Integrated Load Switches versus Discrete MOSFETs
https://www.electronics-lab.com/integrated-load-switches-versus-discrete-mosfets/
Alek Kaknevicius @ ti.com discuss about load switches and the advantages of intergrated switches over discrete ones. The most common approach to load switching solutions is to use a Power MOSFET surrounded by discrete resistors and capacitors; however, in most cases using a fully integrated load switch has significant advantages. While both discrete and integrated […]

https://www.electronics-lab.com/arduino-easy-module-shield-tutorial-best-arduino-shield/
Our friends on educ8s.tv uploaded a new Arduino tutorial. Let’s check it out. Dear friends welcome to another Arduino Tutorial! Today we are going to take a first look at this very promising new shield for Arduino, the Arduino Easy Module Shield! Also we are going to build a couple of projects with it. Let’s […]
Water Out Of Thin Air
https://www.electronics-lab.com/water-thin-air/
Due to the advances of technology, we are able now to produce water out of thin air without using the resources usually applied like mains utilities. Such approach would be perfect in places that lack natural resources like deserts. Working from the effects of direct solar radiation, a group of researchers at UC Berkeley had designed such […]
Soldering pen for Weller RT tips with OLED display
https://www.electronics-lab.com/soldering-pen-weller-rt-tips-oled-display/
vlk @ hackaday.io build a very nice soldering pen with a OLED display. I found some projects where is used Weller soldering tips designed for WMRP soldering iron with standard 3.5mm jack and inside the tip is also thermocouple for sensing temperature. These tips are not so cheap but the quality is really great, especially […]

ThomasVDD @ instructables.com writes: A while back I built a powersupply from an old ATX PSU, and while it works great, I wanted to step up my game with a digital powersupply. As already said, it is powered by batteries (2 lithium cells to be precise), and it can deliver a maximum of 20 V […]
Orthrus – SD card secure RAID USB storage
https://www.electronics-lab.com/orthrus-sd-card-secure-raid-usb-storage/
Nick Sayer @ hackaday.io build a SD card RAID USB storage board. He writes: This project is a hardware mechanism to provide secure “two man control” over a data store. It is a USB microSD card reader, but it requires two cards. The data is striped in the style of RAID 0, but the data […]

The remote stations communicate wirelessly with the gateway using LoRa radios. LoRa IOT Home Environment Monitoring System – [Link]
Spectrum Next, A New of ZX Spectrum
https://www.electronics-lab.com/spectrum-next-new-zx-spectrum/
In 1982, the UK’s best selling computer, ZX Spectrum, was released by Sinclair as 8-bit personal home computer highlighting the machine’s color display. And today, a group of makers are introducing the Spectrum Next, an updated and enhanced version of ZX Spectrum. The Spectrum Next is fully compatible with the original one. It has been enhanced to provide a […]
PICTIL – Remake of the TIL311 hex LED display
https://www.electronics-lab.com/pictil-remake-til311-hex-led-display/
Yann Guidon @ hackaday.io rebuild the TIL311 hexadecimal display using a pic microcontroller. He writes: The TIL311 is a nice but expensive, obsolete, power-hungry hexadecimal display. It would be cool to make a tiny module with similar functionality which solves its shortcomings. A 20-pins PIC is a solution but other decoding chips could work too. […]
