    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)

    Low voltage AC/DC Adapter

    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)

    Low voltage AC/DC Adapter

    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

    Low voltage AC/DC Adapter

    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)

    Low voltage AC/DC Adapter

    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

    Low voltage AC/DC Adapter

    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

    Low voltage AC/DC Adapter

    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?

    1/4 Barrel Prop, How I made it.

    FWIW I found a 12mm step reamer (part of a kit) on Amazon (And it, the kit, was less than a SAE Greenlee found at home stores. Nothing like having Metric tools for doing exact, metric holes
  17. A WAG only Looking at that cord, I guess that is a just rectifier in the bulge to feed the polarized (offset) connection. IMHO simple ON/OFF should not pose any more problem than any other string type. SPT wire will handle the load with ease

    Disco Ball Motor Question

    100% or 0 only. It probably has a synchronous motor (like old plugin wall clocks and phonos) Outdoors If you hang it INSIDE a plastic shelter (upside down tuperware. no lid needed) shelter from rain. I don't think you can make it resistant enough base mounted
  19. The 80% rule applies to all things electrical. Continuous loads (4+hours) shall not be run over 80% of full rating. I suspect you light are not all on at the same time, so short excursion to 100% is allowed. BUT you have a cheap supply. Why push your luck? It could fail clean(just give up) or it could fail dirty (voltage spikes)
  20. The fan should be thermally controlled. Depending on the room temps, the fan may not kick in until the PSU reaches 30-50% steady load The singing is the PWM increasing ON time with the load. (a 'good quality' transformer should not 'rattle' under load. These are 'cheap' supplies.). The (chemical) smell could just be out gassing from a improperly cured inductor. Run it hard in a (if it catches) FIRE SAFE location to see if it will fail BEFORE the show goes on. have a spare PSU on hand, in cae it does BUT Blue Lugs? Any CMB24 bank can draw 30A (when maxed out). you want 12ga minimum (for short runs) and Yellow lugs

    Amp rating for Pixie Boards

    18W /M is hefty. That is HEAT, so also be prepared to mount on a surface that will help sink some of that away. inline automotive fuse holders that take the Wedge fuses used on the CMB24 are common, or you can use a 'marine' fuse block. The strips I have, are similar to those used by BluMan, 3A/5M

    Amp rating for Pixie Boards

    I'm with K6ccc. I have serious concerns on any string running with an input of 7.5A. Even if the +12 lead does not fuse (simple word for burn out), the voltage drop will be serious, even with 18Ga copper wire.

    Best way to ship controllers

    USPS Flat rate boxes are a bargain. Just remember, the insurance is minimal (does not include the postage). UPS includes the first $100 free. Can't remember FEDEX Express (different from FEDEX Ground)

    RGB Flood Sequences

    Do you use 'Barn Doors' on you flood in those narrow spaces?

    Trip Wires with inputpup

    Gas Stations used to have Bells when you drove over the hose. http://www.milleredge.com/air-switches-hose-accessories.html The nice thing, the hose can be long and is not affected by light or door width.
