Micro-step driver

 

Micro-step driver
Here is a Micro-step driver for bipolar step motor.It allows to connect a bipolar step motor to a personal computer through the parallel port. The circuit is, for safety reasons, optically isolated from the PC and it allows to manage motors up to 3A for phase. Moreover the digital interface allows to connect up to six motors to a single PC parallel port.[more]

PWM Motor Driver with H-Bridge

 

PWM Motor Driver with H-Bridge
This pulse wide modulated driver is designed for DC Motors with a maximal power consumption of 200 watts. It works with a so called H -Bridge. It has three input pins, two for the direction and one for the pwm-signal. The inputs are designed for logic level signals ecpecially for microcontroller outputs.[more]

A Versatile Miniature High-Rate ESC with BEC and Brake

 

A Versatile Miniature High-Rate ESC with BEC and Brake
This ESC is an analog one, using off-the-shelf components. There are no microprocessors and no surface-mount parts. It’s not as small or as light as many commercially available ESCs, but it’s smaller than many other do-it-yourself designs. It’s also versatile, in that it can be built for many applications, ranging from small Speed 400 sport planes to “hot liner” sailplanes. [more]

Server tester

 

Servo Tester
This server tester can control two servos independently. It can analyse the servo signal quality from your receiver. It measures voltage and current under servo load. It can be used as a tachometer, and with a later software upgrade it can also be remote controlled from a PC.It uses a rotary encoder for fast and intuitive navigation of the menus, which make it even more simple to use than the old 4-button tester.[more]
