The Daily Duino

One of the nicest things about most micro controllers is their low power requirements, thus giving one a large range of possibilities powered by 5 volts.  Since this is such a low power consumption, we are given to a wide range of methods to power and/or charge our power supply. The first and perhaps easiest [...]

The color selector is 3 linear pots that control the rgb values of a square in a window. The window also displays the rgb values. Kinda simple to make, I reused a lot of code from the etch-a-sketch sketch. I am working on my processing book, so my projects should get better. The dot in [...]

Several of my favorite Arduino/Freeduino stores have sent us in some giveaways for the con.  We are not sure how we are going to be giving things out, as most are kits, I think we will be giving them out during our talk and during the tutorials going on during the day.  Maybe get a [...]

I saw this floating around the web and wanted to share with all.  Its free printable graph paper that allows you to scan your drawing without picking up the graph lines with your scanner. http://konigi.com/tools/graph-paper I also archived it on our site, http://dailyduino.com/graphpaper/ way to go konigi!

Arduino Floating Ball from droops on Vimeo. Arduino Etch-a-Sketch from droops on Vimeo. I had seen some similar things on the internet, but I wanted to make my own.  I took 3 pots hooked up to analog inputs on my Arduino and then sent a serial connection that looked like this: X56 Y378 Z5 X68 [...]

Morgellon and I will be talking about “The Extraordinary Journey from Fundamental Electronics to Fabulous Enchanted Systems with Arduino’s and Magical Potions” at PN 12 http://phreaknic.info/pn12/ droops and Morgellon will take you from basic electronics to building embedded systems. Learn how to build a standalone RFID tag reader with a fancy LCD display or your [...]

First off, Morgellon went to school for this kind of stuff and has a fancy degree in electronics wizardry or something like that.  I on the other hand, am reading books on processing, embedded electronics, microcontrolers and basic electronics. Everyone says use Eagle, here is a tutorial, learn Eagle… I have been working on that [...]

Many of ya’ll have seen this really cool hack of an oscilloscope built with an Arduino and Processing. http://accrochages.drone.ws/en/node/90 I have been playing with it a bit and have added some functionality to it. It now supports up to 3 inputs, 6 if i add a bit of code, has a second counter since the [...]

After watching Citizen Engineer, I wanted to play with a slotted optical sensor, well that and a payphone, a sim card reader, a little vice and other cool electronics things. So I ordered a few from All Electronics. As usual, I had no idea how these things work, so I started plugging in wires and [...]
