This is a pretty simple Infrared Harp. The sensors work like on/off switches to trigger various sounds when they are plugged into your computer's music program. With the MidiTron you can use any type of analog or digital input device, from temperature sensors to regular switches, to trigger your sounds. Get creative, it's really fun to think about all the things you could play!
- 8 - 10 Infrared Sensors
- 22- 24 gauge wire in red, black, and yellow
- Needle nose pliers
- MIDI to USB converter
- Two 4 - 6' aluminum u- channels
- Two 4 - 6' of 2 x 4 wood
- Large SPST On/Off Switch
- Wood Screws
- Stepper drill bit for drilling through metal
- Zip ties (small)
- Zip tie mounts
- Wire Butt Connectors (small 26 - 24)
- Crimper for the connectors
- Multimeter for testing connections
- 9V 300mA power supply with connector
- Solderless Breadboard
- Box of jumper wires
- Jewelry screwdriver set
- Music software like Garage Band
- MidiTron Software
- USB Driver software
Step 1: Test the Infrared Sensors
Place the wires from the sensors into the corresponding channels of the breadboard. Use jumper wires to connect the yellow wires to the MidiTron. Now connect the power supply to the MidiTron. Then, using a jumper wires, connect the MidiTron to the vertical channel of your breadboard.
Step 2: Set Up Your Miditron
Step 3: Prepare the U-Channel
Step 4: Complete the Wiring
Use zip ties to tuck the wires tucked away, but leave enough slack so they don't pull out of the IR sensors. Use your multi-meter to test the connections. Once it's working, disconnect the wires.
Step 5: Anchor Harp and MidiTron to the Wall
Screw in your U-channel with the IR sensors facing downward to the top 2 x 4. Screw in the bottom U-channel to the bottom 2 x 4. Now anchor your Miditron to the wall. We hid ours under a tambourine. Then cut and strip your wires, so they reach the MidiTron, Leave slack so they don't pull out of the sensors.
Infra-red sensors know exactly where your hands are, and you can digitize any kind of music.
So now you can start composing your off-the-wall symphony!
