Thanks for the advice. Jon Williams has been a big help to me with designing the 16x16 clock display for the article. He continues to be a leader in the field and offers his help to readers like me. Thanks again!

Thanks for the information about the RabbitCore engine. Seems like there are not many people with good experience in this stuff. I have been focused on Parallax micro-controllers the last 3 years, it's time to break away but not abandon. As far as "we", I am doing some R/D work for a small company w...

We are looking at finding the best and easiest method to interface to large indoor and outdoor signs (single color and RGB video type). SX chips by Parallax may not cut it so we are looking at the ATmega2560 using a BigAVR2 board and also possibly using an Arduino board. I do not have experience wit...

Wow - Nice display! Originally this project was an experimentation at an initial design to display a picture (e.g. smiley face) on a 16x16 LED matrix. However, I then wanted to expand on it to add a clock. However, LED color control circuits took 1 too many I/O pins so I had to move to an SX52 (that...

Thanks Bigglez for your kind words. When I first designed this project I did some point to point soldering on the (4) 8x8 bi-color (tri-color) LED matrixes as well as used Radio Shack perf boards with more point to point soldering the wiring is a bit messy but fully functional. I beleive there was o...

Jan09 - 16x16 Tri-colored LED matrix Real Time Clock

For those interested: The first set of items in the parts list are from Radio Shack as it was not listed. Go here to get the software, documentation, etc: http://forums.parallax.com/forums/default.aspx?f=21&m=189908 Since the SX52 proto board is now obsolete, you may be able to buy a lot of 10 min. ...
