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 streaming or sandbox-free environments. The project ships battle-tested, CPU-friendly implementations for common image/container formats and bit-twiddly primitives like Huffman and checksum routines. ... -

Selfie
An educational software system of a tiny self-compiling C compiler
...The Selfie Project provides an educational platform for teaching undergraduate and graduate students the design and implementation of programming languages and runtime systems. The focus is on the construction of compilers, libraries, operating systems, and even virtual machine monitors. The common theme is to identify and resolve self-reference in systems code which is seen as the key challenge when teaching systems engineering, hence the name. Selfie is implemented in a single (!) file and kept minimal for simplicity. There is also a simple in-memory linker, a RISC-U disassembler, a garbage collector, L1 instruction and data caches, a profiler, and a debugger with replay. -

Arduino Launch Control System (LCS)
A single rod model rocket launch control system using the Arduino Nano
This is a single rod model rocket launch control system. The system utilizes the Arduino Uno/Nano to report on local weather conditions (temperature, humidity, barometric pressure). The system also provides a 10-second countdown when the fire button is pressed. The system meets and exceeds the NAR Safety Code standard for model rocket launch systems as it incorporates a removable key to block the flow of power to the launch pad. It incorporates an additional two-button safety system to... -

Did the pets eat?
AM/PM Digital Reminder (Pets, Pills, etc.)
...One button is to change from AM or PM, and the other is to turn on one of the LEDs representing the current choice for 5 seconds. The unit then goes to sleep, and the LEDs are off. It is powered by an 18650 and I put it all in a medicine bottle. A description of it's construction, as simple as it is, is at an instructable here: https://www.instructables.com/id/Did-We-Feed-the-Pets/ Current draw: Awake: 5 mA Sleeping: 0.13 uA (!) -

NodeBrain
Rule Engine for State and Event Monitoring
NodeBrain is a rule engine for construction of state and event monitoring applications. It interacts with other monitoring components to perform simple element state monitoring or complex event correlation based on user specified rules. It is extended through the development of node modules (plug-ins) using NodeBrain's C API, and servants (programs written in any language) that interact with the rule engine via stdin, stdout, and stderr. -

AppM Build Automation
Automated software application for constructing and building projects.
AppM Build Automaiton is an open source and automated software application that is used to construct and build projects on different operating systems and using different development environments. General principles of implementation: -Each project must have a Build Project File, containing the necessary information on the construction of the project. For example, a unique name of the project, dependence on other projects and libraries, methods of construction, etc. Thus, the entire repository should be marked by the project description files to provide unambiguous information on the projects and their dependencies. - AppM Build Automaiton must be able to perform different actions (project construction, external applications launch, file copying, etc.) which are needed to build a -product... -

NanoCap
Carbon Fullerene and Capped Nanotube Generator
NanoCap is a generic application for the construction of low energy fullerene and capped nanotube structures. It provides an ideal tool to accompany the study of finite carbon molecules using computer simulation. The implementation involves a standalone application which includes a GUI and allows for dynamic visual inspection through 3D rendering. In addition, the NanoCap core libraries can be used in custom Python scripts that enabled the user to produce structures in bulk or to include the structure generation routines into pre-existing code. -
