Swarm vs. Iridium For Satellite IoT

From nootropicdesign.com 3 weeks ago in Blogs

Using Satellite for IoT If you are involved in building Internet of Things solutions for industry, you are probably familiar with radio technologies that connect IoT sensors to the Internet: WiFi, cellular, LoRa, etc. What about satellite connectivity? Wifi or...

Laser Show Motor Controller

From nootropicdesign.com 2 years ago in Blogs

Here’s a fun idea I had while quarantined during the 2020 pandemic. I have a bunch of these cheap laser modules that can easily be driven from an Arduino with 5V, and they only draw 20mA of current. I also...

Iridium Satellite Signal Monitoring

From nootropicdesign.com 3 years ago in Blogs

Project source code at GitHub: iridium-signal-strength-monitor In a previous article, I wrote all about Iridium satellite communication for IoT projects using an Iridium modem and simple Arduino technology. However, when trying to send a message to a satellite constellation, you...

Automated Weather Satellite Ground Station

From nootropicdesign.com 3 years ago in Blogs

Project source code at GitHub: wx-ground-station This project will show you how to create a fully automated ground station that will receive and decode NOAA weather satellite images and upload them to your own website served from an Amazon AWS...

Iridium Satellite Communication with Arduino

From nootropicdesign.com 3 years ago in Blogs

When deploying a microcontroller-based IoT solution or just doing experiments gathering data in the field, you often need a way to get the data back to your home base or to the cloud somehow. You’ve probably used WiFi, maybe dabbled...

Arduino Audio Hacker Realtime Voice Changer

From nootropicdesign.com 3 years ago in Blogs

Here’s another fun but simple project using the Audio Hacker shield for Arduino. This is a realtime voice changer, which is an improvement upon the original voice changer example I provided with the Audio Hacker library. This project uses a...

Arduino Audio Hacker Realtime Reverser

From nootropicdesign.com 3 years ago in Blogs

Here’s a fun project using the Audio Hacker shield for Arduino – a realtime audio reverser! This program records the audio input to the Audio Hacker’s memory but plays it back in reverse. The “play head” jumps ahead a bit,...

Arduino Shield for CAT M1 and NB-IoT Modems

From nootropicdesign.com 3 years ago in Blogs

LTE CAT M1 (sometimes called LTE-M) and NB-IoT are both exciting new cellular technologies targeting IoT applications. While there are many modems being built with this new technology, there are not many choices for hobbyists. There are a few Arduino...

Building an IVR with Twilio and Node-RED

From nootropicdesign.com 4 years ago in Blogs

Project source code at GitHub: node-red-contrib-twilio-ivr Twilio is fast becoming an important part of Internet’s communication infrastructure. What is Twilio? Twilio is a developer platform that allows you to add capabilities like voice, video, and messaging to your applications. This...

LoRaWAN Networking Part 2: Using End Devices

From nootropicdesign.com 4 years ago in Blogs

In part 1 of this series I showed how to set up a simple LoRaWAN gateway, and in a previous article described a simple but powerful LoRaWAN-capable end device that I designed. Now I’ll show how these devices can be...

LoRaWAN Networking Part 1: The Gateway

From nootropicdesign.com 4 years ago in Blogs

I have been playing with LoRa modules a lot recently (see projects LoRa Weather Station and LoRa Mesh Networking) and even designed my own LoRa development boards. LoRa is an easy way to achieve low-power, long range radio communication with...

SAMD21 LoRa Development Board with GPS

From nootropicdesign.com 4 years ago in Blogs

I’ve been doing some LoRa projects lately in order to learn as much as I can about this exciting new radio technology (see this LoRa mesh networking project and this LoRa weather station). ATmega328-based Moteino modules work great for a...

LoRa Mesh Networking with Simple Arduino-Based Modules

From nootropicdesign.com 4 years ago in Blogs

In this project, I will show you how I built a mesh network of 4 Arduino-Based LoRa modules and devised a way to visualize the network’s behavior in realtime. Using a realtime visualization we can see how the network forms...

Wi-Fi Camera Trap

From nootropicdesign.com 5 years ago in Blogs

Project source code at GitHub: wifi-camera-trap We have lots of small wildlife around our house (mostly rabbits this year) and since I have a small camera module and a cheap PIR (passive infrared) motion sensor, I thought it would be...

Solar-Powered LoRa Weather Station

From nootropicdesign.com 5 years ago in Blogs

Project source code at GitHub: lora-weather-station In this project I show how I built a remote, solar-powered weather station that transmits temperature and humidity readings over LoRa, and a base station that publishes the data to the Internet with MQTT...

Introducing the IoT Experimenter ESP8266 Development Board

From nootropicdesign.com 5 years ago in Blogs

Like many other hardware hackers, I fell in love with the ESP8266 Wi-Fi microcontroller as soon as I started using it. It is fast, has plenty of memory, has Wi-Fi networking, and can be programmed in a number of ways....

Wi-Fi IoT Electrical Outlet: Turning on a Coffee Maker Remotely

From nootropicdesign.com 5 years ago in Blogs

Project source code at GitHub: iot-wifi-outlet They say necessity is the mother of invention, and there’s no question that the need to turn on my coffee maker while still in bed is a necessity. I don’t want to wait for...

Individually Addressable Incandescent Lamps

From nootropicdesign.com 6 years ago in Blogs

Everyone playing with electronics these days knows about LED strips made of dozens or hundreds of individually addressable RGB LEDs. I love them and make great use of them in the nootropic design Lumazoid music visualizer. But what about incandescent...

Frequency Filtering with the Audio Hacker Shield

From nootropicdesign.com 7 years ago in Blogs

The Audio Hacker shield for Arduino lets you do some cool things with digital signal processing. This new project shows how a fairly simple Arduino sketch can implement a low-pass filter, high-pass filter and band-pass filter. A low-pass filter allows...

Using a Video Experimenter as MIDI Controller

From nootropicdesign.com 7 years ago in Blogs

This simple project shows how a video signal captured by a Video Experimenter Shield can be used to send MIDI messages to a synthesizer. A small camera module is connected to the input of the Video Experimenter (the red wire...

Digit Shield Used in Concrete 3D Printer

From nootropicdesign.com 7 years ago in Blogs

Wow, this is the craziest 3D printing I’ve ever seen. The material is concrete! Andrey has been working very hard for years to developed a 3D printer than can literally print houses. Here is the castle he printed. For more...
