Hack a Day
Our days by the pool are behind us for the year. But playing pirate ship with a 2-year-old does sound like quite a bit of fun. That’s why [The Stone Donkey] built this pirate cannon prop complete with firing sounds. The simplicity of the design is pretty brilliant. Three segments of PVC and five fittings make [...]

This set of PVC cranks make you work for your game of Puzzle Bobble, also known as Bust-a-Move. It uses a little cannon centered at the bottom of the screen to pop bubbles based on like colors. There is a cartoon character that cranks as hard as it can to aim that cannon, and this hack [...]

When we posted our redbull firing pneumatic cannon, we got a pretty quick email from [Ryan] at Minot Makers. Apparently, they were working on a redbull cannon as well. Theirs, however, has a completely different use. They intend for this to fire a redbull with a gentle arc allowing you to simply catch and drink [...]

The term “just enough knowledge to be dangerous” comes immediately to mind with this one. The official description is “a large scale pan and tilt propane Flame Effect” but that hardly does this thing justice. The Anti-Sanecraft ARTillery Cannon is a three-barrel fire cannon that can move around like its namesake and launch massive propane [...]

After hanging around festivals and burners for a bit I decided that it was finally time to show my stuff and actually build one of these crazy fire cannons everyone is always talking about. The easiest way to go about this would have been to just follow plans from any given website: replace the valve [...]

Every year, Qualcomm hosts the “Battle of the Schools.” This year the goal was to build homemade contraptions that would be judged on how cool they are. [Doug DeCarme], [Shaver Deyerle], and [Zach Rattner] – three Qualcomm employees at Virginia Tech – built an Android controlled t-shirt cannon for this event and ended up tying with Michigan [...]

[Henrique] wrote in to tell us about his time-lapse photography hack. Triggering of the camera is done via CHDK, or Canon Hack Development kit. This experimental kit allows Canon Powershot cameras to run scripts as well as other neat features without permanently changing anything. User scripts for this hack and others can be found here.

[joe] and [ryan] built Thumper for their high school FIRST robotics team. The cannon itself is a solenoid-fired compressed air launcher that gets its juice from three large PVC tanks stored in the box below the turret, and the cannon is able to be fired nine times between visits to the air compressor. It was [...]

As an amateur radio enthusiast, [Andrew] sometimes has to set up impromptu antennas up to 160 meters in length. The easiest way to get these antennas off the ground is to drape them over trees, a feat normally accomplished by lofting fishing line into the air with a slingshot or bow and arrow. [Andrew] thought [...]

Although this isn’t the first pneumatic air cannon to be featured on HAD, this “paintball shotgun” is certainly one of the coolest. While most air cannons have little practical use besides looking awesome and being cool to play with, this cannon, according to it’s maker, has actually been used successfully in actual paintball competition. The [...]

[Nighthawkinlight] has made his own palm cannon to shoot Airsoft pellets. His process, which he guides us through step-by-step in the video after the break, definitely invokes MacGyver buy using commonly available parts in a way they were not intended. He starts with a barbecue lighter, removing the screws and plastic housing to get at the clear [...]

[Jeremy] wrote in to show off his latest creation. he has built a two barrel pneumatic air cannon. Eschewing the traditional approach of having a single barrel and pressure chamber for his spud gun, [Jeremy] wanted to have a double barreled version. Since he was doing this pneumatically, he had to rig up a way [...]

The newest addition to the Skynet armada is this 10-barrel t-shirt cannon. It’s capable of storming the battlements at over twelve feet per second with a firing rate of three T-shirts per second (ooh, is that cotton?). The members of Team 254, which is hosted by Bellarmine College Preparatory School, built the robot over the summer. This [...]

In a hack worthy of the flick Kick Ass, [Chein] built this arm-mounted light weapon. The lamp in the palm of your hand has a ring of LEDs for a nice glowing effect, but the real story is the xenon bulb at its center. The flash capacitor and charge circuit from a disposable camera are [...]
