Hey all,   Does anyone know the hole diameter for the four PCB mounting holes?   Thank you very much in advance.

Hey guys,   I built a GrubDAC a while back and it sounds great. However, my one gripe with it was that Windows 7 didn't like it all too much. If I wanted to change the volume, I had to go into the advanced mixer and change the volume on each program separately. I could not simply pull the...

Ehh don't waste your time. I don't think. The ripple on the 5V rail of your computer can easy be dampened with some high value capacitors.You could also use a filter network to get rid of the junk on the rail if it really concerns you.   If you are still convinced, It's as simple as an...

Thank you so much. Makes sense.

Right thanks! I realized that I had just said something dumb. I know what a buffer is. Dur!   However, Just a question, why does the signal need to be buffered? I understand what these stages do, but I'm not quite fully understanding the theory behind all of them. The microphone is a high...

Alright thanks.   Electret mic -> Buffer -> BP Filter -> EQ -> Headphone amp -> Headphones   How that sound?   What kind of buffer is that? Current/voltage?

Hello,   Working on a little "hearing aid" project.   The mic will be on the same board as everything else so it's not a matter of long cable runs and picking up noise on the way etc.   I have a question about how the different stages should be laid out.   Currently I have been...

Is FAT32 slower than NTFS?   I still find it absurd that they can pack 64GB of storage into a a microSD card. I'm not old. I'm 18, and I remember when my computer's hard drive was like 400MB. Sheesh.   Thanks.

Thanks a lot for the replies. I think I am going to purchase one. Seems like an excellent value. CZ + a 32gb SD should do me very well.

I see tons of posts on HF with love towards the Clip Zip. It does look like a very nice value player. Really!    But if I go on Amazon, nearly half of the reviews are "Died in 2 days" "Dead in the middle of a song" "Wont Turn on".   This sounds very much hardware oriented, to me at...

Arrows build is simple and well designed. The only thing I want to add is perhaps instead of using two potentiometers to adjust voltage on both rails...you can use a circuit like this:   LT150A is EOL or discontinued I believe, but it can be replaced with another regulator like an LT1083 or...

Oh I'm not blaming TI. Even though TI has huge market share...whether they got there fairly or not...I don't know, I like them.   Just wanted to comment on the actual GrubDAC. I'm using this hooked up to a homemade power chipamp. About 50Wx2 + 50Wx1 (sub). Bass is so much more punchy. I...

Ugh...Now I kind of don't like W7 anymore. Damnit. Colbaltmute, I think you should add that to the GrubDAC page: that it may not work too well in W7. It will work...just not as  you might expect.   Hmm....replacing that PCM might be a pain in the arse since everything's already in place and...

So can it would be a pain in the dupa, but can I solder on a PCM2706C?

Well I'm on a computer that is shared amongst people in my household. So I can't just suddenly have the volume slider not work...   The problem confuses me a lot because traditionally the volume bar with control all of the programs volume at once. In the mixer you can set each individual...
