This instructable goes through how to design and print a variety of 3D models using a system called the ‘UCube’. Note: I would love to eventually publish detailed instructions on how to make your own UCube, but since the design is still changing and improving, this post will gloss over a lot of those details

Like me, you may have a few old Arduino boards or ATmega8 chips (in the boards) laying around from when you were first playing with Arduino. Those chips can still be really useful as the heart of a tiny “Minimal Arduino” setup. A normal Arduino board contains support components that make it easy to use.

The 74HC595 is an easy and inexpensive (at about 60 cents apiece) way to increase the number of digital out pins on your Arduino. In this tutorial I’ll show you how to drive up to 16 LEDs with one 74HC595 using a technique called multiplexing. In the end, all 16 LEDs will require only three

Sometimes when you’re testing a sensor or debugging a value in an Arduino project, you want to see something other than numbers flying by in the Serial Monitor. However, you want to get the sensor working quickly, and you don’t want to take the time to write code to graph it or display it in

I’m currently helping a couple of engineering students finish a senior project that didn’t get finished last year. Long story… Anyway, it’s a bicycle brake tester being built for Paul Components. The mechanical design is great, but they had trouble with the electronics. Part of those electronics involved writing numbers to a pair of Sparkfun

I got my start in microcontrollers with the Arduino, as many of us outside of electrical engineering did. (And still do!) The ease of programming that little board makes it a great gateway… and like any gateway, sometimes you go through. Most of my projects now don’t use Arduinos directly. For simple microcontroller applications, it’s

One of the most fun and useful projects on instructables is to create your very own solar USB/ iPhone charger. They’re not overly difficult to make, nor are the parts overly expensive or hard to find. For the most part they do a rather good job of charging up small gadgets. Mostly. The big flaw

If you have looked at my 5 LED ATtiny85 POV display, we programmed the ATtiny with the Arduino. (If you haven’t seen it, click here) We will be doing the same thing for this LED Dice project. The total parts cost for this project is about $5-$10. (Not including the Arduino board and the tools.)

Ever wanted an LED tree? Well now you can have your LED tree and eat it too (no, wait, you probably shouldn’t).. Step 1: Gather the parts You will need: 1x ATtiny85 10x male header pins Solid core wire, 2 colors A bunch of LEDs 1x Arduino Uno to program the ATtiny Step 2: Program
