Introduction I’ve been fascinated with joule thief circuits since I made my first one. It’s amazing what all you can power from a single AA or AAA battery. The only problem is you can’t do much beyond light up an LED because the current isn’t “always on”. With a couple of extra components, you can […]

ATtiny85 for Simple Projects: Arduino Basics
Bare bones: The ATtiny85 on its Own The ATtiny is a small, inexpensive chip that can replace the Arduino in a project you have prototyped. This helps make the project smaller and more permanent, as well as freeing up the Arduino for more fun! The chip comes in a few different types – ones with […]
OH HAI! on Windows 10 IoT Core
Oh, Hai Hai (‘hi’) is an integration point for several stand alone smart home technologies. Hai runs on the Raspberry Pi and can be adapted to optimize electricity consumption (lighting/HVAC) and water usage (irrigation/rain collection) in a number of ways. Hai was originally envisioned for any Pi running Raspbian OS, but is also being ported […]
