MCM Electronics Daily Deal and Bulk Bargain

Chip-8 Emulator

Posted February 5, 2016 by Chris

"I’m taking a microprocessor applications class this semester and the final project was to spend the last three weeks making whatever I wanted. I ended up making a Chip-8 emulator for the PIC32MX270F256B microcontroller. Here’s the final circuit."

Designing and Building the Macro Watch

Posted February 3, 2016 by Chris

"Three weeks before the Houston Maker Faire Chris came to me asking if we could whip up a low cost giveaway for the faire. I wanted to giveaway something more than a blinky LED badge since that is the typical electronic swag at Maker Faire. It had to be something that the person would wear and would want to show off to other Makers to spread the word about MacroFab. Blinking LEDs are always necessary though."

Motor Controlled via Eye Tracker

Posted February 1, 2016 by Chris

"This section explains the details of the hardware and software used to create the eye-tracker controlled robot arm. Hardware: USB LEGO Cam, Simulated Eye, and LEGO Mindstorms NXT Robot Hand"

Mini-PCIe microcontroller and make your board too

Posted January 21, 2016 by Chris

"I have just recently finished this board, and been able to test it briefly with Springboard and also with the VAB-820. The picture just below shows the shining blue LED, that is tied to D13 – the 13th digital pin, as most Arduinos do."

My Business Card v2 (PCB Card)

Posted January 11, 2016 by Chris

"At the end of this month, I’ll be leaving my current job. I therefore thought it’d be a nice occasion to build a new business card for my future interviews. You may remember the first version of my business card made more than one and a half years ago (time flies!). It was basically made of two PCBs soldered together."

OSC and MIDI Foot Controllers

Posted December 10, 2015 by Chris

"The goal of this project is to provide open hardware design of OSC (Open Sound Control) and MIDI foot controllers, primarily targeted for use with SooperLooper, distributed under the GNU General Public License."

Raspberry PI Serial Port and Breakout Board

Posted November 5, 2015 by Chris

"A simple single-sided board that connects a RS-232 serial port to the Raspberry PI and breaks out some of the PI’s pins for experimentation. The interface board was designed to be simple and used for initial experimentation. It can be built on a single-sided PCB using home-made PCB fabrication methods."

Receiving SMS Notifications From Your Washer & Dryer

Posted September 16, 2015 by Chris

"In this post, I’m going to cover a new project I recently finished – creating a device that monitors a washer or dryer and sends a text message when it detects that a load of laundry has finished. Beyond the novelty and simplicity of receiving a text message when the laundry is done, I built this device for two reasons."

Making a Web-Controlled Robotic Arm

Posted August 31, 2015 by Chris

"As part of Programmers’ Day celebration this year, Azoft web developers decided to surprise our fellow Azoft employees with a competition. To try something new and unusual, we created an internet-controlled robotic arm."

Apple Extended Keyboard II Mod

Posted August 16, 2015 by Chris

"The biggest stumbling block to the project was the computer’s interface. The Apple Extended Keyboard II is from the days of ADB, or Apple Desktop Bus. The internet revealed two possible solutions: An expensive and sometimes-hard-to-find adapter by Griffin, or a $16 microcontroller and some DIY elbow grease. Naturally, I chose the latter."
