DIY SWR and Power Meter
https://www.electronics-lab.com/diy-swr-and-power-meter/
diycrap.blogspot.com has build a SWR and power meter based on Arduino Nano and LCD display: First of all, this SWR meter in this article is not exactly homebrew, as I based the circuit on the schematic in the excellent book Arduino Projects of Amateur Radio. Although I bought the book and respect the copyright of […]
Nandland Go Board – Your FPGA Playground
https://www.electronics-lab.com/nandland-go-board-your-fpga-playground/
There’s a new FPGA development board on Kickstarter. It’s called the Nandland Go Board, and it aims to be an inexpensive, easy-to-use FPGA development board to learn about how FPGAs work and what they are capable of. This board is unique because it provides a lot of options for projects built directly into the board. […]
