Turtle Modifications Wishlist

Now that I have a fair grip on what I can do (controller-wise and construction-wise), I figured it was about time to list out the changes I’d ideally like to make to my little cardboard tumblebug model.

Structural

  • I hate how wide the track is. The current width was originally decided on out of simplicity—it is wide enough to accommodate the entire possible range of the radius variations that result from the height change. I’d like to trim it approximately in half all the way around the course.
  • I like the idea of significantly cutting down on the solid cardboard wall that currently supports the track. Either I could cut out sections to simulate a more traditional support structure or I could replace the cardboard support entirely with wooden dowels.
  • The arms that connect the ride vehicles to the drive shaft currently feel like massive overkill. Cutting down the support structure there would be nice as well.
  • If time allows, paint and a lot more decoration would make a massive, massive difference.

Mechanical & Electrical

  • The main aim of revisiting the Turtle is, of course, to motorize it. I will need to cut out the center of the bottom platform and build a structure to hold the motor in place.
  • A platform will need to be added under the existing “ground-level” to accommodate two hummingbird boards and the wiring.
  • Each hummingbird board can control six LEDs (2 three-color and 4 single-color). That gives me 12 LEDs to work with in total. I believe the 8 single color LEDs will be used around the ride itself and the 4 three-color LEDs will be used on a sign of some kind.

Part 2 Final Project

After surfing the internet and thingiverse, I have found the propeller that I am going to use. I decided to print the propeller using supports because of the shape. It took me a while to break all of the supports off. The Propeller! The Motor Now to mount the propeller to the motor! I spent […]

I spent a while trying to figure out how I was going to mount the propeller to the motor. After I remembered that I had left over JB Weld from my truck. I decided that the JB Weld would work and to give it a try. JB Weld mixing Above is prior to mixing the two chemicals together. The product drying Below is after everything put together and is now curing. In a few days will upload a picture of the finished product! IMG_1527

Start of my final project

For my final act as a UMW student in the think lab will be to create a wind powered generator. I have always thought about creating one but I have never had the time or money to make it happen. So for this I am planning to create miniature wind generator. Parts list: Small left […]

For my final act as a UMW student in the think lab will be to create a wind powered generator. I have always thought about creating one but I have never had the time or money to make it happen. So for this I am planning to create miniature wind generator. Parts list: Small left over motor 3D printed propeller JB Weld PVC or CPVC piping and fittings Electrical Wire Male USB plug As of right now I think is this all I am going to need to create this. I will revise this list if something else comes up!

While surfing the internet the other day I came across this image. I couldn’t help but to think of Rosemary and her yarn stash.

Selecting the Hummingbird

For my final project, I am going to motorize and decorate the Turtle model I previously wrote about. Nothing says “fairground” or “amusement park” quite like blinking colored lights and the loud sound of a motor buzzing in the background. The biggest question I’ve encountered thus far has been whether I should use a Hummingbird controller or …

For my final project, I am going to motorize and decorate the Turtle model I previously wrote about. Nothing says “fairground” or “amusement park” quite like blinking colored lights and the loud sound of a motor buzzing in the background. The biggest question I’ve encountered thus far has been whether I should use a Hummingbird controller or the more ubiquitous Arduino board. After some research, I have decided on the Hummingbird. Why? Mainly because the bulk of the added capabilities of the Arduino come with the addition of breadboards, additional shields, etc. While I would like to control more lights than the six the Hummingbird offers, without diving in a lot deeper than I’m looking to do, the Arduino’s capabilities out of the box are similar.
