    Aiber Water flow sensor

    Thanks St Edd. The only way I'm going to know that my replacement hall sensor is working correctly is by taking readings on the new one and comparing them with readings on the fixed one. But then I need to know what sort of signal to look for. Voltage spike, current spike, some 5v on off business?

    What about capacitor C5? Looks like it's been knocked

    Aiber Water flow sensor

    Thank you so much Harald. I hope you are spot on. I think all I can do now is the"suck it and see" approach. I have found these locally. Although rather expensive better than having to buy 3000 https://www.mantech.co.za/ProductInfo.aspx?Item=14M5636

    Aiber Water flow sensor

    This water flow sensor stopped working .It's part of the control mechanism in a gas (LPG)geyser. The 3 legged magnet sits in the pipe to the left of it. It senses water flow by by being forced up the pipe to in proximity to the 2 green wire bit which is a switch that gets closed when the...

    Spidyy Can't see that you need to remove any heatsinked components. You can get to their legs and that's what you need

    Davis Vantage Vue weather station

    Hi Durman Thanks for the additional information. I suspect every single Davis owner has wished that he didn't have to replace that battery. I didn't get if you replaced the supercap. Did you?

    Magnifying light voltages

    Hi Bertus Thanks Unfortunately I have already started stripping leds off the board.

    Magnifying light voltages

    Using an online calculator from the resources section I get: Source Voltage = 12V (Assumed) Diode forward voltage = 2.5V ( Guess) Diode forward current = 20mA 30 Leds 3 x 10 arrays + 270Ω resistor on each array Circuit draws 200mA I know nothing about these leds so all guesses Does this look...

    Magnifying light voltages

    Thanks Bertus Trying to get my head around this. With leds in parallel the cathodes will be connected and also the anodes. Here the 2 leds of the 15 led series are connected anode/cathode/anode/cathode

    Magnifying light voltages

    Hi Martin Yeah, as I recall the voltages went even higher. Please ignore my + and - on the board. Was trying to make sense of what was going on

    Magnifying light voltages

    I reached a dead end road with not being able to figure why R1 won't give me the required voltage drop. So trying a different tack. Found an old workshop light driven by NiMh batteries ( long dead). I want to transpose those leds to my light. Photo of old light with new ring for magnifying...

    Magnifying light voltages

    I think there are differences between ours. R1 by me green/brown/yellow not green/blue yellow Have now pulled C4 to have a good look at it
