dganapa writes "Researchers at the California Institute of Technology, headed by Dr. Ali Hajimiri, have developed a low-cost radar system on a silicon chip. The entire system has been designed from the ground up on silicon, thus leading to reduced cost as well as robustness in response to design variations and changes in environment. The chip runs at a staggering speed of24 GHz (enabling it to transfer data as fast as the main network of the Internet) and can soon lift wireless, high-frequency communication to a whole new level. The radar as such is not as powerful as a conventional radar but because of its cost-effectiveness, a number of them can be coupled together to perform really well. A related NY Times article is here. A recent article from Slashdot shows that radar technology is increasingly being implemented in the automobile industry. This current chip is sure to be much more successful than its predecessors as far as the automobile industry is concerned, but whether or not its processing speed will become important in the computer industry remains to be seen."

hacker asks: "I have been asked many times over the past few years to support "web-based calendaring" with pilot-link, so people can syncronize their PalmOS handheld devices directly with 'online' calendaring software. The problem is...what calendaring software? I've looked at the various alternatives (PHP iCalendar, WebCal, and about two-dozen others) free and commercial, and none of them really offer a good, powerful, flexible way to integrate the same kind of data that resides on a Palm handheld device. I would write the conduit between Palm and calendaring software. Has anyone actually used a web-based calendaring product they like, and if so, which one, and why? Would the ability to syncronize your Palm handheld with your web-based calendaring software be useful?"

mbathgate asks: "In the world of residential academia, cell phone proliferation is so immense that at many schools they've pulled the plug on landline long distance service, including mine. I have a cell phone, but I can't fax through it, and dialing 29 digits for every fax is a real pain (few faxes are local, especially in Los Angeles). I need a finger-saving solution, but I don't want a web or email-based service, for a number of different reasons, mostly legal and security-related (please save me the flaming - the decision is made). VoIP looks very attractive to me, though, with a 100baseTX port in my room connected to a huge pipe. Slashdot has covered switching to VoIP before, but the focus has been mostly voice calls. I've hunted around on a few different sites, but haven't come across anything which assures me that VoIP would work for my situation. I need a solution for high quality outgoing calls to landlines which can connect to my existing fax machine (RJ11 port). It must be Mac OS X compatible or OS-independent. An incoming number would be nice, since it would let me receive faxes without being there to manually press 'Receive', but considering our anal-retentive firewall policies, getting it to work outgoing would be a good start. Does Slashdot have some experience with faxing via VoIP that they'd like to share?"

fgodfrey asks: "Being a computer geek during the day and a theater geek at night, I'm looking to combine the two and turn a non-Windows computer into a theater lighting console. All the products out there that I've seen (such as Martin's 'Light Jockey' and Rosco's 'Horizon') only seem to support Windows. I'm looking for a solution that works on Linux, or preferably, Mac OS X. It also would require a DMX converter (DMX being the standard in dimmer control protocols) that could plug into the computer. I'm looking to be able to run an entire theater show directly from the computer. Has anyone out there tried such a thing? Before anyone suggests X10, it is not really acceptable for theater lighting as it doesn't respond 'instantly' to commands and would require a ton of X10 boxes."

Missionary Man asks: "I'm an electronics teacher looking for a good (but reasonably cheap) PC based oscilloscope for classroom demonstration purposes. I've done a reasonable amount of research and come up with a few contenders. Ideally I'd like something with a bandwidth of up to 40MHz and 2 channels. Does anyone have any tales to tell regarding the use of any of these scopes (or any others I haven't found or mentioned) and can recommend a suitable device?"

demosi asks: "I'm involved in the NOMAD project, which is described here. Part of the work involves determining how community wireless services can be best used to build social capital (i.e. whether something will have a positive affect on the productivity of a community and its members), by promoting communication in a trustworthy environment. We're asking Slashdot readers if they're involved in similiar projects and if they're interested in measuring the network effects of community WiFi across different countries and cultures?"

eggoeater writes "Forbes Magazine has an article discussing how more portable electronics are not only suggesting firmware upgrades, but requiring them in order to get all the features! Apparently the new Lyra A/V Jukebox will sometimes display a message stating that 'this feature will be available in future upgrades.' In addition, the article states that some patches are difficult and dangerous depending on the component. Some cell phone patches require a proprietary cable ($25) that will then wipe out your phone book. This raises concerns over alienating users that aren't tech-savvy and how this could affect perceptions of portable electronics as a whole."

broKenfoLd writes "Monkeys moving robotic arms by manipulating a cursor on a computer screen, simply by thinking about it? Mice who cause their water tube to dispense some refreshing H2O just by wishing it? Signal processing and decoding has long been a dream of Matrix fans and lazy system administrators for years, and science is amazingly keeping up! Popular Science's Carl Zimmer has written a fascinating piece documenting recent progress in decoding brain signals and interpreting commands issued from thoughts alone. If you heard a single violin playing Beethoven's 5th, you would be able to tell what piece of music was being played even though the rest of the orchestra was not heard. In the same way, by monitoring a relatively few neurons, computers can recognize patterns and allow programming based on these patterns to say, know if a mouse is thinking about pushing his water lever. You can pass the time waiting for Matrix-style video games and motionless system adminstration/utilization by reading the full article."

Steelduck writes "A person nick-named Xor'Arch at the CaseJunkies forums has made an uber-cool case mod. A Borg cube based on a Via EPIA-M platform. The project took them 9 months, in which they spent 250 hours of their spare time. In total, they used about 60 meters of steel wire, and 1,5 m2 cardboard.The Borg Cube is presented at Casejunkies website. http://www.casejunkies.com/index.php?upn=010001&hl _id=1873"

Chasuk asks: "I work at a large computer retailer in a college town, and I've finally convinced the powers-that-be to sell PCs with Linux pre-installed. The catch is, it will only be installed on Micro ATX machines, which require half-height everything, and we can't find a source of half-height Linux compatible PCI modems. Even those universal, generic half-height replacement hangers/brackets would be acceptable, but I can't find those, either. Can anyone on Slashdot help? "

djhanson wonders: "I just got back from a small claims court proceeding against Apple Computer. They successfully won their argument in front of the court that selecting additional memory and disk drives for a computer/server at the time of purchase, off of their website, constitutes a 'custom configured computer built to the customer's specifications'. Said computer is therefore not eligible under the company policy to be returned. Has anyone else heard of such a thing? As near as I can tell, Apple is the only company that has such a restrictive policy. I called both IBM and HP, and neither of those companies has such a policy. Am I the only one that thinks there is something terribly wrong with a policy like this? Any opinions? Suggestions? Comments? Whatever?"

travik asks: "I use a Nokia 3650. The cell phone already knows my co-ordinates (E911 service). It has Bluetooth. Why can't I send the coordinates using Bluetooth to my laptop, and use a mapping application to give me my location and directions to where i want to go. I've searched Google and also read up on old posts, no one seems to be doing it. Why?"

PHPee (Rob Maeder) writes "Scott Fullam's Hardware Hacking Projects for Geeks is an excellent book outlining all you need to know to get started in the wonderful world of hardware hacking. With step-by-step guides to fifteen useful, amusing and off the wall projects, even a novice hacker can be up and running with some basic hacks in a few hours. The book demonstrates various ways consumer electronics can be modified to do things they were never intended to do, and shows you just how much fun voiding your warranty can be." (We mentioned this book yesterday, too.) Read on for PHPee's review.

EvilJoven asks: "About a month ago I spent quite a large chunk of change on a new system only to have my cat chew through the VGA source cable of my brand new display. Over the course of the last few years my cat has cost me nearly $300CDN in repair and replacement costs due to chewed cables including a few power cables which are not only a pain to replace but potentially fatal to the animal and a fire hazard. So far the best solution I've found to stop this is wrapping all my cables in Snap-On Wire Protectors (about $6CDN for 3m at Canadian Tire in the Automotive section) but this is a rather unsightly solution. Due to the fact that I live in a one bedroom apartment restricting my cats access to my hardware is not an option. I was wondering if anyone has any suggestions on a better way to protect gear from animals."

Shibatch writes "Hitachi, Ltd has developed a 3D display called Transpost which can be viewed from any direction without wearing special glasses. 3D movies can be seen as floating in the display. Also, 3D movies captured at other places can be shown on the display in realtime. The principle of the device is that 2D images of an object taken from 24 different directions are projected to a special rotating screen. They also developed a camera which can capture images from 24 directions simultaneously." The pictures are interesting, but ... translations, anyone?

Thanks to GameSpot for its article discussing the latest Japanese arcade games showcased at the AOU 2004 show in Tokyo, with a particular highlight, as well as an example of building a play experience unique to an arcade, being Sega's Quiz Show, which "gives the player the experience of being a contestant on an American TV quiz show." The Japanese page for the game has pictures of the massive arcade cabinet, which has players "sitting behind a colorful table, just like a real quiz show", and allows each contestant to answer trivia questions which are "randomly selected by a physical, spinning wheel that's attached to the game booth."

Viqsi asks: "Back in my Win32 days, I was a very frequent user of RAR archives. I've had them get hit by partial hardware failures and still be recoverable, so I've always liked them, but they're completely non-Free, and the mini-RMS in my brain tells me this could be a problem for long-term archival. The closest free equivalent I can find is .tar.bz2, and while bzip2 has some recovery ability, tar is (as far as I have ever been able to tell) incapable of recovering anything past the damaged point, which is unacceptable for my purposes. I've recently had to pick up a copy of RAR for Linux to dig into one of those old archives, so this question's come back up for me again, and I still haven't found anything. Does anyone know of a file archive type that can recover from this kind of damage?"
