“1.1 What is it
When I was a child I had a game like an electric puzzle that fascinated me. With that game, you could make a lot of electric circuits like radio, buzzer sounds, lights…and others. This project is not like that game but is something close.I wanted to buy such a game but you don’t find such games these days. So first I want to show you what this game can do so you can decide if you want it or not.
This is a puzzle-like game where the puzzle pieces are electronic components.
I made 19 circuits using simple passive electronic components.
The electronic components are making contact without soldering anything, contact is made by small magnets with screws.
The game can be used especially for educational purposes.
1.2 What will you be able to do
Implemented circuits are:
- Voltmeter- measuring a battery voltage - video hereUsing a LED, a switch, a push-button, a REED switch, and making a variable LED light
- Capacitor discharge - video hereLight a LED with water
- Infrared remote control
- Infrared remote with a transistor as a switch
- Simple buzzer circuit
- Variable buzzer sounds
- Discharge capacitor into the buzzer
- Birds sound with a buzzer
- Light-activated LED
- Dark activated LED
- Touch sensor
- DC motor and Newton’s disk
- DC motor speed regulator
- Generating electricity with a DC motor
- Flip flop LED
- Tesla coil
- Lie detector
1.3 Tools that do you need
- tweezers
- soft hammer (a hammer that is not made out of metal, maybe a wood hammer - I used a hammer with plastic head, you can see an image in step 1)
- pliers to cut wires
- striping pliers
- electric screwdriver (don’t even try to do this manually)
- soldering iron
- palette knife
- 3D printer
- a measuring device (for continuity, ohmmeter, transistors…)
Supplies:1.4 Materials that you need
- PETG filament for the 3D printer(I used red and blue but the choice is yours). I don’t think PLA will work well for this. You will need a small amount of red, transparent PETG for the leds that are completely inside the covers. I used ruby red.
