Hand Eye Coordination Game--Wire Loop Game

A wire loop game is a game which involves guiding a metal loop along a serpentine length of wire without actually touching the loop to the wire. The loop and wire are connected to a power source in such a way that, if they touch, they form a closed electric circuit. The circuit includes a light- or sound-emitting device of some form, which indicates that the game has been lost.

Step 1: Things You Need

Scrap piece of wooden block & some sticks

Chisel & malletfor wood working

Stiff copper wire or any conducting stiff wire will do the work

Copper clad board

Soldering kit

PCB etchant - ferric chloride

Isopropyl alcohol
Permanent marker
SCR - c106d (Silicon-controlled rectifier)
Push to make switch
Piezo buzzer
40k ohms resistor
5mm LED
9v battery with snap
Wires

Step 2: Make Two Chiselled Slots for the Wooden Stick

Step 3: Insert the Sticks and Use Your Mallet

Step 4: Connect the Stiff Wires Across the Wooden Sticks With Any Pattern

Step 5: Make a Loop

Step 6: Circuit (Important : See the Note Added to the Circuit)

Step 7: Clean the Copper Clad Board With IPA and Draw the Circuit With Permanent Marker

Or Use a laser print out and transfer the toner. Find the circuit wizard file to get the layout

Step 8: Dissolve the Etchant in Water. (HINT : Stronger the Solution Quicker the Etching Process)

Step 9: Let the Board Take Bath to Get Rid of Exposed Copper

Step 10: After Getting Rid of Exposed Copper. Give a Water Bath to the Board

Step 11: Wipe Off the Traces of Permanent Marker Using IPA

Step 12: Hold the Etched Board Against the Light to Find the Traces of Copper

Step 13: Mark N Drill Holes

Step 14: Fix the Components in Octopus. Check the Link for Build Instructions -->> Octopus

Step 15: Tin the Tip

Step 16: Apply Flux

Step 17: Solder

Step 18: Cut the Excess

Step 19: Remove the Excess Flux With IPA or It Will Corrode the Circuit

Step 20: Connect the Buzzer, Wire & Loop to the PCB and Solder / Secure the PCB With Hot Glue

Step 21: Insulate the End Points

Step 22: That's It. How to Play??

Start from one end without touching the wire reach the other end. If buzzer rings you've failed the task. Press the reset button and start over. Most important -->> Don't cheat like Mr.Bean that's why I never included the switch. Enjoy and test your hands.
