"Hi, I bought two small servo motors last month. I was thinking what I can do with this two servo, since it is only two in number. Then I asked this to my friend Achu Wilson and he suggested me to try a four legged two servo walker and he shown a youtube video in which some one demonstrating it. Then I also got interested to make some thing similar to that."

"This project is a small LED matrix sign/display/badge intended as an SMD trainer…I designed this version from scratch to make it a bit bigger to allow the use of larger LED’s (easier to hand solder), and use a “better” microcontroller to allow more creative programming (in C)."

"The Witness Camera is a combination of a VGA CMOS camera, a passive-infrared movement sensor, a 1 GB SD-card (or bigger), and an AVR Mega32 microcontroller implementing a solid-state time-lapse recorder. It is a compact, complete, self-contained surveillance system designed with home users in mind."

"All parts were developed separately. This allowed adjustments in the assembly as well as smaller changes in case the design of one or other part become required. The focus was on low cost and use of materials easily accessible in the local market."

"Up until now I’ve been using a photogate sensor and the Camera Axe to take pictures of water and milk droplets. After some research I found many – people – online were using solenoid valves to create droplets and take pictures of them. The big advantage to this method is it’s easy to collide drops which is was very difficult and random using my old method."

"I wanted to go for a mad science robot look. I really liked pictures of robot face prototypes with electronics sort of bursting from the back. I envisioned control wires coming out from behind a mask and running all around the room to control various things, looking like hair, or veins, or roots, depending on which analogy you wish to use. The face was easy enough to procure; Hobby Lobby sells basic androgenous masks. I also wanted a few animatronic features, like a moving mouth. For this, I took a geared DC motor out of a Billy Bass singing fish."
