Well… so I will explain briefly how I made this part… Each square has 8 red hight brightness leds inside no oriented upwards so the light difusses better. It makes 200 total leds, it’s a bit boring to solder so many leds… The control of these leds ia made with a PIC 16F876A Microcontroller. The control software is in C and I made a software in order to design the sequences. The sequences are changed via RS232 communication when I play music on Winamp I programmed a PlugIn that synchs the table with the music bpm’s… Maybe all the software stuff was one of the easiests and fastest to develope as I have long experience with the subject.

So… the PIC receives the signal via RS232 (I will make this communication via Zigbee when I get some Xbee modules) and transmits them thorugh I2C to PCF8574 that make use of the ULN28003 in order to get enough current to feed the leds…

So here are some pictures of the soldering process (It was quiet boring and the results are not very well looking, but none will see the soldered board):

of How many mcd are the leds that you use?

Hi,

Nice job.

Is possible to share the schema and Hex ( or MiKroC source file)

My best regards,

Is there any chance that you could put up a link or something of the scematics you used to build your boards both for the control side and the LED side?

Hi - nice table! I'm looking to build one from your instructions - do you have the winamp plugin and circuit diagrams available. Any help very much appreciated.

Would you be willing to make the control software and the winamp plug-in available for download when you upload the circuit diagram?

I hope i post my schematics this weekend when I have a little time...

Sounds great! Also, would you mind detailing what hardware solution you used to program the chip for those of us looking around at purchasing our first programmer.

Do you have a circuit diagram ?

Not at this time, I'll try to scan one when I have a bit of time...
