“At first a few months ago I saw this Veear EasyVR speech recognition module, and I bought one on ebay because it looked pretty cool. When I got it I thought it might be a cool idea to control my room with it, and the idea was born to make my bedroom controlled by voice!”

“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.”

"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."

"…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."

"This is a motor driver board that can drive 2 DC motors in Forward or Reverse with full speed control. It can handle at least 25 amps per channel continuously at 24vdc. I designed it using a basic H-bridge with 4 switches, 1 switch going to positive (+) and 1 switch going to negative (-) for each motor terminal."
