Re: Residential Lighting with LEDs: Retrofitting the Pink Ranch

This will surely motivate me to clean my sink better/more often.
I try to keep my kitchen sink task light off for that very reason.

Re: Entropy

I occasionally find bad crimps on FastOn-type terminals that form high resistance connections.
You probably would have seen that though.

Re: home improvement turns into science fair projects?

I don't know if the switcher blob is galvanically-isolated or not.
I doubt it.

The audio "silent switcher" has a ground connection from USB input to bipolar output.

Does the USB 5V outlet on the wall plate have a connection to safety ground?
I don't know but it would be easy to check.

Re: home improvement turns into science fair projects?

Traveling back in time in this thread.... We've started installing USB wall outlets here. The Levitons have two USB ports and two NEMA outlets. The USB is 15W. I would love to have a bunch of adapters that would take 5V USB from the outlets and give me switchable 6, 9 and 12V to replace conventional...

Re: home improvement turns into science fair projects?

I think its Potterchitto Creek at 310 ft MSL about 1-1/2 miles due south. https://proaudiodesignforum.com/images/pdf/MS_Hickory_335797_1966_24000_geo.pdf (Due to the size of the pdf it takes awhile to render at any zoom level.) Your water goes out onto the Hwy 80 drainage system? It looks like if it...

Re: home improvement turns into science fair projects?

I didn't need a topo to figure that out... :lol: I know you know that but is the groundwater water coming from the north? It was a question... I have a similar problem here. We're built on an escarpment and water flows under the front beam wall, through a channel, and out under the back beam wall o...

Re: home improvement turns into science fair projects?

I would go for a new pump and keep the old one as a spare or use both.

Pulled up a topo: Looks like you're at 320 feet in a low spot. You get a lot of runoff and groundwater from the north?

Re: home improvement turns into science fair projects?

Use a WIfi-based moisture detector and a Wifi-based pump controller. Amazon has the flood detectors - I think a basic On/Off function under Wifi ought to be available on Amazon or eBay. The flood detectors are battery-operated. Are there Wifi to X-10 bridges? Velleman may also have something useful....

Re: Phono Preamps

That would have been Logitek: https://proaudiodesignforum.com/images/pdf/US4293823_Balanced_Input_Phonograph_Preamplifier.pdf BTW the "5W" Zener in the above-referenced MC preamp should have been 0.5W since it's only dissipating 56 mW. Question for you JR... If we connect an MC cart between the emit...
