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
I can see these fire fighting robots being positioned on street corners ready to spring into action when needed. “This firefighting robot presented in July 2006 has many advantages among others, as: -It is four times more powerful in its traction system; -It has Fault Tolerant Architecture with redundancy in its moving system; -It has lighting system; -It was constructed completely modular; -It has at least 100 % more autonomy,
MiniFlash sent in some pictures of his latest creation. It is a LEGO sniper rifle that is sure to pack a punch.
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
These Shreddding Scissors are a cool idea. They can be put to good use until you get a USB powered paper shredder. Via: Seihin-World
We all remember the old style ant farms… This new version looks nothing like the old ones, someone needs to set up an ant cam using one of these things. 🙂 “Fascinating creatures ants. Sure you hate to see them in your socks or making a B-line for that pizza crust crumb you forgot to sweep up at the local LAN party. But let’s give credit where credit is due.
