Deez DIY Magnetic Stirrer

in all honesty.. what is wrong with using a handheld coffee/mil frother?

I'm genuinely asking..
Nothing wrong, I think the purpose was just to be able to make something out of Items you already have lying around. If you have a frother I guess you would not need this? I personally like a stirrer better coz I made it :D

What @Dietz said. Also, some people like to leave mixes to stir for long. I personally leave mine to stir for 3 hours when I make a big batch. Aint no way I'm standing with a frother for 3 hours.

I've tried this and it does not work. Well, it does work for a short while but then the milk frother packs up because the VG is too thick for it to run properly. This happened with 2 milk frothers I bought specifically for this purpose, different brands.

Why leave it for so long?

also, what did you make the stir rod from? and its it coated? or did you just buy one?

I've noticed that it takes a while for all the constituents to mix with each other, with the flavour concentrates sitting mostly at the top. So I just let it do its thing for 3 hours with no real science behind it.
Bought the rod at Blck Vapor. It's coated.
 
Bad part about a top mount is vibration might let contaminating particles fall in.
Bottom stirrer can be closed and left alone while working.
 
- A "speed switch" is called a potentiometer, or "pot" for short. The one you require will be based largely on your chosen fan and power source.

After recent events, if I walk into a store now and ask for "pot" I might get something totally different... On the other hand, after use I might not mind if my juice was stirred or not, lol.
 
Thanks @veecee, that look good. Thats exactly what I am planning to build it into from this, add a heating pad and get some bigger stirrer bars

@ Dietz thank you for the awesome info. I followed your design with the exception of the pot control module. I was able to get a away with a simple switched 10K potentiometer that works fine for me.

The hardest part was getting the right magnets. Hard drive magnets seemed to produce the best results. I used a cheap electrical 60mmx60mm enclosure to house everything. The size is really compact and the components fit in with hardly any room left. Should have went bigger on the enclosure but for now I am happy with it. I tried this as it was with 80/20 VG PG juices and it just wouldn't mix properly.

After some thinking, I wanted to add heating function to heat VG to improve the viscosity to aid the mixing process so I searched around internationally on a few popular websites and manage to get a 12V Silicon Heating Pad (normally used for 3D printing) which is about 10W. Also I needed to control the temperature. So I managed to get a 12V temp controller on the cheap also for about R65.00

Bought them from here:

I couldn't fit the temp controller flush mount due to the lack of space available in the enclosure so I just glued it to the outside. Not the best looking job but it works. The temp controller is easy to setup although the chinglish instructions are downright useless so I had to follow a process of trial and error.

The silicone heating pad reaches 110 degrees Celsius so temperature control is important not to damage your nicotine your mixes. I used a cheap thermocouple thermometer to do my initial setup and calibration of the temp controller (also available from supplier listed above below R100).

With some fine tuning, I have managed to get a temp range of the liquid content inside the beaker to be around min 40 to max 41 degrees Celsius (don't be misled with the picture as it shows 50-60 degrees on the display which is only the heating pad temp)

Now I just need to add a small piece of 0.5mm aluminium sheet over the silicone heat pad to allow better thermal conductivity and to improve the ramp up time. Will get to this over the weekend.

All in all, I am happy with the results. The stirrer is silent, heats up in about 5 minutes and seems to be creating a decent vortex.

Here's a video clip of the stirrer it in action :)

Wow, Now THAT is a DIY MAgnetic Stirrer!!!!
Very Well done on this!! I appreciate your feedback and Notes on this Master Stirrer ;);) And it Looks Friggen Cool with your front control and LED too!

The only updates that Ive done with mine was to rebuild it into the same electrical box as you used, im thinking Its time for another upgrade so that I too have heat on mine :cool::cool:

Happy mixing and thanks again for Sharing, if there was a prize for this, it would definitely go to you!

Agreed. That's kickass! Exactly the upgrades that my stirrer needs!
