• Before transistors were available, what tubes/valves were used for driving incandescent lamps?

    In the early days of computers, there were of course no transistors. There was at least one type of tube that was specifically designed to drive regular incandescent lamps. I suspect there were actually several types available. The one I really want to know about was used in a homemade color organ that was either a one-off or a project built from a magazine article. Many online searches have failed to turn up the type of which I personally saw and handled three samples, so I Will Not accept responses saying that there was no such thing. It was, in fact, listed in one tube manual that later disappeared --- and it was the Only one found with the listing. I think it was a 5000 series or 7000 series 4-digit type number.

  • Why would a laptop drop to a drastically lower data rate or completely disconnect from wifi every few minutes during active use?

    My HP Compaq NC6220 running XP Pro keeps popping up the box that says "Wireless connection is now connected" every few minutes. This never happened when it was new, and it has not been damaged.

  • What is the procedure for uploading a VLC Media Player video to YouTube?

    I made a video on VHS, copied it to a DVD, then stored it on the hard drive in my laptop (HP Compaq NC6220 running XP Pro). I don't remember how or why it became a VLC file, but it did. Now I need to know exactly how to transfer it to Youtube. I have a YouTube account and, so far, have successfully uploaded one video from Picasa.

    I have looked and looked and looked online, only to be thoroughly frustrated by the confusing mess of choices. Prices range from around $14 for what is certain to be a piece of unusable junk to almost as much as the laptop cost to begin with. Some 'authorities' say to buy only original batteries from the laptop's manufacturer. Nice idea, but I can't afford that... even $10 is a lot of money for me right now. My hard limit is $60 including all taxes and shipping. I don't want general-purpose links to sites -- I've seen all of them, and I'm sick of them. Please provide the name of the source, the exact item number, and the price. Don't suggest that I get a new laptop: There is no money available to pay for it.

    Uniden BC760XLT scanner radio, serial # 05002596, code ODIO. No options have ever been installed. This unit worked perfectly at an estate sale on July 23, 2005. I shut it off, packed it in its original box, and bought it. Later that day, I unpacked it, connected power (factory-original wall wart), and switched it on. To my great disappointment, the display lit up, but was absolutely blank. There were no apparent results from pressing any button. The only controls that work are volume and squelch: The unit seems to be capable of receiving signals (it does receive band noise) and can be quieted, but it won't change frequency (not that one can tell without visible characters in the display). Checked lithium backup cell: Measured 3.3V in circuit. 8V regulator seems OK: Measured 7.8V across functioning display lamp. A technician at Universal Radio suggested resetting the unit by holding 2, 9, and MAN while switching power on. I tried that; it made no difference whatsoever. All evidence points to the conclusion that the firmware has been lost, but since there are other possibilities, one must keep trying. That's why this question is being posted. I don't have a service manual. Looking for one has proved futile. The company doesn't service any model over a certain age, and this one is far past that point, so forget that idea. SO: What failed, and what can be done about it? >> Based on my experience and the remarks of others, I believe I've figured out the reason for the name Uniden: If it doesn't work, "U NEED EN" new one.

  • What is your experience, good or bad, with the Kenwood TH-K2AT amateur 2m HT?

    I obtained my Tech license last August, then in December (finally) bought a Kenwood TH-K2AT so I could get on the air. So far, I like it well enough, and I've read a large number of positive reviews of this model on ehams.net, but I wonder what others think of it. What say you, fellow Yahoos?

  • On a DVD-R, a recording was unintentionally erased. Is there any chance of recovery?

    Before crafting an answer, please read and fully understand ALL of this: I have a DVD-R with a perfectly good recording on it that was unintentionally erased (both occurred on the same day in 2007) due to going through the menu choices on a standalone DVD recorder (Sony RDR-GX7) at an excessive speed. Of course, the recorder won't allow reversal of the mistake; it has no "undo" option for erasures. The disc has not been finalized, and nothing else has been recorded on it after the undesirable erasure was made. My konfuzer disc drive plays DVDs, but does not record them, so I have no convenient way to try any special software myself. What I want to know is: Is there ANY method by which to make a DVD recording drive recognise the recording on the disc and write a TEMPORARY TOC so that the existing recording will be recognised by the original recorder? It is vitally important that another recording can be added to the exisiting one, and that the original machine can be used to finalize the disc so that the menu will match those of other discs of similar material. In other words, the process of recovery must NOT result in the disc being finalized! If you can provide useful info, your input will be appreciated. Single-word answers, spurious remarks, jokes, and other drivel will be given negative votes.

Obviously, the users are ignorant or forgetful about the damage that will occur when these things get wet. I don't care about derogatory or joke names -- I can and do think those up myself, and therefore reject in advance anything like "aquadiophile", "iPhonapoolafool" or other amateur assemblages. If there isn't yet a clinical name for these people, a psychiatrist and/or a psychologist with a long history and good reputation should think up a proper Greek/Latin-based clinical term for permanent inclusion in textbooks and lectures.

    I have a 1976 promotional film made for Anheuser-Busch (Budweiser). [Of course, it was narrated by Ed McMahon.] It is a 16mm print with a conventional optical sound track. I viewed it several years ago, and it proved to be in rather good condition. The running time is approximately 62 minutes. Now, before you rush to make suggestions, let me tell you what I have already tried, and that I will vote thumb-down on any response that fails to actually help me. I have googled this thing until my eyes hurt. I was going to ask Anheuser-Busch about it through their site, but decided to try here first. I have looked at breweriana sites, 16mm film sites, ebay, craigslist, and a lot of sites I can't remember, all to no avail. I am fed-up with searching online. I want a different idea. I will not take it to an appraiser, because they charge for their services. I will not offer it for sale on ebay or any other site until after I have some idea of what it may be worth. If you can, please tell me something useful, but I'd rather get no answer at all than suffer with any that won't help.

Don't bother suggesting The Needle Doctor; I already asked them, and was told that they would also like to know where to obtain such washers. I have also investigated having washers made by a company that makes die-cut rubber pieces; the cost would be many times what I can spend. I believe these should cost no more than 15 to 50 cents each in quantities of 1 to 25 or so. I will probably never need any more than that.
