DIY telescope controller based on Arduino Due

Posted on by Leave a comment

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

Another ESP8266 internet clock using LED matrix panels

Posted on by Leave a comment

Internet has made it easy for computers to synchronize their clocks to an accurate clock value generated by a remote server. We discussed earlier how to make ESP8266-based internet clocks that utilizes National Institute of Standards and Technology’s (NIST) NTS service to retrieve accurate time information and display it on a 4-digit seven segment LED display and on a TFT display. This article from Ayzenberg describes a similar ESP8266-based internet clock that displays time on a large 16×72 LED matrix panel. It also features APIs for displaying messages or setting the display brightness.

ZeroBot: A FPV robot controlled by RPi Zero

Posted on by Leave a comment

Max Kern introduces ZeroBot, a Raspberry Pi Zero W based FPV robot that can be controlled over a WiFi access point (no router is required). With an integrated camera module, it provides you a live video feed with minimal latency. It can be controlled using any computer or smartphone via a web browser. The body parts and the wheels are made with a regular 3D printer. Some of the key features are: – Compact CAD design with 3D printed components – Analog control via a joystick (and multitouch) – Simple battery solution using only a standard power bank – Low

Weather forecast cloud

Posted on by Leave a comment

There are already so many weather station projects based on Raspberry Pi. This Instructable describes a weather forecast project based on Raspberry Pi zero with a unique cloud-shaped display that connects to the Yahoo Weather API to retrieve weather info and changes the color of the cloud in accordance with the forecast for the next day. The cloud display uses Neopixels strips for changing colors.
