ulisp is great - I have it running on a little neopixel matrix I use to flag when I'm on video: https://github.com/dannyob/signpost
I'm ashamed of how much power that sucks down compared to this badge though!

#22First thing I looked for was dedicated parentheses keys, was not disappointed.
Probably should have put them on the center of the keyboard, though :)

#2440 hours with a coin battery is impressive, but I think it is a bad decision in terms of environmental friendliness.
"The Lisp Badge LE draws only 6mA from its CR2032 button cell, and so should have a life of about 40 hours"
I suppose that's 6mA when the CPU (MCU here) is active. In idle mode that ought to be much lower (the low power monochrome display, not eInk, draws only 30µA as stated separately). Does uLisp support idle mode? Uh, apparently not automatically, but requires the user to call a SLEEP function ...

#25I’d love if old Blackberry shells became standard casing for such projects. Perfect keyboard, good display size.
Blackberry-compatible motherboard with appropriate keys and nothing more may be done relatively easy, but where to get drivers for the display and the sensor joystick?

#26I love this guy. I ran across him trying to self teach about embedded electronics and his site is one of the best I’ve found both for interesting projects and good instructional examples.
I love his projects too. He's also the creator of uLisp. (If it weren't clear from the article.)

#27Dammit I haven't finished populating the last lisp badge.

Display and joystick goes on the PCB anyway. Just use what works. Bigger problem is BlackBerry, or anyone to be in their position, won't like that being done at scale.

Should have a spare set.
