Power Usage Monitor
Power
Power Usage Monitor
Difficulty

In this project we built a current meter using the AC712 current sensor, instead of just displaying or reporting current measurements we made the project a little more interesting by calculating power consumption (which is just POWER = CURRENT x VOLTAGE), and reporting the power consumption via email.

Low Battery Alarm
Power
Low Battery Alarm
Difficulty

Simple alerts with the low battery alarm

Power
LoRa Remote Relay
Difficulty

We are very excited to get the chance to play with our new LoRa Shields, and test just how far we could get a signal using LoRa technology.

Power and Arduino
Power
Power and Arduino
Difficulty

There's a heap of modules and shields for controlling power with Arduino, for example the XC4488 MOS Driver, XC4472 Motor Driver Shield or even the XC4418, XC4419 or XC4440 relay modules.

Current Shunts
Power
Camping Battery Meter
Difficulty

This is more of an electronics lesson than anything else, We go over the fundamental electronics for building a complete circuit idea, discussing Ohm's law, Kirchhoff's law, analog and digital values, and the difference between website and embedded-C code.

Power
Hand Gesture Power Socket
Difficulty

Wax-on Wax-off lighting, just like karate kid! Use this gesture controlled powerpoint kit as a fun way to turn on power sockets around your house.

Benchtop Power Supply
Power
Benchtop Power Supply
Difficulty

What better way to get back in to work with your own personal benchtop power supply.

Power
WiFi Mains Switch
Difficulty

Control one or multiple power points with our IoT WiFi Power Switch Project

Power
DIY power leads with Anderson High Current Connectors
Difficulty

In this project, we explain Anderson 50A High Current connectors and how to use them to make different leads common in camping, caravaning and four wheel driving.

Telescope Dew Heater
Power
Telescope Dew Heater
Difficulty

This project brings together a few Duinotech Modules and some other parts to create a versatile tool.

Power
High Efficiency Power Supply
Difficulty

Learn the basics of electronics in making this high efficiency 5V power supply.

Power
Wi-Fi Relay Controller
Difficulty

Use relays effortlessly with this simple two-part setup! Simply connect any device you want to test or activate to the relay module; then use the in-built phone app to control them whenever you want.

Power
Solar MPPT Charge Controller
Difficulty

Wondered what goes into Solar charge controllers? And what makes MPPT better than any of the others? Find out yourself, by making this Solar MPPT Charge Controller project. Uses a simple Arduino Nano to control and regulate the flow of power from the panel to the battery, and has a output relay to automatically turn off when the Battery gets too low. A great project for DIY amatures and solar aficionados.

Power
Bluetooth Power Point
Difficulty

Control a collection of power points with your phone app.
