Surplus bazooka converted to shoot firework artillery shells

bazooka_fireworks_mortar_launche

[Mark] and his friends love fireworks, but got tired of the traditional ground-launched mortar rounds, so they decided to spice things up a bit.

A while back he purchased an Army-issue bazooka at a gun show but didn’t use it for much, so it sat unused for about 10 years. He dug it out of storage, then hit up his local hardware store for a few lengths of PVC piping. He cut the pipes to size and then used his 3D printer to build a couple of parts to securely mount the PVC pipe into the bazooka’s shell. With his standard tube, he can shoot 2” mortars from the bazooka, but says he can add a second nested length of PVC to allow for smaller rounds.

Obviously this sort of setup can be quite dangerous if it is mistaken for actual weaponry, or if your fireworks were purchased from some guy’s trunk at a highway rest stop. [Mark] and his friends have taken some precautions when they use the launcher, but this is still clearly a risky enterprise.

That said, we think its awesome, and if anyone has a spare bazooka sitting around, feel free to send it our way!

[Correction]
Not a bazooka, it’s an AT-4. Thanks to those who pointed it out.

Bottle rocket POV video

pov_fireworks_video

It’s a holiday weekend, and much like you, we’re taking a bit of time to relax and kick back a few drinks while we mingle with friends and family. Obviously, one of the bigger events this weekend plays host to is the fireworks show put on by your city or your drunken neighbors.

Roman candle wars aside, have you ever wondered what the 4th of July looked like from the fireworks’ point of view? We did, and so did [Jeremiah Warren], who put together an awesome video showing what really happens after you light the fuse and run away like a little girl.

The dizzying video was shot using a pair of key chain cameras that he strapped directly to the rockets before launching. It’s pretty entertaining, so be sure to check it out if you have a few minutes to spare.

This probably doesn’t quite fit the criteria to be considered a hack, but with explosions and the crazy point of view video, we had to pass it along.

Target hunting UAV armed with fireworks

Don’t just build a UAV, use it to blow things up. In this case a tri-copter seeks out colored balloons and pops them using low-grade fireworks. We’ve seen this type of flying armament before, but not in a ‘copter form factor. It looks like the targeting and firing is done by an operator, and is not an automated system despite what the text overlays on the video after the break says. The lack of autonomous firing capability makes this delightful, rather than scary. Don’t miss the build log for the tri-copter itself. How do you think this one stacks up to the last 3-bladed build?

UAV reigns down vengeance upon thee

An unemployed electrical engineer can be a very dangerous thing. [Cybrown] has turned his skills toward darker, more awesome applications by building an armed unmanned aerial vehicle. This is a remote control airplane that has a movable camera mounted in the cockpit. Video and GPS data are sent back to the pilot who views the picture via a wearable display. We’re betting this doesn’t have the range that the 100km UAV did, but that’s good because this one brings doom from the skies. Check the wings in the picture above, this RC is fireworks-enable. We’ve embedded flight footage and attack video after the break.

Update: Here is a forum post covering this nugget of awesome. There are just a few details but the entire thread is interesting. Someone pointed this out in the comments but they don’t get credit because they didn’t leave a link.

Firework ignitors and controllers roundup

fireworks ignitor

With the 4th of July around the corner, we thought it would be a good idea to give a controller wrap up and show you how to make some ignitors. Last year we covered a microcontroller based fireworks launcher. If you like the idea of a controller but don’t want to run all the wire, we have the wireless fireworks controller. Adding a little twist to the wireless scene are cell phone triggered fireworks. Maybe controllers are not your cup of tea, you could try to microwave your fireworks. After the break we show you how to make ignitors from a diode and a match.

Cell phone triggered fireworks

remote_trigger

[Mr. Hasselhoff] is using a disposable cell phone to trigger his fireworks. He has wired into the speaker leads for the speaker phone. When the phone rings, the current sets off a thyristor allowing for a battery pack to be discharged into a rocket fuse. These fuses heat up and ignite, so you can use them to light fireworks fuses pretty easily. This is pretty simple and cheap, considering the price of the cell phone was only $10. His next idea was to have it recognize dial tones and set individual fuses off, but that would require a microcontroller and a much more complex hack. At that point, you might as well just build a fully fledged wireless fireworks launching system and possibly add rocket launching abilities too.

Microcontroller fireworks launcher

After being inspired by our previous posts on a microcontroller-powered missile launcher and the wireless fireworks controller, [Adam] at Additronics.com decided to build his own microcontroller launcher. He combined elements from each of the prior projects, and included some of the advice from the Hack a Day comments. His multi-rocket/fireworks launcher is configured with an Arduino Diecimila, and requires a whole boatload of batteries. [Adam] claims there’ll be another video at New Year’s of the microcontroller in action, which we’re definitely looking forward to watching.
