Still working on pin issue

Looks like we have agreed on how to solve the extra AVR pin issue which means the schematic for rev2 is pretty much finalized and now the task is to place the components on the PCB.

Added output RCA jacks to dexter schematic

So as to make some progress, I tackled one of the things on my TODO list which can be solved independently of the current AVR dilemma: adding RCA audio output jacks to the schematic. I finished this up so now the two main obstacles to a rev2 PCB are settling on how to get the functionality that we could have if we had an extra pin, and also doing the actual PCB layout.

Considering ATMega325P but running into trouble

We are short 1 pin on the ATMega324P so we've been considering the 325P instead which has a lot more pins on it. Unfortunately, this morning I just discovered that the 325P seems to be light on features that the 324P had such as multiple USARTs and multiple external interrupts. So now I'm stuck. Maybe we can consider the surface mount version of the 324P which probably has a few more pins on it.

Back from vacation

I'm back from my vacation and am ready to resume work on Dexter.

I wanted to get my presentations from CAX online before I did anything else because I knew if I didn't do it soon, I would never get around to doing it. Now that that's out of the way, I can resume the fun stuff.

Going out of town

I am going out of town for the weekend. I will have limited access to the internet. I will try to do some work on rev2 on my laptop while I am gone (that's what vacations are for, right? working on cool projects!)

CAX Presentation part 3 of 3

Here is the final part of the CAX video. It is mostly questions & answers.

Part 3 coming soon...

I will have part 3 with subtitles posted next.

Possibly some time today... :)

After I get the CAX presentations posted then I can get back to the rev 2 PCB design.
