The main parts of this project are:
-C2000 family microcontroller (tms320F28379D) (there's a launchpad for this also)
-WS2812 LED strips
-2 RN-42 modules
-300w power supply
The code is available on github. This includes the emulator, the bitmap parser, and the microcontroller code.
In the links the team website can be found with senior design documentation, more pictures, code dumps, and the laser files. Warning: Data usage
The custom board isn't required in a replication, the launchpad can be used.
This is a prototype made for our team's Senior Design project.
For a independent build, the main things would be to eliminate certain ABET requirements.
Then find a better way to implement the dividers for the pixels.
The code, the framework itself is useful but there's a number of improvements to be done.
Some build pics:
ws2812 led strips, ordered off ebay
Testing various heights and their effects on the light dispersion
Quick testing of the LEDs + using an internal reflective material vs not
Some early test cuts, and double triple checking led spacing
Thus the start of the painful staining begins
Waiting for round 1 of the stain to soak/set
All the led strips on the backboard for being inserted into the table. This pic is pre-testing
Main slats post-staining with ducting tape
middle of assembly
almost finished with assembly, interior shot to show the ducting tape
re-wiring all the strips again
cable blob for the power supply
Finished rewiring and trying to collect the cables
one of the first power on tests, with various types of plexi for testing
First early demonstration of the table working
first kludge board, worked mostly, ABET requirement
rev 2 of the board, minor kludges, works good enough
Final team shot, after everything finally settled down.
