DIY Universal TV Sleep Timer

  Have you ever wished you had a remote control that could be set to turn off your hotel TV after a predetermined amount of time? This DIY Universal TV Sleep Timer is sure to keep you sane next time you are in a hotel and come across one of those low budget remotes they always have. Nice thing about the code is that you can program your own Arduino

DIY Motorized Standing Desk

    If you are tied to a desk for much of the day a standing desk might allow you to feel better after a long day of sitting. Standing desks are still very expensive and not that popular. Loren has built a kick ass standing desk from scratch. It can be raided and lowered with ease since there are 4 linear actuators that can easily power the desk up

PiMiner Bitcoin Mining System

  Are you feeling the hype of Bitcoin yet? Instead of having a full blown computer mining your fortune in Bit Coins why not make solution that can fit in your pocket? The PiMiner Bitcoin Mining System uses USB miners that simply plug into USB ports on the Raspberry Pi. “Building this project will allow you to use a Raspberry Pi as a ‘headless’ controller and status monitor for your

UV LED Drawing Parallax Robot

  Check out the cool UV LED Drawing Parallax Robot that Gareth built from a S2 scribbler robot. “I have replaced the pen slot with a bar of downward pointing UltraViolet LEDs one placed central to the hole and the others fanning out….. This arrangement means that i can send the Propellers internal character-set (no costly data tables) to the UV array and plot to a Phosphorescent screen.”

DIY Vacuum Fluorescent Display Driver using a 555 Timer

    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

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).”

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
