    Float Switch Relay Project - Looking for some help

    Hi Trevor, I can't see any specs for those switches stating what voltages(AC or DC) and current they are rated for. Do you have other information on them? Your 22watt 120vac pump only draws about 180mA, so you may be able to wire it directly through the float switch without a relay. If using...

    Looks like the elevator doesn't reach the top floor! Wonder if a bit of CA glue will fix that?

    Relay with separate switch integration

    As Harald advised, connect battery negative directly to the load and relay pin 85. Don't need to use the black wires on the switch.

    CanBus Switching from a Reversing Bleeper Circuit?

    Don't assume that there is a ground. Test to make sure. Can the dealer advise if reverse lights are an option? I haven't worked on a Merlo for ages and don't know anyone at the local dealer, so unfortunately I can't get any info on their wiring.

    CanBus Switching from a Reversing Bleeper Circuit?

    The Hella 996152131 timer relay would be a good choice, provided the beeper has a constant ground. The beeper would have to have the positive pulsed to work with this relay. Won't work if the beeper negative is pulsed. See diagram below. 30 - fused 12v battery or ignition supply 31 - ground 15...

    CanBus Switching from a Reversing Bleeper Circuit?

    Have you checked if the power supply to the beeper is pulsed or constant? The beeper may have internal circuitry to make the pulsed sound.

    Chop saw bosch 18 v

    I assume that the 5ah and 12ah batteries are fully charged and work correctly on other Bosch tools? Suggest you contact your local Bosch service agent for advice.

    Microwave sparking from side panel

    And some vehicles now also have to have the battery brand, part number, rating, etc programmed into the ECU when changing the battery. Not a five minute job any more.

    Microwave sparking from side panel

    Actually, this law does work quite well here in NZ. The shop can't just say, "out of warranty, go away". They also can't just palm you off to the manufacturer or importer. They sold it to you, so it is their responsibility to rectify the issue.

    3 jumper pinouts on R3 Arduino Uno

    This should help The Full Arduino Uno Pinout Guide [including diagram] (circuito.io) Arduino Uno Pinout - ICSP Header ICSP stands for In-Circuit Serial Programming. The name originated from In-System Programming headers (ISP). Manufacturers like Atmel who work with Arduino have developed their...

    Microwave sparking from side panel

    Not sure where you are located, but most smaller appliances are not worth repairing due to cost of labour, and the availability/cost of parts. Some of the higher price name brands may be economic to repair? Suggest contact the local service agents for the microwave, or an independent repairer...

    RELAY Omron

    AS PREVIOUSLY ADVISED THE COIL IS 12VDC, NOT AC. GET A RELAY WITH AN AC COIL OF THE CORRECT VOLTAGE IF YOU WANT TO CONNECT AC TO THE COIL ON TERMINALS 13 AND 14. AND YES THIS REPLY IS IN CAPITALS FOR A REASON!

    Oscilloscopes:2 Channel, 4 Channel, 100Mhz, 500Mhz etc.

    Would you recommend the digital types that connect to a USB port on a laptop, eg PICO, Hantek, etc I have a TRIO CS-1022 at home, and use a Fluke 123 at work, but would like a bigger screen.

    confused about full bridge rectifier

    What current does the coil draw? What is the resistance of the coil? 1N_4007 diodes are 1000v 1AMP. They will burn out if you try to put more than 1Amp through them.

    Gas Gauge Sending Unit question

    Thanks. That looks like an interesting device that I may have a need for in the future. Hope it solves your problem. One thing to remember with fuel gauges is that they usually show the depth of fuel in the tank, not the actual volume of fuel. A good example is a round truck tank. The gauge...

    Gas Gauge Sending Unit question

    These gauges don't require a regulated voltage supply. They are called balancing coil gauges. They have two small coils that pull the needle in opposite directions. One is connected to ground and the other to the sender. As the voltage changes the magnetic pull of each coil changes, thus...
