Do you remember that good old board game operation ?
I do and its still as fun as it was when I was 8 years old.
I really do have to give credit to a co-worker / friend for this idea. One day out of the blue he walked up to me with this horrible grin that he gets when he has an awesome idea, all he says to me is "Shockeration" then walks away. I sit there flabbergasted for about 10 minutes walk over to his desk and ask "What do you mean Shockeration?" he responds with "You know operation? Think operation that shocks you instead of lighting up the light!" And here is what materialized out of the horrible idea.
There are videos of Shockeration on the last page!
This project is dangerous, we have taken steps to ensure safety with this version of the game.
Teachers! Did you use this instructable in your classroom?
Add a Teacher Note to share how you incorporated it into your lesson.
Step 1: Materials / Tools Required
2 x AAA Batteries
1 x Operation board game
1 x Camera Flash Circuit without capacitor
1 x Assorted Wire
1 x Wrist Strap
1 x Solder
1 x Thread
1 x Assorted Heat Shrink
6 x Phillip's Screws
5 inch solder-wick
1 x Soldering Station
1 x Wire Cutter
1 x Utility Knife
1 x Tweezers you don't care about
1 x Phillip's Screwdriver
Step 2: Pre-pair the Wrist Strap
1. Get a length of wire about 3 feet long strip about 1/2 an inch of shielding off of it
2. Cut a small hole in your wrist strap
3. The stripped wire is fed through the hole in the wrist strap.
4. Split the conductor in half and solder it to the center of the solder-wick
5. Sew the solder-wick and wire into the wrist strap.
6. For safety reasons use some heat shrink or string to connect the tweezers you don't care about to the wrist strap.
As you can see in the photos I used wire cover to make it look good as well as connect the tweezers to the wrist strap. This isn't required, just looks pretty good.
The Solder wick sewn into the wrist strap is the ground plane and you are connecting the tweezers to the wrist strap so that the stock only travels through your fingers to the wrist strap. Make sure you use the tweezers in the same hand as the wrist strap. If this electrical current were to go through your heart it could stop your heart. If you have never noticed all the commercially purchasable shocking products do the same thing.
Step 3: Pre-pair the Photo Flash Circuit
I purchased 20 Photo Flash charge Circuits from Electronics goldmine. Here are the instructions to pre-pair my model of photo flash circuit for this project. Electronics goldmine no longer sells my version of the photo flash circuit but here is another circuit that they sell. http://www.goldmine-elec-products.com/prodinfo.asp?number=G19047
1. Remove the Green, Blue, and Yellow Wires.
2. Remove the Neon Bulb that shows when the flash circuit is fully charged.
3. Solder the pads beside each other together.
4. Solder a 100pF to 1nF capacitor to the heads of were the Neon Bulb was, this capacitor needs to be a ceramic or Mylar film capacitor and should be rated to 400 volts.
You are using an extremely low capacitance capacitor to limit how much current can discharge into the player of the game. DO NOT use a larger capacitor. Also if your capacitor isn't rated for 400 volts, when it becomes overcharged it could explode. I have used a ton of this flash circuit and I know its maximum output voltage is 400 volts at less then 1 micro-amp. If you don't know how electronics function this project ISN'T SAFE FOR YOU.
Step 4: Pre-Pair the Operation Board Game and Assemble the Other Pieces.
1. There are 6 melted plastic pieces holding the cardboard layer down. You need to cut them off.
2. Remove the cardboard and you'll see the brains are in an easily removable gray piece of plastic. This grey piece is held in by three clips.
3. The Grey piece has all the electronics. Remove the 6 Phillip's screws, the cover will come off now.
4. Remove the 2 Phillip's screws holding each of the circuit boards down.
5. Clip the yellow wire that is connected you want to leave it connected to the metal piece attached to the grey plastic.
6. Cut the 4 wires that connect to the battery terminals, but make sure you leave the battery terminals intact.
7. Once all the electronics have been removed you'll have to modify the case a little bit. This is required to fit the photo flash circuit into the grey electronics case.
8. Cut the Switch Board in half, discard the half with the epoxy covered chip.
9. Solder the red positive wire to the switch in the same way as the photo.
10. Solder a second wire from the other position on the switch this is to connect to the battery terminals.
11. Because our photo flash circuit uses around 2.5 to 3.5 volts we are only going to use two AAA batteries, you will need to modify the grey case again. On the bottom you will need to remove the two metal battery connectors near the CE Symbol then install the connector like the photo.
12. Solder the Red wire from the Switch to the positive battery terminal. And solder the black wire from the flash circuit to the negative battery terminal. See the photo for reference.
13. Now solder the small yellow wire connected to the metal piece to the diode on the end of the flash circuit. See photo for reference. Also solder the wrist strap wire to the flash circuit again see photo for reference. (The Thick wire is the wrist strap and the thin wire is the wire that connects to the metal piece. Sorry I didn't mean to use yellow for both.)
14. Install the rest of the electronics (switch board and flash circuit into the case and close it. Re-Install the 6 Phillip's screws.
15. Pop the grey case back into the operation frame.
16. Re-install the card board and find appropriate screws to hold it down.
17. Flip it over and Install the 2 AAA Batteries and get ready to play Shockeration!!!
Step 5: Ending
I will be adding some youtube videos of the unit in action before April 1st!
