    I vaguely remember that the line frequency was around 31kHz coming out of TNC, at least the 355 I hooked the setup to

    I did a mock up to test the circuit in case I ever need to change displays on my TNC155 and TNC355, it did work...

    I haven't done much of this myself, but I remember being told that it is a good practice to pre-wet the edge to be joined, soften it up, then position, and then drag the needle with the solvent, and...

    for once I agree with that move, diesels should have stayed where they can run at narrow optimal rpm range to reduce pollution, the whole principle of operation is one big pollution factory - it has...

    Robin Renzetti has a "series" on "everything is rubber", I'm a strong believer in that, but this latest one amazed me: Robin Renzetti (@robinrenzetti) • Instagram (sorry, don't know how to embed the...

    can't help with particulars, but that swap from binary to ascii makes no sense in this context, also don't torture the source hdd now, leave it be till you're ready to clone it to another mechanical...

    the upside however is the cost of transmission - generally 50Hz will be higher voltage, so for even load on the system the wires can be slightly thinner, this applies to every unit using said voltage...

    these "lego" tents are quite standard in the old world, this is how my old Mikron got delivered, sides disassemble and top is retractable like a curtain, in my case when they loaded the machine up...

    press brake won't work here, there is no support where the bend lines converge so you won't be able to make somewhat precise bend there, pan brake may reach some, but not all bends

    depending on...

    they would be more like modern resettable fuses, they have 2 components in them - a thermal and magnetic, thermal will trip on light/long overload, magnetic will actuate instantly and disconnect the...

    you can't mistake one for the other, resistor rectangle is always skinny with wires coming to the narrow ends, relay rectangle is fat and wires connect to the long sides

    as for the OP, it seems to...
  13. that 12ohm resistance means that the circuit will...

    that 12ohm resistance means that the circuit will draw 2-3 amps, so basically any rectifier that looks like the one on the right will work, in that size they usually start at 25-30A and 200V minimum...

    ok, let's ignore the schematic for now, when you measure 30V AC is on the input side of the rectifier (red wires - "1" and "28V") is there something on the DC output ("F-" and "47")? If there isn't -...
  15. inputs to the rectifier are "1" and "28V" in your...

    inputs to the rectifier are "1" and "28V" in your drawing (the red wires in the picture, and note one of the red wires went somewhere and was cut), measure the AC between those, not against common...

    the circuit wouldn't work the way you drew it, here is something that would if I understood your intention correctly - I don't recognize the element in the green circle, that is a capacitor symbol,...

    has OP given a thought of using belt drive instead of gears? if the right angle input is a necessity, perhaps that could be done before driving the main shaft, twisting the belt might be an option...

    "one size does not fit all", and "not" even in caps, as to suggest the importance of what is being said

    and now I see that it was said completely out of context, so I'll ask - does every topic...
  19. ok, so lets now put your argument in this...

    ok, so lets now put your argument in this particular context - how many of those characteristics useful in 1000A plating rectifier are relevant for a simple dc electromagnet? :) (I'm still assuming...

    afair the difference between these and silicone ones is the efficiency, less voltage drop on the silicone ones, so I don't really see reason why an appropriately rated silicone one wouldn't work for...

    looks like a diode bridge rectifier

    p.s. that particular style is quite old, would be a good idea to replace it with a modern one, since you're cutting wires there already

    wait till you meet a green scientist that wants something made, it is a whole new level :) dealing with engineers will seem trivial after that

    reading more or less recent gearbox drawings can be a handful if you're not very familiar with general layout, I'm not talking about identifying a component or two - but given a drawing, little time,...
