A stepper motor is a motor that moves in steps. Well, DUH! Isn’t that obvious? But it may not be. Because the notion of moving in steps is not as trivial as we may think. In fact, the ability to…
Slow, Mixed and Fast Decay Modes. Why Do We Need To Complicate Things?
If you are driving inductive loads, whereas it is a brushed or brushless DC motor, stepper motor, solenoid or a relay, you must have experienced a little bit of a problem in the form of an unwanted current flowing in…
Avayan’s CNC Electronics Overview
My electronics are ready to go. Everything except one board is of my design, and I am proud to report that as of today it is all working. The parallel port board is the only thing I bought. It is…
Yet another DC Motor Controller
I don’t know why, but a few weeks ago I felt like improving my AE-DC1 DC motor controller. At least the results were pleasing. The AE-DualDC3A module is considerably easier to use than its predecessor. It is just a little bit…
Cobotrox I in Action
Like I explained on my previous post, I was finally able to take my old electric wheel chair platform and remote control it by using a very simple decoder that takes RC PWM signals and generates DC Motor PWM signals.…
Wheel Chair Robotics – Adding Remote Control Functionality
A great deal of the robots out there are basically just giagantic remote control contraptions. Some people will argue there is little roboticism about that, but I think remotely operated mechanisms do qualify as robots. After all, imagine a machine…
