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.

Powershot DG25: An epic Lego dart gun

Sneak peek

Recently I was working the sound at the Vacation Bible School (VBS) at my church when I noticed that two of the Mylar balloon sea creatures that were decorating the sanctuary escaped and floated up to the ceiling. Being an expert at Lego weaponry, this was a great opportunity for me to put my skills to good use. To take down the balloons I built a simple Lego gun that launches darts primarily made of mechanical pencils. With its simple but strong structure and large rubber bands stretched to the limit it can launch those darts hard enough to punch right through a Mylar balloon after flying 20 feet straight up. Presenting the Powershot DG25:

And here's the best part: I made instructions for my blog viewers!

Here they are:

Epic Lego Shotgun Sneak Peek

I recently had an idea for an awesome Lego gun, so I constructed a magazine for it. The magazine has 6 barrels that you load with 3 3-unit beams each, and each is held in the cocked position by a pin that stick trough the side of the magazine. The gun will be semi-automatic, each time you pull the trigger you pull out one of the pins, releasing one of the barrels and ejecting the pin from the side of the gun. This makes it shoot (because the barrel shoots the 3 bullets) and eject a "shell" at the same time, which will be pretty cool.

Update: I now have it in full operation, semi-auto. It's pretty sweet.

Ultimate Lego Gun Sneak Peek

Here's a sneak peek of my new Lego gun, a rifle with enough power to destroy a 4 layer Lego wall at 10 feet (3 meters). Most of my other guns consider themselves powerful when they can destroy a 4 layer wall at point blank range!

Robotics Competiton Hint

In case you were wondering how to make your robot grab cubes and lift them to score with only one motor, here's a simple mechanism that is able to to both. It isn't robust enough to wok well in the competition yet, but with a bit of modification it could work quite nicely.

Hint:

Pump-Action Lego Rifle sneak peek

If I told you all about it, it wouldn't be a sneak peek, would it? =)

I'll tell you this much: It's a pump-action Lego rifle. But you probably already guessed that from the title.
