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
Move over Segway this technology might spawn some cooler creations! “Our research goal is to gain a deeper understanding of how such dynamic agility can be achieved in mobile machines interacting with people and operating in normal home and workplace environments. We are developing novel dynamically-stable rolling machine and walking machine research platforms to study this issue. We will evaluate the efficacy of this type of dynamic locomotion in
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
Two MIT students might have a lucrative safe cracking career to fall back on if they don’t land jobs that interest them. 🙂 “I’m not referring to those telephone spamming machines that call you during dinner time or while you’re sleeping. This is robotic safe cracking. Two curious MIT students with a mysterious safe and a bit of free time built a laptop-controlled robotic fixture that opened a “manipulation proof”,
Nate True has made a very cool device that is controlled by a PIC microcontroller. The controller uses a strobe effect to make water drops look like they are running backwards! “It all started when my friend Jesse told me that if you get a strobe light fast enough, you can make it look like dripping water is going in slow motion or even backwards. This phenomenon happens because
I remember spending many countless hours playing games on the Atari 2600. You can still find some of the original consoles on Ebay or in garage sales. But if you want to hack the new Atari Flashback 2 console to play your vintage cartridges you are in luck, this article will give you the necessary information to get the job done. “So, you’ve decided to take your Atari Flashback 2
