About this project Helium exists to help developers build low power, secure, connected devices. In this project, we’ll walk through using the Helium Atom Prototyping module with an Arduino Zero and Adafruit Ultimate GPS Breakout to seamless send data to Azure IoT Hub and then on to a Power BI report to visualize the data. […]

Motivation So I’ve just spent an “all nighter” working on this new IoT device that’s going to change the world. The sun comes up, and I’m off to demo the device and pitch to my friends for some seed capital and soul crushing criticism. I get to their house, turn the device on, it won’t

The ESP8266 has a few common issues, specially when you are trying to flash a new firmware or uploading scripts. This is a companion guide to the Home Automation using ESP8266 and Password Protected Web Server eBooks. Here’s a compilation with some of the most common problems with the ESP8266 and how to fix them. ESP8266 Troubleshooting – NodeMCU Flasher Where do I download
A friend has approached me regarding his solar project. He wants to install a solar panel together with a battery and an inverter in order to have power at his allotment garden. He had looked at a hobbyist project where an arduino was used to build a MPPT (maximum point of power tracking) charge controller.
Purpose and concept The “LayoutLights” concept was born when I wanted to remotely control (using a PC with a USB port) the lights on the train layout. I wanted to be able to switch on and off all the lights in buildings, structures and on platforms, streets and other locations.The basic principle is simple :
I just wanted a simle DCC central wich I can use to test new DCC locomotives n ad potentially with a “program” mode so it can “break in” new locomotives for me by running them for specific periods of time in both directions. The result is an Arduino based DCC central. It is based on

What is this ? This project is a “real size” speedometer for miniature trains, cars and anything you wish to measure. It can calculate the speed of the object between 2 measuring points along the track (or road) by counting milliseconds between passages at the start and end gates. If you enter the distance between
Most projects include at least one LED. Before soldering the LED, how can you determine if the color and brightness meets your needs? After that, how do you calculate the correct value resistor? Many years ago, I built a handy compact LED testing tool based on the LM317L adjustable current regulator. (You’ll definitely want to
This is an electronic input switcher for amateur DJ’s who are running short on inputs on the audio mixer. It allows you to connect 2 inputs to channel 1 and 2 each, and 3 inputs to channel 3. Each input channel has a toggle switch and 2 or 3 LEDs indicating the active input. The actual
This project allows you to build you own CCTV switchbox, that you can use to connect up to 6 cameras to a single screen. The camera signal (CVBS over CInch or any other) is switched to the output using SPDT or even SPST relays.How it works ? – by default the controller will cycle through all 6
