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."

Web Garage Door Controller

Posted June 29, 2017 by Chris

"I was motivated to find a new solution to controlling my garage door because I didn’t want to carry an extra remote around, and they just don’t work very well. This article demontrates how to use a CC3200 to connect to an existing garage door opener. The CC3200 acts as a TCP server which can send information about the garage door state to any network capable device."

Rain Detector Sensor

Posted June 26, 2017 by Chris

"This rain detector will give you a heads-up the instant it starts to rain, hopefully giving you time to close windows and bring in possessions. The battery-powered circuit draws virtually no current when the sensor is dry and the current consumption is low when the buzzer is activated so a couple of AA cells will last a long time."

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."
