...Each module can flip between 40 unique characters: letters, numbers, and a few symbols. Multiple modules fit perfectly alongside each other to build bigger displays. The primary design goal was to make something that's possible to fabricate at home in small or single quantities and can be customized and built by an intermediate hobbyist at a reasonable price. This meant using widely available materials and avoiding any tooling with a high upfront cost. Following that philosophy, the design uses store-bought vinyl stickers for the letters, is driven by an ubiquitous and cheap 28BYJ-48 stepper motor, and uses common PVC ID badge cards cut to shape for the flaps (though custom die-cut flaps are also available). ...

...BLDC motors have numerous advantages over regular DC motors but they have one big disadvantage, the complexity of control. Even though it has become relatively easy to design and manufacture PCBs and create our own hardware solutions for driving BLDC motors the proper low-cost solutions are yet to come. One of the reasons for this is the apparent complexity of writing the BLDC driving algorithms, Field oriented control (FOC) being an example of one of the most efficient ones. The solutions that can be found online are almost exclusively very specific for certain hardware configurations and the microcontroller architecture used. ...

...Completely stand-alone, does not need a PC to operate (unless for updating firmware). Easy to modify open-source code, write your own extensions and share them with others. Portable thanks to a battery. Modular design using mostly off-the-shelf components. Reads NES, Famicom and Family Basic cartridges including save. Supports Mapper 30/NESmaker and flashes INL NM30 boards. Reads SNES roms and reads/writes save games from and to the SNES cartridge. Supported cartridge types so far, LoRom, HiRom, ExHiRom, DSP, SuperFX, SuperFX2, SDD1, CX4, SPC7110, SA1 (last two chips need Adafruit Clock Generator). ...

The DarkLight Cover/Calibrator (DLC) is a DIY project to build a motorized telescope cover, flat panel, or a combination flip-flat system. Its modular design supports various setups: a 12V light panel without a servo for a wall-mounted calibration panel, a servo-only cover for sky flats, or both integrated into a flip-flat mechanism. The DLC also includes optional dew heating to reduce extra equipment and cabling. With available drivers, it works with ASCOM or INDI. We’re excited to announce that the DarkLight Cover Calibrator project has officially moved to GitHub! ...

SmartKnob is an open‑source hardware/software hybrid rotary input device featuring software-configurable end-stops and virtual detents, facilitated by a brushless gimbal motor and magnetic encoder—offering programmable haptic feedback and a novel, tactile user interface. 240x240 round LCD ("GC9A01"), protected by 39.5mm watch glass on rotor. BLDC gimbal motor, with a hollow shaft for mechanically & electrically connecting the LCD. PCB flexure and SMD resistors used as strain gauges for press...

Relacy is a framework for agent-oriented programming in C++. Agents are autonomous objects, they interact fully asynchronously with messages. Relacy provides means for defining user agents and messages, as well as runtime system.

Documentation, simulator, compiler, and Verilog implementation of a completely open-architecture graphics processing unit. This design is intended for academic and commercial purposes. The first step is to develop a detailed GPU simulator and compiler. The second step is to implement the GPU in synthesizable Verilog. The third step is to develop a feedback loop between the simulator and implementation, allowing power, performance, and reliability aspects of the hardware to feed back into ever more detailed and accurate simulations of a complete GPU. ...

Software and Arduino shield design for a Serial-to-HID device such that old serial gaming devices can be used as USB Hid devices, particularly the SpaceOrb360 and Spaceball 3d CAD devices.

FPGAsm is a low-level alternative to verilog and VHDL. A near-instant 'assembler for FPGAs', this simple yet powerful language facilitates bottom-up design, layout and wiring of modules, and generation of .xdl output. With about 10 keywords to learn, you can start making circuits in minutes. Now you can focus on learning the ins and outs of the FPGA instead of complex tools and languages. Fast turnaround time and bottom-up approach invite exploration, experimentation, live circuit testing and physical test harness creation, radically changing the workflow. ...

The OCCN project enhances SystemC2.0+ modeling by developing C++ classes for modeling user-defined or system-specific, point-to-point or multiaccess inter-module communication channels (or future network-on-chip) at various abstraction levels.

MDF is microkernel operating system. Module architecture minimalistic design.

This project is aimed to develop an Hardware Monitor & Protection System for PCs using PICmicros. This project is divided into two branches: the first one involves microcontroller's firmware, the second one software used to manage the PIC via COM po

Help port the tulip driver from free/net/openbsd to Darwin OS. So far the driver is written to the ADMtek 985 clone chipset and the PNIC 82c169 chipset. Due to IOKit's object-oriented design, the code can be easily subclassed to support new chipsets.
