Mid-power UV LED operates at 365 nm
https://www.electronics-lab.com/mid-power-uv-led-operates-365-nm/
A ceramic-based UV LED, the VLMU1610-365-135 from Vishay provides typical radiant power of 18 mW at 20 mA and 50 mW at 60 mA over a wavelength range of 362.5 nm to 370 nm. The silicone lens of the device enables extremely long lifetimes of up to 25,000 hour, compared to typical mercury lamp lifetimes […]
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 […]

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.
