‘Circuit Cobbling’ the Riffle Data Logger
https://www.electronics-lab.com/48276-2/
John Keefe has designed an open source data logger that is able to monitor conductivity, temperature and turbidity of water in lakes and fits inside a plastic bottle. The board is designed to monitor the conductivity (and, possibly, contamination) of water in lakes and streams, with the wonderful feature that it fits through the mouth […]
Get ready for MPLAB Express
https://www.electronics-lab.com/get-ready-for-mplab-express/
Chas from iradan.com discuss about MPLAB Express, the new cloud IDE from Microchip for PIC microcontrollers. He writes: I credit the maker movement with bringing electronics back from the crusty old and lonely electronics hobby back into the main stream. The Arduino is the micro of choice for this army of makers and I conceded […]
Monolithic linear battery charger operates from inputs up to 60V
https://www.electronics-lab.com/monolithic-linear-battery-charger-operates-from-inputs-up-to-60v/
Joshua Yee @ edn.com discuss about LTC4079 250mA Linear Li-Ion Charger IC that can be powered with voltages up to 60V. For charging relatively low capacity batteries, or maintenance charging backup and keep-alive batteries, linear topology battery chargers are valued for their compact footprints, simplicity and affordability. Even so, there is a dearth of linear […]
LT8391 – 60V Synchronous 4-Switch Buck-Boost LED Controller
https://www.electronics-lab.com/lt8391-60v-synchronous-4-switch-buck-boost-led-controller/
The LT8391 is a synchronous 4-switch buck-boost LED controller that regulates LED current from input voltage above, below, or equal to the output voltage. The proprietary peak-buck peak-boost current mode control scheme allows adjustable and synchronizable 150kHz to 650kHz fixed frequency operation, or internal ±15% triangle spread spectrum operation for low EMI. With 4V to […]
