One of the more important aspects of our design is that a single IR receiver needs to relay the signal it receives to multiple Arduino boards. Recently we tested such a set up. After a fairly large amount of tinkering we were able to get the receiver to output to three different Arduinos with limited interference. This simplifies our task of wirelessly controlling the hovercraft. Since the IR receiver plays such a crucial role in our design we decided to build a tower to mount the IR receiver on. The design for the IR tower can be seen below.
This weekend other aspects of the hovercraft have been nailed down. For example the LED array designs have been completed as well as the structure of the LCD screen code.
There are still a few decisions that have to be made. Perhaps the most tedious of these is deciding what will be run off of each board in order to ensure we do not exceed the maximum current the Arduino can output.
There is still a lot of work to be done before December 4th despite the fact that the majority of the design work has been done. A significant amount of soldering and circuitry are primarily what remains.
