Re: Anyone here ever mess with UPS's ( back up power supplies )

Add an autotransformer (Variac) to get your 120 VAC.
Probably more trouble than the UPS's are worth.

Re: Need 36v charger or PS.

How about 3 12-volt Deep Cycle batteries and a charge controller? Charge the 12's individually.

Re: Ahooga!

I've used those RF modules, and the $12 receiver/transmitter fob (including battery!) has the option of momentary, toggle, or latch with a single button. Nice job though, getting your one second delay from a cap!

Powder coating power supply

Anybody play with powder coating? I have one with a small high voltage module that takes 120 VAC and outputs (technically) 11,000 volts. Unknown current, probably milliamps. This one has zero output, and the manufacturer says it'll be months before they have any more modules in stock. It's fully enc...

Re: Structures

Welcome, rash-
That's a common question, on everybody's mind lately.
If yours is regarding the blivit data structure, you'll find the inverse logarithmic recursive function applies, while the data structure of the n-th dimension requires compliance with asymmetrical contrasting cardinal grammeters.

Re: Ham License

I used to own the call WA2RBA, but US Air Force came along, and never got back to it. Spent many a sleepless night on 20 meters looking for that long distance DX contact! Italy was the longest contact. Maybe get back to it someday! It's a terrific community, especially for do-it-yourselfers!

Re: Antenna Cable Routing.........

From the diagram, you're also running the cable through the Surge Protector power strip. That's a no-no, as a Spectrum tech removed mine as causing all sorts of interference in my whole neighborhood. Sure, not all Surge Protector strips are equal, just a word of warning.

Crazy idea- could you use a software-defined radio? https://www.amazon.com/RTL-SDR-Blog-RTL2832U-Software-Defined/dp/B0129EBDS2/ref=asc_df_B0129EBDS2/?tag=hyprod-20&linkCode=df0&hvadid=309707619534&hvpos=1o1&hvnetw=g&hvrand=10005290042573975653&hvpone=&hvptwo=&hvqmt=&hvdev=c&hvdvcmdl=&hvlocint=&hvlo...
