I built a compact, text-based driver for the Sharp LS013B4DN04 that uses 8×8 fonts to show a 12×12 character display. It uses only 174 bytes, refreshes changed rows, supports inverted characters, swappable fonts and scrolling. Read the full post to see the demo and code.

I published the simple version of my data logger that adds external FRAM for more records and higher precision. I explain why FRAM lowers power use and speeds writes, how the software lets you swap storage (flash or SD), and the small hardware change if you already built the minimal version—read on for steps.

I've released Lucky World, a compact jump'n'run for the MeggyJr RGB featuring an intro, 16+ levels, secrets and an end scene. I squeezed it into ATmega328P limits and shared the sources under GPLv2. If you're curious, please read on for downloads, requirements, and play instructions.

I documented the source code for my color-changing Xmas decoration and pushed it to GitHub, adding comments and safety notes about parts you shouldn't copy. If you're curious about the implementation or want to build your own, please view the repository and the full project description for details.

I tested a prototype of my Cat Protector and then built the finished device. I’ve added a new page that walks through the whole process—design tweaks, parts, assembly, and final testing—in clear, practical steps. If you’re interested in building or learning from the project, please read the full walkthrough.
