    rDUINOScope Boiana is an open-source free-software and hardware telescope controller (GoTo) system, licensed under the terms of the GNU General Public License version 3. It runs on Arduino DUE controller connected to the shield board, which controls any German Equatorial Telescope Mount with steper motors.

    The system uses Open-loop controlling mechanism to control NEMA 17 stepper motors for the Right Ascension and Declination axis, and it can be easily adjusted to use any steppers and even commercially available products like Meade, Sky-Watcher, Vixen and etc. As such, rDUINOScope can be used as a replacement of the original controllers.

    rDUINOScope utilizes Bluetooth communication (Wire Free SetUp) to connect with all electronic devices and accept commands based on MEADE LX200 communication protocol.

    Commercial "out-of-the-box ready" version of rDUINOScope Boiana was created by a third party in 2017,[3] which spares the hustle of one to build the hardware themselves. It is good for people with less knowledge and experience in electronics.

    rDUINOScope Boiana become a “Featured Project” on HACKADAY.IO in 2017 and in the same year it won semifinals in three different categories of the Hackaday Competition: 1) 2017 Semifinalists, Internet of Useful Things;[4] 2) 2017 Semifinalists, Wheels, Wings, & Walkers;[5] 3) 2017 Semifinalists, Best Product.[6]

    rDUINOScope Boiana was created by the Bulgarian programmer Dessislav Gouzgounov, who launched the project in 2015.[7] The first stable version (v1.9) was published in May 2016[8] and a project website with BOM and Instructions was created: rduinoscope.byethost24.com. Later the same year, a Support Group on Facebook[9] was created to help amateur astronomers in building their own versions.

    In 2017 rDUINOScope Boiana code base has been upgraded on few occasions rieaching v2.3.1 on 3 August 2017.[10] With this version the Hardware has also been slightly modified[11] to add functionality like:

    • Brings all existing flavors of the hardware to use same code!
    • Screen Brightness control;
    • Screen Auto OFF function with timeout;
    • Implemented FET transistor to control power to the stepper motors;
    • More BlueTooth commands added to prepare for a screen less version (or operation);

    At present (Jan 2018) there are two known branches of the original code made by Giacomo Mammarella[12] and Khairey Nouhe,[13] to address specific changes in the original hardware design.

    Also in 2017, a third party developer Otto Winter created pre-built version of the hardware for sell. It is working out of the box and spares building the hardware part.

    Flavours of rDUINOScope[edit]

    There are two main ways one can get rDUINOScope Boiana: 1) Do-It-Yourself (DIY) Version and 2) Pre-Built Version. Initially, they had differences in the Hardware and thus the Software, but from v2.3.1 these differences were addressed and now both use the same Software and support the same features.

    Do-It-Yourself (DIY) Version
    The project was originally created as a DIY project, allowing amateur astronomers to create a highly customizable and feature rich telescope controller system (GoTo). Full set of Instructions and Bill of Materials are uploaded on the project website in 4 easy steps.[14]

    • Step 1 Explains the background of the work expected;
    • Step 2 Presents a list of materials one will need as well as instructions about Arduino IDE for the software;
    • Step 3 Explains the actual build, schematics and wire connections;
    • Step 4 Explains the final phase;

    At present (Jan 2018) there are two sub-flavors of the DIY project, dealing with different TFT Screens (Adafruit 3.5" SPI TFT and ILI9488 display in SPI mode).[15] Both clones of the software address the TFT screen as the original is very hard to find.

    Pre-Built Version
    Fully functional out-of-the-box! Best for people who don’t fancy DIY work, but instead prefer to have rDUINOScope done for them. Otto produces this hardware and sells it as “out of the box” ready GOTO.
