DIY Kalk Reactor

updates:

weakness in the design, as you can see in the previous pics, the fan is enclosed in a box, and because the fan is pointing downwards it is affecting the efficiency of the fan because it tries to draw air when there's not much air under the black acrylic. need to do some tweaking on that aspect.

You can solve it by cutting off the fan blades or reducing their angle so that they no longer draw air, just rotate...

tried cutting it but the blades metal and my cutter can't make it. i'll try the straightening approach. thanks bro

can try heating the blade up with a lighter then twisting it...

design update:

have installed my set already for 2 days now. but for anybody considering to DIY one, please note that you're magnet must be strong enough so that you could set the speed a bit higher. because by reducing the voltage going in to the fan, it's also losing power and sometimes it doesn't turn, so i reduced the frequency of the mixing when there is somebody around to check until I sort out the design flow.

I think it's better to reduce speed by mechanical means (i.e gears) rather than reducing the power
