“I admit: I love how home computers from the 80ies were booting up in no time. I’ve been trying to optimise the boot up time for Raspberry Pis for some time but I don’t get very far. I’m also fascinated by baremetal implementations where hardware is used for a single purpose and also works on an instant. Micropython is a nice idea inbetween as it is a “high level language” and still runs without too much overhead on very small resources.
Another thing that I’m dreaming of is to be able to write software on the go using a minimal dedicated device. My prrevious attempts comprise:
The StickPi (super small Pi Zero with an epaper display and no keyboard for ssh access from a notebook, no battery)
The PocketPi (battery powered Pi Zero, 800×480 4in Hyperpixel screen incl a small keyboard)
Last week’s PsionPi (battery powered Pi 3a+, Psion 5 Series keyboard incl Arduino keyboard controller and a 7in 800×480 screen)
And a yet unpublished 5in screen slate design.
All these are Raspberry Pis in different formfactors. When the Adafruit PyPortal Titano was released, I was immediately in love as it comprises a lot of nice hardware and a 3.5in 320×480 screen that I also had evaluated for the PocketPi.”
