Control accurate incremental voltage steps with a rotary encoder
by Anthony Smith @ edn.com: Experimenting with an HF oscillator, I needed to control the varactor diode voltage in precise increments over a 2V-10V range. A buffered potentiometer was the obvious choice, and connecting two pots in series to give coarse/fine control (or using a...

MagSpoof – Wireless credit card/magstripe spoofer
MagSpoof is a device that can spoof/emulate any magnetic stripe or credit card you currently own. It can work "wirelessly", even on standard magstripe/credit card readers, by generating a strong electromagnetic field that emulates a traditional magnetic stripe card. Note: MagSpoof...

Raspberry Pi tutorial: Use SSH to in order to remote control your Raspberry Pi
SSH protocol can be very useful if we want to remote control our Raspberry Pi. I am using a Raspberry Pi A+ board in this video but you can use any Raspberry Pi board you like. So far, when we wanted to use our Raspberry Pi, we were using a keyboard, a mouse and a monitor via the...
