We happened to find an old Zenith radio at a yard sale for not much money and decided to upgrade it, calling it Zen Radio. We removed most of the insides but kept the speaker and all the controls. Then we got to work on giving it an upgrade to play MP3 files. (more…)

Stand Alone Arduino

  Stand Alone ArduinoMaking a stand alone Arduino is actually not all that hard. Five years ago I bought enough parts to make 10 of them. The reason for choosing 10 is that at most parts suppliers you get a discount for buying 10 or more of an item. We followed this tutorial to make them and spent about $13 - $14 on each one, which was cheaper than buying an Arduino Uno at the time. Now you can get an official Arduino Uno for $24.95 , so let's see if making your own is still cheaper. (more…)

Simple Voltmeter

Over at Instructables, user braulio777, show you how to make a voltmeter with an Arduino. Also using a 10k resistor, 100k resistor and OLED display.  We like the simplicity of this setup. http://www.instructables.com/id/Arduino-OLED-Voltmeter/

Realt Time Clock

Here is a fun project we made a while back that involved soldering, coding and have a case 3D printed. DIY ClockWanting a clock for my work area, I made one using an Arduino Deumilanove, Chronodot RTC, or real time clock, and a 7 segment display. I had the box custom 3d printed on Makexyz.com.The lid slides off, out the back. (more…)
