Amplifier requires no dc bias
https://www.electronics-lab.com/amplifier-requires-no-dc-bias/
john guy @ edn.com writes: Intrinsically capacitive transducers and other high-impedance signal sources usually require ac coupling and a buffer amplifier to condition the signal for further processing. Buffers take many forms, but most of them compromise signal quality through the use of external resistors that provide a dc path for the input bias current. […]

Body Heat Provides Wearables With Eternal Power
https://www.electronics-lab.com/body-heat-provides-wearables-eternal-power/
The first watch to make use of the body’s natural heat to uphold battery charge in wearables is now even being crowdfunded on Indiegogo. Who else but researchers from Texas A&M University (a hot place) came up with the solution. In today’s wearables battery life is a bottleneck, as increasing amounts of technology gets packed into lightweight designs comfortable enough for everyday wear. That’s why Texas A&M professor Choongho […]

Arduino 433Mhz RF Wireless Data Transfer
https://www.electronics-lab.com/arduino-433mhz-rf-wireless-data-transfer-2/
runtimeprojects.com has a tutorial on how to use 433Mhz modules to communicate between 2 Arduinos. The most practical and cool way of sharing data from 1 Arduino to another is by far using a radio transmitter and receiver. The simplest form of wireless transmission (I could find) is the 433Mhz ASK modules. They come in […]
5V Regulator Cap for 9V battery
https://www.electronics-lab.com/5v-regulator-cap-9v-battery/
David Cook built a 5V regulator to sit atop a 9V battery: For quick portable projects and temporary hacks, it is often faster to reuse a simple 5V regulator circuit than to integrate a power supply into the device design. My toolbox has an LED tester and magnifier light, so why not add a convenient […]
