This device captures the IP address of your network and it publish on site DynDNS.com. All without PC.  It allow a remote access to your LAN even if the IP address of the connections changes. If you don’t want to use the software provided by DynDNS, and then leave the PC switched on continuously, the [...]

Jaroslaw Lupinski designed Senpai (Extra Shield for Arduino Programming Nimble) shield to be easy to program AVR microcontrollers using Arduino.     [via]  

Laptop batteries can be repaired but such work only makes economical sense for smaller operators.The success rate varies with battery type.One must remember that the ‘smart’ battery consists of two parts, the chemical cells and the digital circuit.In some cases, the chemical part can be fully restored but the fuel gauge may become inaccurate or [...]

This “Tupperware Turret” is a highly modified airsoft pistol put onto a pan and tilt platform with a turret cover. It rotates, tilts up and down and has precise fire control. Control is done wirelessly with a generic TV remote control. Source: Chris

DorkbotPDX has made good project, Mykle called him for RGB LED lighting help and he helped Mykle for his lightbar. The basic idea was run all 3 LEDs in series. He ordered a few ASMT-MT00′s and other parts, and came up with a somewhat unconventional design.The ASMT-MT00 nicely provides each LED separately on 6 pins, [...]

Chris from pyroelectro  has made AV Test Box. This Box  includes displaying an 800×600 VGA test pattern as well as generating sound signals for testing audio systems. This video will you show what you can expect from this AV test box like the one built in this project and will show how quickly whether or [...]

Nice project from Petar , he send me some photos of his UV Box. This UV LED Exposure Box was published in the magazine Emiter, and here’s what the author says on this project. My UV box contains 54 ultraviolet 5mm LED distributed in a matrix of 9X6 leds.The box can enlighten board with maximum [...]

Here’s a project that shows you how to decode a tv remote control’s infrared (IR) signals and make your own IR receiver for it. The receiver decodes the infrared commands sent to it by a remote control, and displays them on an LCD for verification. Source: pyroelectro

How to get 5 volts from a higher voltage?  Of course by LM7805. The fact that the chip is the LM7805 linear voltage regulator. This means that all the excess stress she planted on his. That is, when an input voltage of 12 V, she is forced to provide for themselves a voltage drop of [...]

This mini protoboard you can use for a small project. With this board that you can start with some simple projects such as LED Flaser and progressing on to more advanced projects.   Source: b0j3

If you’ve ever been designing a circuit and had to experiment with different values of caps and resistors, you probably didn’t like it much. It can be a hassle to switch out components over and over, trying to find the right combination to suit your needs.  With RC filter circuits, it can be quite difficult [...]
