DIY Arduino Battery Capacity Tester - V1.0

DIY Arduino Battery Capacity Tester - V1.0

Major corrections and additions made 9/9/2014 See the new and improved 2015 version at http://www.green-trust.org/jmcFor my off-grid Ham Radio and Solar projects, I needed a way to measure volts, amps, watts, amp hours and watt hours. There's a couple of commercial products that can do this, but not with the flexibility I wanted. I designed a Arduino micro-controller based solution that is very extensible. Right now it monitors the above values of attached gear, a...

A variable power supply is one of the most important pieces of equipment to have on the electronics workbench. It's only a matter of time before the voltage or current required in a circuit isn't practical for battery power.Bench-top variable power supplies available today are typically transformer-fed linear voltage regulators which are both simple and inexpensive to manufacture. However these supplies are also large, heavy, and inefficient for most of their output voltage range. Man...

Ever wondered about how simple an User Interface (UI) for your next electronics hack or project be? Indeed, and you should also seen the humble rotary encoder and a Display as UI for 3D printer or other gadgets. In this tutorial we will look at building such a system with a Nokia 5110 display and a rotary encoder KY-040. You may use any other character or graphics displays as well as other encoder models. Instead making the code generic, we will start building an UI for a digital clock. On…
