Project
Laser
light show driver
4/10 Project start: dual DACs at 1-3kHz
Prelab:
1) Draw a still picture with greater than 16 points (=N). Print out (in excel or such) the array of x-y
points in your still.
Points must be on 16x16, 8x32, or 32x8 grid (integer values)
Plot the points in excel or such. Draw
lines from 1st to 2nd, 2nd to 3rd,
etc. points.
Indicate numerically or via linewidth the brightness of EACH line.
2) Draw a draft of an animated light show you think would be good to do.
You don’t need to include brightness on each line, but think about how that
figures into your animation.
Sketch out each frame. Don’t need points
yet. Keep in mind limited grid.
4/17 Initial images: dual offset DACs with active filters run by parallel port and viewed on
scope.
Prelab:
Still images converted to single column of 0-255 numbers.
4/24 Testing of
animation on scope. Scanner
testing and adaptation of electronics to scanners.
Prelab:
Animation converted to multiple columns (one per frame) of 0-255
numbers.
All frames must have same number of points.
5/1 Circuit clean-up, testing, and prep
for laser show. Laser
show trial.
5/2 3-4 Laser light
show in EPS atrium.
Here is m-file for Matlab to simulate laser show drawings: LaserShowSimulator
Here is LabView
VI to turn 1-column (still)
or multi-column (multi frame animation) of 0-255 numbers (tab delimited)
into parallel port output: MSU_LaserShow_5.vi
It allows you to set sample rate (in
microseconds per sample) and frame repetitions.
8-bit parallel port output can run 16x16, 8x32, or 32x8 laser show.
Here is a sample of a single column of
0-255 text file (not an image): fake
1D 123_255data.txt
Useful for testing parallel port
output and timing.
Here is data sheet for 74LS240
: datasheet74ls240.pdf
Each group will produce one circuit
board that can run both group members still and animation images.
So group has to decide if they are doing 16x16 or 8x32 images.
8x32 is easily converted to 32x8 and thus both formats are compatible within
one group.
POWER BOOSTER FOR LASER LIGHT SHOW
We do not
have the appropriate audio amplifiers in stock in the PEDL, so the plan will be
to put a power booster in our circuits.
READ the section in H&H on “power booster” (page 186) in Chapter 4.
Decide if you want to use figure 4.21 or 4.22. Decide where it will go in your circuit.
Do you want to put in a new opamp and do you want to
integrate into current opamp?
Draw final stage of your laser light show driver with power booster
as you want to implement it.
I will have the appropriate transistors picked out by Thursday.
Project Write-Up:
You are responsible for a full write-up of the lab, including documentation of:
overall motivation, preparation, testing
of all components (how tested and results, including computer interface),
diagrams, performance, mistakes made, testing of x-y scanner,
reconfiguration of set-up and active filter to adjust for x-y scanner,
observations (compare and contrast your excel/Matlab drawing, oscilloscope
image, and laser show image),
performance of x-y scanners, explanation of computer interface (x-y image to parallel
port output to DAC).
In conclusions, include photos of laser show and
extensive comments on what was good and bad about the project and ways to
improve the design/project.
Must be neatly written or typed. Neatness counts in grade. That includes circuit board.
Write-ups are to be done individually.
