Various Projects I Have Worked On

These are some of the side projects I have worked on. Below are write-ups on them.

Arcade - Related

Project Name: Picture: Write-up: Brief Description: Misc.
PERISCOPE, a TTL arcade game. How a 14/15-year-old designed a TTL arcade game. I designed / built this arcade game when I was 14-15.
I logged about 300 hours on it. (297, to be exact.)
It cost more than $2,300 to build.
It has no CPU, and about 1.75K in PROM memory!
Designed / built during 2017-2018
Garden Of Eden Pinball Machine How an 11-year old built a full-size pinball machine. I designed / built this pinball machine when I was 10-11.
I spent over 500 hours on it.
It cost over $5,000 to build, with about $650 of it in shipping costs alone.
It houses 3 Arduinos and over 500 feet of wire.
I have not topped this project in WOW-Factor yet, probably because of the combination of difficulty and young age...
Designed / built during 2014-2015
Cloning Atari's Space Race Yes, I am cloning Atari's Space Race. (In progress)
Right now, I am trying to figure out why the 14MHZ clock is running closer to 18MHZ. That means the game is doing about 80 frames a second, and my monitior can't handle that.
I have done the math, and if the problem persists, putting in a ~10MHZ crystal should fix the problem.
Cloning Atari's PONG Back when I cloned Pong. I cloned Atari's PONG back when I was 11. It... looked like PONG. It had a bunch of problems that I never fixed. Knowing more about TTL, I think I know what I did wrong. 2015?


Project Name: Picture: Write-up: Brief Description: Misc.
The Pocket Encouragement Device Picture: Write-up: I know we all feel discouraged at times, so I designed a device that would provide Biblical encouragement at the press of a button.
I basically filled up the ATMEGA328P's memory with 78 bible passages. (Well, about 30 bytes were left over...)
I built this when I was 15.
Designed / built during 2018
A Perler Bead Sorter Picture: Write-up: In the last 2 weeks of school, it was announced that we were going to make little find-it like things...
...And we were going to use perler beads to fill them.
Someone apparently thought it was a good idea to buy (I did the math, I think it was 138,000) unsorted beads.
They did that with the intention of having students sort them in class. That ended up occupying our next few weeks.
Ahh... how did that phrase go... Penny wise but Pound foolish?
I did not want to spend all of my science classes (yes, science class...) sorting those miniscule, 38-color beads.
So I designed a bead sorter. I went through 2 designs, the second one worked, but it broke after sorting 3 black beads...
Designed / built in 2017
My 8x8x8 RGB led cube. Picture: Write-up: This project had several firsts for me:
  1. First major project I've done entirely by myself.
  2. First project involving TTL. (24 SN74595 shift registers.)
  3. First project I had to order components in multiples of 100.
  4. First project I had to design and order circuit boards for.
  5. First project to exceede 50 pages of arduino code.
I built this when I was 11-12
It cost about $1,500 to build, and I spent about 200 hours on it.
Designed / built during 2016-2017
Autonomous Rover Picture: Write-up: A little rover I built for school with the purpose of navigating mazes.
First major project I did. It had several infra-red sensors to make sure that it did not hit any obstacles.
Kinda funny when you think that my school project next year was a full-sized pinball machine!
While it may seem unimpressive, keep in mind that I did this when I was 9-10!
Built during 2013-2014


Project Name: Picture: Write-up: Brief Description: Misc.
Electric Go-Kart Picture: Write-up: This project was a flop. The goal was to learn how to use a CNC machine, but my Dad didn't finish building his before the end of the school year, so I had to hand-carve something.
We all know how bad I am with art, (I seem to be limited to curves, trapezoids and ovals.) and that, with such a lack of time to accomplish it, was probably why I failed so miserably.
On the bright side, I am pretty good with advertising my projects, so I still managed to wow everyone at the exposition anyway.
