Hi, I am trying to find the unit plans and the details for these projects to use them in my classroom and I can’t find any of them except the mission to mars. Is there a way to direct me to the documents from Knowledge in Action?

very cool! is it possibly with solenoids to also have different intensities of hitting? to have soft or loud tones and everything inbetween...
@MisterDevine2 ай бұрын
If you used transistors to control the solenoids, you can vary the amount of current they receive. With the relays, you can vary the amount of time they are closed (I used 8ms in this project, so a smaller time would be a less intense hit). The problem with this is that even subtle differences between solenoids (their internal friction, distance from the surface, etc.) means that some might not reach the keys at all while others do. In this project I had modes that did both (transistors and varied time), but also had a felt covered damping bar that could be pressed into the keys with varying pressure using servos. www.devinejohnny.com/projectgallery/midi-arduino-glockenspiel-with-tip120-transistors

For a 8 note xylophone, do you think we can use a ESP32?
@MisterDevine5 ай бұрын
Yes, but I don't know for sure how you might trigger the solenoids directly from a DAW. I think the software I mentioned in my blog post (in description) is depreciated. For my newer projects I use Hiduino, which lets you re-flash the firmware of an Arduino board so it is natively recognized as a MIDI device when you plug it into a computer.

Where do I find this curriculum? I have searched online, but just find a lot of people talking about how great it is and a few outlines of the curriculum, but no actual site with the whole curriculum for use or purchase. I would be very interested in purchasing / using the curriculum, but am having trouble locating it.

It seems that the AP Physics curriculum has been a work in progress for many years now. You can access the curricula from Sprocket (for free), which is the Lucas Ed portal for all the resources they've produced. Looking at this page (sprocket.educurious.org/home/curriculum), you can still see that the physics curriculum is "coming soon!" I made the video above because I was involved in some of the early piloting.

@MisterDevine Жыл бұрын
Thanks! You should still give it a go, though. I would recommend some changes if you give it a try. I think the software mentioned in this video is no longer supported, but there is something called Hiduino, which is really cool. With a second Arduino acting as an ISP device, you can re-flash the firmware for the USB chip on your Arduino so that is acts as a native MIDI device. That means once you plug in the instrument to your computer, boom, it just shows up in your DAW and is ready to play. I've done that with some more recent instruments, but don't have a full write up on my website yet: www.devinejohnny.com/projectdetails/m7jy1wa0aukmz9ory546gcr8xu0wa5

@MisterDevine Жыл бұрын
Yes, I imagine so. It just needs something sending MIDI signals. I really need to do another video and write up on my website, but all my instruments after the ones in this video use hiduino, which re-flashes the USB chip on the Arduino so that when you plug it into something it is recognized natively as a MIDI device. That means you could plug a keyboard straight into the instrument and play it. No need for a DAW, hairless MIDI, loopMIDI, or any of that jazz. It's pretty cool.

Nice work! There are N-channel MOSFETs that can be directly controlled by gpio lines from the Arduino. This could eliminate the 12v supply and relay clicks.

Thanks! I took that approach with a later, better build: www.devinejohnny.com/projectgallery/midi-arduino-glockenspiel-with-tip120-transistors I also flash hiduino firmware to the Arduino in that build, which eliminated all that extra in between software; just plug in the USB and I pops up as a midi instrument. I also did a build with ULN2004 transistor arrays, which really slimmed down the electronics. Didn’t document it, but here’s some more about those chips: en.m.wikipedia.org/wiki/ULN2003A

Of the two, the relay is much louder. I’ve put foam over the relay board before in other projects and that seemed to help. You could also increase the distance of the instrument from the relay, or put it in an enclosed box that doesn’t resonate. Working on a similar project?

I agree. There are pickups for guitar sound holes (or just placing the mic inside the sound hole may help). Quite a bit of dedication to the project, good job.

Everything I learned, I learned from the internet. I've always found the learning resources from SparkFun and Adafruit to be helpful: learn.adafruit.com/ learn.sparkfun.com/ Getting a starter kit with an Arduino and some sensors is a good idea too. There was also a commercial makerspace in my city that gave me the chance to try out tools like 3D printers and laser cutters before making the big investment to get my own, which really opened up a world of possibilities.
