Hi,

I bought one of these usb key and use it to control the "Pause Engine" in Isadora. It's not very robust, but it works well.

@juriaan - would it be hot-pluggable? 

@dbini

Well you can still attach a usb cable to it, up to you

@juriaan - and therein lies a problem - battery power=compromise of reliability. a Korg NanoKontrol in a box with a USB cable is going to be more reliable than anything that needs recharging, but the form factor is very different.

@dbini

With a lithium battery

@agentsimon2 - if it's wireless, how is the ESP8226 powered? 

@dbini I would definately use an ESP8226 with a small button. You can send the information wirelessly using OSC to Isadora. No wires, much neater. MArdiono has an example button with no bounce script you could use to create an OSC signal and once in Isadora you can read it and trigger anything you want. 

@otto22 Hi. This might help https://forum.arduino.cc/t/2-s...

Hi all,

Does anyone have tips or sample contracts for situations where you’re re hired by a musician (as is often the case for me, but could be performance group or similar) to perform live visuals during their shows?

It’s mainly to clearly set things and split ahead of time and avoid issues later.

– not a key because it go through OS and you are never sure of the destination.

– midi button its the easiest solution, but not easy to find a tiny one. 

– arduino + tiny button the best way for me. Not so difficult to code and many examples available.
