    Harbor Freight Centech charger putting out around 150V

    Could have an internal short on the transformer ....best take it to a service centre before you electroplate some bystander.

    Newbe need help with solenoid kicker project.

    Don't think you're going to get much assistance to design a gun, regardless of it's name. Many places it is considered highly illegal.

    JVC cassette deck won't stop at the end of a tape

    Might be a pulse from the reel and when the tape runs out , so do the pulses.

    Is it safe to splice these two power cords?

    In Aus it would be a BIG no-no. Other countries, who knows.

    No voltage readings yet..??

    NAD 3020A Amplifier Low Volume

    Not knocking your meter, I use a similar analogue meter myself sometimes. The meter must be capable of providing enough bias to turn on the junction of a semiconductor. It is why you will see modern digital meters with a "diode test" range as their ohm scale just will not work. Normally...

    Has anyone here ever used a serial screen?

    Best to get yourself some gear and get your feet wet, so-to-speak. Better to get hands on and try to avoid copy and paste of the code. Read it up by all means but you will learn a lot more if you try to write the code yourself. If you get stumped you can always go back and read it up once again...

    NAD 3020A Amplifier Low Volume

    That old meter may or may not be capable of providing enough bias to test transistors. Usually when they have a x1 range but none on this antique. Could verify by testing say an 1N4004 diode or similar. What are you using as an input..? What sort of voltage levels are you getting on the...

    Has anyone here ever used a serial screen?

    You might want to look at an Arduino approach. Clone Arduino boards work fine and help keep the cost down. There would be plenty of circuits and advice out there for a basic touch screen running on I2c with library support also to get you started. Just what you intend to display is unknown but...

    Replacing LCD instrument readout with LED readout.

    FYI an Ebay unit for $5.00 has a better claimed accuracy than your $75.00 unit....:eek...

    3 Phase motor starter for a 1 phase motor (FNG)

    Still say it's not necessary but if the Op needs control via a control circuit, say for a control isolator such as emergency stop, or a foot switch or whatever, then one would need to know the voltage of the control. If it is originally derived from the 3 phase i.e. 415v then forget it. If there...

    3 Phase motor starter for a 1 phase motor (FNG)

    Why would you need a starter for a single phase motor of that size? Just plug in and turn on.

    Paper Shredder Fault

    Time spent so far is in determining what you have in front of you from your replies. So if it is taking too much time for your liking, there is only one source of the problem. If you have 5v available across the existing IR LED, then a red led should work......so what have you done there.....??

    wet feeling when using electric coat, how to remedy?

    I'd consider that a medical issue rather than electrical/electronic.

    alternative XT60 connector for live circuit?

    Then simply turn off the supply first.

    alternative XT60 connector for live circuit?

    Show your application. Most that use these plugs have the main load current isolated during plug in. If in R/C, the receiver or esc boot up current would be of little issue.

    Paper Shredder Fault

    Fine but....last time you tried to run it you said it would not go anymore......so the point is.....was the switch in the right place to run, either forward or reverse............NOT centre position.
