This is very cool project .USB interface is implemented by using PIC18F2550 microcontroller. Using USB LCD module you can view many types of information taken from PC like temperatures, time/date, MP3 song titles, view emails, RSS feeds – all that LCDSmartie or other program supports.

The circuit is based on low-cost AtTiny2313 ATMEL microcontroller. It is able to read 125KHz RFID tags. Every tag is read then decoded, and its code is transmitted as ascii chars on the serial output. If the RFID code read is the same that is recorded in the micro non-volatile memory, then a relay pulses for 1,5 seconds, acting as electronic lock. The code stored in non-volatile memory is taken from the FIRST tag that is read from the circuit after burning the micro. The downloadable zip file contains the schematic diagram, the printed circuit board layout (single face, PDF 1:1 format) and the object file to burn in the micro. you can download document RFID 125KHz

How to Avoid the dirty
When you are refilling an ink jet cartridges, you must do so through several newspapers, or better, an old rag or shirt. Kain will gather all the excess ink immediately and is easier to clean. Once used for refilling, dirty will not be a problem again.
How to Clean
First refill the inkjet printer cartridges, you may get a little ink on your hands. To get the ink off, wash hands with soap to remove any excess oil and use a light bleach and water solution. Then wash with soap and water to remove excess and bleach. After you use for this process, you do not need to get all the ink on your hands.
Castle Ink Cartridges take great care to provide you with only the highest quality remanufactured and compatible inkjet printer cartridges. All our inkjet cartridges are manufactured without compromise in an ISO-9002 certified manufacturing facility and batch tested to ensure consistency.

There’s a exercise bicycle have been abandoned in the garage, as you’re not longer needing it anymore? Would you believe that with some efforts, you could easily transform an unused exercise bicycle into a “Pedal Gun”?
When you refer to the above figure, all you can see here is the remarkable pedal-powered air gun! Hold on a second, you must think it’s impossible to build up this giant buddy. Well, believe it or not, it doesn’t as hard as you think here!
For your information, an exercise bicycle is used as the main component in this project. The compressor head is made from a small garage air compressor, which it has enough PVC to make something almost like an air gun. For making the pedal gun become even tougher, the bottom half of the gun is 4 feet of 2″ PVC, where is capped on the front and elbowed at the rear.
