Do you miss the games of your childhood? What if you could build your own retro console with a Raspberry Pi and an NES-inspired case? In this very easy tutorial, we’ll teach you how to use a Raspberry PI with the Nespi case and the RetroPie OS to create your […]

itbrainpower.net l-LTE v1.07 4G/LTE CAT 1 shield and l-LTE v 1.07 4G/LTE CAT 4 shield, the smallest 4G/LTE shields available today, have one high-performance GNSS [GPS+GLONASS] engine embedded. By default, the GNSS antenna circuitry is configured for passive antennas [does not have enabled the GNSS antenna power supply circuitry]. Even […]
One of the common questions parents will ask me is how did Beckwith Tech Camp get started? Like most people who suddenly appear, it takes years of practice and work to get to that point. I started literally in my basement, playing with Lego, wiring circuits together, and making matchbox […]
The main purpose of this “how-to” article it is to guide you on how to make a convenient and elegant modular GSM or 3G hardware platform using an Arduino Pro Mini (and related) board, a j-328GSM3GLader Arduino Pro Mini adapter board and c-uGSM / d-u3G / h-nanoGSM modem shields. The purpose of a programmable GSM interface is to be able to communicate with electronics / hardware directly via the cellular network (SIM card required), without the need for a cell phone. You may use such a platform as a mobile IoT interface (access sensor data remotely, or control actuators) or as an SMS / GPRS / DTMF automation platform.
This project will show you how fast you can build your own alarm system capable of supervising one or more magnetic contacts and inform you via SMS of the “burglar event”. You even have the possibility to control (ENABLE/DISABLE) the alarm system remotely, via SMS commands. For SMS communication purposes one of two pin […]
Now that you have either chosen or built a frame, the next step is to choose the right propulsion system. A complete propulsion system includes motors, propellers, ESCs and a battery. Almost all small multi-rotor drones / UAVs are electric, with almost none being gas-powered. For this reason, we will focus on implementing an electric propulsion using brushless DC motors.
This tutorial is intended to complement the Robot Arm Torque Calculator found in the Dynamic Tools section of GoRobotics. The equations used in the calculator to determine the torque required at any given lifting joint (raising the arm vertically) in a robotic arm are presented here. Note that the term “actuator” is […]
