my UM1 cable caught on something the other day while the phones were connected to my ipod and wrapped around my neck. disastrously, the headphone wires ripped right out of the Y-split. i'm planning on re-soldering and heat shrinking the Y-split to repair the headphones, but i don't know which...

this isn't strictly HEAD-fi, but i'm wondering if anyone can recommend a DIY power amp that's suitable for use with a subwoofer (actually, it will be used with an enclosure that contains TWO 12" woofers, 4R impedance). i realize this is quite a tough load to drive well, but if anyone's dealt...

it occurred to me this evening that it would be very helpful for all of us electronics DIYers, especially those just getting started, to have a comprehensive list of electronic parts stores in and around major metropolitan areas. a quick search didn't turn up any such list, but if one already...

yea, i know, HEAD-Fi... but i figure someone on here can probably answer this question. i want to make a couple of S-video cables (rather than buying them), and i have some Canare Star Quad on hand. the S-video specification requires two signal wires, each with its own ground. am i correct in...

i'm looking to buy some calipers to make accurate small-scale measurements easier. i see that harbor freight stocks a line of Cen-tech calipers, but i'm a bit dubious of their quality. my question is this: is it worth it to spend a bit more on calipers from somewhere other than harbor freight...

i just put together a TREAD from one of Tangent's kits, and i'm having a couple of problems. i'm using the circuit with a Jameco wall wart, 24VDC 500mA. the transformer puts out 28.9V unloaded; i'm getting 26.5VDC from TP1 to TP3, and 25.1VDC from TP2 to TP3. fine. however, i can't seem to...

since putting together DIY headamps has been one of my first experiences with soldering, i have a very basic question - is there an environmentally friendly way to dispose of leaded solder waste? i've thrown away tiny pieces, but i'm about to clean out the receiver under my Hakko's sponge, and i...

i'm putting together a BOM for my first PIMETA with a TREAD power supply, and i want to make sure i order the right parts and connect everything properly, especially since this will be my first experience with building a separate power supply. as such, i have a few questions for those who have...

has anyone else been having problems sourcing BUF634 chips (both DIP-8 and SO-8 packages)? Digi-Key, Mouser, and Newark are all out of stock, and Digi-Key customer service can't even give me an estimate of when they'll be receiving more. apparently, TI hasn't supplied them with any lead time...

i'm still an audio DIY newbie - i've only built a couple of CMoys and a Mini^3, with an Alien DAC in process. i'm now looking for my next project, which i'd like to be an exclusively wall-powered amp for home use. i've listed a few of the obvious possibilities in the title of this thread, but...

i've been using 60/40 solder and decided i'd like to try some 63/37. i've found some that i think is a good deal on eBay (~$13 for 1 lb, 0.031", if i buy 2 rolls), but it's a core size of 58 rather than 50, which seems to be more standard. this translates into twice the flux content (2.2% vs...

(to those of you who read headwize.com as well, i've posted the same thing in the DIY section over there, in hopes of getting some good advice. sorry for the clutter. ) i'm looking to upgrade from my high-class, $8.99, 15W ratshack iron to something a (good) bit more capable. i've just...

i have a soft hiss in my CMoy when listening to my iPod through very efficient headphones (25ohm IEMs). the hiss goes away abruptly when i lower the iPod volume to zero, so i assume it must be the source of the noise. i lowered the gain from 11 to 5 by replacing the R3s, and i think it improved...

hi all- first off, let me say that i'm a complete electronics and DIY newbie, so if i ask anything laughably simple or obvious, try to avoid openly making fun of me. chuckling behind my back is fine, just as long as it's not overt. in any case, i just built my first CMoy, following...
