quite a comprehensive video. I tried something similar, although my aim was to get a robot playing an unmodified glockenspiel, so I needed to hit the notes from above. My first attempt with homemade solenoids didn't work because it was difficult to make springs that would consistently lift the hammers when not striking. I finally settled on an arm and a single solenoid.
Outstandingly well done video. I found the project interesting, and the presentation very clear and well organized. Walking through the steps on the white board worked wonderfully.
You guys are a good example of how our new generation should be, smart and simple. Sadly, Idol show's are wasting our kids into dreams of fame that happens for one in a million. Yet I salute you all and your smart video's.
Great project! In trying it I have some questions. 1. What are you using to power the solenoids? (volts and amps) 2. Are your slugs completely hollow or 1/2? 3. What MOSFET are you using? Also, I can't seem to get the solenoids to work with magnets on them. I am using solid metal nails I cut up for slugs. I am putting magnets on top, but when I connect power nothing happens.
Please note that with typical LEDs reverse voltage has a absolute maximum rating at 5 volts. So, it would be a good idea for reliable circuits to add a standard silicon diode in series with the LED.

Excellent project. I'm just getting into solenoids to control/hit stuff! This was great but surely that's not a Xylophone (from the Greek words ξύλον - xylon, "wood" + φωνή - phone, "voice", meaning "wooden sound") It's a Glokenspiel [German Glocken (bells) + spielen (to play)] Quotes from wikipedia.
The next time you want to determent the nodes on the bar lay the bar onto two supports. Get some iron from some sand with a permanent magnet. Sprinkle some lightly over the approximate locations of the nodes. Much like iron fillings over a magnet. Lightly hit the middle of the bar a few times with a wood object. After a few tapes the iron will delineate the real nodes; no math required. I have seen this work on a video only he was using wood.
HAHAHA! I didn't learn shit! I didn't understand but just a small portion of that. But it was great, anyhow. Had to subscribe to y'all's channel. Perhaps I'll be learn something!
You wasted alot of time explaining about the physics of different length metal that produces different frequency to build the xylophone. And that is a physics topic not so related to main (Robotic) project.. You should have simply brought a simple ready made xylophone and focused on your main topic the solenoids and PIC control. However; I congratulate you because you and your team are very talented in a way you can make idea so clear and easy to understand..Great video indeed...please keep posting.

We did something similar for an EE design project! Except that we took already-made solenoids.
Through an arduino, we can play songs on the xylophone!
Great project, great video. Answered all the potential questions.
This tutorial/lesson was presented very well, I really enjoyed watching it
reddit love! awesome video...you guys did an awesome job explaining the stuff. definitely hoping santa gets me a nerdkit for christmas

Was that just a regular old milling machine you used when you made the plastic housing for the solenoid?
@RE90 oh and i'm sure the red-blue-orange marker placement below the reddit alien was a treat to armenian fans like myself, right? :)
Great tutorial :)
THX so much!!! a really good vid!!
Why did you use Nylon for the solenoid cores?
Use a shift register with a latch and get polyphony.
Actually, since the instrument derives the sound from simple metal bars, it is termed a glockenspiel, not a xylophone.
1) rename it to 'orchestra bells' or 'glockenspiel'.
2) make it play MIDI files
3) move the hammers from striking the bar directly in the center
Wonder how it feels to understand all this...

Better response
you missed how to use the lathe
Thanks you nerds ;-)
@infernalruss - I wish you would learn to spell syllable ;)

It's a glockenspiel actually.

Those magnets are going to chip. Also you might want to learn to talk less nerdy (breathing!) ;-)
Why didn't you just buy a glockenspiel..
shat up
well, they are cool, but maybe not the coolest thing ever...
i wish he would stop bouncing his hands with every cyllablle
dude keep your arms from moving too much.
It's damn distracting.
