| jaugustine@verizon.net: Apr 10 08:25AM > UPDATE: > Thanks to you, I just ordered the cable from notebookcables.... > Regards, John WARNING/CAUTION: I received the cable in the mail late yesterday. This "extension" cable is DEFECTIVE. The connectors are "out of phase". The top row of pin connectors on the female side are connected to the bottom row of pin connectors on the male side, and vise versa. Note: If you "flip" the 2.5 inch hard drive, Pin #1 will end up connecting to Pin #20, etc. This cable came from Atlantic ComputerTech, 95 Horton Ave., Lynbrook, NY 11563. I will call them after 8AM (now 7:25AM) about returning this cable for a refund. I am afraid that all their cables may have the same problem. If I have a problem getting a refund, I will report back.

I think if you used two of them for a total of three flat cables connected together, it may work. You don't want exceed a total length of 18" as that would exceed the specification, so keep that in mind as well. http://en.wikipedia.org/wiki/Parallel_ATA |

Hi, I called Atlantic ComputerTech, and I had no problems regarding making a return for refund or exchange. It turns out there is a "true extension" version. Until now, I did not know that there are two types of extensions. CAUTION: If you want a "true extension", the top pins on the female connector are the top pins on the male connector, order FI2-X06M.

I did not know there are two types of extensions until now. John |
| Cursitor Doom <curd@notformail.com>: Apr 09 06:02PM Hi all, I've got two 240VAC/240VAC 500VA isolation transformers. Before I sell one off I thought I'd best check whether there are any circumstances in electronic repair when it's really handy to actually have two of them and/ or can they be hooked up together to provide 1KVA supply? thanks, cd. |

To check this, with both trannys connected to the AC supply, link the secondary wingings at one end and measure the voltage across the remaining wires. It should be either 480V or close to 0. Reverse the connection if it is 480. Close to 0 = about 0.5V max. To safely parallel the pair, the primaries must be wired to the SAME AC plug - cos using two plugs means one will have exposed live pins. ... Phil |

Maybe a sandwich of blue glass and 2 slabs of white glass, not equal > thicknesses It's the IR blocking filter, and usually also a pair of crossed walkoff plates that spreads the light out evenly over the 2x2 pixel subarray (2 green, 1 red, 1 blue) that corresponds to each display pixel. That prevents coloured jaggies in the image. The colour filters used in CMOS and CCD processes are organic dyes, which have a huge hole in the NIR. You need a separate IR filter, or the colour balance will be all off and you'll start seeing through some types of clothing. (There was a bit of a flap some years ago when Sony introduced a camcorder that did that.)
