Electromagnetic Floater

Step 2 Prepare The Base

Once the materials are gathered, the cases needs to be prepared. For my base I used a project box from The Source (Radio Shack in U.S.) to house the electronics, and a ring box to house the magnets and sensor assembly.

First you need to drill a hole in the back of each box for the support wire to go through. Also cut holes for the power switch, power input, set height button and LED indicator. You also need to cut most of the bottom of the ring box out, just leaving a lip on the bottom.

Support the ring box above the base box by using some heavy gauge steel wire, bent to the shape and height you want. Next, wrap the electrical wire around the steel wire, then cover all of it with the vinyl tubing (optional) as seen below.

Next, bend the bottom end of the support in a zig zag pattern and use hot glue to secure it to the inside of the bottom case (see second picture below). I secured the ring box to the top of the support wire by using a magnet, but it could also stuck on by hot glue.

It is not clear to me why two coils are used or how the IR sensing works The collector of the NPN transistor is supposed to be connected to VCC2 on motor driver circuit, where is that? It looks to me like there's an error in the circuit as the emitter seems to be connected to +12 and the base to +5. Why are two transistors shown in the pictures and only one in the circuit? Or is one of the "transistors" in the pictures a voltage regulator? Would love to try this project please let me know asap. thanks
