Electric Chair Joule Thief

Step 4 The Negative Connection

Ok, we have a small wooden chair, and a rather intimidating looking death helmet, now for a few finishing steps.

To make the negative connection I used a small peice of metal from the side of a 9v battery that I disassembled previously. Make sure you grind away the label and any paint, then cut out a nice flat piece out of the side.

Grab your death chair and dremel or drill and drill a small hole in the middle of the seat of the chair. Slide the negative wire of the joule thief from the bottom through the top of the chair and solder the end to the middle of the plate of metal, then pull back to the metal is somewhat flush with the chair seat. I used some more white glue on the bottom, but it didn't seem to adhere.

Now before we hide the joule thief underneath the chair, flip to the back of the chair and drill three holes in the bottom trim, this is where I fed the positive and negative wires for the L.E.D. and the positive wire for the battery connection. I suggest you do the same.

Once complete, I crammed the joule thief under the chair, making sure the components fit within the sides of the trim, and grabbed a piece of scrap which I sanded and glued to the underside to keep everything in place.
