In an article “Symantec warns: each word or phrase that you enter on the wireless keyboard, can be tracked!” Was called I knew it was true, but such a project would never have thought I’d reached on the web
Circuit else is going on what is written in the wireless keyboard can be sent to computers for most of our tests uses a “microsoft wireless multi media” is done on the keyboard
Wireless Keyboard SPY
Wireless keyboard spy circuit ATmega-64 based on the usb link with the can be made sd card division, guess computer connection when it is not on the card data is written wi-fi antenna input, though there was a, we use the keyboard, the signal is very weak, but the circuit with a powerful antenna is connected happens wonder
All details have been shared source code files, etc. şema.pcb eagle. uygulamasa who work on the project with ATmega64 usb for communication, literacy issues sd card can sample codes feyza ready to PCBs may be edited for different projects drawing

PWM TL494 Boost Converter Circuit DC DC 12V to 25V
DC to DC converter circuit size and quite a lot of small passive components used PWM control TL494 SMD type
Matchbox output coil in comparison with the size of the image of the PC power supply-12v -5 volts output the same as in the core of filter coil (the coil can not be found alternatives to the song)
# Input Voltage – 12V to 15V DC
# Output voltage – 15V .. 25V
# Maximum Efficiency – 88%
# Maximum Power Output – (Uwe 5.5 x). 66W 12V to 14V, Pmax = 77W
# Output Current Continuous – i19v 12-14V, Imax = 3,5-4A
# Operating Frequency – 200kHz. 100kHz
