Javalin Clock Project

Hello All;
I am new to this board. I have been working on the Javalin stamp. They say you need a project to learn a language. I am finding that the Javalin is an astounding development set. Super well thought out in advance. The carrier board is a work of art. I had several DS1302 clock and crystal sets that had never been used. Every time I read the chip docs I walk away thinking this is to hard to figure out. I downloaded the DS1302 RTC real time clock class from the Parallax Lib and WHAM it ran the first time. I figured if one was that easy to get running why not try 5 clocks and look at drift and build a self correcting chronometer :-) I did. It works :-) I am now writing a PC application to hook the Javalin to www.time.gov for self correcting lab time standard. I am learning Java very quickley. The board was point to point soldered with no daisy chaining. I also had some super caps and I wired them in also. What a fun way to learn Java :-) I am also finding that with out a garbage collector you have to be real careful with strings.

Nice work on the Javelin RTC project. I hope you never tear these projects apart after you make them. You've put a lot of effort into the PCB perf-board part as well as the code. With so many of my past projects I scavenge the parts for the next version, sometimes making me wish I had the original. At least the Stamp and LCDs can be easily re-used.
