Episode 18: The Self Playing Harmonica

Episode 18: The Self Playing Harmonica
There are lots of different types of Self-Playing Instruments, but we here at Stupid Inventions wanted to create something new!

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 Printer
1x Vacuum Cleaner
1x Harmonica
Tape, Scissors, Sharp Knife, and a computer.

Step 1Preparing The Printer

Preparing The Printer
This step will vary based on the printer and harmonica your using.

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

Instead of putting solenoids, blowers, dryers etc... why don't you just use your plain old mouth.....you just might end up playing the harmonica better !!

If you like to play the Harmonica that way...so be it !

This is not a STUPID Invention!. Very clever.

I am doing it, I want to play the Beto's Ninth Symphony. But in black and white only, because my printer hasn't color ink.

Doesn't everything?

LOL love the sunnies and hat. They just give it so much more character

The stepper motor moves so it plays Ode to Joy!

There is nothing wrong with the music being made by this invention... It is the demands of inappeasable ( my spell checker chose this word :P) listeners that are expressed here... don't listen to them, just rock on and enjoy the rich variation that creativity can bring to music. It SHOULD sound like nothing else ever heard before. Good one!

Are we referring to the comment trolls on hackaday, perhaps? Those guys are brutal (and yet, have yet to prove that they've built anything of value themselves...)

I don't know about that site, but I did retire from a very exciting idea group, due to the "it'll never work" mentality. Wonder why pop music still uses the same three chords Beethoven used? Do they all eat the same food every day? For me, originality is essential to good music. On the other hand, all original ideas may not work so well! I really liked the printer's music!

Heh, if you get a chance, do a bit of research into how many times Pachelbel's Canon appears in pop music!

EDIT: I did the work for you, when I was looking up how to properly spell "Pachelbel." Link: http://en.wikipedia.org/wiki/Rob_Paravonian#Pachelbel_Rant

Good start but needs work, obviously. I'm sure you're aware that a harmonica has in and out reeds every other note meaning that you need to reverse airflow rapidly to get it to play all its available notes. A vacuum cleaner is clearly one direction only, and overkill at that. Good luck refining this project into somethiing that can actually play a tune.

Your results so far are good, and it's an interesting project. Except for the programming function, you've essentially followed the path automaton makers did over 100 years ago, and the printer takes care of most of the mechanics. Regarding the hair blower idea,most hair blowers have a heat-off, blower-only function which would require little or no hacking, but it yours doesn't, disconnecting the heater element shouldn't be difficult.. Just be careful, because you'll be working with line-voltages. You could regulate the fan speed with an ordinary light dimmer (about $10 at a hardware store) as long as the heating element is not part of the circuit. A solenoid could also reverse the airflow direction on command from the computer/printer giving you the full range of notes in your harmonica. A bigger problem, though, is how to keep the noise from your air blower and printer from drowning out the relatively small sound the harmonica makes.
Sep 14, 2010. 10:22 AMjeff-o says:
Yeah, a solenoid to direct airflow is definitely what's needed. Something to rapidly turn on and off the airflow, since you can't spin up a blower motor fast enough.

yay a new way 2 bug the hell out of my parents!!! keep at it....

Awesome. When I saw the first pic, I imagined that you would interface with the printers stepper motor using a microprocessor etc - I thought it seemed like more work than fun... But your method of 'printing' the music using the existing windows print driver is simple and elegant - truly creative! :-)

5 stars!

I did. They do this weird thing where if only one person rates it 5, it won't actually be 5. I've always wanted to figure out how it works.

if you ever make one for a tuba or ukulele, contact me.

It has potential as an idea, but I'm not sure if it's evolved far enough to really be called a 'self-playing' harmonica, being that it's just moving air over the reeds in a static motion-there's no music being made, just a whole lot of noise. A fully-capable one would involve solenoids, air tubes to each reed on the harp, and a microprocessor, as well as the software to control it. At least, it sounds good on paper.
Aug 19, 2009. 10:07 PMguitarman63mm says:
Yes, yes I did laugh profusely. It's almost as goofy as Bleep Labs's noise-maker, the http://www.youtube.com/watch?v=UFaU6Euuytg&feature=channel_page!

In all seriousness, kudos on the idea. I've tried playing diatonic harps, but it always manifests itself into some sort of Bob Dylan-esque blow/draw game...
