As promised, this is a short update on the progress of my
Halloween display project. So far, I have managed to get one chip programmed
using Microchip’s new MPLABX IDE, the HI-TECH C compiler, and a PicKit 2. I haven’t
ever actually programmed a microcontroller with C before and MPLABX is still in
beta so it took some time to get familiar with setting up even a basic LED
flash program (mostly due to the fact that I don’t entirely know what I am
doing). At the moment I am only running simple timing loops to control the
animations, but I hope to get more functionality in the next couple weeks. My
plan is to hardcode an animation sequence into the micros as a backup in case I can’t get my additional features
built in before Halloween. We will see how things go.
Now for some pictures. Below are three pictures of the
pumpkins as they look right now. I found four faces online (since no one gave
me any suggestions) that I more or less copied for my own use. The pumpkins
themselves are hollow, but the foam walls were actually about half an inch
thick in certain areas so getting a decent pattern out of them takes some
effort. I am pretty happy with the way they turned out though.
My color choices below aren’t final yet. I am still
experimenting with colors and suggestions from friends so leave comments if you
have suggestions. The colors are kind of hard to make out in the photos, but
they look much better in person. From left to right they are: green, red,
white, and blue.
Since these will be outside in the dark I took a night shot
too. One thing I am pretty proud of is how even the light looks inside the
pumpkins. I found some diffusers at our local Michaels that I think will really
work well in the final project. There will be more to come on these in my final
bill of materials.
That’s all that I’ve got for this update. I am going to
start working out some lighting patterns and planning out their timing with an
Excel spreadsheet for event scheduling. In the interest of open source, I will
post all the materials I used to create the final project once I wrap things
up.

Looks really good dude. The design is clean and the lighting looks evenly dispersed. I like the range of emotions as well.
