Fresh hacks every day
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 … [Read more...]
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 … [Read more...]
[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 … [Read more...]
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, … [Read more...]
Today is the Fourth of July in the US, where we celebrate our freedom by blowing up a small portion of our country. Embedded above is [Jory] and [Jonathan] doing it wrong by microwaving their fireworks. We think a good formula for this year's celebration is wireless fireworks control, gas powered blenders, and CHDK's motion sensing to get the perfect firework photo... and if we get really bored … [Read more...]
[Tuckie] sent in his wireless fireworks controller. The electronic parts are off the shelf - a 12 channel relay board and remote provide the guts. He used a rock tumbler to mill the black powder needed to make the detonators. A combination of the fine ground black powder, nichrome wire and ping pong balls makes up the business end of each detonator. When a channel is selected with the remote, the … [Read more...]
