Well well well, things have changed up a bit in this project. It turns out that manufacturing can be kinda tricky! However, software can be distributed in seconds across the internet.
So what is really needed to solve all of your automation problems is a piece of hardware you already have which can be used to trigger computer automation via easily- distributed software.
...and as it happens, the answer has been right under my fingertips (and yours too) all this time - it's the numeric keypad built into your keyboard (or a separate USB one if you like).
Oh yes, today I am launching Numpad Superpowers - a Windows application which allows you to to trigger drag-and-drop automation with your numeric keypad.
Even better, because it can be easily distributed, I am giving away the first 125 licenses for free! You can find out more and download it here: https://numpadsuperpowers.com/
I'd love to hear your thoughts on this - feel free to drop me an email at email@example.com if you have any comments or questions.
