    Hegner Scroll Saw - Motor speed control issue

    I would Ohmmit that last part. when you set your multimeter to ohms (resistance measurement) & your probes to an AC source, the internal voltage source used for resistance measurements can interact dangerously with the live AC voltage, potentially causing a circuit overload or blowing the...

    Triggering a passive infrared sensor?

    I can’t answer your question without more information :( Make, model, schematic? What is your application?

    Triggering a passive infrared sensor?

    Like I did last time…I got the specifications of my aunts PIR system; voltage,current requirements (power ground & signal triggering). Went shopping and found out. They were almost identical,a direct swap! pin for pin replacement.. Passive infrared sensors detect the change in infrared radiation...

    Draper led torch charging light remains on

    I believe you. That the power supply plugged in to charge the battery was a higher current and voltage then the charger that came with your flashlight.Heat is generated on the PCB board, which could have melted the solder to a poorly connected wire, which is making contact with the led...

    Adruino connection question

    Use the analog pins A0 & A1 of your Arduino for the two input leads of your guitar distortion pedal or fuzz box.

    Adruino connection question

    No! You are overdriving and clipping that’s how you get your distortion. I envision your loss of vision, which is a good thing because now you can use your ears and if you’re horrible at playing the guitar, I can see why distortion would help.. You’re running the operational amplifier at half 9...

    Draper led torch charging light remains on

    Excellent, thank you. If it’s possible? Could you snap another picture of the underside of that board? Thanks again.

    Draper led torch charging light remains on

    Yes. Yes. No. You’re going to have to open it up and take a photo of the PCB board.

    Viewsonic VX3276-2K-mhd monitor Power failure

    Belated welcome to Maker Pro. Turn off the monitor, unplug the power cord then plug it back in. Turn on the monitor and do a factory reset see if that helps. Do you know how to solder and use a multimeter? You could be the one who solves this problem for someone else. You took it apart to take...

    Filters Common Mode Ckoke

    Welcome to Maker Pro. :) You’re going to need an inductance meter along with a capacitance meter. Measure the inductance and capacitance and plug them in to the formula provided below that will give you your cut off frequency for you’re soon to be known value of common mode choke. It looks like...

    RGBIC/WS2811/WS2815 consumption in off mode.

    I completely understand what you are asking. Apologies; I simply do not know. :(

    RGBIC/WS2811/WS2815 consumption in off mode.

    Adding a switch is one solution I might add you are very observant that leaves me as a disadvantage because I do not know your application and I myself don’t want to do 100 questions tonight. Maybe 200 questions that’s why I’m here :)

    RGBIC/WS2811/WS2815 consumption in off mode.

    That is a totally different question and I do have an answer for you. The LED’s themselves have a quiescent current 2.1 mA. That is an order of magnitude increase, then the controller.Page 3 of 8 pages. This is why data sheets are so important and the first thing you should research, or present...
