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...

The TJA1042 of NXP Semiconductor is a CAN transceiver with high-speed capabilities that provides a physical link between physical transmission medium and the protocol controller. The transceiver is designed for high-speed (up to 1Mbps) CAN applications in the automotive industry,...

David Scheltema @ makezine.com compares the C.H.I.P computer with Pi Zero to find our which is the best option for your next project: Now that there are two capable, sub-$10 computers for Makers — the $5 Pi Zero and the $9 C.H.I.P. — the debate will rage online over which board...

FutureSharks @ github.com has build a very nice HiFi passive preamplifier controlled by an Arduino board. It has the following features: Volume control and input selection via encoder and Apple remote. Uses a 256 step R2R relayed based attenuator. Completely...

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...

blog.squix.ch has published there code for a ESP8266 based weather station. More details here: It is not yet working as smoothly as I want it to work but maybe some of you can help me getting rid of the nasty issues that were bugging me for the last few weeks. The README on github...

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...
