find a suitable pot, how stable is your power source supplying the pot? It would need to vary by no more than 1 part in 500.

    Can someone suggest me an upgrade for my car that doesn’t require any wire cutting or voids insurance and warranty, but still gives an excellent econo

    Welcome to maker.pro! I suspect that if any workable device that met your conditions had been invented it would already be incorporated in existing vehicles or at least would be widely available on the market. Beware of snake-oil salespeople.

    Forward reverse switch HELP!

    Those controller specs are fine for that motor, but the DC current rating of the switch is not specified and its AC current rating is marginal.

    Forward reverse switch HELP!

    What is the current rating of the controller? If it is less than 3.1A then it is probably going into self-protect mode when it tries to start the motor (which has a 3.1A stall current rating).

    Forward reverse switch HELP!

    Welcome to maker.pro. 1) What are the rated full speed current and stall current of that motor? 2) I see no DC rating for the switch, so it may not be happy if motor stall current exceeds an Amp or two.

    Help Modifying Constant Current LED Driver from 700mA to 400mA

    If it were a variable resistor you could tweak it slightly and check to see if that affected the LED current. If it were a voltage reference then there would perhaps be a comparator for comparison of that voltage with the voltage dropped across a LED current sensing resistor. Changing that...

    LED lamp goes "poof"

    Good to know it's now working.

    LED lamp goes "poof"

    Don't think so. I'd guess it's there to discharge the cap safely in the event of the current-limiter IC failing open-circuit.

    Loud pop on transducer switch

    What power supply do you have? How are you switching the board on/off? Are you switching just the audio channel, or just the supply, or both?
