As I mentioned before I am working on an LED-clock with Rik Bootsman. Rik performed a lot of work on the project already while I was busy with the Reporter Bootcamp, ID'11 and the DDW itself. He already made a large chunk of the PCB in Eagle. The only thing I had to do was connecting the datapins and latchpins last Sunday. We worked on the PCB as well as the DCF77 (which was going to receive the time). Unfortunately we could not get the latter working. This is why we came up with a new solution; making a button attached to the Arduino which would reset the time to a default time. This looks like a 'simple' alternative, but we will discuss it with Geert of the e-lab probably before we continue with it.
As Rik finished the PCB on Sunday, Monday was the day to double-check our PCB en look for the options to laserprint it at the university. The laserprinter however, did not agree. It broke last week.. Chet however made a quick phone call to the guys of Easy Laser and they could help us the next day! So on Tuesday it was going to be laserday.It also took us quite some time to export the files properly in illustrator (to and .eps file) with the drill holes in it as well. This would make the drilling of the holes easier, because the drill will 'lead itself into the drillhole' so to speak. Serge Offermans showed us how to do this in a short time, but this way did not include the holes. As a last thing, we made the ISD-chip in Eagle as well, to use a test for the laserprinter.
Next post will be about the printing itself and how we arranged a good place to etch and drill
