    Arrived yeasterday - working tonight. Excellent for the price. May need to improve the case. For others I have included a picture of the hall effect sensor installation. Not easy to see, it has a dot along side one pin which aligns to the dot on the circuit board. Also it sits in the hole so it is flush with the board. Or look at the "G" orientation. What worked for me was the nut at the bottom and the soldered side facing the magnet. Make sure to cover the solder/wires with some tape or hot gun glue, otherwise the magnet may short the pads. I have also included a picture of my working pot position. I held the magnet in place while adjusting the pot and you feel/hear light buzzing when near the correct setting.

    The package arrived with the upright support cracked into two pieces and the base support with cracks but no separation. I glued the upright support together with the superglue supplied in the kit. The pcb is well made and the parts values are clearly marked. I measured each resistor before soldering. The instructions are nearly useless. Roly3 gave valuable information. You must get the magnet polarities correct. You can easily reverse the electromagnet connector to try the other polarity. Hold the permanent magnet near the electromagnet and carefully adjust the potentiometer. You will feel a slight vibration when you get close to the correct setting. Very carefully adjust the potentiometer until the magnet floats. It takes a lot of patience. It it does not work, try reversing the polarity. I routed each wire from the electromagnet through the holes in the plastic component. I placed a small piece of shrink tubing over one connection and then a larger piece over both to provide mechanical support to the wires.
