433 ON A STICK

Cheap 433 MHz wireless switches are a tempting way to enter the world of home automation, but without dedicated hardware, they can be less easy to control from a PC. That’s the position [TheStaticTurtle] was in, so the solution was obvious. Build a USB 433 MHz transceiver. At the computer end is a CH340 USB-to-serial chip and the familiar ATmega328 making this a compact copy of the Arduino. At the RF end ar ...

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. ...

How to make precision measurements on a nanopower budget

Heightened accuracy and speed in an operational amplifier (op amp) has a direct relationship with the magnitude of its power consumption. Decreasing the current consumption decreases the gain bandwidth; conversely, decreasing the offset voltage increases the current consumption. Many such interactions between op amp electrical characteristics influence one another. With the increasing need for low power con ...
