Home-made GPS and compass

Posted December 21, 2019 by Chris

“This is a project I started about a week or so ago and have been working on when I find time after work. It’s a GPS and compass that temporarily uses an Arduino Nano micro-controller, Nokia 3310 screen, EM-406A SiRF III GPS receiver, and a simple (non-tilt compensated) magnetometer for compass heading.”

Using Internet Of Things To Turn On A Computer

Posted December 20, 2019 by Chris

“I have a computer in my apartment which I mostly use for playing video games, but sometimes I like to access it remotely over the internet to do server tasks for me. The problem though is that gaming desktops use a lot of electricity when they’re running. So running the computer 24/7 would be too wasteful. Instead, I want to be able to turn on my computer from anywhere on the internet; whenever I desire to use it remotely.”

Little Helper: Logic Analyzer And More!

Posted December 18, 2019 by Chris

“Working in my lab with electronics I came across different little challenges once in a while, and noticed that I am missing tools to handle them efficiently. Just a quick list, I am sure you could add various items to the list…Of course these aren’t any issues that you could not handle with the tools you have. But each of these take time….so, announcing the Little Helper!”

The Raspberry Pi as DVB-S digital TV Transmitter

Posted December 16, 2019 by Chris

“Some extra hardware and software changes the Raspberry Pi into a DVB-S digital TV transmitter. The code and diagrams are released under the GPL license. Credits: This project would not have been possible without the pioneering done by Jean-François Fourcadier, F4DAY. I also made use of simplifications made by F4AGC, I simply simplified things some more. “

LED Matrix Mask Built On AVR ATmega8

Posted May 24, 2018 by Chris

"AVR Mask1 is a led mask built around 74hc595 shift register and 8×8 led matrix.It has 4 8×8 led matrix, 2 for the mouth, and 2 for eyes. When the user get closer to the mask, the IR sensor placed on the back activate the mask."

Arduino CAN-BUS OBD Gas Gauge

Posted May 21, 2018 by Chris

"My inspiration for developing this gas gauge was after purchasing a new car (Scion Xa) and wondering what MPG I was getting. After much research on ODBII protocols, and looking into open source software that already existed I delved into my first Arduino project."

G-Scale Model Train Automation Control

Posted May 18, 2018 by Chris

"As we enter 2014, I thought I would post up a recap of what I’m working on. Primarily I’m developing a wireless method for controlling moving vehicles. In my particular case, this is Garden Scale (G) model train locomotives. However the principles and widgets I’m designing could be used to drive almost anything via real time wireless up to a distance of about 300 ft."

Pentax DSLR IR Interval Timer

Posted May 15, 2018 by Chris

"I’m planning a trip to the desert, and one of the things I wanted to make for myself were time lapse movies of sunrise or sunset, and the night sky. My DSLR does not have a wired remote capability and Hoya has decided not to include an interval timer on their low end DSLR…So, many months ago, I tore apart one of the Pentax IR remotes, to see what makes it tick."

Emanual Version2 – Ready for the Playa

Posted May 11, 2018 by Chris

"…I had a vision of a different kind of vehicle for that year. What I wanted to make was a self balancing extension ladder. You could ride it around the desert while standing on a rung, and then when the dust storms kick up, you hit a button and whuup!, the ladder extends and lifts you right above the low-flying dust clouds. Sounds fun? I thought so."

3D Music Visualization with Spinning Display

Posted May 8, 2018 by Chris

"As a device that is primarily for entertainment purposes, we want the final design to be simple to control, portable, easy to use and cool. Thus, we decided to generate 3D visual effects by spinning an LED screen around its middle vertical axis. The screen is 10×10 and is a mix of red and yellow LEDs."
