    predator 9500 inverter voltage output measurement

    Be careful quoting handling capacity of generators in relation to any motor. They will draw 4 to 6 times (depending on type) at startup and drag the output voltage down. Result being the genset sags and the motor never gets away, at worst, burns itself and/or the gen windings out. As for the...

    Can I remove DC motor driver's speed control potentiometer and drive it with microcontroller DAC output ?

    There will be a 555 timer underneath the electrolytic cap. https://www.electroschematics.com/review-of-the-hw-687-dc-motor-control-module/ There are other similar mosfet modules (D4184) with opto's that will take a separate pwm signal as an input. https://www.aliexpress.com/item/4000302453083.html

    Attiny1606 burning out when controlling a drv8251

    Seems quite a lot of info missing from your circuit diagram which only introduces further questions for an overall view. Specs for the DRV8251 say supply voltage starts at 4.8v. What is Q1 supposed to do?

    How to measure 3V battery lifespan?

    R1 your gate resistor..??? Are you sure..??? Switch position...??? Would be more obvious if you marked "load".

    pls help need to pass for my finals

    There would be several around using a 555 timer. Operation is not strictly flip flop but it does flip from one setting to another and then another depending on button presses.(or not)

    Assistance Identifying component L2

    That will not measure the infinitely small resistance of a few turns of enamelled copper wire, so forget it. Do other as I suggested above.

    Assistance Identifying component L2

    I doubt the Op would firstly have the gear to measure that plus it appears burned so again, no deal. 5R6 would suggest 5.6uh. Details on the mosfets not clear in the photo, either Q9 or Q12 which appears to be the same so one could possibly test there. A closer look (better photo) of the coke...

    Assistance Identifying component L2

    Inductors rarely if ever fail on their own. If it's cooked as it appears (photo could show this much better) time to start looking else where on the circuit as well.

    Wiring diagram of 18650, HX-3S-01, XW228DKFR4 and a LED strip

    Charge socket does not look correct but difficult to say as image does not show the connections properly. Do you have a link to the parts details? Looks like you have 2 (red) positive leads on either side of the panel socket internal switch and if they are not the correct orientation, your unit...

    Rice cooker tripping breaker when switched on (Zojirushi NP-HCC10)

    Ok...when testing diodes, you need to have the meter on "diode test" to bias the diode on, which it appears you have done. Then you need to test for forward AND reverse. Youtube will again show how to do, but it appears the bridge is kaput on the negative to AC legs. example ...

    Rice cooker tripping breaker when switched on (Zojirushi NP-HCC10)

    DB (first photo) shows dead short on bridge rectifier AC inputs and the negative out. No reading shown for the positive out. If this is the case then remove DB and test out of circuit...plenty of instructions on youtube etc. on how to test. Note that removal needs good soldering ability and a...
