Very cool , this definitely looks like a project I would try on an AVR. However, the included schematic would need to be modified for an AVR, since this one uses a PIC>

Update: Razor Concepts and I are in the midst of converting this project to using an AVR. We are almost done - just need to fix up the PCB layout of it.

Current board file

Credit-card sized with mega168

PCBs are in, time to solder.

it looks ace so far

i want one!!!

can you draw us a schematic for that,
and give us tips on making it

airman00 · « **Reply #6 on:** January 28, 2009, 01:31:26 PM »

I'm probably gonna make a kit out of this in the next month or so.

tigy888 · « **Reply #7 on:** January 28, 2009, 02:17:34 PM »

cool!

tigy888 · « **Reply #8 on:** January 28, 2009, 02:19:10 PM »

can you create a tutorial

Razor Concepts · « **Reply #9 on:** January 29, 2009, 09:16:21 PM »

Not sure what kind of tutorial you would need, besides how to solder 2mm long leds

(it isn't fun)

Anyways I managed to get one row of LEDs soldered, so I tested out some night rider code!!!!
Too bad the new series got rid of the firebird, the new mustang isn't good enough. Oh well.

Scrolling text works! Waiting for the SMD pushbuttons to come in the mail, after those are installed it will be finished.

have you got a schematic that you could post please?

Razor Concepts · « **Reply #12 on:** February 07, 2009, 02:25:05 PM »

Sure, not much to see though.

Very good, very clean, I like it. Do you have the source code?

frodo · « **Reply #14 on:** February 07, 2009, 02:46:12 PM »

thanks, very good schematic. same as MaltiK

Razor Concepts · « **Reply #15 on:** February 07, 2009, 02:47:32 PM »

Not yet, will post as soon as I'm finished.
Also this project uses two languages - Java and C. I use a Java program to convert text to a matrix of 0s and 1s. You copy the matrix into the C program which is what the microcontroller uses.

frodo · « **Reply #16 on:** February 07, 2009, 02:51:40 PM »

i thought java was the computer script that enable you to play games.

Razor Concepts · « **Reply #17 on:** February 07, 2009, 03:27:03 PM »

Java is used to program games but it works well, and is pretty much designed as just a general purpose programming language.

RazorConcepts just finished testing out our boards. It looks awesome. Expect an LED dot matrix kit from Narobo.com later this year!

WOW!! could you put a video of one with the casing on please? I WANT ONE I WANT ONE

izua · « **Reply #20 on:** February 08, 2009, 11:54:48 AM »

Please post some measurements

Razor Concepts · « **Reply #21 on:** February 08, 2009, 12:21:36 PM »

I haven't made a casing yet.

Board is 3.30 by 2.10 inches
84mm x 58mm
