Automated Shooting Range

targets

[Steve] was discussing airsoft with a friend when he came up with this idea. His friend was lamenting the lack of “action” style targets for their airsoft hobby. [Steve] took this as an opportunity to make his own automated target system. The targets themselves are made from Construx, a paper target and a piece of cloth to stop the airsoft pellets. Controlled by an Arduino and an ioBridge module, it has a web interface so he can switch programs from up range. You can see a video example of him shooting some targets after the break. Next,he should make it twitter where each target was hit.

Meggy Serial Cable

We thought the Meggy had some serious potential. The open serial port is ripe for the plucking, but has thus far been fairly unused. Here’s directions on how to make your own serial cable capable of connecting two Meggies. Basically, it is just modifying an audio cable, used to connect CDROMs to the motherboard. The cool thing about this is that the resulting crossover cable should work on any Arduino that is programmed via an FTDI cable.

CUIduino, Arduino With True USB Support

The CREATE USB Interface (CUI) was a project that came out of UC Santa Barbara around the same time the Arduino was being developed. It has a USB port, a PIC18F4550, and a prototyping area. It was designed to enable easy interfacing with the real would through many A/D inputs and general I/O ports. It supports both OSC and MIDI-over-USB natively. The biggest difference between the CUI and the Arduino is its USB support. The Arduino uses an FTDI chip to create a serial interface to its onboard AVR. The CUI’s PIC has native support for USB. That means you can have the CUI appear to be any USB HID device you want: keyboard, mouse, game controller, etc.

The Arduino has a friendly development environment and a large following though. CUI create [Dan Overholt] decided to add an ATmega168 to his board to get the best of both worlds, the CUIduino (scroll down). It can be programmed just like any other Arduino compatible device, but the having the CUI parent means your Arduino project can behave like a native USB HID gadget.

Illuminato

illuminato

[Matt] sent us this very cool looking project called Illuminato. After brainstorming on how to improve upon the Arduino, and receiving lots of input on his ideas, [Matt] has put together this board that has several nice improvements. It has more I/O, more code space, faster serial communication speeds, built in PWM, and works with existing Arduino shields. Not only does it make these improvements, but it does it with style. The finish is quite nice, the layout is pleasing and it even has two rows of SMD LEDs on the back for some added geek cred. You can see a couple videos of it in action after the break.

Autonomous Game Controllers

On the off chance that you want to program a microcontroller to play your games for you, you should check this out. Near Future Laboratories has made a dongle that can allow an Arduino to operate as a PS2 or PS3 controller. You can see the Arduino running a random path generator in Katamari Damacy in the video above. They wanted to see how long it would take to clear a room. It managed to get almost all of them in about 70 minutes, only missing those that you have to cross a narrow bridge for. Actually, this could be quite useful in allowing people to create alternative input methods. You may recall reading about their early progress back in June 2008.

RepRap Motherboard

When the RepRap team found themselves pushing the limits of the Arduino, they started looking for alternatives. They found it in the ATMega644P. It has four times the memory and four times the RAM compared to the ATMega168 used in the standard Arduino. It also has 32 I/O pins. They ported the Arduino software to the microcontroller and started producing Sanguino boards. Now that the base design is nailed down, they’ve begun expanding it to their specific purpose. Pictured above is a prototype RepRap motherboard. While the Sanguino is barebones, this board has onboard connectors for all of the RepRap’s motors, so you can just plug it in. It is also designed to support the future Generation 3 electronics. Probably the most interesting feature is the SD card slot. The goal is to eventually have a board that can run the RepRap without a host computer if necessary; it will manufacture designs directly from the flash card.
