So we decided to build the Self Playing Harmonica!
Made from an old printer and a vacuum cleaner, the Self-Playing Harmonica will play different songs based on the image you print!
Watch the video to see it in action!
What you'll need to make this device:
1x Vacuum Cleaner
Tape, Scissors, Sharp Knife, and a computer.
Step 1: Preparing The Printer
Basically what you want to do is make sure there's enough room for the harmonica to be able to go from right to left while attached to the ink cartridges.
I didn't take a picture of the printer before I cut parts of it off, but you could see where the main cuts were. I only had to cut pieces of plastic in order to fit the harmonica, so the printer should work perfectly despite the cosmetic surgery...
Be careful with whatever knife or scissor you use to remove the plastic parts.
This is the only hard part to this Stupid Invention
Step 2: Adding The Harmonica
Just make sure its attached as securely as possible, and try not to cover up any of the air holes of the Harmonica.
Once attached, turn the printer on and give it a test run to make sure the printer can fully function even with all the modification.
Step 3: Adding The Vacuum Cleaner
I had to attach it to a weight to keep it sucking in the same spot.
Choosing where to place the nozzle is entirely up to you, but you may want it to be near the middle so you can be sure the complete harmonica will pass by the vacuum cleaner.
Step 4: Fine Tuning
Once everything is in place, the real fun part begins!
Try printing a few random images to see what sounds the Self Playing Harmonica will play.
Once you get a feel for the device, try "drawing a song" for it to play.
If I was more musically inclined I would have developed this further, but you can see in the picture the song that I drew. Watch the video in the first and last step to see the Self Playing Harmonica in action and hear what this song sounds like!
Note: I had to cut a piece of Printer Paper in half, so that the printer would still print and that the paper wouldn't interfere with the vacuum and the harmonica.
Step 5: The Self Playing Harmonica Is Complete!
Now you have a fully programmable Self-Playing Harmonica!
Try drawing different songs and see what plays!
P.S. I decided to decorate the Self-Playing Harmonica... consider it one of the Robot Blues Brothers...
