MCM Electronics Daily Deal and Bulk Bargain

The Cherry Express

Posted May 27, 2017 by Chris

"Finally got the linebot working reliably. I’ve uploaded 3 images and a movie. I also included the modified Arduino script provided for the “method 1” servos and “V2 Adafruit_Motorshield” I’m using. My sensor board image shows the original 5 sensors described in your “Arduino Robotics” book, but you’ll notice now only the three middle sensors have signal wires, to match the 3-sensor script you provided. "

An Intro To Digispark

Posted May 24, 2017 by Chris

"In today’s blog post we’ll analyze one of the smallest and most practical boards out there. The Digispark board. It’s size, including the USB port, is 25mm x 18mm (so tiny)!! This little board is powered by an ATTINY85 chip and clocked to 16.5Mhz. For conveniece, it has a built in USB port and can be plugged into a your computer without cables or adapters."

The Lawnbot4000

Posted May 21, 2017 by Chris

"The Lawnbot400 is a remotely controlled lawnmower that I built several years ago to mow my lawn. It is basically a push lawnmower attached to a large remotely controlled frame."

Robotic Arm Tracks Hand Movement

Posted May 18, 2017 by Chris

"This past week, I made a robotic arm that tracks your hand in free space using a Leap Motion, Arduino, and node.js. It tracks my hand very well. It is able to pick up stuff and set it down with relatively good precision, although there is definitely some room for improvement."

A DIY Robotic ARM

Posted May 15, 2017 by Chris

"The CHORG project consists in both a hardware and software platform both of them developed by myself. The main purpose of this project is to create a robot arm capable of adapting a task to randomness of the real environment."

Building A Traffic Light

Posted May 12, 2017 by Chris

"The traffic-light project is something we did at work (Isotope11) to monitor our software projects. We are a software development firm and we handle some large projects that have extensive test code written to make sure newly added features or changes to existing features can easily be tested by running the test code against the changes."

Raspberrypotter

Posted May 6, 2017 by Chris

"Raspberry Potter is an open source project that lets you control things around your room or your house with a magic wand. Imagine if you had a magic wand to control everyday things. Once you make a Raspberry Potter, you’ll be able to do just that – by drawing simple gestures in the air."

DIY Drink Mixing Robot

Posted May 3, 2017 by Chris

"I built a robot that mixes drinks named Bar Mixvah. It utilizes an Arduino microcontroller switching a series of pumps via transistors on the physical layer, and the MEAN stack (MongoDB, Express.js, Angular.js, Node.js) and jQuery for the frontend and backend."

Circular Saw Cad Project

Posted April 30, 2017 by Chris

"There are instances were images are not enough to convey and visualize a final product. SolidWorks has a great animations tool that lets you animate the things you create. The video below shows the circular saw being taken apart."

3d Printed Delta

Posted April 27, 2017 by Chris

"Now having figured out how to make 3D models of the parts I need, I’m printing my robots like a more civilized maker. I’ve also departed from relying on hobby parts for the joints due to my friend Mark’s ingenious idea to implement ball bearings into the design. This allows the robot to be free of heinous amounts of nuts and screws as well as any additional bought items."
