Tobozo Tagada incorporated the uArcade Space Invaders game (Arduino playform) to ESP8266 with a nice buckle box enclosure. It uses a WeMOS D1 Mini Pro board for ESP8266 and a SH1103 based 1.3inch OLED screen for display. The original uArcade code can be found here.

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

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

E-paper displays are new innovative commercial displays that resembles ink on paper, requires ultra-low power, and can retain the image displayed even in the absence of power. Frank Buss‘ entry to 2017 Hackaday Prize contest is a solar-powered e-Paper display driven by ESP32/ESP8266 and a sticky magnet on back that can be used as a sticky note on a fridge to display important information over WiFi. Frank writes, The amazing thing about ePapers is that the image lasts without power forever (I tested it for months), and the contrast is very good. The idea is to build a small device

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
