    Boost converter output voltage being limited by led current draw?

    Op's battery spec, could not see any maximum current draw listed. Name:Digital battery Model:NP-F970 Capacity:7.2 V 7200 mAh Size:70 mm x 58 mm x 37 mm Weight:291.8 g A rather expensive special purpose battery to be used for playing with LED's I would imagine.

    That was the Op's first choice in the first post.

    Weird Harley starter solenoid issue

    Looked at a couple of videos on 1970 to 1980 Harleys and see they use a system similar to the old Fiat tractors. Operation is.....power to the solenoid which pulls in the bendix gear and when engaged, the solenoid main contacts close and direct battery power to the starter motor circuit. Just...

    Weird Harley starter solenoid issue

    Never heard of a starter solenoid having a pull in and a hold in coil . I think you will find the small terminal is supplied power from a start relay whenever you push the start button. Return for this would be through the frame bracket normally. Then main battery power drives from one of the...

    Well, there ya go as they say. I imagine you learn something new every day then.

    Double Potentiometer

    The original pot would have to be removed if another is to be used. The wires of the old pot to go to the new pot in the same order. i.e. outer 2 wires to outer 2 positions and centre to centre. Then if the pot works backwards, reverse the 2 outer wires. The two cables on their own are power...

    Powering LED strip

    Chances are they are never going to flash in unison.......... if that is a requirement :) Don't think LED current will interfere with the pickup coils. They operate by the changing magnetic field right at the armature.

    RF keyfob & arduino.

    I wouldn't use just the keyfob on it's own...too many variables to even begin to sort out what goes on inside it.

    Convert two wire led to three wire for marker and blinker

    Yesss.....get that myself. Ok...try Google as there are many circuits there. If you check it you can decide which suits your needs best. As you say , maybe just a couple of diodes. Voltage drop should not be a problem but if you need to keep it minimum use Schottky diodes...

    RF keyfob & arduino.

    Most are termed wireless relay for that exact reason. i.e. the output is a relay which can be set as....... on and off with button press and release...... or press on, press off...or one button on and another button as off. Available either as 315 or 433mhz. Not much range but there are some...

    Convert two wire led to three wire for marker and blinker

    At $3 odd, maybe buy one and cut it open, have a look at what is inside.

    Powering LED strip

    That's never going to work with your LED strip. One here on youtube uses 12V and a 5mm flashing LED to turn the gate of a mosfet on and off at the flash rate of the 5mm LED. In this particular case, this in turn operates the high power single 10W LED. All you would need to do is replace the 10W...

    Water level meter

    As I said earlier, conductive probes will not work in distilled water. There are capacitive probes available quite cheap on Ebay. Normally used as a sensor for Arduino. Output is analog i.e. from 0v to 3v so you will need to use with Arduino or some other form of interface if you need to...

    Searching fusible resistors

    Perhaps you don't mind paying $24.00 for postage on a 60 cent resistor but not this bloke thank you.

    Is this voltage and amp schematic correct?

    You did ask for help here and the points I made were directly at the errors/omissions. If you cannot handle advice then that is your problem, get a life. I am well versed in circuit diagrams and I can assure you I do know how to read circuit diagrams. The snippets you presented made little...

    Searching fusible resistors

    Currently have a 220v ac LED driver with a pair of blown 400v capacitors which also took out an inline 15 ohm fusible resistor on the bridge rectifier input. Searched around but found the replacement resistor options rather limited and expensive. Intend to bin the whole box and dice but just...

    trying to understand amp limits? (10 vs 15 vs 16A)

    No truth in that comment what-so-ever. Any "professional electrician" worth his salt would never make such a ludicrous claim. I am a qualified lecky,and contractor with many extra post trade certifications and 50 years experience however, I've never had to make a claim that I was in any way...

    Is this voltage and amp schematic correct?

    You'll need to provide a complete diagram as what you have here, although it might make sense to you, means next to nothing for others. It is normally not a good move to get pcb's made until you have at least done a test run with components. No idea what you are trying to do with the two...

    12 / 24 or 48v to 400V Boost Converter to charge electric car from solar panels

    Not in to designing boost converters. Tend to leave that to the manufacturers. Several reasons including cost and time.
