The StarFishDAQ (or SFDQ for short) is a platform for developing MCU based hardware without having to start from scratch. It consists of hardware, firmware and software components. The SFDQ allows those projects that would otherwise use an off-the-shelf DAQ, PLC or MCU SBC to start with a stack of hardware, firmware and software. This allows more control, customization, and future applicability without sinking a ton of effort. The SFDQ can be used simply and quickly, as-is in...

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...

Basic Octave implementation of the matlab raspi extension, allowing communication to a Raspberry Pi board to control its hardware.

...It demonstrates proportional, integral, and derivative controllers and their features as well as anti-windup and control loop update rate. It uses a DC motor controlled by an h-bridge and an optical quadrature encoder for feedback. It uses timers, counters, and interrupts to generate PWM to control the speed of the motor, encoder pulse counting, and control loop updates.

Software application, firmware and U.I. for 4-motors 3-axis milling machine, open hardware, software and mechanics. See also project in details for schematics and images on http://www.contesti.eu/opensource/xyz-dc-motor-controller

The parallel port PWM and/or encoder kernel space Linux driver allows open/closed loop control of motors using the parallel port.

Brushless DC controller (ESC) Fully functional sensorless ESC. Uses BEMF detecton for rotor position sensing. Software trays to maintain maximum speed on currently available power(pwm duty). It works like ordinary DC motor. More load means, on same power, lower speed and higer current. Motor speed (current) PWM , direction etc. is adjustable via serial port commands. For example - press "k" button to add power, "j" button to reduce power and "t" button to reverse rotor direction etc. I have used neodymium magnets BLDC, CD drive BLDC and car generator as BLDC motor without any modification in software, hardware - it just works. ...
