Hello I'm doing this biodata sonification project, but there's a problem as soon as I send the code to my arduino I get this message :
"avrdude: stk500_getsync() attempt 1 of 10: not in sync: resp=0xb3"
I understood that it was coming from RX, I looked on the internet and tried all the solutions available, unfortunately nothing worked. Does anyone have any ideas ?
Thanks a lot!

I tired uploading the code after building the kit with an uno r3, there was a few problems with things not declared in the scope and things does not name a type. I'm not so sure how to fix these problems, has anyone else tried to run this recently?

Hello,

I have built the project and uploaded the code successfully but I am having an issue with getting a sound output. I don't own a modular synth but I bought a Midi to USB cable to use with garageband. When I plug the cable into the board and my computer, the computer detects it as a Midi input but when I switch the board on and try to get it to output something, it doesn't work. Any suggestions on how I can get it to work?

I would like to have a gerber file of the arduino breadboard-shield to upload to some pcb manufacturers to get a quote, e.g. pcbway which has a an online gerber view. Btw. I tried to place an order via your store for the feather-pcb, but it wouldn't accept my adress which is strange, I live in Germany. So if I can't order the feather-pcb I would appreciate a gerber file of that as well (would be useful to have anyaways, right?). Btw., I would really find it unfair if someone re-used the designs for commercial purposes, but I guess MIT would allow it.

I checked how to convert this (I am totally new to pcb design) and can open the sch and brd files with kicad and do an auto-matching of the layers, but the milling layer is not matched and I don't know how much of a problem that is and I also don't know if the auto-matching introduced any mistakes.

I would tend to build this the arduino way, because it seems much easier to get started with arduino than with feather, but regarding this project, the feather way seems to be much easier and less effort, also it offers more features out of the box, like wifi and bluetooth, whereas the arduino way is midi via a socket. Do you have any plans to add a bluetooth or wifi to that? I guess it wouldn't make that much sense because feather has it integrated already.

Hi,
Thank you so much for providing all these instructions!

I just tried uploading the code and it says this:

BiodataSonification_026:12:10: fatal error: EEPROMex.h: No such file or directory
#include <EEPROMex.h> //store and read variables to nonvolitle memory
^~~~~~~~~~~~
compilation terminated.
exit status 1
EEPROMex.h: No such file or directory

Do you know why this might be? Thank you!

Hey!

Thank you so much for all your instructions to make this kit!

I'm having some issues uploading the sketch, this error keeps coming up:

avrdude: stk500_recv(): programmer is not responding
avrdude: stk500_getsync() attempt 1 of 10: not in sync: resp=0x00
avrdude: stk500_recv(): programmer is not responding

Do you know why this might be?

Thanks!

Mati

Seems like there is a sort of problem with the menu. I can enter the menu via the push button, but LEDs stop flashing when turning the pot a couple of times (it's actually very random: sometimes I can scroll the menu once, some times twice, sometimes never). Even though LEDs don't flash, I can enter the submenu, but only for led number 1 (threshold mode) and led number 4 (brightness mode). I guess there is something strange either in the "checkButton" or "checkMenu" functions, but I cannot find the problem. Has anyone had and fixed this problem?

Hello! I have finished building this device and everything seems to be working properly. I am now confused about how to proceed. I know I have to download the serial midi converter, but my Mac wont allow me to. Can anybody help? thank you!

Spent about a week popping in here downloading the sch and brd files to try to get a sensible schematic of this project. Not having much luck opening the Eagle XML files on any of the apps we have available in this lab.

This seems like a pretty simple project. The step-by-step protoboard document seems like gilding the lily. Any chance you could put up a simple bitmap or vector image of a rudimentary schematic?

I don't find midi 5 din conector. Can you suggest me a solution to output the sound? With a buzzer is posible?

Hello,

Both the schematic and board EAGLE files for the Arduino shield show a CV out circuit, consisting of one capacitor (C3), two resistors (R10 and R11) and an audio jack (X1). It is not described in the pdf, but you can see it build on page 59 of the same document.

I want to build the Arduino shield, but the resistor values for R10 and R11 are very confusing. R10 is marked 3.9k / 10k, and R11 is marked 0.1uF / 1k. Especially for R11, 0.1uF is a capacitor value, not a resistor value.

So:

• Is this circuit meant to be a low-pass filter?
• Should the component labeled as R11 be a resistor or a capacitor?
• What are the correct values for these two components?

Hi all,

Just a heads up, the parts list at the top of the pdf asks for a 100 ohm resistor, whereas page 9, where the resistor is used as a pull-up requires a 100k ohm resistor.
I ordered the wrong ones myself! Hopefully the 120k ohm I used as a replacement will suffice!
Thank you for making this project available, very exciting!

Regards,

Sam
