Fun fact: None of these images are simulated. Every Mooshimeter on this page is gathering real data in real life. The Mooshimeter was born out of our frustrations as electrical engineers at the limitations of the “standard” digital multimeter. Almost every digital multimeter will only let you use one mode at a time, meaning that […]

We always try to know the physical and electrical data like temperature, pressure, current, ac voltage etc. In this project, I’m going to display these data in the real time as well as I’ill record it to a memory card(SD/microSD/MMC card). Here the project can display four different things; ac voltage, environment temperature, relative humidity

It’s amazing what you can do with just a few components: a load cell, a high gain analog-to-digtal converter and a NodeMCU module. You can for instance measure the water consumption of your dear plants. If you combine the previous mentioned components with a OLED display you can even visualize the current water level in

Sunlight simulation and light therapy light boxes are commonly used as light therapy for treatment of Seasonal Affective Disorder (SAD). My mom has SAD and after seeing her wimpy light box I thought there had to be something better out there, after some research I was really surprised at the underwhelming sunlight simulator light therapy options on

The solution is an embedded module. Swedish company Embedded Artists will help you in tit by their top-class modules with NXP processors. Embedded modules are still more used in many products, where so far a classic microcontroller was sufficient. As requirements for functionality of devices are increasing, including audio/video output, network- and USB connectivity, as

Tunnel diodes are a bit rare these days, but still have uses in special applications including extremely high frequency oscillators, etc. They were commonly used in microwave circuits, oscilloscope trigger circuits, and other applications. This video reviews the basics of tunnel diodes, including the basic properties and simple applications. I refer to these as the

Introduction This is a tutorial on building a Compost Temperature monitoring system. It details how to build a web connected wireless sensor network and shows one possible way it could be constructed. A Medium level of knowledge and skills are required. Basic knowledge of soldering and breadboarding will be very useful. I will assume that
Two triacs switched by zero-crossing optocoupled drivers act as solid state relays on a Dangerous Prototypes standard size PCB. This design is released under Creative Commons Attribution Share-Alike 3.0 License. The schematic is based on a dual triac board created by RobG and posted to the 43oh forum. It suits snubberless triacs in a TO-220 package
