Today, Comcast updated their Acceptable Use Policy to cover exactly what they feel is "excessive use". Starting October 1st, they will contact people breaking the 250GB per month transfer limit and ask them to curb their usage. While it'll be hard for most people to hit this limit, we still wonder if policing 0.1% of the customer base is worth the effort. At least Comcast has bothered to state the limit instead of just secretly rewriting the meaning of the word "unlimited" like some providers.
This is another fine project to come out of the benheck forums. [sam_thornley] built this portable game system last Fall. It uses the guts of a JAKKS Namco TV arcade stick. The composite signal from the board is connected to a 2.5" Intec screen with a CCFL backlight. Four rechargable AA batteries are in the case for 2.5 hours of play. It doesn't have sound, but he says the TV games' sound pales to the original anyway. It's certainly a nice compact build in a regular project box.
During the last day the web has been abuzz about Mozilla Labs' Ubiquity. It's an addon for Firefox that can help you streamline how you get things done on the web. In the example above, they show constructing an email with a map and reviews using mostly keyboard driven input. The addon is quick to install and we think you'll find it saving you a lot of time on tasks you'd normally hit the search box for. In the popup, you can do quick Wikipedia lookups, define words, translate, perform calculations, and many other operations. You can email a page to someone by just typing three words. The best part is: anyone can write a command that will expand Ubiquity's function. Greasemonkey helped fix broken websites and we think Ubiquity will help make interactions between sites much easier. We can't wait to see what clever uses people come up with.
Reader [Kelly Regan] flies large scale RC planes, but would often need someone call out flight sequences while rehearsing. Not wanting to impose on fellow club members, [Kelly] built a sequencer caller from a cheap MP3 player. It just required extending the FWD key to a pin header. Those pins are connected to a custom switch on the back of the controller. Each maneuver is recorded with 30 seconds of padding and then added to a playlist. Once the maneuver is complete, a quick press of the button moves on to the next track. It's always nice to see people building devices that the consumer electronics industry probably wouldn't.
OpenStomp's Coyote-1 is now available for $349. The guitar effects pedal lets users design and upload their own effects to the device. It has two stomp switches with LEDs, an LCD display, and four user assignable knobs. The back has 1/4" in/out and one selectable 1/4". It also features NTSC composite out, a headphone jack, mini-USB for uploading, and an RJ11 I2C bus for expansion. The processor is a Parallax Propeller Chip. While the OS on the pedal is open source, the hardware design and effect design software are not. You can check out the source and product manual on their forum. If you're more interested in breadboarding hardware, you might like the Beavis Board we covered earlier.
It's no secret that we're gear heads at heart. Our transportation hacks category is full of unfortunate machinery like [Steven Laurie]'s motor art, weed whacker bikes, and electric motorcycles of all types. Even we have trouble justifying the existence of this monster truck style lawn tractor though. We haven't found a project site for it and can't help but wonder what kind of person would build such a thing? It's obviously the type that would own a car sized American flag. We just need to realize with the popularity of lawn mower racing, this sort of thing was bound to happen.
Graffiti Research Lab's [James Powderly] along with 9 other Tibet supporters were deported from China during the Olympic's closing ceremonies. Detained on the 19th, the activists were to serve a 10 day sentence, but the Chinese government buckled under international pressure and deported them early. This brings the total number of deported activists to 53 since the start of the games.
[Manuel] has been playing around with [Johnny Lee]'s Wiimote head tracking code. He's posted a preliminary port outlining the code in the Processing environment. It relies on darwiinremoteOSC so you won't see this outside of OSX, but it should help you out if you're trying to do this is in Processing on another platform.
SparkFun's new Arduino Pro is an updated version of their Skinny. The board comes populated with the running gear of an Arduino, but without all of the connectors in place. It's targeted at people building integrated systems around the Arduino and not just prototyping. The board is 3.3V with an 8MHz bootloader just like the LilyPads and is fully certified by Arduino. It has a small side mounted power switch, but you have to supply your own DC jack (if you need it). There is no USB hardware on board and you're expected to program it via an FTDI breakout board or cable. We definitely like the stripped down approach, but it would have been nice if the price had dropped more.
We announced the Hack a Day t-shirt design contest last week and entries have been rolling in. Check out the updated contest post for logo images and the font. Here are couple of the entries we've received:
Here's an interesting kit put together just to help you work on your SMD soldering skills. It's got 49 SMD LEDs on the front with a programming header and switch jumper. The back has an ATtiny26L and a coin cell. At only 3V, power management is essential; all of the example programs are only addressing one LED at a time (imperceptible to the human eye). If you turn on too many LEDs at the same time, the voltage drop could cause the AVR to reset. Included example programs are a scrolling marque, bouncing balls, and Conway's game of life. SparkFun has tutorials for regular SMD soldering and using a reflow skillet. The video below shows the kit builder attaching just one LED using the heat and slide method.
Taking a cue from the jog wheel we posted last week, [42ndOddity] has built an improved version. The design is based around a solid state rotary encoder instead of an optical encoder. The rotary encoder is far easier to attach and position properly. The knob is milled from scrap aluminum-it was a copier foot. To make the motion smooth, it's sitting in a bearing from the same copier.
[Cory Wright] shares a tip on how to reboot a system with a failed hard drive remotely. The magic SysRq key is a linux kernel feature that lets you perform a number of interesting operations. If you're working on a remote system where the disk has failed, you won't have access to the reboot or shutdown commands. You can issue keystrokes to the magic SysRq device in /proc though, so you can send a hard reboot directly to the kernel with no disk access required.
The Wikipedia entry includes a handy tip on how to properly restart a otherwise frozen machine. It should save you from having to fsck the next time around.
