ESPUSB – An USB Software Stack For ESP8266
https://www.electronics-lab.com/espusb-usb-software-stack-esp8266/
ESP8266EX and even the new ESP32 SoC lack a USB hardware transceiver, so [CNLohr] decided to develop a USB software stack for ESP8266. After a quick search, I think it is the first try to do a USB software stack for esp8266. USB software stack is a firmware-only implementation of a USB. ESPUSB works in […]
Power supply IC packs eight buck regulators
https://www.electronics-lab.com/power-supply-ic-packs-eight-buck-regulators/
Aimed at systems requiring multiple low-voltage supplies, Linear Technology’s LTC3374A can be configured to supply two to eight independent regulated outputs with 15 possible output-current configurations. Each of the eight synchronous 1-A buck converters is powered from an independent 2.25-V to 5.5-V input supply. Output voltage range is 0.8 V to VIN. by Susan Nordyk […]
Rail-to-rail step-down regulator sinks/sources ±5A from 0V to 14.5VOUT
https://www.electronics-lab.com/rail-rail-step-regulator-sinkssources-%c2%b15a-0v-14-5vout/
LTC3623 is a ±5A high efficiency, current mode synchronous buck regulator that is adjustable from 14.5V down to 0V output with a single resistor. Its architecture uses a 50 µA current reference, combined with a single resistor, to set the output voltage. by Graham Prophet @ edn-europe.com The LTC3623’s 4V to 15V input voltage range […]
DIY Lorentz Force Experiment
https://www.electronics-lab.com/diy-lorentz-force-experiment/
Fabian Gebhart shared his Lorentz Force experiment on Thingiverse: Don’t you love it? Magnetism? Electronics? And 3d printing? In this project I combine all of them together to a little but spectacular do-it-yourself experiment. With just a few components and the 3d printed part you will be able to build your own Lorentz Force Experiment. […]
ams AS1383 A 200mA, 3.5MHz DC-DC Boost Converter
https://www.electronics-lab.com/ams-as1383-200ma-3-5mhz-dc-dc-boost-converter/
If you have a single Li-Ion battery powered application, then you need to think about using AS1383 in your design. AS1383 is a DC-DC boost converter comes in a 6-pin WL-CSP package with 0.4mm pitch, a very small package suits the limited space applications. In the below image, you can compare the WL-CSP package with […]
It’s the end of C as we know it!
https://www.electronics-lab.com/end-c-know/
beningo.com discuss about the future of C language and it’s use in embedded systems. The C programming language has been with embedded software developers since its creation in 1972. Ever since then C has been a blazing constant, surviving even the big push in the late 90’s and early 21st century to move to C++ […]
Bi-Directional Voltage Level Translator
https://www.electronics-lab.com/bi-directional-voltage-level-translator/
Lukas Fassler from Soldernerd shares his experience designing a bi-directional voltage level translator and manufacturing the board with DirtyPCBs. While most of my microcontroller designs run on 3.3 volts there is still the occasional 5 volt design. Or I do something with an Arduino. So the need may arise to interface between logic working at different […]
Cheap homemade 30 MHz – 6 GHz vector network analyzer
https://www.electronics-lab.com/cheap-homemade-30-mhz-6-ghz-vector-network-analyzer/
Henrik Forstén has done amazing job designing a homemade vector analyzer with the goal to fit it’s budget of 200EUR. The design is open source and available on github. Vector network analyzer (VNA) are used to measure scattering parameters of high frequency circuits. When frequency is high enough the reflections of the waves start to […]

Siglent oscilloscope SDS1102X review
https://www.electronics-lab.com/review-siglent-oscilloscope-sds1102x/
Harry Baggen @ elektormagazine.com reviews the Siglent SDS1102X oscilloscope. Before we take a look at the instrument itself, I would like to say something about the characteristics of an oscilloscope for ‘small users’. What do you really need for your daily tasks? Even the cheapest models from Chinese manufacturers already have a sample rate of […]
