This is my 1w high powerled review







Not sure what to do with that huge wad of cash lying in your bedroom? You could always splurge it on this Ingo Maurer inspired LED table, and considering that it costs a good $23,175, it should do a fairly good job of reducing your pile of cash. The table sports a laminated safety glass on the top, not to mention 278 white LEDs which can emit light both ways. This LED table is powered by 48 volts DC, so you’ll need to keep it plugged in to stay juiced, and you’ll be able to use the external ballast for dimming. You have to admit, having dinner on a $23k LED table would certainly be an interesting experience, though you’d probably get bored of it real fast.

An ever-changing LED display makes for an interesting show. An LED table powered by tweets makes the light show that much more exciting. This Twitter-enabled device builds on a previous project which had uses 81 RGB LED modules in a 9×9 grid arranged atop an IKEA coffee table.



The “Live Twitter Table” extends the multi-colored LED display by adding a Bluetooth Arduino Shield which wirelessly connects to a nearby MacBook Pro. The table is controlled by tweets broadcast with the #ledtable hashtag and formatted with pixel coordinates for the LED matrix.  A Twitter interface code parses the incoming Twitter posts and transmits it via Bluetooth to the Arduino microcontroller. A continuous stream of Tweets sets up the changing display on the LED table.



Macetech details the entire project from the stage of putting together an IKEA coffee table with LED grid including the source code. For your own LED project, you can try hooking up several wireless devices to a central computer and have them display your own LED designs.
