This DIY orb by UK-Dave reminds me of the orb made by Ambient Devices. Dave has taken about $60.00 of electronics to create a device that can be remotely controlled from a computer. All the source code for the PIC based microcontroller is available on his site. “The Orb is my attempt at building an ambient interface. It consists of a number of high-brightness red, green and blue LEDs, a
The LPC2103 microcontroller from Philips sounds too good to be true. All the specs listed below for $5.00. The guys over at TRAXMOD have used it to create an audio player. “TRAXMOD is a small digital audio player using the Philips LPC2103 ARM7TDMI-S high speed microcontroller chip (prior versions were based on Microchip dsPIC DSPs). Currently, the ARM port can play raw wave audio streaming off of a FAT formatted
Unlike the video car that was featured yesterday, this one by Ryan Robinson was built from scratch using some common parts. The results are fantastic! “This weekend I happened to come into possession of a $170 store credit to one of the better hobby shops in the area. Not being into RC cars or planes I figured I’d just nose around and see if anything struck my fancy. Well,
Tired of replacing burnt out dash lights? Why not replace them with LED lights, you will never have to touch them again. 🙂 “Now you will need to assemble your LEDs. Take an LED and figure out what side is positive and the other negative. The longest leg of an LED is positive (anode; a), and the shortest leg is negative (cathode; k). Another way of checking which side is
This project is a number of years old but it is a great resource. Full schematics and code are provided so that you too can enjoy building an altimeter for your rocket. "I’ve been interested in model rocketry for a long time, but as my interest in electronics became stronger and more developed, rockets fell by the wayside. Recently, though, I thought of a way that I could combine these
Here is a simple DIY project that makes a cool LED flasher circuit. Check out this site for more information including full schematics and other diagrams. “Five pins from RA0 to RA4 are used as the input pin. These pins are pull-uped with 10K ohm resisters. So, when a switch isn’t pushed, the input becomes H level ( +5V ). and when a switch is pushed, it will become L
These iPod Speakers are not the type of speakers you can use anywhere since they are made from glass but they are much better looking than the standard types. “These are remote iPod speakers I scratch-built for my wife’s iPod shuffle. It’s all scientific glass and aluminium construction. The sub-woofer is an inverted glass dome, and a fresnel lens from a rail-car. The guts of the thing is borrowed from
