@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.

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.

@dbini

My first instinct would be Makey Makey as well, but my second would be to use the guts of a wired mouse and make a button that completes the circuit for the left-click (potentially even remapping the mouse click on the computer to an actual keyboard key so you don't need an Isadora Control Panel with the mouse over a button to trigger whatever it is that you want to trigger).

Hello folks,
What do you think would be the simplest, cheapest, easiest and most reliable way of adding a physical button to an Isadora system for a kind of kiosk installation? A momentary signal from a push button would be perfect for things like resetting, or capturing a JPG of the stage.
I have a couple of wooden boxes that house MIDI controllers, each with custom buttons that poke switches or keys on the controllers, but these are a bit of a waste of space.
Something like a Makey Makey Go in a custom box might be nice, but it's difficult to get hold of the boards these days.
How easy is it to dismantle an old keyboard and build a single-key case, then have it USB'd into Isadora and use a keyboard watcher? (this would be in addition to the main keyboard)
I guess Arduino would be an option, but that requires a bit of programming. Could anybody recommend a good, cheap board for this?
