    Advice for my father...?

    OK, built my Dad a nice computer for Christmas (far better than his Phenom II x4 Dell). Specs -- i3-3220 skt1155 + ASUS Maximus V Gene 12gb RAM 2tb HDD Quadro FX570 Win7 I threw the Quadro in there for a few reasons -- (1) it was cheap and I needed something I could pay for (2) I've...

    Quick but crazyish question: painting cables?

    I'm planning out an SFF mod using a Pico-ITX board a friend got me for Christmas a year or two ago. Whoo. (In related news, I hate Poulsbo. I'm a Linux guy, so it's warranted...) I want to, as part of the mod, paint some of the light-grey cables for the mobo to be flat black. I can afford and...

    Anyone [H]ere work for Fujitsu? (Upgrading a thin client...)

    Hello... I have a Fujitsu Siemens Futro S400 thin client. Got it off a fellow [H]ere, don't remember who (no offense meant -- my brain needs a RAM upgrade, lol!). I'm trying to reform it into being a proper, if somewhat low-power, desktop system. I've got a hard drive in it (running XP...

    I built a "Clothesline Racer"...

    Info on Clothesline Racers --> http://www.richardvannoy.info/clothesline-racers.php I found out about it from Make: Mag. Very cool stuff... a lot more potential for fun times in a good way, IMO, than you'll ever get from eg NASCAR. Besides, you get to build the racers here, rather than just...

    Triggering a reed switch at a distance...

    Making an electronic puzzle as a birthday present for a friend who is not on [H] ;) I have a "reed switch" (I use that term loosely, it's not even encapsulated) from a Dollar Tree window alarm. I can trigger it if I get a hard drive voice-coil magnet real real close -- but I need to trigger...

    Anyone [H]ere work for Viewsonic?

    My father gave me a Viewsonic TV -- it's an N2630w, aka VS11749-1M; it's from 2007 -- to try and fix a few months ago. Some capacitors in the PSU went splat. Replaced them and got a blinking red light, so I just ignored it for a while, figuring it was over my head. Pulled it back out earlier...

    SLA Battery Question

    Got a battery this morning, for something I'm doing. (It arrived from eBay.) It's a 12v 4.5aH SLA. Not to big, although it's heavier than I'd like. (That one's my fault, so oh well.) I don't deal with these types of batteries much, but the last one I bought (which was for a UPS) came with...

    Scrounged together an amplified speaker...

    ...for soldering practice and for fun (I'm weird). It works OK. It's loud and it's a little buzzy (boo) but it does make noise so I did *something* right :p Based on an insanely simple LM386-and-a-single-big-cap circuit I found on Google somewhere. Only real mod I made was to add a 100nF...

    PicoPSU Adapter Advice...

    I am the recent recipient of a PicoPSU-120, courtesy of a VERY generous fellow [H]er. I have a compatible power brick, but it is only rated 12v 8a (~96w). I would derate that somewhat, because it is from eBay and does not have a manufacturer's name spelled out on it that I can find... (it was...

    A better speaker for my new toy...?

    Bought this recently --> http://www.ebay.com/itm/201004070756 It has a built in speaker. That's the main reason I bought it -- I wanted to see how they did that, along with how it's controlled (etc). The sound is tinny and a bit buzzy. Probably can't do much for the buzz (internal amp chip is...

    Optical drive cable question, actually...

    A local friend of mine (who runs the tech shop in town) recently gave me a used ASUS Essentio CS5111. It had been determined that the system's board was toast, although I want to give it a second chance before I use the case for something else. It's a 775 box and from what I gather it can do...

    Please expound on the virtues of San Ace fans for me...

    So recently I was given a used San Ace 120 fan, model 9GH1212M405. I'm told it came out of a VAIO desktop... I saw the heatsink it was previously attached to, a monster in my eyes (a quite large --to me-- tower sort of thing, with four heatpipes coming out of a -\_/- shaped aluminum block, with...

    LED Light Bulbs... advice?

    So I have a small hanging fixture in my front hall; Mom and I call it "the chandelier" which is a bit grand, but whatever. It's about seven or eight feet off the ground and it likes to kill a bulb about once a month (or so), which is ridiculous IMO. Probably has to do with the fact that the...

    Wall Wart Question

    So I have a random 92mm fan that someone gave me, hooked up to a random wall wart from god-only-knows-where as a sort of a desk fan. Power switch is from an AT system. LOL. Wall wart is a "Hon Kwang" DC12-50, rated 12v 500mA output. Fan is a SproFan SJ-92X12A, rated 12v 150mA input. After...

    IDE<->SATA Adapters: safe to use, or corrupt your data?

    Recently did a rebuild of a system -- mostly the case, guts are largely the same -- because of, oddly enough, hard drive failure. Of course it's my mother's setup... she's not exactly a tech genius (well, neither am I :p but I'm well ahead of her, by mutual agreement) so I want to make sure that...

    Removing intact coils from very cheap speakers

    I've got this neat idea for a project that needs a quartet of 8ohm coils within it -- not as part of speakers, though. Since 8ohm coils on eBay are ridiculously large and expensive compared to what I'm looking for, I had the idea to buy this lot of four mylar speakers and get the coils out...

    Probably a dumb question -- drill speed control

    Thinking about building something again... as with most of my ideas this will probably go absolutely nowhere at all :rolleyes: I have a drill that I want to rig up as a combination handheld router/mill device and a drill press. It's a cheapish Black&Decker job with a wall cord. I'm picturing...

    Advice: Can I use this CPU with this ex-HP mobo?

    Someone on eBay "liberated" an ASUS M2N61-AR board out of something small and HP. That board is now on its way to me. (I'm aware of the funky power supply connector -- my adapter cable has already arrived.) Here's HP's essentially vestigial specs page for that board -->...

    Controlling Dell Fans >:-}

    This isn't a question so much as an answer (for once). I've known for a long time that Dell fans had an internal speed control, based primarily off a green or blue blob (almost certainly a cheap thermistor) that's in the airflow of every single Dell fan since basically Day One. I've never...

    Doozy: fans spin, but no lights, beeps, or anything else...

    A little advice...? Intel Stock HSFs

    Help me, [H], you're my mod's only hope... :P

    So I've got a thin client I'm modding into a desktop. The only showy bits are some new paint and a decal. I know how I want to do the decal (it's a little ghetto but it'll work) -- but the paint job is a fiasco (and I'm being very kind). I need to turn this from debacle to delightful, and...

    Another doozy: battery operated telephone doorbell...

    Yep. Starhawk's got another goofy project in his head. This time I'd like to make a doorbell. I've got an old telephone bell (from a rotary phone, specifically an ITT clone of the Western Bell Model 500). I'd like the mailman (or whomever happens to wander by) to be able to push a button and...

    A motor-specs challenge...

    This one's a doozy. My mother had (a long time ago) a Craftsman drill that looked like this, only with a battery pack that is missing in this picture. These are the 315.###### series. It wasn't super strong but it got stuff done until one day it wouldn't take a charge. I have no idea...

    Help Needed -- ca.'92 HDD & USB Adapter Won't Play Nice

    A little background first. Mom got her first IBM clone system in 1992 IIRC -- I'm not quite sure what was before that (I was 6) but I'm pretty sure it was an Amiga. The fancy new PC that was Mom's '92 birthday present was MINE ALL MINE MUHAHAHA *ahem* in 1997 or so. I've kept it running...

    DIY LED Bulb -- converting a 240v circuit to 120v

    OK, so sometime in the Precambrian era (by which I mean a few years ago) I tripped over a YouTube vid on building a homemade LED light bulb. Today I found it again, with the help of what I'd scribbled down a few years ago when I saw it last. That video is here -->...

    Surge suppressor design

    So Mom's ten year old UPS finally died... death by drink, to be specific -- it had a splash of orange Crystal Light and that was too much for it; it couldn't tell that it was plugged in anymore. A look at the PCB inside revealed some significant damage. At least the battery didn't short! I'd...

    Random Freezing, or: The Dell That Completely Stumped My Tech Shop

    Hello! I have a Dell Inspiron 6400. No, not the E6400, the old non-E "6400". It's freezing randomly. I want to give as much info as I can, so please pardon the fact that this post is about as lengthy as a PhD dissertation. System specs -- Core2Duo T7200 2.0GHz 3gb RAM (1x2gb + 1x1gb -- the...

    Opening a wall wart that has no screws ;)

    OK, I bought a wall wart on eBay for the purposes of pulling it apart and reverse-engineering part of its circuitry. (It's a long story.) Of course the damn thing is epoxied or sonic-welded shut. It's a 5v 1.05a rated lump so there's not much danger of electrocution -- I'm not stupid enough to...

    Charging SLA batteries...

    I'm in the middle of designing a home-made UPS for a computer. I know how I want to build it. I want to have an inverter that automatically cuts on when the power cuts off. (I think I can do that with an SPDT mains-rated relay. Easy.) At night, I electrically disconnect the inverter with a...

    CX-01 "Android Cloud Stick": is this Linuxable?
