32.768 kHz MEMS resonator is only 0.9×0.6×0.3mm

Measuring just 0.9×0.6×0.3mm (50 % smaller than a conventional 32.768 kHz crystal resonator), the WMRAG series 32.768 kHz MEMS resonator is the world’s smallest, claims manufacturer Murata. Murata Manufacturing Co., Ltd. (Head Office: Nagaokakyo-shi, Kyoto; Chairman of the Board and President: Tsuneo Murata) has developed the world’s smallest 32.768kHz MEMS resonator, which is expected to make a significant ...

DIY TV-B-GONE IS A-OK

Where won’t they put a TV these days? We’ve even seen one creeping behind semi-transparent mirror film in the ladies’ room of a sports bar, though that one didn’t last long. Up until that moment, we had never wished so hard for a TV-B-Gone, especially one as small and powerful as this DIY version by [Shane]. The best thing about [Shane]’s DIY TV-B-Gone is the strength of signal, though the size is nothing t ...

Femtosecond Electronics With Plasmonic Hot Electron Nano-emitters

A team led by the Technical University of Munich (TUM) physicists Alexander Holleitner and Reinhard Kienberger has found success for the first time in generating ultrashort electric pulses on a chip. They made this possible by using asymmetric metal antennas only a few nanometers in dimension, then running the signals a few millimeters above the surface and receiving them in a controlled way. Traditional el ...

WIRELESS TIN CAN TELEPHONE

For many kids, the tin-can telephone is a fun science experiment that doesn’t last much longer than it takes to tangle the string around a nearby tree. [Geoff] decided to go a different however, building a tin-can telephone that’s completely wireless. The build starts with a hacker favorite, the Arduino Uno. It’s hooked up to an microphone input board which uses the Arduino’s analog input to pick up audio. ...

Use a Comparator or Op-Amp to Simplify Light Dependent Resistor Output

If your project calls for light sensitivity, it’s hard to beat light dependent resistors (LDRs), also known as photoresistors. They’re available for a few cents each, and their resistance varies based on how much light they receive. In the dark, these devices produce resistances in the megohm range, and can fall to hundreds of ohms or even less when exposed to sufficient light. You first instinct when proto ...

LOGGING INTO LINUX WITH A 1930S TELETYPE

Buried deep within all UNIX-based operating systems are vestiges of the earliest days of computing, when “hardware” more often than not meant actual mechanical devices with cams and levers and pulleys and grease. But just because UNIX, and by extension Linux, once supported mechanical terminals doesn’t mean that getting a teletype from the 1930s to work with it is easy. Such was the lesson learned by [Curio ...

DIY Givi V56 Motorcycle Topbox Light Kit With Integrated Signals

https://youtu.be/xtSzXwfG3HA As a motorcycle rider, I'm all too familiar with being treated like I'm invisible on the road. One thing I always add to my bikes is a top box which usually has an integrated light. I recently upgraded to a new bike and bought the Givi V56 Monokey box since it had lots of space for items. This box has a spot for a factory light kit which consists of two strips of LEDs for each s ...
