Melodee and I experimented with various woodworking techniques to assemble these enclosures and were able to find a method of creating box joint’s very quickly on a router table.<\/div>\n

I also spent a lot of time this week learning C++ to help Melodee with the firmware.\u00a0 I made a driver library for Melodee to interface with the circuit.\u00a0 Below is the library header.\u00a0 The library attempts to turn the very messy synchronous environment of avr programming into a javascript-like single threaded asynchronous one.<\/div>\n

Is your progress on schedule or behind? If you are behind, what actions will be<\/em><\/div>\n
taken to catch up to the project schedule?<\/em><\/div>\n<\/div>\n
I think we are very behind on the firmware side of things, but we are devoting a lot of time to it now to get it working asap.<\/div>\n
<\/div>\n
What deliverables do you hope to complete in the next week?<\/em><\/div>\n
Finish the driver I am working on and have the basis of inter-tile communication working on several tiles.<\/div>\n","protected":false},"excerpt":{"rendered":"
