Oh I had thought you were fluent / japanese because you listed yourself as in Aomori! I could write the email then I guess, but I wont be on that side of the pacific for another month or so, so if it'll be interesting how it turns out. Edit: Sent email, waiting for response

Actually if you could contact the people who wrote the doujin you might be able to get your hands on a reprinted / archived version? (even though they do say they sold out of the 3rd volume.. maybe they have the other ones or they're planning a reprint or something?) Edit: i think...

I think this was sold at COMITIA80, I know a few friends who went, so I'll hit them up and see if they have a copy of 3. If not then I'll think of something else. Maybe I can find it somewhere in Akiba? Do you have any idea, being in aomori and all?

I was browsing some sites and came across this http://text.ivory.ne.jp/hph/ Only link seems to be on right bottom but wow. a headphone centered manga (of course its a doujinshi, 3rd volume it seems) Sorry if this was posted before. I guess I'll go find a copy in a month or two while in...

How did you engrave that text in inventor? and also slightly off topic, do you use any integrated / linked CAM software with the inventor CAD?

Nerull can you post black and white pictures of the outline of the traces only? Im guessing I could rout this on a cnc.

wrap the knob in about 2 layers of electrical tape, use locking pliers (vise-grips work) and pull directly away from the knob. make sure the setscrews are all the way out, or else you'll tear off part of the shaft I'd guess either some type of glue like loctite or the shaft getting burred...

1. RoHS is irrelavent for the functionality 2. Sorry, I'm beginning to run low too, but if you're running 18 volts, you can leave TLE not populated and put the midway point of the 18 volts soldered to the VGND pad 3. BoM is fine for that config. I would suggest something easy to handle...

1. Bigger crowbar diode. 2. You're cutting the groundplane... jut have the bottom ground and try and route everything on top or vice versa 3. so much wasted space on the right... trickle charger using LM317?

Gut out the ipod, put AAA and a simple charging circuit.

keep the main board, tap the power line for output stage (output opamp) on your ipod.. you could also tap the I/O and get by without casework. NEVER bypass the protection circuitry of the ipod.. thats just a horrible idea. unless you love lithium fires.

Looks good at least on back of the napkin check... (R6 does look tad high though.. are you sure that one's right?) I think my values were R1 - 1k R2 - 100k R3 - 1k R4 - 10k R5 - 220 R6 - 6.2k

am I the only one who found it ironic that one would "believe" in utilitarianism? Jeremy Bentham would be rolling in his grave like a turbine. Consequentialism makes more sense than Kant to me.. theres too much of what seems like hand-waving in Kant. That is to say, utilitarianism isn't much...

Are you balancing for halfway in between the pot value? thats what you'd ideally do.. also smaller resistor values would allow you to fine tune your values...

R1, R2, R3, R6, R5 are changed, R4 is held constant. buffers must be LMH6321s for very cranky opamps, there is also need for bypassing capacitors. (basically put tiny 0603 capacitor underneath the big electrolytic caps 100uF ones)

pddj - Yes, I got it working, but I havent typed up the part #s for those, its just tweaking the feedback resistor values.. I'm working on my oversampling usb dac right now so I havent the time to finish the Bom I'm sure I can find my old mouser BoM and send it to you if you'd like

everything to do with the dac chip used.. Im not too sure but I think the aria uses the PCM27** or 29** line and those arn't that loud, on the other hand, other dacs like the PCM1739 can be VERY loud (volume knob nearly at off)

Wow thats six degrees of separation right there.. Anyway, do I fail at life if I saw horowitz and thought Horowitz and Hill? (as in the writers of the Art of Electronics)

Meh. SATs are worthless, what matters is what envelope you get on december 15th

Do you still have the cad drawings and the G-code for this? i'd be interested in looking at it.. I've never operated a cnc machine (only manuals) so I'd like to see a sane set of cad / code before I go and ruin a perfectly fine benchtop cnc mill. (considering buying a taig) Sighs ... there...

Tubes for gain, mosfet for output stage.. I'm not insane enough to do multiple tubes for the output stage.. that would result in a ridiculous current draw. okay.. 4 - 5 AA in parallel is fine, but you need more than 6.3 volts, so thats about 5 AA each (if you use nimhs, its more) in other...

The filaments take 300mA? dear lord.. a AAA would drain in 3 hours, a AA in 8 hours. Mm still looks interesting so I'll see if I can make a schem for these at some point tomorrow. edit - as usual I'm an insane human being, so I think I'll go for something like a mosfet output stage.. if...
