This is it! My Jato 3.3 nitro is now 100% Boca Bearings! It's time to hit the road and get some telemetry data. Here is a video of the first few runs to test the telemetry received from the Traxxas app.

Test Speed Run App Inlay

After a few runs it was evident that the power-to-ground was very consistent. If you notice the car just wanted more speed and the last run I did not apply the brakes in time; only to spin the car into a free-way at the end of my run (note the trailing words of my excitement :).

To confirm the consistent power I started up my Traxxas App and began recording my "dashboard". The dashboard is a summary of all the sensors on my Jato 3.3. As a quick summary here is what the dashboard is measuring at the receiver:

Autonomous Rover Part 2: The MINDS-i 4X4 3-in-1 Robot and the FlySky FS-T6 Transmitter

The video above is just a quick overview of the parts that came with the MINDS-i 4X4 3-in-1 robot kit.

Design:

The MINDS-i Robot has finally arrived here at Boca Bearings. It's a fairly large package with many pieces. The package is shown below.

The robot has three different build options. The build options are seen on the front cover of the manual. The design that we are going to go with is the one shown below.

Vintage Toolbox 3D Printed: Part 1 -- Design and Research

Below is a new project for Boca Bearings http://www.bocabearings.com/ where I will be constructing a 3D printer with in a Huot toolbox that was once used as a "Blower Repair Kit."

One of the main features that makes this toolbox a good candidate for a printer over other toolboxes is its fold-down front. A spectator is able to view the print from both the top and the front while also allowing extra room for the print bed.

When I begin a design for a printer or other multiple component machine, I do not start in the computer or even a sketch pad because there are too many things going on for me to even know where to start. I find it helpful to begin "mocking up" a model, often using the parts I will be building with such as bearings, pulleys, guide rails, stepper motors, a hot end and spare 3D printed parts from past builds.

Autonomous Rover Part 1: Project Proposal

Purpose/Goal:

The purpose of this project is how to learn to create an autonomous land vehicle that can be programmed with waypoints for destinations to travel to. I will learn how to also add ultrasonic sensors to the rover to avoid crashing into any obstacles on the way to its waypoints. This project will also help me learn more about RC cars such as the motors and the ECS. I have never had experience working with any type of RC cars and their components. I will learn things such as the frame of the RC car as well as its suspension. I could probably learn how to change certain parts of the RC car to get different results. I’m into cars and learning on working on cars so this project will help me learn more on a smaller scale. I will also learn how steering works. Then maybe I can apply this concept to a future project such as go kart. I will also learn how to use a multi-channel transmitter to control the RC car when it’s not in autonomous mode.

Initial Design Concept:

For the design of the Rover I will be using a platform already designed by MINDS-I. The model in particular will be the 3-in-1 4X4 Robot as seen below.

Land Speed Bike 100cc Modified

I will be running in a land speed bike competition using an 80cc Minarelli V1 using alcohol fuel -- competing in the 100cc modified production fuel class.

Time to set some world records.

Land speed racing has been a huge interest of mine for a long time, and now I am finally able to compete. I'm building the Minarelli V1 with an 80cc polini top end that has been race ported and converted to reed valve and running on alcohol.

I'm also very honored to have Boca Bearings, CryoHeat and MSD performance as sponsors!

I will provide updates as the build proceeds. So far I have gotten the crankshaft cryo heat treated by CryoHeat and rebuilt by Mr. Crankshaft. The main performance in these motors comes from the crankshaft. Since this beast will be running on alcohol, I needed to build a very strong crank.

Thanks to the deep freeze hardening and micro polishing from CryoHeat, and the brand new journal bearing from Boca Bearings, this engine will run strong!

Traxxas TQi Telemetry Radio and App: Part 2 -- Bearings Replacements

It's been a long winter and good weather is finally upon us. This means getting the Jato ready for a faster season. Thank you goes first to Boca Bearings for providing all the bearings for this Jato.

The replacement of these bearings has been made more convenient with the ever-precise and

super-sharp metric tool kit.

Part 1: http://bocabearingsworkshop.blogspot.ca/2015/04/traxxas-tqi-telemetry-radio-and-app_27.html?m=1

This part of the workshop will be the replacement of all 33 bearings with Boca Bearing's Orange Seal Series of bearings.

A) The Bearings:

The bearings are of ABEC 7 grade (American Bearing Manufacturers Association). This is a measure of eccentricity or roundness. It is measured at 0.0025mm. A regular bearing measures at 0.0075mm. There can only be one higher rating of ABEC 9 at 0.0012mm. This means only the best continuous and precise movement which allows the possibility of pushing your RC to go faster. Remember bearings are not a source for "more" power, but it allows for more power transfer to where it counts! As a simple extreme comparison; think, how fast would you go with square wheels?

3D Printed Robotic Hand: Part 6 -- More Programming and Debugging

With how I left things the last time, I wasn't getting the full range of motion of the servos. So this wouldn't let me close the hand all the way. Some fingers barely moved at all. So I did some more programming and debugging the programs for the hand and glove. But I still couldn't get the full range. Then I just decided to just rewrite the whole program this time without having the need to use the Adafruit Servo shield to control the servos. I referenced
