    Flyback transformer?

    It's not a problem not understand something. One can usually learn to understand. What can be a big problem is when ignorance causes one to blindly do things that can lead to bigger and often irrevocable problems. In electronics repair, one must take a methodical approach and understand the...

    Headphones keep looking for Bluetooth connection, while connected - trying to figure this out.

    I can't see enough detail to discern how it works, but it looks like it failed due to corrosion (water entry) near where the wires terminate. Try to get a number off of that 6 pin smd component on the left side of corrosion to figure out what it is. It looks like there's two separate contacts...

    Flyback transformer?

    I don't know what 126 is, but a 4.7uf cap shouldn't be replaced with a 47uf. Sounds like you've fried some discrete component(s) rather than the flyback coil.

    Door Bell Chime Transformers - UK

    It should be warm to the touch but not so hot it will burn you if you leave your hand on it. Make sure your door buttons are not sticking on which would make it get hot by continuously drawing current. You can try taking off a wire off the low voltage side (wire to chime)and touch it back on...

    HIC Identifying Component

    Looks like a solid state relay. How do you know it needs to be replaced? Have you replaced the light switch and it still doesn't work?

    Need a simple adjustable device to lower signal voltage?

    @hevans1944 Seems you answered your own question with that well written post. He wants to offset the O2 sensor feedback to make the engine run more rich. Presumably to attempt to increase horsepower.

    Questions board with SMD components

    Yes, similarly to how it came from the store or factory.

    Panasonic TX-32DS503E blinking red light.

    I blinks continuously? I thought it would turn on green and you start counting the red blinks. It should blink up to 10 times and then likely shut off to protect itself. Try unplugging boards one at a time and see if the led light goes back to solid green.

    Questions board with SMD components

    No external power backup is needed for flash memory cards like TF or SD cards. I can't give an accurate answer about corrosion and oxidation because it depends on the environment. If the board is coated with a monolithic coating or varnish, that will greatly help protect it. If its in a damp...

    Questions board with SMD components

    If I understand you correctly, No. The board itself should work fine regardless of how long it has been left unused. Although the memory storage may only be good for a few years. I will say you could have trouble using this board if you continue to place it on the carpet where static...

    Panasonic TX-32DS503E blinking red light.

    You don't say how many blinks you get but I counted 4 and then video ended.

    VFD (Variable Frequency Driver) for 3-phase motors.

    Yes. It does exist here in residential applications but it is rare. It works perfectly for places with 240v because you can perfectly ballance all 3 phases but if you have 120v household it gets a little unconventional having to mid-tap the transformer to create split phase 120v and 240v, 3...

    VFD (Variable Frequency Driver) for 3-phase motors.

    I agree but price aside, It's likely you can't get 3 phase service anyway. More than one service fed to a residential house isn't allowed, and a 3 ph delta(4 wire) feed is usually denied by either the utility company or your local authority. Better to change motor to single phase 240v (rather...

    Wireless signal needed from motorcycle to backpack - don't know how

    Thanks hevans1944 for that highfalutin explanation. Seriously, well put Thanks. That's what I meant by multiplexed. Serial digital datastream of signals that are stacked together. I not a microcontroller guy but I understand Arduino is popular. Inexpensive price and quite user friendly . That...

    Terminals and Connector Sizes

    That works too. I've also just snipped a little off the ring end to make a quasi-fork terminal.

    Wireless signal needed from motorcycle to backpack - don't know how

    Thats fine but like I said, I don't believe the signals can operate simultaneously like would be needed here. I don't get the microcontroller idea. Wouldn't you need 3 transmit/receive signals anyway, even if you were to use Aurduino? Or is it a multiplexed signal?

    Wireless signal needed from motorcycle to backpack - don't know how

    I would investigate how the remote works. I believe the 4 channels work independently so you wouldn't be able to control two signals at once such as the brake light and turn signal. It's likely that only one remote control button can be pushed at a time.

    Wireless signal needed from motorcycle to backpack - don't know how

    Or, go old technology and use a "coil cord" and plug in your backpack. Yes it'd be more cumbersome, but with the added advantage of not needing to keep a battery inside your backpack.

    Terminals and Connector Sizes

    My picture shows a sta-kon crimp lug size RA18-6FS which means 18awg wire and a fork that slides onto a #6 screw that has a diameter of .13in or 3.3mm It should fit perfectly. Edit: Yes the tips of the forks do turn up slightly, but they help hold the lug under the terminal when tightening. If...

    Terminals and Connector Sizes

    Personally, I'd use these I disagree it's not good practice to not use ferrules, particularly on plate type terminals like this. I often give strands a slight twist and when using small gauge wire, I just strip wire back longer and fold back to double up the wire before inserting in terminal...
