Here is a good website that I used to build an antenna one afternoon: http://uhfhdtvantenna.blogspot.com/
I currently live in Palm Bay, about an hour away from Orlando on the East Coast of Florida. If I point this antenna toward Orlando, I'm getting around 25 channels that come in solid using a Tivo HD. We love it and it only costs $13 a month for the Tivo service.
This post is in response to the current worry by media giants about copy protection.
I've often thought for hours upon end about the effect of media upon people and their eventual response. Think about a time when people can get all the bandwidth they want anywhere and anytime. First there will be a huge fad swing, then after some indeterminate time, there will be what I call the "fallout". In my own personal experience, why would I want to record anything, when I can have clear digital radio pumping thru my ears. Eventually the people of the world will awaken to their more base instinct to be lazy and not care about all the data hording that we are seeing in the present age. Data hording just creates more headaches! It just creates more work for you when you think about it. You also have to spend more money to buy more storage. This fact will eventually catch up will the fads that are spawned with each upgrade in our infrastructures.
I was able to read the pdf on the rail gun. The concept sounds neat, but the pdf article didn't exactly address the electric generation problem of a rapid fire system. The article claims that it takes the same energy to deliver 6 round per minute as it does to run the ships propulsion system. Have we even solved that problem yet? I don't think the overall cost of developing the power generation was really highlighted in the rail gun pdf. I can really believe you can save that much money if you have to generate all of the weapon's destructive power every time you fire it.
This is a neat idea, but please be aware of semiconductor physics before getting overly excited about it's capabilities. You can't communicate seamlessy across the whole electromagnetic spectrum with any device that's affordable. That's why they mention "broadband" on the website. Most of the time when you gain flexibility, you also bring on a butt load of tradeoffs like more power consumption and poor performance. It is a really good idea, though. Hope it takes off!
He should have gone to the teacher like he was told. The real problem is that there was a schedule issue with availablility of TAs or teachers. It seems like the way the Georgia Tech found out the problem was through lines of similar code. This is an obvious infraction of the rules and he should have gone and attacked the real problem - lack of available teachers/TAs to help him.
It seems like this is a very damaging article to the name of Georgia Tech. As a Georgia Tech alumni, I am aware that there are some scheduling/availability problems on campus sometimes. I think this should be the crux of the problem. I think that the Washington Post article was crafted a little bitterly for some reason or another. I'm sure it got the attention of many readers - keep in mind, that's how the Post puts its bread on the table.
Although I'm not an expert in electronics, I'm an RF/analog engineer and have noticed a few trends. Researchers invent a technology that is great and then someone gets on a bandwagon to have the technology solve many more problems in a shorter amount of time than ever actually happens.
MEMs in an outstanding idea, but in order to have a cell phone on a ring, you are forgetting all of the other components. Are these magically going to morph into smaller spaces and perform? Also, talk to a packaging and/or manufacturing engineer and figure out how easy his job is going to be:) You can't just scale down and expect the laws of physics to follow suit. Try to fit a battery on that ring and have it transmit to a base station that's a mile away. If you've got 50% effeciency on the power amp, then your finger is taking 50% of the transmission power as heat. I guess you could have a liquid cooled ring:)
I dream that this technology will help us get there, but I wouldn't hold your breath for a ring cellphone. They've already got a cell phone that transmits from a wristwatch, but this device has a huge problem with the battery.
Actually, I would like to see what effect the new fuel cell technology with make upon the market.
I would encourage any of you who are interested in RF/analog engineering, electronics packaging or electronics manufacturing to consider the huge opportunities that exist for you today. It is a challenging but very rewarding job for those who are interested.
