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...

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...

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...

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...
