Lisp Badge (2021)

This looks awesome but I feel like it would get old really fast writing any amount of code on that tiny keyboard. Somehow doesn't stop me from wanting one though.

Typing on the keyboard is surprisingly fun.

For larger programs you can interact with the Lisp Badge via a serial console. Here's a setup for using Emacs's built-in serial support. This makes programming the Lisp Badge very similar to working in SLIME, with an on-target REPL and the ability to evaluate code fragments onto the target:

I used that mode to port Emacs's Tetris to the Lisp Badge:

After (save-image) and unplugging from serial, I had a portable Lisp-hackable handheld gaming system. I made small tweaks to the game code -- like new cheat modes or modified sound effects -- with the built-in keyboard.

At least it has dedicated open and close paren keys like the CADR keyboard!
