“We decided a few weeks ago to use the Android as a remote controller instead of building a remote control from scratch. We had started developing our android controller with Google Labs App Inventor but one of the guys over at LMR did the same thing and put it on Android Market for $2. So we decided to use Chris the Carpenter’s RocketBot Controller.”

“Last year, before the holidays, my friend and I had an idea to make a device, which will notify police via GSM if someone breaks into the house….This description has the resulting device which is tested and works well, and it is also relatively inexpensive, as compared with similar products on the market.”

“This project measures the background radiation outside the house, and transmits it to a display station inside the house. The outside sensing unit is solar powered (but it doesn’t have to be), and should have a range of at least 50m.”

“The aim of this project was to get a decent pair of wireless headphones, without breaking the piggy bank. I’m talking decent, as in comfortable, good bass, good treble, good listening distance, battery lasts all day, etc.”

“In this article, i will use the PIC 16F1937, a powerful microcontroller with a 16-channel capacitance module. I will only use the 4 of them, but the idea to expand it to all 16 channels is the same.”

“Speak into the transmitter and others hear you on any FM radio. The transmitter can be built in an afternoon with simple, affordable and widely available parts. Construction is fun and much can be learned although performance is modest; for example, your voice gets difficult to hear at distances greater than 25 feet.”

“Developing a total D.I.Y. space program – (Building / Lauching / Operating). Must Have: Commercial electronic components ONLY spacecraft: Aerospace grade components are very expensive and even not possible to buy as an individual. Cheap launching cost. Private & cultural missions: needs worldwide discussions to justify future private space program”

“The IR object detection module is quiet easy to make. This circuit below is a low cost / low range object detection module that you can easily make at home using IR sensors. We will use a photodiode and IR LED to make a simple circuit. IR led looks like a regular LED that you usually see in Television Remote controls.”

“Mister Gloves is a wireless USB gesture input system that enables a person to use a computer by performing intuitive hand and finger motions in the air. While wearing a glove controller on the right hand, the user can move the cursor by forming a pointing gesture and click by curling the index finger or thumb. Other right hand gestures enable scrolling and provide access to various keyboard shortcuts.”

“This amplifier will work great with the crystal radio project. It will enable you to pull in weaker and more distant stations. Local strong stations will have extremely loud volume.”
