Very technical, tells you exactly what to do to build your own headphone amp. I'm definitely going to build one. Doesn't cost much at all and looks like a lot of fun to build. The rewards should be great too. I don't want to pay $200-300 for a decent headphone amp, so I did a search and came up with this. For $20, you can't go wrong ;)
Looks pretty nice. I think I may try it. :)
Only prob is that i'm no electrical engineer. I can somewhat understand the schematic but it's been a while since I attempted anything remotely as complicated as this seems. I guess it'll make more sense to me when I actually have the parts laid out in front of me with the schematics. We'll see...but I will definitely try. I have a radioshack 5min walk away from my house, so getting parts will be easy :)
Let me know how this comes out, this seems like it will be very interesting.
nothing too complicated, just a couple of amplifiers with filter compacitors, built a few of these in class in my day
man I was hoping they had a diagram, all that reading is way confusing.
what kind of quality are we talking here? I have a Sennheiser HD 570s and I want to boost the sound, but obviously it needs to be clean, smooth sound, will this home made amp be able to get the job done?
it can, depends on the quality of the parts that you use, and the quality of your craftsmanship.

And how it looks on the underside:

From what I read, the output is 100% clean (well, .2% distortion, which is WAY less than your regular output from say, your portable). The gain is 21dba, which should be enough to make your ears ring ;)
Looks like a very nice design. I'm going out and buying the parts today if possible. Have to check my nearby radioshack and order all the parts. :)
I'm sure i'll need some help with this project, so all of you knowledgeable people out there can point me in the right direction if I do happen to get stuck :)
Right on ! that sounds like a fun project.
Headphone Amp
What do you guys think of that? Is that worth buying and not building that junk?
You could buy that and spend 2x and less the enjoyment of building your own amp. I'm in the process of building right now, although I do have to go back to radioshack to get a few more parts (i'm missing 3 caps I need and the new project box is too small :(). I expect to be finished with this project after the holidays because i'm gone most of the time. It's been fun so far :)
update:
Got the three caps I needed and got a bigger box. I've been soldering for about 15 min, so far I have the ground bus 90% done, need to solder 8 more connections to make the onboard circuitry complete. Then all that is left is adding the input and 9V to the IC and connecting wires to the output and i'm done with the board. yey. I have yet to drill/wire the box. That'll happen on the 23rd and 24th when I'm back at home. Till then, peace

It was really confused me.
Can anyone tell me what part & chips I should buy?
and do any one know how long the battery last?
There is a parts list included, just scroll down to it. Everything can be had from radioshack. The battery lasts, on average, about 26 hours.
You might have trouble finding the op amps at radioshack. I am building an 80 watt guitar amp (part schematic from online, part my own design) anyhoo, i have to get the LM3875 op amps off of digikey.com. digikey is the place to get components. they are cheap and reliable.
I was hoping for a more comprehensive answer to this... anyone?Quote:

i thinkthat the poeple who are aasking for like diagrams are asking for SIMPLE diagrams, sort of like lego instructions, along with some step by step follow along. i dunno, maybe its just me, but i'm getting somefatty sennheisers for my computer come may so i think i need to build me one of these too, but i cant tell if the instruciton websites are speaking english or not.
for yall who completed this project, how long did it take and how difficult would it be for someone with VERY little experience
