Thanks for taking the time to drive a stake through this "vampire's heart". It was a fun review to read your page and I only had one comment: When you mention the zero group delay filter, are you presuming that he's not using that "hyperspace antenna" which was patented earlier this year? I'm still waiting to see if that inventor in Colorado is going to strike it rich with his "invention" or if we'll know he's on to something when the aliens show up at his house!! 73's Gary N8DMT
This is a great excuse for having some fun with Micro$oft. Try calling up their 800 number (free call for you, but not for them) and complaining about someone Hard Disk Loading a copy of Micro$oft Linux. "Honest! I saw them load your Microsoft Linux disk into three machines and they installed the same software on all three of them!" "But Micro$oft doesn't make Linux? I'm sure that's what I saw... Micro$oft Linux! L - I - N - U - X. Linux. Don't you know about Linux? I'm sure it was Micro$oft Linux. It even had the flying flag startup screen!" See how long you can keep them on the phone (remember: their dime, not yours) and pretend you're just a typical Micro$oft user trying to help them out. You can go a long way with this! Call 1-800-RU-LEGIT today to report your observed misuse of the Micro$oft Linux disk today! Call 1-800-785-3448 TODAY!!
Just be sure that your monitor offers synch-on-green capability before using the vga to 13w3 adaptors. Many multi-synch monitors today support synch-on-green capability. Cheapie monitors won't work with your SUN machine.
Given some experience in electronic product cost estimating, I believe you're a little high in your $20 number. Here's my estimated breakdown:
1. Reader wand (plastic $.05, reader source illuminator $.02, reader receiver $.10, processor IC $.35, cord & plug $.25). Unit total: $.75 for raw material. Call it $1.00 assembled & tested.
2. Packing material, manual & license docs, CD. $.35
3. Postage, 3rd class or lower. $.35 (??)
So the total is about $1.70 delivered to the target consumer. Now compare this to the value of the information. Very interesting...
It's clear to me (a seasoned electrical engineer with 15 years of RF/EMC experience) that this author has too much time on his hands and is now about to waste the reader's time too. If the concern is EMI getting into the RAM chip (and slowing it down or screwing it up), then yes, a bit of a shield might do something (however minor). But, don't forget that these shields work both ways! If the traces on the boards and/or the IC leadframes themselves are radiating due to changing logic states (quickly!), then how do you think they will react to having that signal travel the short distance to the shield, and then being reflected back to the source? Adding signals together with a short time delay (travel time to the shield and back) is always messy and sometimes creates signal cancelation--which is not good!. Given the distance between the sources and the receptors, I'd say this chap is chasing the wrong idea. If he's worried about signals getting into his RAM and slowing it down, then better to have a good metal case on his unit and--if he's really concerned about signal reflections--perhaps adding a little carbon based RF absorber lining the inside of the case. I for one, don't want to start reflecting signals from my computer parts directly back into them by putting close spaced shields around the individual parts. The RAM boards were not designed with this in mind and most certainly have not been tested to operate in this fashion. So play all you want with your individual computer system, but please educate yourself before advising others that "This is a good thing. Try it." From my perspective, you're doing more damage than good to this community.
...to get that kid who lives in my basement to pull back from that hyper-networked super computer and maybe go out and get a job! Here, Kid! Solve this puzzle and maybe someone will offer you money for sitting in front of THEIR computers!
This is just another case of being able to do something and thus considering actually doing it. Considering that the use will need to pay for the cellular airtime (GSM in the case for the Brits) means that the business case for this actually being implimented will fail! Can you imagine the government saying to you that you'll need to pay an extra $5-20 per month just so your vehicle can comply with speed limits? (Imagine how much fun it would be to "enter some data base values" which caused drivers to have to drive at 5 mph on the expreesway??) >

This needs to be moderated up!!

I don't think they liked my 'sig'...
Very Cool, but OUCH!!! $$$$

This will be found on many corporate printers before the end of the day...
