Pulse Soldering Iron

  1. Cosmetics: “coating PCB with painting in order to prevent short-circuit (anyway youâll be holding device in your hands).”

    Don’t worry, if it not go good, your body act as a ground. No trouble! I am actually scared of this guy: one of the few hackers that I would probably avoid meeting in public. (Images of bare wires going into 120v wall sockets come to mind around now)

  2. Deadfool, all the soldering Irons I’ve worked with aren’t grounded… whats your point? When soldering electronics, you should use a ground strap. Soldering irons are not a source of ground, in fact, can be isolated with transformers.

  3. ok, i am honestly scared now, can we remove this or somthing?

    this is so scary.. it makes me think of the early electronics, you know, paper covered lead wire, all sparking and red hot? like in the movies

    i suddenly feel cold


  4. Hey, my parents house still has some knob and tube wiring in it, and it hasn’t burned down yet :)

    Yeah, neat idea and I might build one because it looks horifying in a good way, but use it for anything important, heck no.

  5. I’m assuming that he either

    A: Forgot to show the ground on schematic

    B: Is an idiot

    All euro outlets are grounded (FOR A GOOD 220v reason), I was also under the impression that most (if not all) european plugs came with the ground connector.

    Heh, I was laughing at all of you freaking out about 120v being ungrounded and not thinking about his 220v connection where he lives.

    But just to freak you out more, when I was REAL young I did pretty much the same thing….and yes, wires will explode in your hands (MYTH CONFIRMED).

  6. frodus, the point of a grounded iron is so that it doesnt build up a charge on the iron. the point of a grounded tip isnt so you dont get shocked or you spark on them its so the iron doesnt. and using an anti static band wont do shit for the iron since 99% of irons are plastic (insulator) handles. so unless you are holding it by the shaft its doesnt help the iron

  7. wow! a dim little light to help you see better.. i wonder what kind of dark little Soviet lab he works in?

    cant say i understand exactly what the chip does in this circet. if 100hz is to high a frequence then he made some mistakes in his memtal arithmatic.

    i dont see what the problem is with the ungrounded tip unless it gets shorted to 220v somehow. realy you could use this for working on live circets.
    also 220v rectified and smoothed looks more like 310v…. i wonder what kind of paint he used? not anything they have in shops in australia!!

    much better that the car building they had yesterday. were was the design download? i wanted to read about how the suspention system was engineered!

  8. zengar: I trust knob+tube better than what came after it. While the insulation may be paper, at least the wires were usually suspended. I’ve seen houses that were built after knob+tube era was over, but still with paper insulation. Difference is, if loose dry plaster and stuff is at the bottom of the wall where the old burnt wire is lying, better chance of that catching fire then a wire suspended in the air, wrapped in old burnt paper. Both are troublesome, but I think knob+tube has some advantages.

  9. Bird603568,

    Good point- and you are correct. Any fet input is bound to be extra sensitive to something like this. However, if you need to solder lugs onto #0 or 2/0 jumper cables, then something this thing comes in handy!

  10. I don’t see how it’s a hack or any sort of innovation.I had my first weller soldering gun when I was 10 and it still works fine. This might have been a breakthrough in the 1930’s but it’s just a dangerous thing to have around now.

  11. I know most of you know this already but.
    Soldering can be used for a lot besides electronics.You can repair glasses and jewelry.I like my soldering gun instead of the iron for anythiung big enough because it heats up so fast.I only use the iron for very small pieces .A propane torch can be used for bigger stuff .You can solder steel with the type of solder they use for car radiators.You have to have the right solder and flux for the right material.For a stronger bond you can move up to brazing ,which requires a hotter gas than propane ,like map gas. For anything stronger you can weld .I’m looking into modifying a 105 amp GM alternator to weld with it. If it works it will save a bunch.
