    Yes, as a practical matter, most use of clear tubing is inside enclosures and most others will be black.

    Heat Shrink Tubing

    When color isn't needed for cosmetic or color coding purposes, use clear tubing so you can see what's under it.

    dunk tank

    It's more like adding bearings to the wheel. I hope you plan to construct a green screen and chroma key in some interesting background scenes and/or add some lighting and music.

    dishwasher electronics problem

    The fault may be a bad heater, float switch, valve or some other simple component. The design of the timing circuits on most of these machines have no error trapping or timeouts; they just wait indefinitely for a temperature sensor, float switch or other condition to be met before continuing the...

    New LED light fixture is too bright

    There is a possibility that the supply has a lower limit to it's output voltage such that as you short (bypass) additional LEDs the supply voltage may not drop correspondingly and excess current would be driven through the remaining conected LEDs. If you have a multimeter, you could measure the...

    3x LR44 battery holder?

    You can at least get the contacts from Keystone or MPD. Just treat your stack of LR44's as a very short AAA battery.

    Bicycle project - Need help designing circuits and advice on the project.

    You're probably going to need a battery to run your lights and effects. The dynamo alone won't be enough. You should also consider using only LEDs for all lights and effects since they're efficient and shock resistant.

    is this chirping from the electrical wiring?

    Smoke detectors also do that when their Americium is depleted so if changing the battery doesn't solve it or the detector is more than 15 years old, replace the unit.

    Variable Transformer & Home Made Resistor

    No. I've used some for testing power supplies but never purchased them. Google or check Digi-key, Mouser, etc. Precision costs more and higher wattage costs more so you need to get your specifications nailed down before looking for prices. If no precision is needed, you could do something...

    Variable Transformer & Home Made Resistor

    It can be large or small, depending on your wattage and runtime requirements. A 4kW unit could fit into approximately 150 cu in. I'm guessing based on the appearance of your homemade unit that it's less than 1kW.
