LED Table

at 11:19 pm. Filed under DIY Hacks, Electronic Hacks


If you are wanting to jazz up your simple coffee table why not make an LED Table? We have seen other LED tables before but this one is made up from very simple parts and might be a great intro project to electronics. Nice thing about this design is since there are no controllers used there are no parts that need to be programmed, this means that once you solder the bits together and flip the switch you should be in business.


  • 240 Leds
  • 300 12v 470 ohm resistors
  • 60 22k resistors
  • 60 3 leg photo transistors
  • 120 transistors (2N 3904 -J05)
  • Spool of bailing wire
  • Small spool of thin non stranded copper wire
  • Ethernet cable or equivalent
  • Simple SPST switch
  • 12v DC bulb and holder
  • Converted computer power supply
  • Electronics grade solder
  • Hot glue
  • Electrical tape or shrink tubing
  • Thins sheets of semi flexible clear plastic, I used the replaceable plastic face inserts from a face guard I no longer had the base for, “waste not want not”
  • black silicone tubing, similar to kind used for fishing gear, or sling-shot”

    i also build a RGB table – maybe someone is interested in it: here’s a video http://www.youtube.com/watch?v=-ZEpcBto1l4

    It consists of 7×10 RGB Pixels, each build from 6 RGB LEDs and controlled via Artnet/Ethernet.
