If you are searching for a way to bring your homebrewing to the next level, it is time to build a stir plate. A stir plate has one simple purpose…stir like a boss. There are plenty of commercial grade stir plates out there for $40-$200. That is nonsense and keeps you from enjoying the second best thing about homebrewing, building stuff.
To maximize yeast, it is essential to make a starter. This will help the yeast get a head start and ferment better and faster. If you have no idea what a yeast starter is, Google it and return to this page afterwards.
- A cigar box or project box
- A rare earth magnet from a hard drive
- PC cooling fan (these are everywhere)
- Universal AC/DC power adapter
- Super glue
- Craft beer to drink
- Electrician tape or Solder
- Rubber rings
- On/Off switch
- LED power light
- Stir Bar
- 1000ml or 2000ml Erlenmeyer Flask or A mason jar works as well
Here is a lame video that I made (after drinking three cans of Resin) showing the different parts and the wiring in my homemade stir plate. I am NOT an electrician and there is probably a better way to do the wiring. There are also way better stir plates out there you can buy or even make. Well, my plate works and it works damn good. That is all that matters.
If you did everything correct, it should fire up and function properly. Make sure the rheostat is not hot when you touch it. I made the mistake of crossing one wire incorrectly and it got very hot to the touch.
Good luck on your build and I hope my half assed tutorial helped!
