I received the Main Clock controller board on 04 Aug 12. To my horror, the board was the old design that I had submitted to the vendor for getting an estimate. I immediately contacted the vendor. He has accepted his mistake and has said that he will reship the new boards. The second batch of boards arrived on 05 Aug 12, and as expected they too were from the old design. However, there was not much of difference between the old LED matrix design and the new one, so I have accepted one of the boards and have shipped the old boards back to the vendor. The boards should be with me by end of next week.
14 Aug 12 : Got the PCB’s today evening. Quality not that good compared to the previous lot. However still much better than a home made PCB.
15 Aug 12 : Soldered and tested all the boards. To my relief, all of them are working sat. I was able to upload the Arduino boot-loader onto my board. I will share the process shortly. Below is a test video of a four 4×4 led panels arranged to form a a 8×8 panel and displaying 5×7 pixel font ASCII characters.
18Aug 12: Boards now have been mounted on a perspex sheet and ready for testing. Arduino is connected in a piggyback mode for programming and debug purpose.
19 Aug 12: Testing code to verify single character scrolling. Code is available here
20 Aug 12: Just printed the fasica on piece of paper to test the code and the light baffle. Here is a working demo. This is not the final piece.. but is more or less like it.
23Aug12: Received the laser cut light baffles. My idea worked better than what I expected. Does what its supposed to do.
24 Aug 12: This is the
Version 1 Version 1.1 of the code. Download IshansWordClockV1.1 code
25 Aug 12: Finalized the code and made the whole prototype as it would look in a final product. Everything looks good except the fascia. Waiting for my vinyl stickers, should be in my hand by Tuesday. Following are some pictures of the pre-boxing up build
