Either cables make no difference or they work as tone controls but you can't have it both ways.

So, what is it finally? Tone controls?

What it is and what people think they are buying are two different things. The vast majority of cables used with the vast majority of equipment does nothing but connect the signal from one component to another with no audible effect on the signal, even though many will claim miraculous changes to the sound.

In a few cases, for example very high capacitance cables combined with very high impedance sources, the cable may contribute to high frequency roll-off. This isn't normal and usually indicates equipment that is not well designed. Also with very long cables all sorts of things, but usually high frequency roll-off, can occur.

So the answer to your question is that people who are spending vast sums on cables are usually looking for some tone-control functionality, though they would express it in more purple, hi-end audio marketing verbiage. What they actually get most of time is nothing different except in the way it looks and what it costs. Many will think have have gotten what they were looking for due to their expectations and they will be satisfied. It's funny how money spent can satisfy an audiophile's insecurity, but human beings (including audiophiles) are strange that way. Babies suck their thumbs, audiophiles buy ever more expensive cables...

FILES UPDATED AGAIN!

There was a major screw-up on one of the traces where Left Input connected to ground at the base of IC2.

Files are fixed. Same links (URLs). EVERYONE needs to update to these files NOW — LOL.

Just make sure you do this, as failure to comply could potentially result in the loss of hundreds or even thousands of dollars.

In other words, FIX YOUR FILES! SIZE=1]Or else![/SIZE] [

I updated all of the pictures; Even the schematic - there were no changes to it, however.

PCB pic has correction of Left-Input and Ground issue.

Enjoy.

I'm also going to try making some prototypes of this. I like it, a lot! Seems OKAY!

PS: I also made sure that the digital potentiometers could handle fast changes and would not mess up due to one being a certain amount of steps off from the other - this could've potentially caused balance issues. The DS1666 can take inputs of a maximum pulsating of 2kHz down time for the input. Maximum 62P Series OREs' RPM is 100RPM. 16 position = 100*16 = 1600. LS7804 multiplier (x4) = 1600*4 = 6400. Minute = 60 Seconds = 6400/60 ≈ 106.7hz pulsing max. NO PROBLEMS HERE! Plenty of breathing room for stepping for the digital pots.

Default HAH!

I just realized that I made a huge mistake! The name of the decoder is not LS7804, but it's LS7084! How did I do this? Just Google LS7804 and you will get tons of relevant results. These guys doing pendulum stuff used the name LS7804 on their site about 4 times and LS7084 only once (generated on a BOM).

I have ordered some samples of these LS7084 from LSI/CSI and am going to buy the rest of the parts to build one as well. I'll keep everyone informed.

Remember: LS7084, not LS7804.

(PS: I think the LS7184 could work for me as well, but for now I'm sticking with the LS7084 )

Default Yay!

THE BOARDS CAME TODAY!

All five of them.

I have them in now: Here's a crappy pic:

Most of the pars are in. I just need the decoder, the digital pots, and the encoder - then i'll be ready to build.

Default Happy New Year everyone!

Hello everyone! I am here wishing everyone a happy new-year and luck on their projects. I am almost completely done with the OREViC project and will have more news on it as soon as I purchase an optical rotary encoder. All the other pars have been assembled on to a board for testing. I accidentally put the voltage regulators in backwards and came close to ruining it, and I had to do a sloppy fix job on the connection. Makes me feel ashamed of such a quick-fix, but I think that the leads have a very solid connection to the board. One of them had to be soldered to the bottom of the board. Good grief! I will test this with the encoder, and if it works, I will attempt to fix the regulators once and for all; I need to go get some more solder-removal braid! I will have more information on all of this as soon as I can get my hands on one of those OREs.
