Mozc Devices
Circuit diagrams and firmware source code for Gboard DIY keyboards
mozc-devices is an open source collection of circuit diagrams, firmware, and technical documentation for a series of experimental and often humorous Gboard and Google Japanese Input hardware keyboards, many of which were originally released as April Fools’ projects by Google Japan. Each subproject in the repository corresponds to a unique input device prototype, including versions such as the Drum Set, Morse Code, Patapata, Magic Hand, Piropiro, Physical Flick, Puchi Puchi, Nazoru, Mageru, Yunomi, Bar, Caps, Double Sided, and Dial editions. These devices creatively reinterpret how users can interact with Japanese text input, blending humor, engineering, and physical computing. The repository serves as an archive of the schematics, firmware, and PCB designs for these inventive input mechanisms, with many projects including promotional videos and technical references. -

Wuffs
Wrangling Untrusted File Formats Safely
Wuffs is a memory-safe, zero-dependency library and domain-specific language for writing high-performance image codecs and related parsers. Instead of trusting ad-hoc C, Wuffs code is compiled to C with strong bounds, integer, and state checks inserted by construction, aiming to eliminate whole classes of security bugs without a heavy runtime. The design prioritizes predictable performance: decoders avoid dynamic allocation by default, return explicit “short read” signals, and run well in... -

cwdaemon
morse daemon for the serial or parallel port
...Its development has been fully moved to https://github.com/acerion/cwdaemon on 2024.08.03. ------ cwdaemon is a small daemon which uses the PC parallel or serial port and a simple transistor switch to output morse code to a transmitter from a text message sent to it via the udp internet protocol. The program uses the soundcard or PC speaker to generate a sidetone. Current version of cwdaemon is 0.12.0, it has been released in May 2023. Source code for cwdaemon is available on github: https://github.com/acerion/cwdaemon -

JSON Parser
JSON Parser written in C that outputs JSON into D-List list objects
JSON parser is a highly efficient JSON data decoder written in C, that parses JSON data into a form that is very easy to use from within C code. You only need to include the json-parser.h file in your source code. If your project does not already incorporate D-List, you will also need to include dlist.h The JSON parser package also includes a JSON validator that does not parse or create resources, but allows the caller to validate JSON data from unknown sources, prior to any parsing attempts. ... -

clzw
Implementation of LZW compression algorithm in C
Simple, fast implementation of LZW (Lempel–Ziv–Welch) data compression algorithm in C. - Console encoder/decoder tools - OS independent - Could be used in embedded projects - Works with raw code-stream LZW features: - Hardcoded dictionary size - Variable code size - Code search is performed by hash table and embedded in dictionary linked lists (encoder) - No dynamic memory allocation -

MORSELIZER - morse with Arduino
A non blocking morse training software for Arduino
An asynchronous Text to Morse Converter and Morse training software for Arduino Uno, based on interrupts and Timer1. And because it doesn't use that evil delay() function, this solution morselizes random letters or whatever it receives through its serial() interface, in a non blocking manner. https://github.com/vicival/morselizer -

jpegant
Embedded JPEG encoder
...It is intended to be executed on small microcontrollers or microprocessors. High speed and small memory usage is its main concern. It implements a subset of JPEG standard. Now the code contains JPEG decoder so if you decided to use nonstandard transform or entropy coding in encoder you still will be able to decode bitstream (provided that you keep the decoder in sync of course). Release 1.1 source code and Windows executables are on the download page. For the latest release code look into the repository in 'release-1-0' branch. ... -

PolySim
Polymer simulation utilites
...It shouldn't be a problem to implement any new specific one (discrete models) 2) off-lattice monte carlo and molecular dynamics (continuous models) Latter one is rebuild of earlier version of simpatico (http://gemini.cems.umn.edu/research/morse/code/simpatico/home.php) project. Input and output are based on PDB file format which is better to visualize with pymol. For specific non-pdb input/output of 2nd program there are convertation utils also available. Programs are expected to compile in gcc under cygwin or pure linux environment. Scripts to run many copies of program under pbs/torque cluster system are also available. -

Morse Master
Morse Coder / Encoder
You can code to morse or enode from morse in a simple way. It's written in ANSI C, the source code is redy to be built for unix based systems. There can be bugs in it, but it does the work. I recommend the source code for those who are learning C. -
