Topic: Chumby Power-Outage Reset Dongle
Wheether the chumby should power on after a power-outage is a moot point. It does not.
Aside from rather extensive bickering as to how it should have been, no one has looked into actually modifying the system to do so.
We have heard from bunnie that to make the hardware power on natively requires re-flashing the CryptoProcessor. However, I think that a somple 1-Shot timer that simply plugs in between the Daughterboard and the mainboard, on the chumbilical, is a much easier to implement solution. By having .1" pin headers on one side and a .1" connector on the other sid,e the installation can be made toolless.
It should be possible to produce "Auto Turn-on" dongles very inexpensively.
Schematic was done in a very short peroid of time. I'll sleep on it, look it over tomorrow, and start on a PCB
I'd be interested in hearing how many people would want something like this. I can possibly produce some of them, for parts+labor. Est cost would be $20-40 each, though it's pie-in-the-sky right now.
I'd also appreciate hearing from the chumby staff. If you have any problems with me working-on/possibly-selling something like this on your forums, I'd be happy to go elsewhere, but this seems like it could be useful to a lot of chumby users (plus, I'm not trying to profit, just recoup any possible losses).

Note 2: Altium is freaking out about the harness definitions for some reason, but the netlist builds fine. That explains the red "error" lines.
