Internet controlled remote

How often does this happen to you? You’re leaving on a long trip, and half way there you remember the TV was left on. Never? Alright then, how about wanting to control an Xbox 360 from within the other room and you don’t have the remote. Still a rare occurrence?

Perhaps you have a better situation where an internet controlled IR remote, that can be programmed to work with any TV or IR accepting device, would be useful. [Nicholas McClanahan] starts off with USB Propeller from Parallax, adds an Ethernet module making a mini server, and ends with an IR LED and receiver. The code is nearly as simple being a combination of SPIN, Html, and JavaScript. All coming together under a nice website GUI that prompts for what IR signals to send. To make the project even more straightforward, [Nicholas] has included an Instructable as well. In the end though, while the hack is great, we’re still trying to find a decent enough use. Video after the rift.

PVC pipe fittings just for building stuff

If you’ve used PVC as a building material in your projects you may have run into trouble finding a way to make three pipes joint at right angles to each other (like the corner of a box outline). That’s because there’s no need for that type of joint when plumbing, the intended purpose of the PVC pipes. But [John] tipped us off about FORMUFIT PVC Fittings designed for construction use instead of plumbing. There’s a lot of interesting options, such as the ninety degree connectors, rounded end caps for aesthetics, and end caps designed to receive casters. We also enjoyed seeing the T connector that slides onto a pipe and can function as a swivel. We haven’t tried them out ourselves, but we think they’d come in hand whether you’re building complicated moving structures or just making a desk.

PlayStation 3 exploit using a TI84 calculator

[Brandon Wilson] came up with a way to exploit the Play Station using a TI84 calculator. This uses the same PSGroove open source code that we looked at last week. That package was running on the Teensy, which is currently sold out (we’d guess because people want to run the exploit). There’s a video demonstration of this new trick after the break. The calculator connects via a USB A to USB mini-B cable which comes with the calculator and is also used to charge the PS3 controllers. Once the connection is made, launch the software on the calculator, power cycle the PS3, and turn it on with the familiar power-eject button presses. The only problem with the system is that the calculator needs to be connected every time you boot.

Augmented reality UAV controller

Controlling a long-range unmanned aerial vehicle is much easier if you have an augmented reality system like [Fabien Blanc-Paques] built. On board the aircraft you’ll find a sensor suite and camera, both transmitting data back to the operator. As the title of this post indicates, the display the operator sees is augmented with this data, including altitude, speed, and a variety of super-handy information. For instance, if you get disoriented during a flight there’s an arrow that points back to home. There’s also critical information like how many milliamp-hours have been used so that you can avoid running out of juice, and GPS data that can be used to locate a downed aircraft. Check out some flight video after the break.

Constructing a CO2 laser cutter

angler

[Owen] contacted us to show us his site dedicated to his CO2 laser cutter build. He spent about 2 years and roughly $15,000 putting it together, so this is not small build. The laser and optics alone were $9,000. This site isn’t necessarily meant to be a template to build your own, but he shares so much information that we would certainly suggest you read it before digging into a build. He does have some downloadables, like the tool paths and the emc2 configuration files as well as a copy of the entire website. Great job [Owen].
