    Stand alone players read the header on a blank CD to get information such as what size it is, who made it, what type of die is used, etc. This format information is written and pressed in from the master. It is not alterable as it is pressed not written from the master. Consumer computer CDR's may ignore the Music CD bits. A hardware deveice may have have coding to not ignore these bits and refuse to write to a non-music CD.

    It does come with a 10/100 ethernet port. But it looks like it is only used with it's web browser for broadband access thru your supplied router. They are tight lipped about what format you can post your music online. We need a good review of this in action on getting and putting MP3's to and from this device. We also need a positive answer. Will it burn MP3's on a CDR as MP3's and not a music CD? In other words.. Can it export the MP3's?

    Hmmm, In that case, I'll hold out for one with an ethernet port instead of a modem. I want the ability to upload/download with my high speed connection and FTP to this device. That way I can also burn the MP3's into a CDR. The website says you can burn your favorite music to CD's. Reading between the lines means a music CD, NOT A MP3 CD!. You won't be getting MP3's off this to share with friends.

    Yes I geocache. Just for fun, I have hidden a cache in a Hide A Key box. I have had more than 20 people find it so far. The location given is close enough they can identify what structure in the park it's hidden in, on, or under. Comments about wanting to tear it apart to find the cache are common. Use keyword "Tiny" if you want to look it up on the website. It is not uncommon for a cache to be found 50 or more feet from the posted location, but many finders post the error seen and other cachers get the same results. Caches on mountain ridges with a good WAAS signal typicaly are found with 10 feet. There is no question which tree, brush, or rock outcropping it's hidden under. Signals in heavy forest on the side of a hill or ravine are more of a job to find.

    Some high end pro audio gear also uses heat pipes to large heat sinks. Getting the geometry right to sit on a socketed CPU is probably why they are not used. Big 3 lead transistors can simply be bolted to a copper block on the heat pipe. I've also seen convection oil cooled equipment.

    Anybody that uses a meter should be aware of that. To make it simple, on most TV's the yoke unplugs. Anyone not knowing where the yoke is, or what it is should not attempt this. Most of the HV stuff is on the second anode. It is supposed to bleed off (by a resistor) but don't trust it. It does fail once in a while. The regular B+ usualy disapates quite quickly unless the set is broken.

    Warning! A set that does not come on is the set most likely to have stored power as the set is not drawing it from the power supply. Do not assume a dead set has no power. Check it with a meter and discharge the capacitors.

    I first saw them ad figured this is a mistake. I contacted Radio Shack and Symbol regarding the limited usefullness of the product. I let Digital Convergance know I already had a bar code scanner. What would be wrong with putting the URL in things with a regular extended 3 of 9 barcode? Wouldn't more people connect and use the scanner if they could also be used for other things? If my mouse could be used on one web page and not for any other program like word processing and spreadsheets, I probably wouldn't have a mouse connected. The same thing applies to a single puropse bar code scanner. They got greedy and wanted every scan to belong to them. It backfired as nobody had a reason to connect them. Giving out scanners and having a website with good content linked to the media may have been useful. (scan your coupon here, or scan for a rebate here) Magazines could serial number coupons in a magazine and this may increase magazine sales if you needed to scan a magazine to get an offer listed on a website. The Radio Shack catalog was a good use of the technology, but it was incompatible with my laser scanner. I didn't want to connect another harder to use scanner just to use the catalog. Online orders could have been easy. View more details by scanning the catalog (done). Fill out order by scanning in needed items (missed). Fill out your shipping info by scanning your shipping label (missed). Typos could have been eliminated from online ordering, but due to the DC software, this type of activity could not be done. All scans wanted to launch a new browser window, or take your browser to another web page. It could not be used to fill out an online form.

  11. A small correction from the industry... on Building Cheap 100 Inch TVs · · Score: 2

    Colored filters? Never seen one. If you buy a set of projector CRT's (visit a repair shop and ask to see a set of used ones) it is about impossible to tell the colors apart. They all have a yellow whitish phosphor and no filter. To keep from blocking the light produced, they use a phosphor that only produces the color of light needed. No filter = no blocked light = brighter image. If you don't have access to a projector tube set, use a good magnifing glass and look at the screen of your TV when it is off. Can you tell the difference between the red, green and blue phosphors? I can't.

  12. Re:Did this years ago on Building Cheap 100 Inch TVs · · Score: 2

    For those most inclined to try it... The red and blue wires to the yoke are usualy the horizontal. The green and yellow are the vert. Never turn on a tv without the yoke connected. It is usualy instant death to the horizontal section and a burned spot in the center of the CRT. Use a meter to verify wire pairs. Reverse the leads on both pairs. One pair turns the immage upside down and the other flips it right to left. Due to the location of the high voltage lead on the top of the CRT, just turning the CRT upside down in the set is not a good idea. The CRT connector usualy will not fit after the tube is turned upside down.

  14. The real reason the color distorts... on Building Cheap 100 Inch TVs · · Score: 2

    It is related to gravity.. The picture tube has a shadow mask. It is thin. It sags slightly (affected by gravity). It is true the beam is affected by the earth's magnetic field, but distortions to the shadow mask are a bigger influence. Try this at home... turn a large TV around and notice the color shift. This color shift is due to reversing the earth's magnetic field 180 degrees. Now lay the set on it's side or upside down. This color shift is due to both gravity and magnetic field. Notice how much greater this shift is. Only a small portion of the shift is due to the earth's magnetic field. The magnetic field was most noticable on large computer monitors that has a fine dot pitch as the small shift could more easly misallign the beam to the phosphor. Most TV's have large pitch so the magnetic field has a smaller effect on color purity.

  15. Re:Reason for lack of brightness on Building Cheap 100 Inch TVs · · Score: 5, Interesting
    For anybody who wants to know why they are so dim..

    A CRT projector of the 3 tube variety uses this setup for several reasons related to brightness. Number one on the list is no slot mask! Each tube is one color. You are not blocking 80% of the electron beam to the phosphor with a matrix shadow mask inside the CRT.

    Number 2 on the list is F stop. A large CRT giving off light with a lens far away gets very little light to and thru the lens. Most (about 80% or more) of the light hits the inside of the box instead of the lens. A projector set uses a small set of CRT's so the lens is very close to the CRT getting most of the light thru the lens. The smaller CRT's can easly have flat faces taking care of the focal plane problem also.

    Raw Power.. The small CRT's in a projection set are not limited in beam current as there is no shadow mask to worry about overheating. The face of the CRT is gel or liquid coupled to the lense to reduce interelement reflections and aid in cooling. They can put out brightnesses on the face of the CRT's that can be painful to look at unlike a conventional tube.

    The last item is when the distance to a projection surface doubles, the brightness goes down with the square of the distance. Doubling the distance to double the size decreases the brightness 4 fold. This is true for both a real projector and the home made variety, but the home made doesn't have the brightness to sacrifice on the larger immage.

    With all these factors working for a 3 tube projector and against a single tube, the diffrence in projected brightness is typicaly more than 200X brighter. Translation.. a room with a couple candles in it will typicaly wash out the image on the home made projectors.

    Humor aside, it's the same reason your car has a battery. It is not there to keep the lights on when the car is parked, but to provide high power (starting) for short amounts of time. The shoes may generate a half watt. Some mobile phones run on 2 watts. The other 1-1/2 watts come from the battery while talking on the phone.

    An example I like to show, non grocery related, is ink jet ink. My old printer (HP722) used color cartridges that were 30 mL of ink.(HP C1823D) I bought them in the two pack for about $45. My new printer uses a standard cartridge that is 19 mL for $32.00 The high capacity cartridge is 38 mL for $53.00 for a savings of over $10 over two standard cartridges.(HP 78 A & D)

    I quickly saw the large capacity cartridge had only 8 mL more ink than my old printer cartridge at more than double the price. The big price change over my older printer rang an alarm bell, so I bought bulk color ink at 13.95 per 1/2 pint.

    I only buy a cartridge when one plugs up beyond revovery. I retained my old printer for printing web pages and other non critical stuff and use the new printer only for digital photography. My prints are often mistaken for conventional photos.
