If you’re making a GPS-enabled project, you may have noticed the commonly available GPS modules are pretty expensive – usually around $50. Here’s one for $8. It’s a U-blox PCI-5S GPS receiver on a PCI Express card. There are test points for serial and USB data, though, so fitting this in your project is a breeze.… Read the rest
This open source sentry gun controller board builds on a great concept by getting rid of the Arduino board. The previous version was an Arduino shield, but this upgrade keeps all of the cool features by rolling the necessary parts into one smaller footprint.
The image above doesn’t quite convey the scope of the project. Go take a look at … Read the rest
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 system works by preloading a … Read the rest
What is the best thing about making a computer program that targets and kills anything that enters its sight? Why giving it a weapon, of course! No, we are not talking for real, but the next best thing, an Autonomous Paintball Sentry Gun.
The autonomous part of the device comes from a pc on the sideline and is fed … Read the rest
[Patman2700] has a nice scope for his paintball gun that uses a red dot instead of cross-hairs. The problem is that he kept forgetting to turn it off which ended up running the batteries down frequently. His solution to the problem was to get rid of the toggle switch used to turn it on and replace it will a home-made … Read the rest
If you’re too frail to take the full impact of a paintball round let this tank serve as your surrogate. The camera perched on top of the platform feeds video back to the operator’s head-mounted display. Instead of using a joystick or other traditional controller, the user aims by looking around, with his or her head movements mimicked by the … Read the rest
PVC hull, SLA batteries, Bilge Pumps, sounds like a good start to [Jimmy's] ROV project. Paintball gun (as a BCD), dual live cameras paired with an Arduino making it internet controlled, all tethered with a fiber optic cable, sounds like [Jimmy's] ROV got a whole lot more astounding.
While some very important parts have yet to be implemented, like … Read the rest
