By this controller operator will be able to Control DC Shunt motor wirelessly via his/her phone and through encoder too. This will give flexibility in controlling. Operator can control it while sitting in home. as it is PID controlled so speed is going to be almost constant.for feedback of speed ... view more

Halloween is close and I wanted to make a related cool project. Of course, it will involve a pumpkin. But to make it last longer, I’ve made a 3D printed one. After I’ve made a simple design and divided in a few parts, 3D printed it and give it a pain job, I had a cool looking plastic pumpkin.... view more

Yes, I've made another radio controller. Why? well, I wanted to have a more commercial look. So, I've designed a 3D case, then I've used some high quality joysticks in order to have better analog read, It has an OLED screen so we could see the data we send and we could also digitally adjust the d... view more
