RandomMachine “RAMA”
RandomMachine
RAMA is a device, that uses uranium glass and a Geiger counter to create a true random generator. The idea comes from Jayson a student friend of mine. I re-created this idea in a compact form with extended use for FoxDot (Musical live-coding environment). The Arduino sends time delays between each measured knocked-off electron (ionization). This delay can be used e.g. as duration of a note played by a synth in FoxDot.
RandomMachine used with FoxDot
| 1. Components |
|---|
 |
| 1 x Arduino Micro |
| 1 x MAX9814 Microphone Sound sensor |
| 1 x DIY Geiger Counter Parts Kit Modul Nuclear Radiation Detector F3K3 |
| 1 x On/Off switch |
| Wires |
| 1 x Piece of Uranium glass |
| 2. Print Case Parts (Scale parts by 2% to include shrinking rate) |
|---|
 |
 |
| 3. Assembling |
|---|
 |
| 1. Assemble D.I.Y. Kit of Geiger counter |
| Do not solder audio jack socket, Piezo buzzer, and D23 LED onto board! |
| Optional: Replace switch of kit with a bigger version. In this case do not solder the switch to the board either |
| 2. Use wires between Piezo buzzer and glue microphone module and piezo buzzer together |
| 3. Drill holes in case to connect wires |
| 4. Use wires between Geiger Board (D 23) and LED light glued into case |
| 5. Geiger Counter Breakout connector +/- >> Arduino 5V/GND |
| 6. Sound Sensor AUD >> Arduino A2 |
| 7. Sound Sensor + >> Arduino 5V |
| 8. Sound Sensor - >> Arduino GND |
| 9. Connect Arduino to Computer and upload randomMachine.ino |
How does it work?
-
Connect device to your laptop/PC and switch it on
-
Use case 1: Just run RandomMachine.py from your terminal >> This will print duration into your console
-
Use case 2: Import class from RandomMachine.py into your program and use read() function as value
-
Use case 3: Install the RandomMachine.py in your FoxDot installation to use it for music making (Video above). Follow instruction at same place on GitLab
