    I want to make a speed limiter for my motorcycle

    I see a couple of things here: A motorcycle speed limiter is NOT an engine rpm limiter and they have been used with no distinction here, at least in the responses I glanced... A speed limiter takes a governor driven from a wheel. A rpm limiter takes a governor taken from a crankshaft...

    I want to make a speed limiter for my motorcycle

    My old cars with modern transmissions use now a circuit I made with a LM2907 chips to engage the TCC at a certain driveshaft speed. Such chip can be used for your task by shutting down the ignition or control something ...

    Solenoid alternative

    Hi. I bought an actuator to release a buoy from the sea floor a while ago. Like this, automotive; also available at near $0 at wreck yards : ---> https://www.parts-express.com/High-Power-Door-Lock-Actuator-2-Wire-330-010?quantity=1 I still have it behind some spider webs. Come back if you...

    Anyway to repair a LCD display

    Appears as a backlight flaw, not as a LCD problem. Measure voltage, current to backlight LEDs and source.

    Little solar powered battery and led.

    Welcome. 'Little' means nothing; 10 to 15W may not be 'little' for many. 4 lithium cell if in series, can be around 12V to 16V depending on chemistry and the charge voltage should be not more than 14 / 16.8V for the group. BMS board should be used then, and the solar panel should be of a...

    DIY load for generator testing.

    Not a simple fan heater, but several of them, like 5 at 1500W each. A couple of household water heaters, ---> https://www.facebook.com/marketplace/item/319094160504815/?ref=search&referral_code=null&referral_story_type=post&tracking=browse_serp:25995f47-ec07-41ce-bff5-c0f337cc9b62 --->...

    Tv oled not turn on

    What are each of the relay contacts connected to ? Some supply voltage that is not present in one ? And to a board supply rail the other contact ? Have you checked surface mount fuses for continuity ? Do not risk circuitry by jumping traces unless knowing what is being done.

    Tv oled not turn on

    Page A18 shows a pertinent P2300 with pins 1 to 8 in need of probing. But I ignore what DPC, DPIM mean or if those are active low or active high command signals. Did not follow where they come from. Pages 6, 7 show diagnosing procedures. Block is on page 28, more on sheet 8. Suggest you print...

    Tv oled not turn on

    Guessing !, your 3.5V can be a standby supply (3.3V) always-on to respond to remote control or local buttons. Not getting other supply voltages after commanding to turn on; the supply circuit can be in protecting-state or at fault. It is convenient to look at its schematic to discern how it...

    Lamp Replacement on Equalizer

    You do not know the voltage supplied when loaded by two working lamps and that resistor in series... Keep looking for the ones rated with the voltage you like.

    Did it ever work correct before ? Remove the probe, short circuit its input jack and come back.
