Hi all.
If there is one of those AR2 receivers behind the spider webs, please let me know.

Hi. It could be better approached as three window comparator circuits. One between 4.9 and 5.1 V to turn on led '5V' ; One between 8.8 and 9.2 V to turn on led '9V' ; One between 11.7 and 12.3 V to turn on led '12v' ; or with the tolerances of your preference. If that fits your wishes... Perhaps a L...

Hi. 36V usually charges at 42V; times 8A is a sustantial ~400Watt capable charger with few target products. A few this site sells: ----> https://www.aliexpress.com/item/32742206305.html?spm=2114.search0104.3.179.7aa94d31ZCSWuB&ws_ab_test=searchweb0_0%2Csearchweb201602_8_10065_10130_10068_10547_3...

Use a CRT high voltage flyback transformer sawed-off section from a defunct TV/monitor PCB ? You want DC.
Older copy machines have a high voltage module, very canibalizable. I have one at 7KV if suits you for $0.

There is also another factor while testing/evaluating the energy delivered by batteries, usually not published; or they come up with it when there is a complain : Test duty cycle.
Manufacturer may want 5 minutes drain, 10 minutes rest and repeat; or whatever they decide.

What do you mean by "polish"... ? A wax, a polishing compound, a buffing compound ? Perhaps peek at the MSDS of the product you are curious about; may have clues on pigments. Here is one----> https://www.thetreatment.com/product/the-color-treatment-color-enhanced-liquid-car-wax-16oz/?doing...

Gas powered lights had their era; unlikely to return...

Thanks, haklesup. Yes, bought broadcast FM receiver kits that use a TA2003 receiver chip, modified for 118 - 138MHz Rx and are working very well, (with distorted audio from FM demodulation that I do not care). Ordered AD8307 chips to experiment if those detect 10.7MHz at the chip IF node hopefully t...

Hi Tzap. I would test first for signal sufficiency and insert a preamplifier only if weak, at a point before signal gets distributed and passes so many connectors. That would be LNB output. Perhaps the diplexers/switch/splitter could be modified disconnecting their (choked) power path/feed ports goi...

Hi.
Do you know of an IC like the NE567 audio tone decoder (detector) but for RF ?
Looking to detect the presence of 11MHz or 130MHz, turning a LED on.

Hi.
Consider if your satellite receivers DC fed on coaxial to the dish LNB do not interact improperly with the path trough/into several devices.

Yes, congratulations for Dacflyer ! It has been many years; from the days of Chris and 'pulling rice'. The earliest group that I remember originated middle nineties at a Microsoft forum, then migrated to a Popular Electronics forum, then to Electronics Now before Nuts&Volts -if I have it right-

Very right, CeaSaR.
The product of the non-stop-growth of laziness. Easier to massage a keyboard expecting a solution than doing real diagnostics. Too much work to unscrew spark plugs!. And not returning the replaced 'bad' parts to the owner. Easier and nearer is the garbage can.
