Here’s the development machine. I love hardware that folds down almost as much as I love free hardware that I picked up because someone else didn’t need it, and this is a blend of the two.
Everything I have in this photo fits into the official touch screen box, along with a chunky battery and a spare USB lead for power. It’s a Pi 3 with blinkt hat, touch screen, Rii-diculously small keyboard on which yes, I genuinely type, and two Fold Holds (by Jonathan Woolf) to hold it all up and protect the screen when it’s packed. You might say the touch screen is overkill – I don’t have a GUI on the machine.
I’m going to design a hat to go on top, which will be able to fly out the unused pins currently covered by the blinkt, giving me breadboarded GPIO access. Nothing could possibly go wrong with that plan.
