The Reflow Master Shield from Paladin Enabling Technologies is an Arduino shield that turns your normal toaster oven into a reflow oven. A reflow oven is used in the production of electronics to change solder paste from a paste form to a liquid form and lastly to a solid form. This results in all your

Recent advances of Li-Ion battery technology could be the kick start the faltering electric vehicle market needs for it to go main stream. As well as the fast charge time the new battery can be cycled more than 10,000 times and has a lifespan of 20 years. The work carried out at NTU Singapore replaces the
Li-Ion battery recharges to 70% in 2 mins Continue Reading
A temperature data logger, is a portable measurement device that is able to recording temperature over a defined period of time automatically. The data can be retrieved and viewed after it has been recorded. in this device the temperature will record every one minutes in CSV file. Step 1: You Will Need 1- Arduino Nano.
Temperature Data Logger Continue Reading
The Wifi Arduino 85 is a small board with ESP8266 -01 module, Attiny85 micro controller and a relay. It Also has and additional header for connecting an external relay or to connect sensors like PIR, IR etc depending on your application. If you are a tinkerer you will also be able to connect a HC-05/06
The Geiger–Müller counter is a relatively simple tool to measure ionizing radiation. To increase sensitivity, construction presented here contains three (instead of one as usually) soviet STS-5 lamps. This is important for measurements of natural sources of (low) radiation like soil, rocks (an article about my trip with Geiger–Müller counter on Śnieżka mountain). Principle of
Geiger–Müller counter that can work with Arduino or (almost) any evaluation board Continue Reading
What is Pozyx? Pozyx is the first affordable and easy-to-use hardware solution that provides accurate indoor (and outdoor) positioning and motion information for Arduino. In order to achieve a positioning accuracy of a few centimeters, the pozyx system relies on a novel wireless radio technology called ultra-wideband (UWB). The accuracy achieved with this ultra-wideband technology
