Overall I'm still well up on sales and strangely enough, I do sell loads on the GSP and so does my eldest son now, in fact he reckons, since I convinced him, that he sells more via the GSP programme than he does domestically. --- End quote --- I've done a fair bit on GSP recently and it's fairly painless as a seller. Once it gets to the GSP depot that is the end of your shipping responsibility. I've no idea how much they stiff the buyers for in shipping, taxes and fees though.... --- End quote --- Correct and its at no cost to the seller, the cost is all covered by the buyer, and they know all the cost incurred up front on the eBay page in their respective countries, so the cost to say USA or to Germany, New Zealand etc, is already stated for their countries, so the buyer decides if that is a cost they are willing to pay or not. Many items that we take for granted domestically, are rare as hens teeth in some countries so the extra cost is considered to be well worth it if you can get some rare item of value. |

--- Quote from: Cerebus on July 14, 2022, 04:30:03 pm --- The three phase is what kills interest in it. You just won't see a three phase installation anywhere in the UK where the demand is for less than ~125A single phase. --- End quote --- This is simply bloody stoopid. But, as you wrote, it's a fact of how it's always been done, so that's how it is being done. Single-phase anecdote: Once, I worked with TV. Analog TV, at a production company / OB vehicle supplier. We did a job where the contribution link (the way home for the TV program) was a BT satellite feed. Our OB van, which was the center of mains distribution as well, had a 63A three-phase input, and the venue, being in continental Europe, had supplied exactly that. The mains outlets for technical power were a bunch of Schukos, some 16A single-phase blue MK Commandos, and a couple sizes of three-phase outlets, IIRC 2 off 16A and 1off 32A. The uplink van had a 32A MK Commando single-phase blue inlet.. :palm: Took a lot of swearing and cable bodging before a suitable feeder cable could be arranged. A sensible vehicle woulda had a 16A three-phase inlet; it is immensely more common, and carries 40% more power than a single-phase 32A -- which usually is fused 25A anyway. Oh, and now I work with TV. Again. This time, we're filling a lot less racks, but every bit of kit that goes in draws more watts than the old stuff, so that we're down to half the cabinets and double the power.. Progress! |

--- Quote from: mnementh on July 14, 2022, 06:10:00 pm ---One of the welding shops I worked at was equipped with a huge ESAB MIG welder bought at auction from a factory closure; they powered it with a war-production motor-generator phase converter that was as big as the welder itself. There are ways... but jeez, the losses... :o mnem :-/O --- End quote --- Mmm, ElektroSvets-AB. Almost as good as Kemppi, who are the masters of both rectifier and inverter welders. If you want hardcore, look no further than ASEA-Hägglunds; they made motor-generator sets where the motor is three-phase off the mains, and the generator makes the welding current directly. A dream to weld with, I'm told. The inertia in the rotating mass makes for very nice start currents. |

Boring Mundane Everyday Print #333: SSD Adapter for MacPro HDD Sled https://www.thingiverse.com/thing:1630550 My cheap SSD from Amazon Prime for the MacPro arrived today; of course, this old iron is designed around fast Barracuda spinning rust, not little 2.5" format SSDs. Numerous adapters have been around on Thingiverse for a while; this one looked like the quickest and simplest print. As always, for those who care, complete details and 3DP Nerd-Stats are available in the 3DP Thread: https://www.eevblog.com/forum/3d-printing/3d-printer-yet/msg4300345/#msg4300345 mnem Now to do battle with MacOS Migration Tool... :P |
