Risks

Switching to surface mount brings with it a lot of unknowns as we have never worked with it before.

Changes

Interpreter:  Adding functions to the language to allow for more interesting example code.

Firmware: Reading neighbor messages are now triggered via IR pulses, causing interrupts (instead of synchronizing on the sending bit). Tiles will now be in sleep-mode most of the time, except for when explicitly communicating with other tiles; the neighboring tiles will send a “wake up” pulse to the tile to wake it up.

Circuit: Switching to battery powered, lowering the voltage of the circuit, and switching to surface mount.

Schedule

We are behind schedule because of problems with our power requirements.  We have addressed those problems this week as explained in our individual reports and will work to get caught up next week.
