Re: LM358N or other IC for balanced input?

What I'm trying to do is isolate the input ground from the unbalanced input of an amp. I had a topic on the issue before on a slightly related issue (power rail noise) and is an amp I'd built based...

Question LM358N or other IC for balanced input?

Talking Using CrapCaps in audio amps to hear tonal effects?

This is more of a 'for fun and amusement' topic but with some serious undertones to it. To those whom have built their own amps - have you tried CrapCaps on the feedback, Output Coupling or other...

Re: Monitor's 1920x1080 vs. native resolution

I gave up trying to explain that to others long ago sadly. Apparently 'higher fps means you play better' according to some poeple. Like 100,200, or even 1k fps (despite highest possible image...

Re: 4K monitor - should I?

If 4:3 or 5:4 4k monitors came around I would definitely say yes but only the heavens can grant that in a 19" package. As it stands though- there really isn't much to gain save for a sliver of extra...

Re: Adobe Flash woes... again.

Only by default it will run software mode in windowed. Otherwise when changed to hardware render in windowed mode it will only then software render when it's set to 144p for some oddball reason.

Re: TEA2025B - Heavy noise over V++

Blah, cannot edit post at this point *shrug* Anyhow.. Tip120 worked quite well due to a minimum flat DC gain of 1000 up to 3A/3v (so 1000 gain at 9 watts). However the saturation voltage caused a...

Re: What do real rubycon yk look like ?

I have a bunch of YK's I had salvaged off an old plasma TV board long ago. The 16v capacitors I have definitely don't have that dot in the center of the bung but it otherwise matches. I do agree...

Re: Won 8GB DDR3 on ebay for a good price.

As for overclocking...

Re: Conductive Ink Pen - how to apply without bridging when there are multiple traces
