Arduino based Solar Tracker – Stepper Motor & Light Resistor Tutorial
In this project, we will be building a simple solar tracker capable of detecting the most optimal position of the sun on one axis and adjusting itself accordingly. The goal is to create a control loop which will be able to accurately position a solar panel toward the sun.
Soldering Station RT1: Portable, Hot, Rad
Portability is a big draw here. The open source soldering station RT1, created by Riccardo Pittini, offers some pretty handy features to boot.
The easy to use and portable soldering station has a simple design that uses an external power adapter with a rating of 12V/5-10A. It can also run on 7-24V batteries. Compatible with Weller RT tips, it has a 1.8” TFT full color LCD screen with two independent channels. It’s fully programmable for preset temperatures ranging from 150-450C. The micro-USB port provides required firmware updates (Arduino Pro Micro 5V 16MHz) and can be used for serial monitoring, parameter tuning and debugging.
The New RG350M – All Metal $130 Retro Gaming Handheld
The RG350M is the follow-up device to the wildly successful RG350 retro gaming handheld by Anbernic. The 350M comes with a redesigned layout, an aluminum alloy body, and a 480p IPS display. All of this comes in at just under $40 dollars more than the original selling price of the first RG350.

Make a Non-Contact Infrared Thermometer with IR Temperature Sensor
When debugging an electronics circuit or testing a new hardware design, often times I tend to check if the components on the board are getting hot abnormally by touching them. And if something is messed up (which usually is in the first try) these components could get as hot as 80°C or more burning not only the component but also my finger along with it. After burning my fingers for more times than I could remember I decided to build my own Temperature Gun using Arduino and an Infrared Temperature Sensor. This Thermal gun will be built using a non-contact temperature sensor called MLX90614; hence it can not only be used to measure component temperatures but can also be used for measuring body temperature, surface temperature, Heat ventilation and much more. Of course, these thermal guns are readily available in the market from renowned manufacturers like Fluke, Flir etc. But they are not light on your pockets and on top of that what is more fun than building your own gadgets. So let’s get started…
