My son's school has a haunted house every year. This year I built an electric chair for it. It went over really well. The look on the principal's face was priceless when he sat in it and it turned on Smile

Love the electric chair. My co-workers and I are planning a build for Halloween this year. We really like the IR beam and the light dimming. Can you provide some information on the wiring and parts used for this chair for us since we are not savvy on the electrical work.

Thank You

Not the most elegant solution, but I used parts I had laying around.

I started with an infrared door minder kit -> http://www.alltronics.com/cgi-bin/item/KIT_130/search/Infrared-Barrier-Door-Minder-Kit

I did not mount the IR Sender or Receiver on the boards, but instead soldered leads to them and mounted them in the arms of the chair and mounted the boards under the chair with all the other electronics.

The infrared door minder has a relay with NO & NC outputs. I fed this relay with a 12v wall wart and ran the two outputs to two solid state power relays.
Both of these relays where fed with 120Vac. The output of the relay fed by the NC went to the outlet on the back of the chair for the room lighting. The output of the relay fed by the NO went to a power strip that fed the orbital sander, strobe lights, and air solenoid.

Hopefully my description makes it clear, if not let me know.

It all sounds good in my head, but I wouldn't know where to begin when it came to wiring this thing up. I know very little about electrical and when I tried soldering a board together for another project, it never worked correctly so I gave up on it.

That is nice! I was actually expecting it to be kind of a prank chair. A lil zap like we used to do in highschool. Great chair.
