Stuffing for Christmas

So, yesterday's post showed the bare PCB.  Today we have the stuffed board ready for bring-up:
During bring-up I'll be adding each IC in turn, making sure it is doing what it should be doing.  The last one with be the CPLD - you can see the in-circuit programming header top-left of the board (a couple of the pins are also used to set the board address).

I've also checked the board fits into the PC. The next version of the PCB will be gold-plated.

New project just in time for Christmas

I've started work on the next project.  Well, "started" in this case means getting the first prototype PCB back from the fab:
Took a while to get everything to fit, and the release version will be a little bit simpler.  As to what it does....I'm sure there are some folks out there who will be able to work out what this is for!
