RTL8710 Is a New ESP8266 Competitor
https://www.electronics-lab.com/rtl8710-new-esp8266-competitor/
In the last two years, ESP8266 was the Wifi Chip/Module which dominated the market of hobbyists, even a lot of commercial products use ESP8266, due to the low price, ease of use and large community around ESP8266. RTL8710 is a Wifi network solution from the Taiwanese Company Realtek. It can operate independently, or as a […]
IEEE Ranking for Programming Languages – 2016
https://www.electronics-lab.com/ieee-ranking-programming-languages-2016/
Are you an embedded system programmer? Checkout the rank of your favorite programming language according to IEEE Spectrum ranking. C language is in the first place for programming devices controllers, followed by C++, Arduino, then Assembly. IEEE Spectrum has special methods to figure these ranks, for example they “measure the number of hits for each […]
TFoC: FPGA & Forth = VGA
https://www.electronics-lab.com/tfoc-fpga-forth-vga/
Here is a fun project, created from start to finish by Matthias Koch: In itself, this is no big deal. The generated pattern is a 16×16 expanded pixel image, and 640×480 displays are pretty basic by now – although they’re fine for presenting text-mode information and retro games. TFoC: FPGA & Forth = VGA – […]
Opto-isolated laser controller build
https://www.electronics-lab.com/opto-isolated-laser-controller-build/
Scott Harden built his own opto-isolated laser controller and wrote a post on his blog detailing its assembly: My goal was to utilize a free hardware output line to signal to a device that I build to modulate the laser in a special way. This way there would be no modification to any existing equipment, […]
App note: Solid-State Relays
https://www.electronics-lab.com/app-note-solid-state-relays/
Solid-state relays introduction from Vishay, (PDF) MOSFET SSRs feature an optocoupler construction, but have a pair of MOSFETs on the output instead of a phototransistor. A pair of source-coupled MOSFETs emulate an electromechanical relay by providing bidirectional switch capability and a linear contact. No output power supply is required.

MAX232: The classic IC lives on since 1988
https://www.electronics-lab.com/max232-classic-ic-lives-since-1988/
by Len Sherman @ edn.com: The June 23, 1988 issue of EDN included a Maxim Design News insert where we asked “Who in their right mind would choose a computer interface standard that uses ±12V supplies, requires expensive connectors, works over a limited distance, is error prone, difficult to network, and has no current loop […]
