    Closed loop for two brushless motors

    Not really a suitable project for someone who is a 'total noob to Electronics'?

    Lots of 555 PWM circuits out there.

    Home brewing fermentation monitoring

    Normally things don't happen that fast when brewing, I brew both beer & wine and usually take a SG reading & and a visual check to gauge when to rack. It's not that a precise science.

    Home brewing fermentation monitoring

    One way around getting over the possible rotation of the air lifted float type, would be to place the button magnet on the top of the float, and use the S4xx sensor on the lid cover. You can get really small button mag.

    Home brewing fermentation monitoring

    You could use a small button magnet attached to the float, (what kind do you have)? A Honeywell S4xx sensor would detect the movement. One problem may be if there is significant evaporation of the air lock liquid. Another issue there is if the float happens to rotate!

    Sunbeam Electric Bedspread stopped heating. Anyone know what the element resistance should be?

    Have you seen this post on similar make/issues? https://maker.pro/forums/threads/sunbeam-electric-blanket-no-heat.281560/ I see that you did, no info there that helps?

    Sunbeam Electric Bedspread stopped heating. Anyone know what the element resistance should be?

    Plug it in and trace the voltage, see it it ends up on the element connectors.

    MOTOR DRIVE 48 VOLT .

    What are the details of the motor? , can it be started other than full-on?, IOW ramp the speed up. What is the nature of the load?

    Reversing AC motor

    Looks like a nice job! Do you have any plans for it?

    Reversing AC motor

    Here is a simple DWG, the M (motor) would represent one of the windings, the other stays connected the same way., always stop before reversing. This is for a simple DC motor but the switch action is the same for one winding.

    Reversing AC motor

    OK then you just need to reverse one or the other windings. One winding remains the same connection.

    Reversing AC motor

    IF it is a PSC, Permanent Start Cap motor, all you need is a SPDT switch in order to reverse. Measure both windings, if they are the same then it is PSC and I can post you a simple DWG.

    limiting a heating element in a water heater?

    What type of heating element is it? Rod immersion type? It may have been more economical to obtain a immersion style with the thermostat pocket fitted. Fitting a separate one afterwards can be costly.

    limiting a heating element in a water heater?

    What type of water heater is it? All the ones I have been involved in has a thermostat fitted for safety reasons, if nothing else.

    Need help specifying certain motor

    If this is a non-positioning application but variable speed is reqd, , ex-treadmill DC motors may work, they are 2hp -3.5hp. There are the MC2100 controllers also, one source is T.M.s that often come up locally, Free for Pickup (not working). .

    Schematic Question

    Very similar in practice to bi-polar electrolytic capacitors used in AC motor starting, where a very large capacitance value is required in order to provide the initial starting current.

    Missing capacitor for bench grinder

    Ensure it is motor capacitor run rated, and stay away from Chinese origin versions. Mouser sells N.A. made versions.
