Make Your Own Stir Plate: 3D Printed Stir Plate Magnet Mounting-Thingy!

3D Printed Stir Plate

In my quest to build a stir plate using a computer cooling type fan, I found that the most difficult part of getting that to work well was mounting the magnets properly.  I settled on two magnets and in spite of several attempts I was unable to get an efficient (or even stable) mount for the magnets.  Magnet alignment is an important part of stir plate design.  Uneven or mis-spaced magnets mean easily thrown stir bars and poor performance.

I decided to design and print a 3D printed mounting aid to make magnet mounting easier and more precise.  I’ve since dubbed this the HBF Stir Plate Mounting-Thingy.  In my opinion, it turned out pretty amazing.

High Temp Food Grade Pump – 12V, 108 GPH – $30 + Free Shipping

High temperature(100'C) 6.8L/Min (108GPH) mini DC12V Water Pump. Food grade. Sous V

High temperature food safe pump.  108 Gallons per hour transfer rate.  High temperature up to 100 deg C.  Note that this is 12V DC.  You need to wire this up to a compatible power supply.

In my opinion this is not a direct one to one replacement for something like a Chugger Pump or a March Pump – the flow rate just isn’t there.  I do see some possible homebrewing applications including… Transferring wort, mash or sparge water within your system, recirculating mash to help keep a consistent temperature and recirculating wort for chilling.

Stainless Carbonation Cap [+2 orings] – PET Bottles + Draft Line Cleaning Builds

Hombrew soft drink PET Bottle Filling Stainless Steel Carbonation / Line Cleaning Cap w/ 5/16" Barb/ Drop with two free O-ring

Stainless steel ball lock carbonation cap with barb.  Includes two replacement o-rings.

PET Bottles as Growlers: These are generally intended to convert 1L and 2L bottles to growlers.  Fill up a 1L or 2L PET bottle with your favorite homebrew.  Put one of these on (purge the headspace by squeezing if you want to) and then pressurize for transport.  This should help to reduce oxygen pickup and maintain carbonation levels.

Fine tune or rapidly carbonate beer: You can also use this cap to rapidly carbonate beer.  Same process as for transport, just set your regulator to the proper pressure and shake or agitate the PET bottle to help introduce CO2.  Or hook it up to CO2 and let it sit in you kegerator.

Note, from the product description: “The post on this unique carbonation cap has been machined ,so it fit BOTH the liquid and gas ball lock disconnects.” – that’s a great thing in my opinion as it makes the projects below possible – please check the current product description for currentness

Dual Display Digital LCD Thermometer [Monitor Kegerator & Ferm Temps] – $14.99

DROK -20 to +100℃ Digital Thermometer, DC 4-28V Indoor Outdoor Thermometer with Dual LED Display, High Accuracy Digital Temperature Gauge Tester with 2 Waterproof NTC Temperature Sensor ProbeDROK -20 to +100℃ Digital Thermometer, DC 4-28V Indoor Outdoor Thermometer with Dual LED Display, High Accuracy Digital Temperature Gauge Tester with 2 Waterproof NTC Temperature Sensor Probe

Possible uses include monitoring kegerator temperatures, beer fridge temperatures and fermentation chamber/area temperatures.  Since it displays two temps you could monitor both your kegerator AND fermentation chamber.

Note that this thermometer does not use batteries and needs to be wired to an appropriate power supply.  Something that provides DC 4-28V.  The probes are waterproof, but I’m seeing where they are food safe.  It appears this displays in deg C only.
