Here's my latest audio project:   It's a SSMH based on Fred_fred's board, and Sylvania 12au7's. Sorry about my super-messy desk ;) The bread-board enclosure is just a temporary home until I can make up a metal case for it, but I kind of like the super basic look for now... I've buffed the...

Hello everyone,   I'm looking to buy a headset to go with my galaxy s3, that I can use while I'm out and about, and not worry too much about keeping in nice condition or losing. I have only a couple of requirements. I need an in-line remote that works with Android and has volume and pause...

I dig this design! I've been thinking about doing something similar myself and I'd love to see more detail on how you put it together.   Is there any chance that you could provide me with schematics/board layout/BOM/anything else of value?   I'd be super appreciative :)   Chris

After looking further I realized that a donation is required to get the info on the website! I thought the downloads were just down or similar, hence my asking. I'm not interested in taking the creator's designs if he wishes to sell them (/donate to get the privilege of seeing them) as I fully...

Quote:   Oh my god, this is beautiful. Just plain gorgeous. I hope it gets a nice enclosure to live in!   I've been bogged down with other projects that I'm working on (particularly a high end electronic-cig driver board with micro controller controlled VV/VI/VW settings and other...

I do tend to waffle a bit... sorry about that. my intention was to make this project its own thread once development was at the refinement stage, right now its very much just a learning process still, which I thought would be cool to let other people in on As for Dave's videos, I find them to...

Quote: It's called Diptrace. It's really pretty wonderful. It's the only piece of software I've tried that's actually intuitive in it's use. It has 4 components, that being, pcb editor, schematic editor, and editors for components for the schematic and pcb footprints.   I've tried...

The latest in my line of "micro moy" boards arrived today...           I've stuffed one board most of the way now, I'm very excited to get the last caps that I need and try this out which shouldn't be too long now. I tidied up the design a whole lot over the last prototype, it's...

Hey, please let me know if you go through with the digital pot, as I'm very interested in doing so myself. It'd be hugely helpful to know how someone else tackles the problem.   In regards to o2's...    peace

Wonky parts alert!!    However, I'll bet the o2 is sounding great, even if it was a big pain to build. Mine went together easy but sadly had a few tracks go bad after swapping components too many times... So I'm waiting for a new pcb so I can build it again!   Just another note, you...

00940, I love your build, its clean and elegant. respect!   I was hoping someone could help me out with something really simple for the next run of my boards. I'm not 100% sure of how i shiou,d be wiring the pot in my cmoy based amp. I'll include an image of how it's routed now. The other...

Defqon, were you aiming that question at me? This is my own design. I'm considering selling some pcbs or maybe made up boards if there's demand, but this is just a prototype that you're seeing at the moment. (I'm calling it the Micro-Moy)

My chicken's good- rather crispy. (at least the legs were, i didn't try any other parts today ;))   The buf-634 is simply providing a virtual ground for the opamp. I've found it to be a fairly good component for this, it puts out a lot more power than any op amp I've ever tried in it's...

I got these in the mail today...  Put one together. I'm currently trouble shooting it, I shall let you all know how it sounds once I've got it working properly. Looks cool at the moment at least!   and a good day to all   chris

Well, I have a few photos of my current builds... There's a prototype cmoy SMD, and a TDA2050 gainclone that I'm building up.   I took apart an old rear projection TV today, it was specced 100% with nichicon caps, all pretty decent series too, so I spent a couple of hours de-soldering them...

Well, since this is a post pics of your BUILDS thread, rather than a post screenshots of your board designs thread, I thought I'd put up a couple images of my first prototype that I just started assembling tonight. At this point, I'm just waiting on the SMD parts from RS, hopefully that'll be...

Hi all, I've been working on a project in the past couple of days, while trying to teach myself to use Diptrace a bit better, and at the same time solving my problem of not having a truly pocketable headphone amp.   My design is a tiny, smd based Cmoy-style amp, which will be usable with the...

Hey everyone, I was hoping I could get some advice on parts selection in my o2 build... Its almost finished, but I'm stuck on this and could do with some input.   I haven't had any replies to my topic on diyaudio so I figured I'd post here where a lot of people read in hopes someone could...

Quote:   I really like this wooden enclosure man. Well done. Unlike most I've seen, it looks sturdy and you're got the joints really nice and tight. The cooling grilles and two-tone look is a good one, very professional.   I'm very tempted to attempt a wooden case for my next project...

Quote: Ahh, I do know that the alkalines are much better. In my situation I'm going to get a few nimh cells 9v sized soon for portable amp use. The choice I made was when I took the photo, and didn't have enough money (3ish dollars) and had to get the crap battery, cos I needed it...

Beautiful! Did you use the box enclosures case specified in the bom? I was considering the same idea but with plexi and lit with some LEDs. That looks super classy

Sup guys (and girls)!   I've been working on a few projects recently. Most importantly though, my SkeletonDAC arrived in the mail. I think I might be using it internally with my objective2 (in the battery area) for a desktop dac-amp unit. I shall post my other projects soon when I have the...

Woah, I just read up on the 2107, that's a serious op amp very fast slew and higher bandwidth than most I've used, I'm surprised that you can keep it stable, what cmoy board did you build yours on? I want one!  along with one of those chips to try out. I'm bummed out that I cant get the 6558...

Thank you!   In all honesty, the highest regulator I had sitting in the junk box was a 10v one. I've run it on 18v in with batteries before however, and it didn't really sound any different to me, basically all I noticed was slightly higher max volume. It could be partly in that my cans...

Hi all, I've posted some images of this amp in the DIY project gallery. I've finally sorted out the niggles I was having with it, and finalised the wiring and whatnot, So I thought it deserved its own thread.   It's powered off a 19v switch-mode laptop PSU, and that is dropped down to 10...
