IoT enabled background radiation monitoring device

DIY Geiger counter projects are very popular among hobbyists. Geiger counters are used to detect beta particles and gamma rays radioactive emissions.They all use a Geiger-Muller (GM) tube, which is a glass tube filled with an inert gas such as helium, neon, or argon at low pressure, to which a high voltage is applied. The tube becomes conductive of electricity when it is impacted by a high-energy particle or photon. We have seen radiation monitor builds before based on 555 Timer IC and ESP8266. Brett Oliver‘s IoT enabled Radiation Monitor is Arduino-based and WiFi-enabled using ESP8266 and it continuously monitor the surrounding radiation and log the

Arduino Flappy Bird game

Dejan Nedelkovski from How To Mechatronics explains in this tutorial how to replicate the Flappy Bird game using an Arduino board and a TFT touchscreen. Here’s the working principle of game: we have 50 pixels wide pillars which move from right to left and every next pillar has a different random height. In order to make them moving, logically, after each iteration we need to clear the screen and redraw the graphic with the pillars at their new position. However, we cannot do that because of the low refresh rate of the screen, which would cause flickering of the graphics. In

DIY telescope controller based on Arduino Due

GoTo telescopes are very desirable among stargazers because of their ease to use. They are powered with microprocessors and bunch of motors to allow automatic access and tracking of sky objects with a handheld remote or a smartphone app. rDUINOScope is an Open Source, Arduino Due based Telescope Control System (GOTO) that uses database with THE BEST ~250 stellar objects ( Messier and Hidden Treasures Catalogues) and 200 stars, calculates their position on the sky and points the telescope. With a TFT touchscreen display, it is a standalone controller. It also supports Bluetooth and LX200 protocol to connect and be controlled by smart

Arduino guitar pedal

This Arduino-based multi-effect guitar pedal is an open source design for guitarists and hackers. The design is made simple and customizable so that you can program it to make your own effect without an in-depth knowledge of digital signal processing. The project is Open Source & Open Hardware and aimed for guitarists, hackers and programmers that want to learn about digital signal processing, effects, synthesizers and experiment without deep knowledge on DSP, electronics or hardcore programming.

Making a self-balancing robot using Arduino

Two-wheel self-balancing robots are pretty cool and could be challenging to make for beginners. Joop Brokking describes the build process of his amazingly stable self-balancing robot in a video tutorial posted below. The robot uses two stepper motors for precise motion that is controlled by an Arduino board. The angular inclinations data are derived using a MPU6050 gyro/accelerometer. You can download the design files and firmware from Joop’s website. Joop’s YouTube video tutorial is posted below:
