I built a small, extensible MicroPython Bitmap Tool to convert images into ready-to-use MicroPython code fragments. It has a simple UI: choose a format, load a bitmap and copy the code. If you work with embedded displays, please read the full post for downloads, source and build instructions.

I created the Pattern Generator to help you arrange circular shapes evenly within a frame. The app gives detailed control over placement, shape, and color, and lets you export SVG, PNG or JPEG and save projects. Read the full guide to learn how to make and reproduce patterns.

I built Micro Disk to generate tiny, read-only SD card images for resource-constrained embedded projects. It creates a simple ASCII-named file directory with block-aligned files and can target older non-HC cards. If you work with SD-based devices, please read the full post for downloads, usage, and format details.

I created Font to Byte to convert PNG bitmap fonts into byte arrays for microcontrollers. It runs on macOS 10.10+, supports bit inversion and reversal, multiple modes and output formats, and lets you copy or save generated source. Read the full post for instructions, templates, and a download link.
