Boca Bearings Workshop Weekly Update 6

Our old Powerwheels chassis has taken a beating over the past two years now. With that being said, the team decided to create a new chassis and retire the old one. The layout of the new frame is a rather simple design, yet it is structurally sound enough to get the job done. The rear end of the old frame will still be used in our newer since it seemed to be the only part of the old chassis that was not bent or structurally defected.

Maker Faire Orlando 2017 - Part 2

Ever since attending the Mini-Maker Faire in Miami this year I have been thoroughly excited for Orlando’s event. There were so many cool projects and people this year and it was awesome being able to see everything that was on display. There were three things that really stood out as I browsed the Faire. Outside of the Workshop I am the president of a robotics club at a local university, and so it should come as no surprise that my favorite things to check out were all the amazing robotics being shown. From FTC builds to Battle Bots, Astro droids to Repair Droids there were all amazing. Two robots in particular that stood out to me were the Renaissance Robotics FTC build and steampunk R2 Droid.

Maker Faire Orlando 2017 - Part 1

Maker faire Orlando was an absolute blast to attend. It was amazing to see all the different forms of creativity that went into what everyone had to show. There were different types of computer builds, circuitry, physics projects, and so many different forms of art. I personally was keeping track of the Powerwheels competition that was held at Maker Faire. Each day of Maker Faire encompassed a different race/event for the Powerwheels competition. The first day of Maker Faire required that all the racers had to do preliminary qualifications, three sprint races, and a moxie lap.

Hybridized Garrett Boca Bearings Turbine - Part 3

I have been extremely busy in the workshop recently and trying to make more progress on the turbine has slowed down a bit since most of the turbine unit is disassembled. The last part of disassembly of the turbine deals mainly with the CHRA and removing the journal bearings completely. Tools necessary for the task:

1. Small snap ring pliers
2. Patience

Hybridized Garrett Boca Bearings Turbine - Part 2

The initial teardown of the turbine started with the larger and more basic components of the unit such as the housings, drain pipe, and other various components. It was then that I was left with just the CHRA and its internal components. So now I began the teardown of the internal parts of the turbo.

Necessary tools:

In the perfect physical world, there would be no gravity or no coefficient of friction. As we all know that is completely unreal. With the idea of gravity in mind, it would be in everyone’s best interest to try and reduce the coefficient of friction as much as possible. Reducing the coefficient of friction in general helps improve efficiency and performance of almost anything moving (i.e.: bearings, lubrication). Now you are probably asking yourself why should someone or anyone know this vague information. The answer is that this same basic principle applies to your daily activities whether you notice it or not. The easiest example of this is the car you use to commute to and from point A&B. To demonstrate this theory of reduction the coefficient of friction, I will be inserting new ball bearings into a 30-year-old turbo charger that is used on gasoline and diesel engines.

Boca Bearings Workshop Weekly Update 5

The first new project I’ll be talking after Maker Faire Orlando is a sorting machine. The goal will be to sort skittles (or any uniformly shaped and colored candy) into separate cups. The project is heavily based on the fantastic work done by Willem Pennings on his blog which you can find here: There have been other sorting machines similar to this, but I think Willem’s looks the best and so that is the design I’ll be drawing from the most. Over the last week I’ve put together a parts list and begun to CAD the mechanical aspects of the project. Below you’ll find a link to my list of components and the cost so if you would also like to make one you have a good starting point. Once I finish modeling the system I’ll make the files available so that anyone can reproduce the project as well.
