Low-voltage DC energy logging: sample voltage and current, correct offset, integrate over time, and separate uncertainty from billing-grade metering.

If you’ve ever wanted to bring a piece of paper to life, now is your chance. This instructable will take you through all the necessary steps to create an amazing interactive flyer or artwork. This event flyer is no ordinary piece of print. It is printed using Bare Conductive ink. This means that when it is brought […]

If your school, or kids school, or other location relies on a central master clock that is broken, you may have a use for this device. New master clocks are available of course, but school budgets are under extreme pressures, and it really is a satisfying project if you have the necessary skills. This master […]

The Rainbowduino is a variant of the Arduino and among other things is capable of driving an 8×8 RGB LED matrix. I had just finished a backyard re-model and was in need of an entrance sign. Step 1: Carving and Painting the Sign I had recently acquired a CarveWright CNC wood carving machine. It’s a […]

After working with the arduino and not knowing what the heck I’m doing I made Another simple traffic light. I looked around the web to find one that looks about normal and came across none. They seemed too fast. So, I found and modded some code to make this work. The coding is pretty simple. […]

This Lazy Old Geek is also an Arduino Geek. If you are an Arduino Geek, one of the common microcontrollers used by Arduinos is the Atmega328 chip. In order to use Arduino software, the Atmega must have bootloader software on it. Okay, so I bought some blank Atmega328-PU chips from Mouser.com. TIP: If you want […]

There is a lot of interest these days among hobbyists in controlling brushless DC (BLDC) motors, which have improved performance and better energy efficiency over traditional DC motors, but are more difficult to use. Many off-the-shelf products exist for this purpose. For example, there are lots of small BLDCs controllers for RC airplanes that work […]

This video is from a meeting of the Kids and Technology Meetup group in Washington DC. The youth who show up to these free meetings are eager to learn advanced uses of computers. The presenters were John Dukovich and Hugo Estrada.
