    picking components for a stir plate

    for what its worth, I was finally able to dig up some posts about what I'm wanting to do that were specific about the components used. It seems 9V DC is preferred as the 12 volt power supplys seem to be just a touch too much. The pots used are 25 Ohms 3 watt

    picking components for a stir plate

    oh, since soldering really isn't my thing, could get this and cut the wires and re-attach a pot I preferred right? Would I still be looking at the same requirements of a 1-3 watt pot?

    I see what was meant by using a PWM now. Thank you for the example. Ya it does seem like those would be more ideal. I just with I could find one where the knob had a longer shank and securing nut that could go through the wooden box I'm working with.

    Or should I be using a Rheostat? The purpose is to control the RPMs of the fan.

    picking components for a stir plate

    I'm wanting to build a stir plate to grow yeast for home brewing. If you want to know what it is or how it works, you can check this out. But it is not necessary. In a nutshell, I need to get some DC power (12V, 1 - 2 amps), and send it to a switch, then a potentiometer, then to a regular...

    Greetings, from Texas.

    Hello friends, and fellow hobbyists! Greeting to you from the land of bluebonnets. I don't know much about electronics, and that's why I'm here. I'm kind of a jack of all trades, and I love biology. And good craft beer. And that is actually what brought me here.
