MCM Electronics Daily Deal and Bulk Bargain

Digital Temperature Sensing

Posted July 29, 2017 by Chris

"This circuit is simply a digital thermometer. I use a Microchip PIC Microcontroller to communicate to a Dallas DS18B20 Digital Temperature Sensor, interpret the data, and display the temperature on a multi 7 segment LED display."

Raspberry Pi Serial Breakout Board

Posted July 26, 2017 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."

DIY Mini Tesla Coil

Posted July 23, 2017 by Chris

"How to make a mini Tesla coil ! In today’s video I’ll show you a great idea, a long awaited video about how to make a Tesla coil at the minimal expenses. It’s very easily to make a Tesla coil at home."

Raspberry Pi Defcon Sign

Posted July 20, 2017 by Chris

"DEFCON or Defense Condition is an alert system utilized by the United States Military and indicates a level of alert ranging from DEFCON 5 (least severe) to DEFCON 1 (most severe). The goal of this project is to create a Defcon sign in the same manner that is driven by simple commands sent to a particular twitter handle using a Raspberry Pi as the controller."

Starting A Build of an Arduino Laser Tag System

Posted July 17, 2017 by Chris

"For the past few months, my friends and I have been planning to make our own laser tag system that we can play at home. The goal is to make a laser tag system that we can modify and program different game modes. Why are we doing his? We just want to play some laser tag, and learn a couple of things along the way."

Bark Opening Door System

Posted July 14, 2017 by Chris

"Sleep deprivation has been driving me mad recently. And it’s all down to a new member of the family, our new dog. She barks at night when she’s left out. She barks early in the morning when she’s left in. So once I recognized the patterns of her barking, I realized that all I needed was something that would let her out when she needed to go for a pee, usually around 6:30 in the morning."

FPGA Driven Nixie Tube Speedometer

Posted July 11, 2017 by Chris

".Anyway, Luke Miller over at FPGA Expert recently bought a vintage pickup truck and wanted to trick it out a bit with some custom electronics. He decided to use GPS to measure speed rather than hooking the speedometer directly up to the truck’s sensors, this way the project could be replicated on any make/ model of vehicle. Luke is using a Pmod GPS receiver which he is then running through his Basys2 Spartan-3E FPGA board to make this thing work.quot;

Temperature And Humidity Sensing

Posted July 8, 2017 by Chris

"The temperature and relative humidity of indoor air is an important parameter that can influence indoor microbial survival, abundance, and community structure. Temperature and relative humidity can also be used to infer other information about indoor environments, such as whether or not it is being heated or cooled."

Humanoid Robot Giger

Posted July 5, 2017 by Chris

"This bot was designed in Autodesk Inventor, and machined from 5052 alloy aircraft aluminum using a Sherline 2000 CNC and some work from Rapid Sheet Metal. He stands 62cm tall, weighs about 5kg and uses a total of 10x EX-106+, 6x RX-64s, and 8x RX-28s."

Sunrise Simulator

Posted July 2, 2017 by Chris

"Waking up in the morning is a daily and early task. Throughout my life I have used different ways of waking up: the usual alarm clock connected to a high power siren and flashing lights, a high power buzzer fed by AA batteries hooked to a portable alarm clock, and of course the most used is the mobile phone alarm."
