How to build your own impossible Eiffel tower - a fully 3D printed tensegrity structure in gift-card format.

How to print and assembly the Arduino based Bluetooth (BLE) Android controlled RC car BlueCArd. In this tutorial, I'll show You how to print and assemble the fully 3D printed Arduino based and through Bluetooth Low Energy (BLE) with Android device, controlled RC car BlueCArd. At the end of this tutorial, You should be able to build your own BlueCArd. 3D printing the parts I designed all parts to be as easy as possible to print. I used these settings for all parts: 20% infill

Fully 3D printable four bearings Spool Holder for 3D printer enclosure. This spool holder is optimized for easy spool change (no screwing / unscrewing needed). First things first Download the Spool Holder from Thingiverse: https://www.thingiverse.com/thing:4458183 How to print: All parts can be printed without support, brim or raft. Print with 0.4mm nozzle. 1x Base - print with 0.3 layer height and 10% to 20% infill 2x Shafts - print with 0.3 layer height and 10% to 20% infil

How to connect a servo motor to an Arduino Nano microcontroller and how to control it from an Android device using Bluetooth Low Energy (BLE). This tutorial is part of the BlueCArd tutorials series with the ultimate to build the BlueCArd Arduino based RC car controlled from Android phone through Bluetooth. In this tutorial, I'll explain what is a servo motor and how to connect it to an Arduino microcontroller. I will also show you how to control it remotely from an Android de

How to level the bed of a Prusa i3 MK3S 3D printer using 3D printed TPU rings, so You can get a perfect first layer. No matter how much I tunned the first layer offset I wasn't able to get a good first level on all places over the hot bed. Eventually, I installed the Bed Visualizer OctoPrint plugin. After I ran the bed leveling and collected the data I saw this graphic: On a side note. To install the Bed Visualizer on a Raspberry Pi Zero you need first to install the numpi li

How to connect and control a DC Motor to an Arduino Nano using an H-Bridge and how to send commands from Android to the Arduino Nano microcontroller to control the DC Motor. This tutorial is part of the BlueCArd tutorials series with the ultimate to build the BlueCArd Arduino based RC car controlled from Android phone through Bluetooth. In this tutorial, I'll explain how an H-Bridge works and how to use it to control a DC motor. Then I'll show You how to extend the Android Ap

How to connect to and control an Arduino Nano with an AT-09 / HM-10 Bluetooth Low Energy (BLE) module from an Android device. This tutorial is part of the BlueCArd tutorials series with the ultimate to build the BlueCArd Arduino based RC car controlled from Android phone through Bluetooth. In the last tutorial I showed you how to connect the Bluetooth module to the Arduino microcontroller and how to send data between the Arduino Nano and the BLE module. In this tutorial we wi
