Here's a silly little video I made last year and never shared. Both trains are controlled from my phone via my open source Bluetooth receiver. Stay tuned for the bloopers at the end. Hope you enjoy!

I really liked the look of 42005 Monster Truck, but wanted to motorize it. I found Splat's motorized version, which helped kick me into gear and order the necessary parts. Once all the parts arrived from several BrickLink orders, I started thinking: why not try motorizing the model without following Splat's build? Later, I'll tear my design apart and try his build. So here is the result of my tinkering. Motorized LEGO 42005 by niaconis, on Flickr I've been able to retain much of the look (and build) of the official LEGO model. Motorized LEGO 42005 by niaconis, on Flickr The battery box is easily removable and slips into the empty space at the back of the truck for use. Motorized LEGO 42005 by niaconis, on Flickr It is possible to charge the battery without removing it from the vehicle. Motorized LEGO 42005 by niaconis, on Flickr A BricksTer Open Source Bluetooth receiver prototype is mounted to the frame using technic pin/axles and half bushings. I found I needed the bushings because the holes are sized for studs, which have an ever so slightly larger diameter than technic axles. Motorized LEGO 42005 by niaconis, on Flickr A servo motor mounted in the front steers the front wheels while an L motor mounted at the back drives the rear wheels. I wish I could have geared down the drivetrain more, but I found I currently have no 48-tooth gears. Motorized LEGO 42005 Steering Demo by niaconis, on Flickr In the animated gif, you can roughly see how it is steered with an Android phone. And finally, I present a short video showing the monster truck driving around in a local park, controlled by the new proof of concept accelerometer input for the BricksTer Android app (which you can also see in the gif). Thanks for reading this far! I appreciate critique, comments, and suggestions!
