If you like both electronics and PC Car Racing games you’ve gotta have this gadget. On the latest version the author used a nice 4 needle gauge, and the result neat. You will definitely improve your gaming experience with one of these. Its not cheap though and you’ll have to know something about micro-controllers to build it. The actual project also features control buttons in case you need some extra buttons on your controller.
Remember the Gmail Light Cube notifier ? This is another project that displays the status of your email inbox, but this time trough an RGB LED. So you can setup 3 types of email notifications like work email in red, newsletters in green, other in blue. The color and characters are controlled trough RS232 by a Python script that runs as a scheduled task every 10 minutes, and the circuit is powered by a Picaxe 08M. The author didn’t provide a link for source code download, but he writes that he will send the code to anyone who asks.
This is a physical hit counter.It is used to count page-hits on the website instead of using software only.The counter will be connected to rs232 port through a few of electronic components that performs as a counter driver and power supply circuit. The circuit is based on MAX7219 and 7-segment common cathode LED display x 8 digits. MAX7219 is a 8-Digit LED Display Drivers with serial interface which makes it ideal for this project and really easy to implement.
I will sure build one of these for myself, with some minor tweaks, it will look great on my desk . I will write about it in a following article so Subscribe by RSS or email to get the news from this blog.
This is a small device designed to receive and transmit PS2 commands. The ATmega168 can receive PS2 commands from a mouse or keyboard and pass them out to a terminal or computer. Power is obtained from the computer or terminal over PS2. This device was originally designed to count the number of keystrokes in our Key Counter tutorial. A good, simple development board for the ATmega168 and the PS2 protocol.
I wish i would of presented this project earlier, since it is such a great prank for April the 1st, better luck next year with this prank. The bug based on a ATTiny45 micro-controller was designed to be plugged in into an available USB port, and to remain there unnoticeable. The bug than takes control of the caps lock function turning it on and off. You must imagine that the person sitting at that computer will go nuts trying to figure what’s happening. The bug is versatile and can be reprogrammed to take control of any key you wish.
. I will write about it in a following article so
