I really am trying to pull my weight as far as researching and not just depending on others for answers but I also truly appreciate being able to reach out and discuss this with someone so knowledgeable.

I can't think you enough for the information you provided and for your patients with me. In the last question is for the EPDM rubber sheet would you recommend any particular thickness? Is the placement of the sensor intended to be in a certain quadrant so that other sensors will be added for your particular project? I've always assumed I would just need to center mine and I'm only trying for one drum trigger to begin with. Sorry for being a long-winded, I genuinely apologize but I want to try and get this as correct as I can because I know unexpected things will pop up anyway.įinally a couple of miscellaneous questions, can you tell me the diameter of the PVC cap that you got, and do you find it to be a comfortable size? Also looking at their data sheets there was a pretty big difference in reverse voltage capability between what I got for the 2017 example and for the type your recommending here. Also the type of diode you recommend in the example from the other day is still a Schottky type but I suspect I need to order those separately (the 1N5817) because again I assume there's a reason for the different component recommendations with this newer example. I'm guessing the parts that I got previously will not apply for the example you posted the other day - I have no 1Mohm resistors but I can get some, as I'm guessing the gap in what protection they would provide is considerable. Belatedly I noticed that thread was from 2017, and I think I would have a much easier time going along with the example you posted now. I pictured the parts listed such as the 470 ohm resistor and the 10K ohm resistor, as well as diodes that were a specific number you mentioned (1N4148). In that thread you described what sounds like a thorough and cautious way to build a circuit and keep it under control so that there's negligible risk of damage to the Teensy board. Originally, I saw your initial reply to me which linked to this thread:

If I may, I was hoping to ask you a few questions about the setup that you've described there. I hope it doesn't seem like I'm looking to have my hand held.I know I'll be making plenty of mistakes as I go so the learning is guaranteed, lol. To that end I have to say thank you so so much for providing the example that you have. My brain kind of got overloaded with all the different approaches and materials people were throwing in to make their own drum heads even if they were only making one versus a whole kit. I just need an idea of a direction to go in and I'm okay if it doesn't work out perfectly. Heya, Paul! This was exactly the kind of information I was hoping for. This is a prototype with the goal being drumsticks hitting whatever the drum head is made of, and sending voltage to my Teensy 4.0 to transform into MIDI velocity values.ĭoes anybody have advice on the materials to use? Thank you so much for reading and for any info anyone can provide!! I'd also like to ask if you guys think metal is required because I have seen a couple of examples where the sensor itself was attached to the center of a metal disc. I've also seen rubber recommended but I'm not sure exactly what I'm looking for when I go to the craft store. This is a follow up on a post I made under project guidance so I apologize for the double post but I can't seem to get a reply.įrom what I can tell, foam is advisable underneath whatever the piezo sensor is attached to in order to control extra vibrations from drum hits (ideally I want to be able to use drumsticks on this). I will attach a product link if that helps, just let me know. I am using a ceramic piezo sensor and the entire disc is about 1' diameter. Hi all, I'm trying to check around to see exactly what materials people have used to create their own DIY drum pad projects.
