Review: Siglent SDS 2304X oscilloscope


https://www.electronics-lab.com/review-siglent-sds-2304x-oscilloscope/

Jack Ganssle @ embedded.com reviews the Siglent SDS 2304X oscilloscope. I’ve had a Siglent SDS1102CML two channel 100 MHz bench scope here for the last two years. I demand a lot from my test equipment so had low expectations when it arrived. After all, how good can a $359 unit be? Turns out, quite a […]

The smallest camera module for mobile devices


https://www.electronics-lab.com/smallest-camera-module-mobile-devices/

Nidec Copal, the world’s biggest manufacturer of camera shutters, has developed the smallest, thinnest and lightest camera module for mobile devices. It measures just 8.5 x 8.5 x 4.2 mm and weighs 0.57 g. The new camera module is about half the size of Nidec Copal’s previous module. by Harry Baggen @ elektormagazine.com The new camera module has a 16 megapixel, 1/3.1″ […]

Your laundry is done!


https://www.electronics-lab.com/your-laundry-is-done/

Tinkerman @ tinkerman.cat tipped us with his latest project. It’s a laundry notification system that will message you when it’s finished. I often forget my wet clothing in the washer and after a day they really smell… so I thought about monitoring my washer and get a notification in my phone when the laundry is […]

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. App note: Solid-State Relays – [Link]

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 […]
