Re: its always somethin
In one of my weather instruments using AA batteries the negative coiled spring gets pushed off-center by the battery. When I remove the battery the spring is hung in place and I have to flick it to get it to extend before installing the replacement battery. It looks just like all the other springs s...

Re: The MTC-MS-II: An Improved Precision Mid Side Matrix
Thanks for the feedback everyone.
I'm doing layout now and have managed to get all ten relays on the board.

Re: Entropy
12-15 uA?
Wow that's a good 26 dB more than my 700 nA.
I don't think any of it's leakage. Just pure battery.
I want to put the scope on it and actually see the polarity change.
Suppose the current flow produces noise?

In Search of the Equipotential Kitchen Faucet
The Accutronics reverb springs sort of fell into place. The top ring is coupled to the bottom one by a section of spring behind the turret. This ties all four sections together bringing them to equal potential. The top spring rides on the ball always seeking the smallest-available diameter. The bott...

Accutronics Reverb Spring Prevents Galvanic Corrosion of Kitchen Faucet
I would be willing to bet most, if not all modern faucets have this problem. I may need to take an Ohmmeter on my next trip to Home Depot or Lowes. Problem solved. I took an Accutronics reverb spring (stainless IIRC) and made a collar that rides on the joint between the base and the collar. The sink...

Re: Entropy
I found an additional cell. Grounding the base doesn't help the sections above it because the four sections of faucet galvanically float from each other. Curiously one of the cells in the stack is polarity reversed from the rest. The only way to equalize them is to put metal shims between the sectio...

Re: Entropy
Back in 2015 I wrote here that I had to replace my four-year-old kitchen faucet. Last least year (2017) I noticed pinholes on the underside of the two-year-old faucet arm. I replaced the two-year old faucet with an identical (cheap) one. I began to think there might be galvanic corrosion. The supply...

Re: The MTC-MS-II: An Improved Precision Mid Side Matrix
By switching the THAT1240 in a unique way its gain can be varied from -6, to 0 and to +6 dB. This eliminates the requirement for additional gain or attenuation stages that would add a differential phase delay to one process path but not the other. High frequency crosstalk performance is maintained....

Re: Entropy
Now you need a "Cotton Region Shelter" to put the remote in. Plans here: http://www.proaudiodesignforum.com/forum/php/viewtopic.php?f=12&t=476 https://upload.wikimedia.org/wikipedia/commons/thumb/0/0e/2010-09-16_Cotton_Region_Shelter_containing_Maximum_and_Minimum_Thermometers_and_Stan...
