Tsunami is a signal generator built on the Arduino platform. It is the brainchild of London-based developer Nick Johnson at Arachnid Labs and has secured funding on Kickstarter for its commercial ...

[Todd Harrison] really has our number. Like him, we don’t want to spend money when we don’t have to, and hacking our own solutions is a lot more fun anyway. This time around he’s helping out a friend ...

The TB-007 smart robot is equipped with a metal detector and is based in an Arduino with a motor shield which has the ability to control the two main motors, including a stepper motor and three servos ...

I designed the circuit in Figure 1 as a part of a data transmission system that has a carrier frequency of 400 kHz using on-off keying (OOK) modulation. I needed to detect the presence of the carrier ...

French developer is looking for support amongst the Arduino community for his crowd-funding project – an Arduino compatible high precision frequency counter. Thierry Guennou, writes: “The concept of ...

It has been proposed that high-frequency detectors based on the so-called spin-torque diode effect in spin transfer oscillators could eventually replace conventional Schottky diodes due to their ...
