Bluetooth Rally Racer

Rally Racer is the successor of Rally Rac3r. The difference? This Rear Wheel Drive race car is a tremendous success. As complimented by Karl4123, this vehicle has “sleek and stylish looks.” It is geared up 36:12 or 3:1, and it is decently quick with decent torque. Many styling cues have been added. Why is there no InfraRed Sensor, you may ask! Well, thank you for asking! With the help of Builderdude35’s tutorials, Rally Racer drives via Bluetooth! Rally Racer’s Intelligent Brick acts as a receiver, and a second Ev3 Intelligent Brick is the remote! In this way, I am able to control Rally Racer from 200 feet away. I also incorporated bluetooth RC into prototype versions of my 2010 Cadillac CTS-V ReplicaContinue reading

Looking Back At 2015

The concert hall at the Sydney Opera House holds 2,700 people. This blog was viewed about 31,000 times in 2015. If it were a concert at Sydney Opera House, it would take about 11 sold-out performances for that many people to see it.

The busiest day of the year was November 10th with 525 views. The most popular post that day was EV3RSTORM.

Modify Your LEGO Tires For Performance


This tutorial shows how to increase the firmness of your LEGO tires! If your Mindstorms or Technic creation is pushing the tires down like a flat tire due to heavy weight, or if you want less rolling resistance from squishy tires, you’ve come to the right place! I hope this tutorial is a big help!  Continue reading

CTS-eV3 | Cadillac CTS-V Replica

CTS-eV3 is a Lego replica of the 2010 Cadillac CTS-V. With Rear Wheel Drive, lots of speed, and more than adequate torque, this motorized creation is like the real car. Having been over half a year in the making, there has been many trial-and-errors (including chassis, drivetrain, and exterior redesigns). But I am quite satisfied with the final outcome! CTS-eV3 has a 4.5:1 gear ratio (minus the differential), accomplished by driving a 36 tooth gear meshed with an 8 tooth gear in a unique setup. Actual speed is a few tenths under 4 Kph! This two door coupe has been relatively replicated, including the visible V8 piston engine along with the Corvette inspired supercharger!  Continue reading
