can anyone who builds electronics tell me how much this would cost?

[gplanet]

I pulled this do-it-yourself headphone amp project from HeadWize, and their forums don't get much traffic compared to these so i'd like to ask here if anyone can figure out about how much it would cost to build one of these.

Here's the link: http://headwize.com/projects/showproj.php?file=kemhagen_prj.htm

If you scroll to near the bottom of the page it says $39. So I would guess it costs around $39.

If you look through the whole thing it has prices for many of the parts.


<< The volume control is a Bourns model 91, plastic type, 10K log taper (ELFA order number 64-256-07) and costs 142,5 SKR (approx. $15 US). The 4PDT switch for the power supply (ELFA order number 35-203-01) costs 99,25 SKR (approx. $11 US). >>


Not sure if that is what you are looking for though.

umm, the box alone is 39... i think that's what it says... i dunno about the electronic components though.

bleh..it also looks like the Input is a 1/8" stereo jack. can anyone tell if it would require extensive modification to just use stereo RCA inputs instead?

Hmmm... I build my own electronics from time to time... I'd say those parts would probably come out to less than $20 if ordered through digikey (you can use your own cheap pot). But you'd have to build the pcb, and that'll cost like another $10-$20 depending on how skilled you are at prototyping.

All together, I'd say less than $40.

i just found out $100 - $160 from someone damn that's too much. it's the opamps ($13 each, and hard to find) and the box ($39 total) that make up almost the whoel cost

make your own op amps, should cost you pocket change in that case.

If you lose the box and build your own op-amps, it should be doable for sub-$10. Just don't shop at radio shack.
