This project demonstrates how to implement a PID based DC motor controller using Raspberry Pi. DC motor controller program is developed using Python. It consists of a GUI, RPM measuring, error detector, PID controller functions, and PWM generation function. The PID based closed-loop DC motor control system is one that determines a difference in the required speed and actual motor speed and creates a correction control signal to remove the error. To learn more about PID controller and DC Motor, g ...
This project is done with Open Source Computer Vision Library (OpenCV). OpenCV was designed for computational efficiency and with a strong focus on real-time applications. So, it's perfect for real-time face recognition using a camera. To create a complete project on Face Recognition, we must work on 3 very distinct phases:Face detection and data gathering, train the recognizer and face recognition. we will simply create a data-set, where we will store images for each id, a group of photos that ...
  Next Biggest Breakthrough for Raspberry Pi is here!       Today I successfully compiled OpenCL on raspberry pi 3, Opening the door for numerous GPU possibilities for Raspberry Pi, Love the performance in FFMPEG(1080p rendering) and now looking forward to Deep-Learning applications on this little beast.       VC4CL is a newer effort bringing OpenCL to the Broadcom VideoCore IV GPUs as found in the Raspberry Pi boards. VC4CL implements OpenCL 1.2 for the Vid ...
This was a great article to read - https://www.techrepublic.com/article/inside-the-raspberry-pi-the-story-of-the-35-computer-that-changed-the-world/   The highlight for Pi fan in me, was to hear it from the horse's mouth on why Raspberry Pi got that name and it is definitely an interesting story. ...
The good folks at the Raspberry Pi Foundation will launch a new magazine called Wireframe on November 8th, 2018 which is dedicated to showcasing Indie Video Games industry as well as including reviews, how the top games are made and how to make your own games.  This is quite timely since it is something I am personally interested in and currently working on.   For a limited time, you can get a free hard copy of the magazine shipped to you; cost $2 for shipping to Cali in the US.  ...

Arsenij Pichugin’s ZeroPhone is designed around the Raspberry Pi Zero, an Arduino microcontroller, and the ESP8266 module. (Image credit: Arsenij Pichugin via Crowd Supply)   I thought this was a fantastic use of a Raspberry Pi Zero, I had to mention it.   Arsenij Pichugin debuted his ZeroPhone in January of last year and was touted as a $50 open-source smartphone you could build yourself without all the hassles of using a carrier-based phone. A year later, the technology has ma ...
I'm building a SCPI programmable Lab switch with a Raspberry Pi and PiFace Digital. Communication is over TCP/IP. In this post: the LabVIEW drivers   What is this Lab Switch?  This is a lab instrument. A switch that can be controlled via commands, over the network. The switch hardware is a combination of two off-the-shelf components: a Raspberry Pi and a PiFace Digital. All inputs and outputs of the PiFace Digital are accessable via commands. You can read the inputs and set th ...

This very short blog post briefly discusses a simple project that allows for toy robot arms to be controlled using gestures. It had a serious purpose; it was intended to show latency.   However, it was also a bit of fun. There is immense pleasure in destroying Lego structures with a mere wave of the hand! There isn't a lot of documentation for this project here - this blog post is just to provide some ideas. To be honest it was quite straightforward, and components of it are documented in ...

The Plytop Shell

Posted by tinkerloon Apr 11, 2018
Hello, I've been a long time watcher of Ben's show. I thought this community might have interest in the project I've been working on for the last 2 years.     It's a laser cut 'laptop' shell that has room for a Raspberry Pi and power bank.The designs are open source and available on my site at https://www.tinkerloon.com/projects/plytop.   There's a couple of variants of the top, one that's just an empty top, so you can screw any LCD monstrosity you can find to it, and one espe ...
Unless you've been under a rock for the past 24 hours you will have noticed the new Raspberry Pi 3 Model B+ has arrived. We've had the privilege of having a couple of pre-production samples to test for the past month or so and this post summarises our first impressions backed by testing with the sample units. In a nutshell, we think it's a real winner! A faster core, better heat profile, wireless and wired network speeds up to 3 times faster and the real kicker, Power Over Ethernet! Read on to f ...
