Instructables is one of the best sites
on the web for posting your home projects. For those unfamiliar, people submit
small instruction manuals on how they built their projects and those are then
posted under the appropriate category on the main site. You can submit anything
from recipes, to costume designs, to home electronics rigs. Even better, they
often host contests for people who submit the best projects given the contest
scenario (holiday themed, using a specific medium/material, geekiest, etc.).
The downside to sites like Instructables
is that there is no standard template for submitting your project and people
are mostly free to include whatever they want. Several of the projects I have
been interested in ended up being extremely lacking in the actual instruction
part. Many people don’t bother to post their complete bill-of-materials (BOM)
with a description of where you can find the parts or post a schematic for you
to follow. It can get frustrating.
At one time I considered submitting my
pumpkin display to Instructables’ Halloween contest, but given what my final
product turned out to be I didn’t think it was worthy. Instead, I am going to
post my build log across a few separate entries on this blog. I have decided to
take a backwards approach by showing you what the final project looked like and
then showing how I went about assembling everything. I will try to post as many
pictures as I can for the visual learners out there. However, I first want to
encourage you to go back and check the posts I did about my original idea so
you can see just how far away I ended up from that original plan. Plus, I will
be assuming in future posts that anyone reading them will have some context concerning
what I was trying to build.
In the coming days you can expect to see
a few different entries related to my project. The first will go into detail on
how I created the form factor (i.e. carved the pumpkins and created the bases).
Next, I will show the circuitry I used including the theory of operation and
the construction of the circuit boards as well as the code I used to run the
animations – I may split these up into a few posts. Last up I will show my BOM
with some advice on recreating the project and areas for improvement.
Maybe next Halloween I will try to
improve on my current designs, but until then…screw Flanders.
