    What are those components?

    TI has a part again with a partial match 7HU. TL4050B25QDCKRQ1 Again not 100% on this but might be something to look at.

    What are those components?

    Not 100%, however the AAPQ could be a MAX823REXK+T The marking shows 4 spaces and an AAP so the Q could be date/lot/Temp

    What connector type is this on aerobic septic system control board?

    Take a look at this connector from Molex. Looks Like the right one. https://www.digikey.com/product-detail/en/molex-llc/0430450212/WM1789-ND/252502

    Too good to believe...?

    I have ordered a lot of electronics from banggood for an afterschool program I work with just do to price. I always order twice what I need because half always seem to be bad and their customer service is terrible to work with so getting replacements is often not an option or takes 30 days to...

    I'm looking for 12v. LED's in red and yellow that cast light like a regular bulb.

    I was having a hard time finding a larger angle LED that would work on the 12v he was asking for. I agree if you have the ability to use a driver there are a ton of high power options that would wider angles. Since he did not reply to the COB option above I was just throwing out additional ideas.

    I'm looking for 12v. LED's in red and yellow that cast light like a regular bulb.

    I wonder if you could do a bulb like LTH5MM12VFR4100-ND this is a 12V 4500 mcd LED. Only has a 16° lights, however maybe with a lens like L30031-ND it may give some decent light. Not sure it would be enough for a room light though. At least not just one of them. Also have same in yellow...

    Device to measure total run time of an electronic instrument

    While I am not sure of anything made that you can just plug in and it counts when current is flowing, however if you have access to the schematic you should be able to add an hour meter to a point in the wiring that has power when switched on it would count and it would not when switched off.

    Help required with identifying a component

    Without a better pic of the component i can not verify 100%, however the S1G would be a callout for a 1A 400V Diode across many suppliers including Vishay and On Semi. 72 is likely a date code. Here is a cutout from a Vishay series and their symbol S1G. No their marking would be SG so it is...

    1/4 inch mono jack 3 pins

    This is not your switch, however easy to test. Continuity between the two post with no plug installed and open with plug installed or open then closed.

    Project help wanted

    Well first you will need to define some things such as what you consider to be good quality images. What you want for battery life. Once you have those basics down you need to find yourself an electrical engineer and they will help design something that will likely not be efficient as live...

    Shut off 12 volts 5 amps

    Are you thinking of something like a mechanical thermostat. You may have to look at switching and reset temps though as they normally switch at a higher temp and reset at a lower temp. So you would need to take that into consideration when choosing a NO or NC circuit.

    Triac Problem

    Q401E3 from Littelfuse might be an option assuming that it is a problem of not having a tough enough triac. If there is something else failing that is causing this part stress beefing up the triac may just cause the other part to fail.

    Electric Mower repair

    Have you looked in the manual for troubleshooting. Some of these the blinking light will tell you the issue. i.e. 3 blinks means this or 4 blinks means this. Maybe not for this, however generally a blinking red led is telling you something. If not is sounds like there is a safety switch that...

    General Electric Questions

    I think it would be best to run it with a fan, that said I believe that it is looking for a pwm signal to show that the fan is there and working. You would need to replace that in order to show that a fan is there. I am not sure how "smart" the system is if it is looking for a responsive signal...

    Help identifying component

    I know at Digi-Key and I imagine all of the Big Distis there are Jumpers for the Euro blocks that look something like this. https://www.digikey.com/short/j47qvf If you have pitch and number of positions I can try to help locate a better example.

    Resistor to limit current to circuit

    Why would you need to limit current to 200mA? If your draw is only 125mA then that is all it should pull. If you are worried about a short you should look at a fuse.
