“This project is an extension of interfacing microcontroller with hyperterminal and GSM module. The previous project explained a way to interface a GSM module with 8051 microcontroller where the information response and result codes received by the controller were sent back to computer to display them at HyperTerminal. In this project, the same output is displayed on a 16×2 LCD interface.”

“An intervalometer is a device that sends out a signal at regular intervals. When hooked up to a camera, they can be used to take time lapse images, bracket exposure lengths and precisely time long exposure images (over 30 seconds) that the built-in timer on the camera cannot normally generate. When hooked up to a flash, they can be used to create a strobe effect. Being this useful, there are many different DIY projects to make them.”

“Each slave normally runs in a infinite loop, sampling the LED sensors as fast as it can and storing their values in a memory buffer. When a polling request is received from the master, an interrupt is generated which branches out of the sampling loop. I2C commands are pretty complex on paper, but merely a matter of setting and clearing bits in the digital world, so at 20mHz the pic handles them with lightning speed.”

“Several years ago when I had the nerve to blow money on such things, I attempted to build a ’68 Volkswagen Beetle for The DARPA Grand Challenge. During that time I thought it would be fun to convert an RC car for self-guided operation. I bought the car from RadioShack for maybe $30, tore it apart, and promptly forgot about it completely.”

“I decided to build an autonomous flying robot about three years ago. I’ve converted RC cars to autonomous operation, so I thought that an RC helicopter might be a good place to start. I quickly discovered that the standard helicopter design would probably be too unstable in flight for my simple navigational and programming skills – but in searching the web I stumbled across the four rotor electric helicopter platform…and I was hooked!”

“I had a project which needed to have a lot of microcontrollers programmed. Surely I would have gone crazy if I had to go through and do each MCU by hand: program, encrypt, check, remove the MCU, No Way! This is mindless robot work. Thus this intelligent piece of aluminum, single-pass through, with five servo motors, and a little PCB sheet was born and the microcontroller burning robot came to be. ”

“It measures about 3cm x 1cm and is based around a 24pin ic holder. The notes are generated by software programmed onto a Picaxe 08M microcontroller which also has a small speaker mounted on it. It’s powered by a 9 volt battery.”

“Even in its “natural” state the OWI Edge Robot Arm is a pretty interesting toy. It comes with DC motors and a cable switch box that allows you to manually control 1) Grip, 2)Wrist, 3) Elbow, 4) Shoulder, and 5) Base. Prices for the unit are typically less than $40. The greatest thing about the OWI Edge Robot Arm is that you assembly it yourself so you understand it well and it is easy to customize.”
