So, not much visible progress has been made over the last couple of months...
The laser cut case from the last video fit pretty well, as you can see them here:
I would like to tighten up the holes a little so that the board doesn't rattle around when the PCB doesn't have feet attached, but it's still a pretty good second effort. Sadly, it looks like I won't be making any more cases for a while - fizzpop moved to their own building, so no longer has access to the laser cutter I used before. There are plans to buy one in the near future, but that'll be a few months off. And besides, I seem to be too busy doing other things to actually make it along anyway!
I've been (silently) working on the FDC emulation (which I decided to do on the Atmega side) - a first version works, but it's a bit buggy. It manages to load a few demos, but it's nowhere near stable enough to release publically.
I've also been trying to get the DVI transmitter chip to work. It looks like I forgot a couple of connections to the chip, although often fixing them up I still can't get the chip to actually transmit any data. It's hard to tell where the problem lies, sadly, so it might still be some time before I get DVI output working...
So today, I decided to investigate how many shades I can coax my 2-bit DACs to produce... I'll give you a clue, it's more than 4! :) There are about 30, although quite a lot of them are difficult to discern, but it looks like there are enough shades to produce the equivalent of a 4-bit DAC. I took some pictures so I can analyse them better:
The other big news is that I've got a new job, starting in 2 weeks. I guess that might mean I get even more busy though...
