Step 8: Dummy Controls

The dummy chair was controlled by an Arduino micro controller. It was set up so when a button on the wall was pressed, it would initiate a cycle. Once the cycle started it powered the jig saw so the dummy would shake back and forth. The Arduino was also connected to the lights in the room. I used incubators lights that had a nice wire grid protective cover on them. Inside the lights I put Edison style light bulbs. When the button was pressed the lights would flicker on and off to simulate the current draw it would take to electrocute my victim. The last effect triggered by the button press was the eyes of the dummy would glow. Each eye would flicker on and off independently in a nice eerie blue color. After the cycle was complete the saw would stop, the lights would come back on, and the eyes would slowly fade to off as if the electricity was leaving the corpse.

I took two videos showing the sequences, unfortuatley the phone I used to take the video didn't do well in the low light situations. So for the second video I added extra light, not as spooky, but that way you can see what is going on. For some added ambiance, I also built a pseudo fence to divide the room and make it look more like a prison. You can see the fence in the video.

<p>disgusting !!!!!</p>
This is so creepy and realistic...awesome job.
could i use the zapper pens to make it really electrolyte some one just enough to make them jump
Air blasts work just as well and no one can say you were trying to electrocute them. <br>
i think it be fun to hook a lilltle zappers like the pens and a metal plate for these
Great job, one can see that a lot of work went into building the cool looking chairs. The special effects were amazing not only with the dummy chair but also on the interactive chair for the party guests. The attention to details of the electric chairs design and construction is really neat. To get the full effect of how great this project was, one would need to be present for the thrilling experience of sitting in the chair.
When I first saw this, I thought you were putting pumpkins on the dummies and pumping high voltage through them to see which one would blow up first
I love the level of detail achieved on this project. Great write up, loved reading it. It wasn't a snoozer. Very realistic--not cheesy. Outstanding overall on everything!!
Very cool. I think you should leave it up for the holidays, add some twinkle lights and have a Jack Skellington Christmas tree.
I thought about bringing it into work and using it for my desk chair. It is quite comfortable for me since all the measurements for it are based off my body.
sweet looking chairs ! Thank you for sharing
Having had the opportunity to take the ride on this chair, I can say that it was truly a great effect. ksykes did an amazing job!
Good job, and I like the detail work!
Could maybe use a little bit of smoke coming out of the victim, but apart from that AWESOME :) Also those blood stains will make a nice feature when you ever sell your house ... WTF happened here ..... :-)
I thought about a fog machine, but the one I have would have smoked up the whole basement after a couple runs. There isn't a lot of air circulation down there. It was pretty funny taking the cable installation tech down into the basement. All the decorations were put away, so it was just a normal basement with blood all over the walls and floors :D
A truly sick mind...<br><br><sub><sub>...I love it!</sub></sub>
