Interesting about that 4k7 resistor at ~ 6:30 - made my own input board using a PC817 and a 330 ohm resistor mostly following the spec suggestion. Works, but my scope only shows it going down to ~ 1 volt. Wonder how low it needs to be to work correctly with an Uno.

Nice video, you could put a few headers on the pcb so you can change the supply voltage. A few extra resistors are cheap in low volume products.

Simple and efficient, I only replace transistors and associated resitors with inverters ICs and use a pC817, a very cheap opto, because I've got tons of those ! Thx anyway.

Hey, Dude!
I have a question: Why did you use transistors instead of a Hex Schimit Trigger IC?
Thanks!

Hello, really nice. I have two questions:
1. Is it possible to purchase this?
2. How can contact you to explain why would I like to use this product from you?

[ArjanvanVught]

You can simplify the design with replacing all the transistors with their resistors with one 74HCT04.

I have to do my thing now: DEATH TO TYPE B! LONG LIVE TYPE A! 😆(you should build a 4 port MIDI thru box ...)

Can act like a trigger on a scope then do something. You understand midi very, very well.
