If you are looking to do some covert key capture this DIY Wireless Keylogger could be a project you may want to consider. "The Wireless Keylogger consists of two main building blocks: the transmitter, and the receiver. The actual keylogging takes place in the transmitter, which is in fact a PS/2 hardware keylogger, with a built-in 2.4GHz wireless module. Captured keystroke data is transmitted through the radio-link in real-time, rather than getting stored. The receiver on the other hand, is a wireless acquisition unit with a USB interface. All keystroke data received from the transmitter is sent to the host computer via USB. From the software side, this data is available through a virtual COM port, allowing any terminal client to be used for visualizing keystroke data. The Wireless Keylogger electrical circuit is composed of two main building-blocks: the AT91SAM7S64 microcontroller and the nRF2401 transceiver. The accompanying passive components are mainly oscillator and RF circuitry. The entire circuit is powered with 3.3V, generated by the MCP1700 regulator and filtered by a set of capacitors. Power is drawn directly through the PS/2 bus (transmitter), or USB (receiver)."

There’s no good reason to make or use one of these!!!

What about using this as a way to connect any wired ps/2 device to a system wirelessly? Say, for example, as a way to have input devices available when you dont want your actual computer exposed? Before you say “there’s no good reason to make or use one of these”, think through potential uses - you might be surprised what needs people have, many of which could be considered “good reasons”.

“The actual keylogging takes place in the transmitter, which is in fact a PS/2 hardware keylogger, with a built-in 2.4GHz wireless module.”
That doesn’t sound very DIY. They basically just found something that did what they wanted and built a new receiver. Am I missing something?
