KI7TU's Reference Page -- Projects
This page is for various projects that I've come up with that you
might be interested in.
I'm also including here links to the files for 3-D printed
things that I've "published".
You're more than welcome to duplicate them, though I would
appreciate a note saying that you've done so.

Folks letting me know that they've built something I have designed
will encourage me to put up more designs.
Sewable 5mm LED Mount
I've been working on a "Flashy Santa Hat", but that's
still a ways from being ready to publish.
In working on that, I came up with the need to attach a
standard 5mm LED package to the cloth of the Santa Hat,
so I designed a mount that can be 3-D printed.

I should reiterate here that this design is intended to
be printed using a flexible plastic such as
NinjaFlex from Adafruit.
Projector Elevation Adjustment Disks
I go to a fair number of club meetings, and many of them have
Most of the clubs can find better things to do with their limited
funds than buying the "latest and greatest" projector,
and so are using one that's typically several years old.
Although nearly every one of these has some sort of
elevation adjustment screw, they're usually either broken
or don't go far enough.
(Many times they're broken and even if they did work, they
wouldn't go far enough!)
So, there is usually a mad scramble to find something to prop
up the projector.
If the meeting place is a restaurant, often times things like
jelly packets or honey packets are used, but this can lead
to a sticky situation.
So, I designed what I call "Projector Elevation Adjustment
There are three different hieghts, roughly 2mm,
4mm, and 8mm.
They have a ridge on one side, and a groove on the other, so
that they'll stack and won't slide off, and the foot of the
projector will fit nicely into the one on top.
I consider a set to be 2 each of the 2mm and 4mm ones,
and 6 or so of the 8mm disks.
Caution: Do not use PLA to print these, as it
gets soft at about 50°C (122°F) -- some projectors
can get them that hot, and it's VERY easy to reach that
in a parked car during the summer.

Flashy Morse Badge
Inspired by those paper badges that say "Hello, my name is",
I designed and built a computerized badge that sends a Morse code
message on LEDs. Mine says "HELLO I AM CLARK KI7TU",
with features like varying colors every time it repeats, and
mesauring ambient light to adjust the brightness.
You can look at a detailed
description and instructions,
the parts list,
and the software.
