Arduino LCD Oscilloscope

  Want to make a tiny scope? This Arduino LCD Oscilloscope project would be a fun weekend project.  “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).”

Manual 7 Segment Display

   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.

Read Analog Voltages with an Arduino and display them on an LCD

  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

Name the Thing Contest – 231

    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

Clean a Dirty Record using Wood Glue

  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

Space Station Lamp

    If you want to be notified whenever the Space Station is flying overhead this Space Station Lamp project by Nathan from Mechanical Integrator is sure to help out. A number of LEDs edge light a piece of frosted plexiglass and a Teensy microcontroller does the work. Some Python code is used to check to see when the Space Station is over head. If you are interested in making

Jeremy Blum Remote Controlled Graduation Cap

    Congrats to Jeremy Blum for graduating from Cornell University! He made a cool Remote Controlled Graduation Cap that he controls using a custom built wrist control box. The cap has an RGB LED in it and is capable of not only grabbing user submitted color suggestions but also a variety of pre-programmed ones. If you would like to see how it works Jeremy has made it open source
