Increasing cable length in precision video applications
https://www.electronics-lab.com/increasing-cable-length-in-precision-video-applications/
Maurizio tipped us about his latest article. In this article he talks about the different ways of transmitting video signal over large distances. He writes: Traditionally, the physical environment for transmitting video signals over long distances has been the shielded coax cable. Its quality and advantages are well known, and many times designers looking for […]
XLR8: Arduino-compatible FPGA-based Application Accelerator
https://www.electronics-lab.com/xlr8-arduino-compatible-fpga-based-application-accelerator/
XLR8 has both an ATmega328 clone and custom accelerator blocks on an FPGA and uses the standard Arduino IDE for programming. XLR8 is a drop-in replacement for an Arduino Uno, but with a twist. It is an Arduino-compatible board that uses a Field-Programmable Gate Array (FPGA) as the main processing chip. The FPGA provides a […]
AVR Programmer Shield
https://www.electronics-lab.com/avr-programmer-shield/
ohneschuh @ instructables.com has build a Arduino Shield that is able to program spare ATmega328 and ATtiny85 mcu using the ISP sketch. Beside my Arduino instructables I also use pure ATmega328 and ATtiny85 microcontrollers. To program them I normally used a breadboard and the ArduinoISP setup with an Arduino UNO or NANO. But this was not the […]

Single Regulator contains buck and boost controllers
https://www.electronics-lab.com/single-regulator-contains-buck-and-boost-controllers/
Linear Technology Corporation introduces the LTC7812, a dual output (boost + buck), low quiescent current synchronous DC/DC controller. When cascaded, its independent step-up (boost) and step-down (buck) controllers regulate the output voltage from an input voltage that can be above, below or equal to the output voltage, maintaining output regulation during cold crank and load […]
