    tv repair

    I hate it when the "electronic" problem roots back to something that is a little piece of blow-mold plastic, that just broke, and there is seemingly no kind of glue/epoxy that can fix it, half the time you can't even put it on right because the part is so small. Yeah I'm bitter...LOL Matty-

    testband

    I was able to view the attachment, its in PDF, and I have an understanding of what you are attempting. Honestly I think your idea is great, but can you give us more details on where you are having problems with the micro-controller? NOTE: This may also want to be posted in the...

    Looking For Radio Shack Model # TRC-440 AM/SSB CB Transciever

    If you can give me some solid info on approximately the year, and if you can take it apart and get some other things like any revision numbers (if applicable) or any other kind of identifiers. I have ARCHIVES (and I mean that) of CB service manuals, I can take a look for you, it may be a few...

    From mp3 to Sound System

    Okay, what are the devices on each end? We may have an issue with the level of the signal. Example: Mic level output going into a line level input... not so much Line level output going into a mic level input... turn it down... but okay Speaker level output going into a line level input...

    From mp3 to Sound System

    oh yeah, I am a huge fan of the majority of the gadgets on that site... and I would probably never tear something like the watch apart because I could totally see myself using it at work :-).

    From mp3 to Sound System

    It depends on what you'd be going for... if its just the time, then it wouldn't be impossible... the display itself may be a little big, what I would suggest, and maybe this is my geekynees coming out, is that you see if you can get a small display (the simpler the better, I like binary for...

    Good SOund

    Oh yeah, You absolutely can put something nice together with a decent sound card, and honestly I haven't used much for analysis software... maybe a good avenue to check out. My biggest hurdle is the fact that a lot of people still don't hear some of the differences :-). Oh, and with the...

    Recomendations for equipment.

    Hey there all, I have been really busy lately, but I wanted to sit down one evening and get some ideas from all of you out there. I may be moving within the next 6 months or so, not far, but I will be picking up a roommate, who is as much of a geek as I am (this could get interesting!!). He's...

    Good SOund

    Well I say its subjective for one reason, Human error / preference. For example, if someone is unable to hear the difference between 2 systems, even though lets say I can, then they won't care as much or maybe they just don't have the "trained" ear... I say that with quotes only because my ears...

    From mp3 to Sound System

    well I can tell you this, standard wiring of a headphone connector (stereo) or TRS connector: Tip - The very end of the connector - Usually Left channel (positive L - #3 in pic) Ring - The part between the 2 insulating rings (#4)Usually Right channel (positive R - #2 in pic) Sleeve - The part...

    Good SOund

    Good sound... that's one I used to hear very often when I was working @ Radio Shack.... some people would come in and compare components and speakers to things WAY more expensive, and others would come in to BASH everything. Good sound is frankly very subjective, and personally I think it...

    What Is Your Favourite Operating System & Why ?

    I use 3 different systems depending on my needs... Windows 7 64-bit, booting on the same system with swapable hard drives (note, NOT dual boot), with a common drive, Ubuntu or any debian based distro. Currently ubuntu is what I am typing this on. And I have both a Mac and a PC laptop...

    Dell w2600 lcd tv

    Wow, that was a pretty crazy bump! I would be curious to see your results, I don't have the exact same TV... but I have a monitor with the same problem, wonder if they are anywhere closely related? Gives me another area to check when I get around to it :-)

    Apple Newton MP2100 Repair

    The big reason is probably because the Lithium Ion cells at the time were not as effective as we have today (at least that's what I recall). Not to mention, size, voltage and honestly, the gain of using that chemistry vs. a decent super cap.... it was probably not very viable at the time, and...

    Apple Newton MP2100 Repair

    I've seen these in some strange older laptops, there may even be some newer ones out there I think the [M] has to do with Mashushita (manufacturer) who is the main company of Panasonic. On a side note, I think is really cool you still have a old Newton, they were fantastic! Matty-

    "Lafayette" LSG-10 Signal Generator

    Sorry it took so long for me to get back to everyone, but here's some answers and questions and such: 110khz to 130mhz (I think... there are multiple labels towards the bottom of the scale, I think it has to do with harmonics, but the lower numbers start @ 120mhz to 260 mhz. Speaking of...

    "Lafayette" LSG-10 Signal Generator

    I'm now onto a new project.... Now that my scope is working properly. :-) I have a bit of electronic gagetry, mainly because I tend to snag interesting looking things, and I am an aspiring Ham radio operator... so I love learning about all kinds of stuff, and honestly, what better way to...

    Tektronix 475A Display problem [Horizontal?]

    I believe it was the bridge rectifier, the cap seems fine, but I don't have a great way of testing it. From what I was reading on a few different posts about bridge rectifiers, I was getting some wacky results: Negitive lead of DMM on: DC+ side AC1: 5.90 Mohm AC2: 4.30 Mohm NEG: 1.3 Mohm...

    Tektronix 475A Display problem [Horizontal?]

    Update: So after a fun evening with my friend (who has a slightly better soldering/de-soldering technique than myself), we managed to replace both the bridge rectifier, and the GINORMOUS capacitor. however, when I was getting some of the camera shots in the previous post, I blew the mains...
