Lego Battle Tank with working turret

The video for my new tank is finally completed. For those of you who don't know, it is a tank that has a turret that can rotate and shoot. Sorry for some of the footage being poor quality, I already spent a lot of time on this movie without trying to re-shoot the footage more times.

Stop-Motion Title Animation

For fun and to add an extra flair to my videos I created an animation where the words "DroidFreak Enterprises" build themselves out of Lego Technic pieces. I plan to incorporate this into the introduction of my subsequent videos.

For those of you who wonder how I did it, I built the words first and then took them apart in reverse, taking pictures periodically as I went. When I reverse the order of the pictures it looks like the words are building themselves.
I do something similar for all my instruction videos: I take apart the set step by step and take pictures that I reverse to make instructions.


Proof of Concept: Tank with rotating + firing turret

After YouTube user MoshiB9865 commented on one of my videos mentioning his "Lego Airsoft Gun", we had a brief conversation about the mechanism (which used custom sector gears) and I became convinced that there must be a way to do the same thing with only Lego parts. He also mentioned integrating it into a tank.

One thing you might notice about me (especially in Lego weapons) is that whenever I learn that someone tried to do something but failed I try to do it. It's not that I mean to prove that I'm better than them, it's just that I get struck with inspiration and I want to make something that I know will be cool. In this case, my plan is to build a Lego tank with a turret that rotates and fires using a pull back and release mechanism like MoshiB9865's "Airsoft" gun.

I managed to construct a simple proof of concept for the tank, including a working version of the gun. The tank's drivetrain has roughly 0 ground clearance and the gun has much less power than I want from the final version, but it still illustrates that the design is sound.

DroidFreak Enterprises HQ - June 2012

This is a test of a new video style (a freehand update video) as well as a chance to show off two of my new projects. One is a shotgun attachment for my Tech Target Eliminator (Nerf pistol) that allows it to fire 5 darts at once. The other is a full-fledged Lego Nerf gun, a Lego contraption that shoots Nerf streamline darts out of Nerf clips. It is a semi-automatic flywheel blaster like many recent Nerf guns, but it's made out of Lego and I'd like to think it's better in some ways. If you like/dislike this video style or you want to see more about one (or both) of the projects, feel free to leave a comment on this post.
