DIY Magnetic stirrer for e-juice / e-liquid mixer
One of my first attempt to steep the e-juice quicker is using the magnetic stirrer to mix/blend the ingredients - it took me a heck of time and effort how to get this done especially the materials to stick the magnet on the fan holder and the magnetic stir. So I've recalled my useless USB fan and CD-ROM drive. This is how it finally done - the motor is quite fast but it make some sound due to the imperfect shape of the piece of wood where the magnet is sticking to. Anyway it's usable - moving forward i try to make the fan speed adjustable/variable so that it can mix the juice gracefully instead of vigorous like now.
One simple circuit to step up voltage using LM2577 -Adj P+ chip. The schematic is from Texas Instrument and it works expected - and below is...
