Ever thought of building a laser harp? If you can do Aerology mechanically, then a laser harp has to be the next step. I can help when it comes to the laser side of things. Also how to trigger a note when you put your hand/finger in the beam. A joint project maybe? :o)

Nice build. I really like this idea. How are the electric motors are operating the hammers? I would have gone down the solenoid route. Also, driving via serial from PC - how does this interface with the computer, and (presumably) sequencing software?
@fronkenpoop - The computer interface is parallel - the printer port - so it is just simple on/off. There are several (or there used to be several) DIY relay boards for PC use on the electronic kit suppliers homepages. I got the driver from one of these pages and it is basically a simple step sequencer.
The reasons why I used motors are that 1) I didn't have to worry about the hammer mechanism as the motor is actuator AND fulcrum, 2) I had a bag of free motors.
There are 13 monostable flip-flops made with schmit triggers (74HC14) that controls the motors through 13 power transistors. This makes sure that no matter how long a note is held the motors will only be on for 200 ms.
There are two ways the schmitt triggers can be triggered: 13 wires from a one octave keyboard or a binary signal from a parallel port.
So in other words: There is no micro - only logic gates.
I have thought about making a MIDI interface though.
The problem with this the small one is the limited range - just one octave. The other one has two octaves. I have thought about playing "Love theme from Flashdance" on it.
I have actually now - by total coincidence - stumbled across a melody that can be played on the little glockenspiel. It is called "This is my life" and I will do it in the near future.
1) It plays more than four notes. There are also some in the beginning.
2) I only consider this a test run. I intend to use it for more music in the future.
3) I build this electric glockenspiel as practice before building a bigger one with two octaves and voltage controll. But the process was more or less the same so there was no point in making a video about that.
I don't know. I haven't tried. But I assume that it is quite like biting a handfull of nails, chewing on a wooden spoon, and licking the poles of a 9 volt battery :-)
JMJ! Very nice. I love it.

@fuzzybobbles - I am actually doing some experiments on the next step. But the next step for me is a theremin.

Please play us a tune on this thing (or the other one that you're building)!
Very nice work btw.

Thats a lot of work just to play 4 notes.

Yes, but:

I was just giving you a hard time. This is a lot more than I can do with circuitry. Keep up the good work!

Hej ..
Du ved godt at JMJ spiller i Århus fredag d. 6.05.09 ?
Exclusiv lille koncert med plads til 3600.
Måske er der stadig billetter, jeg kan sende dig et link med rabat så de koster 300 stk. ?
Vh

Congratulations for this machine (that I believe that it(he,she) is midi) or bass manages with the feet, type organ? Very ingenious. Regards Manuel.
manuelyamaha55 2 years ago
It doesn't have MIDI - but it would be easy to add. It can be controlled by a set of pedals if I add a plug that fits the pedalboard cable.
At the moment it is controlled by a parallel port.

I congratulate you, it is practical to do so but how long it takes to make these electronic campaigns? I hope you are well ...........

It took about 3 days to make the glockenspiel. But I was going to do it anyway and it didn't take longer to do it with the camera documenting it.
