MCM Electronics Daily Deal and Bulk Bargain

DIY Remote Project

Posted June 23, 2017 by Chris

"Having good support for your arm/hand when operating these large sticks makes it a lot more comfortable, ergonomic and gives an accurate control. The major drawback is that it isn’t possible to carry or hold it without some sort of harnesses or extra support."

Raspberry Pi Gameboy Pocket

Posted June 20, 2017 by Chris

"The Pi-Pocket is a mini portable games console capable of playing Gameboy, NES, Sega Master System, Game Gear games along with other popular Linux ported titles such as Doom and Duke Nukem using the popular Raspberry Pi emulator front-end known as RetroPie."

Shuttle XPC PCI Expres And Wifi

Posted June 17, 2017 by Chris

"The Shuttle XPC has one major limitation when it comes to accepting two PCI-Express devices when one of those is your typical double-slot graphics card. Although you can find single slot cards these have a tendancy to either be economoy cards or ones that require additional cooling with water. "

Bitcoin Mining Farm

Posted June 14, 2017 by Chris

"An important factor with the decisions on hardware has been to get the minimum possible host hardware to support the graphics cards. Since mining on a CPU is impractical we have chosen the cheapest available motherboard with 5 PCI-Express slots (of any type x1 – x16) and configured with the least expensive CPU possible."

Seismic Sensor

Posted June 11, 2017 by Chris

"My original “Deer Repellent/ Seismic Sensor” recommended using a speaker with a weight glued to the cone as a vibration sensor (see bottom of page) but it recently occurred to me that the speaker could supply the mass itself. By gluing a standoff to the center of the cone, an inexpensive 2″, 8 ohm speaker becomes a vibration sensor with a natural resonance below 100Hz which is quite good."

Killtron 7000

Posted June 8, 2017 by Chris

"Killtron 7000 is a biologically inspired crab walking robot designed by me and my team at the University of Victoria back in 2011. The success of the robot was determined by how well it can autonomously navigate between several walls and how much weight it can carry. Many thanks to Aaron Gehman, Andy Berry, Tina Hung, Joshua Yin, Eva Sun and Yuto Hori for making this possible."

A Reverse Engineering Surprise

Posted June 5, 2017 by Chris

"A computer’s arithmetic-logic unit (ALU) is the heart of the processor, performing arithmetic and logic operations on data. If you’ve studied digital logic, you’ve probably learned how to combine simple binary adder circuits to build an ALU. However, the 8008’s ALU uses clever logic circuits that can perform multiple operations efficiently."

LED Logger v3

Posted June 2, 2017 by Chris

"The third version of the Led logger has run without any major issues. Based on uptime logging there has never been any freeze or malfunction. As for the LEDs, I have identified a few types of strips based on the behaviour they manifested throughout the experiment. Careful about the axis scale of the graphs."

The Stubby Robot

Posted May 30, 2017 by Chris

"Stubby is an evolving hexapod robot which I am making, with contributions from my 6 year old daughter and a co-worker. I have long wanted to make a walking robot, thanks to shows like Stargate SG-1. While Stubby is not the same, it has been a very entertaining and educational project to work on."

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. "
