One general purpose utility I like to keep handy for tracking down MIDI problems is MIDI-OX. You’ll need to, of course, run the MIDI through your PC. It can monitor all MIDI messages and show you what’s going on. Since it works on the MIDI level, it can show problems with timing, voltage, malformed messages, etc., that a serial monitor can miss.

I bet you could do this project all analog (no MCU) with a 9 volt battery, a protoboard and a mixture of transistors, capacitors and resistors. Otherwise, here is the first listing from googling "neopixels guitar" https://www.hackster.io/Corey_Childress/guitar-leds-dd5433

It's this phone which I ordered new from Amazon. I verified the microphone side has those black/yellow wires which you can see wired into the audio shield in photo one. That braided cord goes to the handset.

Looks very neat! I'm working on the same for my wedding :)

Any chance you could please share more info on how you wired the 10Ah LiPo for power? Or do you know if using a usb power bank like this into usb would do the trick? I'm a hardware noob over here, my background is in software.

So if I run the 5v power supply through the VIN into the teensy 3.6 it's lp38691 voltage regulator will convert the voltage and not fry the board?

And if I run the 5V LEDs Data in through the Octoadapter there will be some kind of voltage regulation so it won't fry?

So I won't have to worry about voltage regulation of up to 6.0 volts going in because of the Octoadaptor and lp38691? and my main concern should be how the teensy will actually fit on the adapter as it doesn't have the form factor of previous teensys like the 3.2? So should I use some special kind of pin headers or something?

Also is the Ampage or Wattage something I should be concerned about?

I intend to power 1k LEDs through this power supply which has 5V 60A and 300w as far as I understand I may need 2 more of these power supplies to have the maximum brightness of the 1000 LEDs

you can also use a i2c multiplexer to get MORE than 2 mpu6050s going.

In fact, you can get at least 16 mpu6050s working on the same arduino using this multiplexer.

https://www.amazon.com/DAOKI-Expansion-TCA9548A-Multiplexer-Breakout/dp/B07YKFFWHZ/ref=sr_1_2_sspa?keywords=i2c+multiplexer&qid=1637206719&sr=8-2-spons&psc=1&smid=A30Y6WWS77DGEW&spLa=ZW5jcnlwdGVkUXVhbGlmaWVyPUFFVVo5RkpGSzU0NDYm...

I think you can even use a multiplex 8 more multiplexers to get up to 128 mpu6050s going at the same ~time.

Rinse repeat...not sure when youd reach diminishing returns however, if you use a teensy 4.0/1 that sucker will get you 600MHz, probably enough speed to loop thru 128 units (mpu6050s) thru i2c chains

I solder pins on my Teensy 3.6 and then plug in one of [these cables](https://www.amazon.com/gp/product/B06Y5M6JTV/ref=ppx_yo_dt_b_asin_title_o02_s00?ie=UTF8&psc=1) from amazon. If I need more USB ports, I add a small hub...

Sorry, I wasn't very clear in my previous qustion. I want to be able to connect the teensy to another device that has a UART debug header (router, smart tv, embedded linux system, etc.) and use the Teensy as a serial interface with my computer. Like this adapter. Will I need a RS232 chip in order to interface with a UART debug header? Or can I use the UARTs on the Teensy itself without additional hardware?

I ordered a Project box (ABS box) I don't have it all put together yet. I'm waiting on a few more switches to arrive. The box i ordered isn't exactly want i wanted but it was as close as i could get. If you have any ideas for enclosures let me know. Walmart carries a metal clipboard that is like a box also that i think would work good but idk.
