 This DIY Vacuum Fluorescent Display Driver uses a 555 Timer to drive it. Most of us have used a 7 segment display before and they are very simply to power since they are just LEDs and it is very simply to power LEDs. Kerry Wong had a VFD but no driver, he built one using a 555 timer, a hand wound transformer and a hand full of other
 There are a ton of sensors available for the Arduino. These days indoor air quality is on the mind of many people wanting to improve the quality of life and health. What could be better than a home made system that uses and Arduino and a bunch of sensors to monitor everything around you. This project also interfaces with Thing Speak to allow the data to be viewed
Want to make a tiny scope? This Arduino LCD Oscilloscope project would be a fun weekend project. Â “I used an Arduino Fio board that I picked up from SparkFun.com (available at Amazon.com) and a small SPI graphical LCD board that I picked up for a few bucks at dx.com (SKU 153821, also apparently available at Amazon.com).”
  When I think of a 7 Segment Display I think of a small display plugged into my breadboard with some wires plugged into it. This clock uses 7 segment displays that are nothing like that!. In fact these 7 segment displays are all mechanical and are actuated using tiny servo motors. Just think of the noise it would make if the time wasn’t set and it was flashing 12:00.
This project demonstrates how to use a voltage divider to read in analog voltages with an Arduino. Since we are using a voltage divider the voltage that the chip sees is within it’s range even though in this case the voltage measured can be up to 50 volts. The Arduino then calculates the actual 4 analog volages and outputs them on an LCD. Have a look at the code
 The prize this week is an Arduino Mini Clone. This contest will run for one week (June 8 – 14, 2013). Ending time is based on central standard time. To enter, identify the item above and what it can be used for. Please note the image above is a side view of the thing. Please do not give the answer in the comments. Send an email to contest
I have never tried this technique so you might want to give it a try on a record you don’t like much before doing it on a record you would hate to destroy. Unlike the Green Marker Trick for improving the sound of CDs I think this technique would work quite well. All you need to do is goop some wood glue onto the record, wait for it to
