@node Overview
@section Overview

I've been writing Common Lisp for at least a decade in earnest, though
the amount of time I spend on it ebbs and flows. I've written
production CL and Clojure, and written a fair amount of hobby racket,
scheme, and elisp. My imagination was captured early on by the book
Let Over Lambda, and of course all the AI books piqued my interest.

I found uLisp a few years ago, but I didn't really have a use for it
at first. I don't need a serial terminaly-only Lisp system given my
comfort in writing Arduino C++. I started work on an ARM SAMD-51
system using a Blackberry Featherwing from Solder Party, but never got
uLisp building with PlatformIO (where all my other tooling was).

When the PicoCalc came out and I saw it included a uLisp image, I
immediately bought one. This was quickly followed by T-Deck and
repurposing some existing Teensy 4.1s. I found a GameBoy cartridge
form-factor for the Teensy, and I have this idea of building a uLisp
Teensy cartridge with the additional PSRAM and an RTC, and building a
case for the PicoCalc that allows me offload expensive computations to
the Teensy. Alternatively, I could build a LoRa cartridge to combine
some of my radio interests.

@node Goals
@section Goals

My goal is to have a handheld Lisp platform that I can extend and
customize as needed to explore various maths and physics things, take
some notes on, and generally interact with the world. The T-Deck is
acceptable for now, but I'd much rather build on the PicoCalc.

I'm using a few platforms:

The @url(https://www.clockworkpi.com/picocalc, PicoCalc) is the
platform I'd like to have working where I want. There's still a bunch
of work to be done.
