    LOR 4.3.28 crashes after install

    I had to reboot, then still needed to run a Repair Install W10 x64

    Pixel Strips

    I just made mine out of plastic Plumbers tape using a piece of 2x4 with a few headless (cut them off) finishing nails and a 12mm Step reamer in the cordless. The pins hold the tape centered on the clearance holes in the 2x4. (I do sets of 4 at a time, every 4th hole, which matched the max distance on my HC bullet nodes )

    What voltage? 120VAC or D12VC Monochrome or dumb RGB?

    Low voltage AC/DC Adapter

    Back in the days of tube car radios, they had a 4 pin module called a Vibrator to chop (and switch) the 6 or 12VDC feed to a transformer to that raised the voltage to 200-300 V for the B+ supply. (Here is a e-bay link for a picture https://www.ebay.com/itm/4-Pin-MALLORY-Auto-Radio-Vibrators-J12F-Type-6634C-RCA-110050-1-Untested-2-Pcs/392042053364?hash=item5b4786fef4:g:N7AAAOSw32lYv2lG ) These were mechanical switches, that vibrated back and forth. The contacts, were switching Inductive loads, so the soon became pitted and the unit failed. Along came the Transistor and some bright sole packaged an oscillator and a pair of switching transistors into the old package for a direct plug replacement. I think you might have the modern version, sans transformer ( chopper modules I googled, all have transformers)

    A WOTG (Way out there Guess) 😜 😜 You created a ripple pass filter. If you follow the conduction paths on a reverse wired bridge, (DC on the + / - and load on the ~ ) there is no way to get any difference voltage at ~ I wonder (since there are ZERO p/n markings) if you have a custom chopper module in a standard package. just because I have never seen one of these beasts, does not prove they don't exist. (the bolt hole is to mount and add extra heat sink capability)

    Brush type motors are usually Universal. AC/DC Some motors are really DC, but include internal rectifiers to allow AC suplies. I am totally with K6CCC. No way will a bridge create AC I am a graduate of the US Navy Electronics (Radar) schools with 50 Years pushing Trons under my belt

    Simple: it is DC leakage. The AC (setting) input gets rectified and the resistors adjust for average RMS (there are a few True RMS reading meters. They cost more) There are very few multi-meters that have a DC blocked input (labeled Output) like the old Simpson 260/270 did

    35V is the next standard RATING above 25V. Like the CMB24, capacitors have Max Ratings also. 35V does not mean it makes 35V out of thin air. that lighting pak is 12V RMS. a 'magic number used in full wave AC to DC rectification: 1.414 (the reason I also recommended a BUCK regulator) Since the pak is also unregulated (Sola type lighting paks would be horrendously expensive for a typical application that usually has a wide tolerance)

    This kind of thing was a Radio Shack item. We have Fry's out here :/ for parts (if they restock). Jameco (in San Carlos, CA) is good for Mail order You want at least 25V. 35V is great headroom https://www.amazon.com/dp/B015O7O068/ref=sspa_dk_detail_3?psc=1&pd_rd_i=B015O7O068&pd_rd_wg=fIiSH&pd_rd_r=Q0EGKYQDV51YWDDF5PZ0&pd_rd_w=Pr2Jh

    Half wave? 1 diode? are you using a supplemental 12V for the electronics? 55Years as a ET, I tend to err on the conservative side. The cap will also soak up minor load change surges. BTW, we are talkin' a couple of dollar part.

    You might add one of these just before the CMB24 https://www.amazon.com/DROK-Voltage-Regulator-Converter-1-2-36V/dp/B07CK1L5G2/ref=sr_1_7?s=industrial&ie=UTF8&qid=1527728930&sr=1-7&keywords=buck+converter Bridge -> Capacitor of a few hundred uf (basic capacitor filter) -> buck regulator -> cmb24

    Ungroup the channels for that port, then you have 3 independents lines: 2 for your rope, 1 for any monochrome light. just remember 4A load on the + and don't push the sink lines (R G B ) capacity by using injection

    Low voltage AC/DC Adapter

    A bridge rectifier and a good filter capacitor will make DC (with ripple). The problem, is the 13VAC will be closer to 18V DC Your Yard lights (incans) don't care if it is AC or DC, so replace the Power Pak with a 12V weather proof PSU The convention is the cables RIB is Minus (or Neutral)

    You Need These Pliers

    Hey! You are spilling all the secrets us Electronics Techs have know for years. Next you will blab about nibbling tools, greenlee punches, solder wick

    No LED light

    Check the pins on the RJ45 jacks U1 is a RS485 driver IIRC there is a AUX 9V also on the 8 pin jacks. Solder Bridge? Bent feeler wires inside?
