New PCB’s from BKRtech

As you can see from the picrures they are great, and the projects they’ll server are great also.

Some of these projects will be submited here on Youritronics for more free PCB’s , i only hope more of you join the program because, there are more free pcb’s to be given.

3in1 Stepper Motor Controller

This article was submited by morgoth and is part of the PCB giveaway program, so for submitting he’s work morgoth will receive a free PCB. Also in the future we’ll see more of he’s projects.

Of-course there are other projects based on this idea around the web, but what makes this one special, it’s he’s features. There are 3 stepper motors controlled by a single ATmega8 that runs at 8 MHz, and a motor driver for each motor. The motors and their drivers were recovered from an old printer.

Although the motors are controlled by the same microcontroller each one can move independent. The board can receive commands to drive the motors trough serial interface from a computer. There is also a PC software that enables you to send commands from a nice graphical interface.

As you can see this is a very practical application, for example it can be easily developed into a CNC machine. I personally like morgoth’s coding skils and i think he has some more great projects to show.

And in the ending here is a movie with the motors in action.

Happy Birthday Youritronics

1 Year down many more to come. One year ago a friend inspired me to start this project, and it’s been great since then. Every month the number of visits is increasing and this is making me happy. I have some new ideas that i will present to you this “new year”, i hope you’ll like them.

I have to thank my readers for reading this blog and commenting and i’ll try not to let you down.

Also thanks to my fellow bloggers that helped me along the way:

Stay tuned, there are some great projects coming up.
