The Tweet-a-watt [13] is a hacked version of the standard Kill-A-Watt Plug in Power Meter. By piggybacking on the device's on-board LM2902N op-amp chip, the creator was able to get readings for voltage and current and transmit to a computer, which then sent this to Twitter via handle @tweetawatt.

David L. Jones is an Australian video blogger. [2] [3] He is the founder and host of EEVBlog [4] (Electronics Engineering Video Blog), a blog and YouTube channel targeting electronics engineers, hobbyists, hackers, and makers.
Analog multimeter Digital multimeter. A multimeter (also known as a volt-ohm-milliammeter, volt-ohmmeter or VOM) [1] is a measuring instrument that can measure multiple electrical properties. [2] [3] A typical multimeter can measure voltage, resistance, and current, [4] in which case can be used as a voltmeter, ohmmeter, and ammeter.
EEV or EeV may refer to: . English Electric Valve Company, a designer, developer and manufacturer of electronic components and sub-systems; Enhanced environmentally friendly vehicle, a car category used in European emission standards
Both PICkit 2 and PICkit 3 have internal, switch-mode voltage regulators: from a 5 V USB supply at around 100 mA, the PICkit 2, generates 2.5 to 5 volts, and the PICkit 3 generates 2.5 to 5.5 volts. On both units, accuracy may be increased by calibrating the output with a multimeter.
Kolbe electrometer, precision form of gold-leaf instrument. This has a light pivoted aluminum vane hanging next to a vertical metal plate. When charged the vane is repelled by the plate and hangs at an angle.
An 11-year-old girl has been found clinging to tire tubes off the Italian coast after the migrant boat she was on sank three days earlier.
For example, a meter with a sensitivity of 1000 ohms per volt would draw 1 milliampere at full scale voltage; if the full scale was 200 volts, the resistance at the instrument's terminals would be 200 000 ohms and at full scale, the meter would draw 1 milliampere from the circuit under test. For multi-range instruments, the input resistance ...
