Ok, don't file your tip, your choice....@ $3 ea. I can do this abt 15 times, see what I'm doing, better heat & solder control and not ruin SMD parts, expensive boards or spend countless hrs fixing what the blob did. The SMD parts on these huge compared to what I'm used to soldering, but I wind actuators with .001 enameled wire too.
I said to re tin immediately, nothing abt wiping a tip clean.


TJ, I was always trained to keep one hand in your back pocket with HV. To easy to forget and rest that free hand to a common ground completing a deadly circuit. Last cap I saw that big had a PCB sticker on the side. lol

I have an old oak liquor crate, a couple of glass insulators, and some thick copper tubing. I even have a big ~1930s knife edge switch. All I need is the juice.

so would an old tv/pc monitor tube make a nice 30kv(+?) cap? tho i'd be scared to use it, wonder what farad there rated at, dont think im gonna stick that on me DMM hehe unless i need some smoke for me laser , also got a nice flyback transformer too.

That "mad skill" is helped a lot from the huge amount of soldering fluxant that he place on the pads and pins

Main purpose of the fluxant is right that one, to avoid that "solder bridges" can be formed between near pins, other than improve soldering and take care about oxydes

Default Re: Electronics Tips

If you notice the "hoof tip" is tapered and cupped underneath. The tapering allows better precision and the "cup" naturally wants to stay full of solder. The melted solder "ball" is formed in it due to atmospheric pressure much like a rain drop. So, melted solder wants to flow to it and "ball up". Melted solder will try to stay equally on a soldering tip. If there are voids, it will fill them. If there are none, it will flow back to try and cover the tip till gravity causes the excess to hang down actually pulling excess solder away from the joint. 60* tips aren't made for precision work. The sharp angle causes excess solder to be facing the joint now hanging waiting to drop.

I built one a few years ago using a car ignition coil. I had one laying around from an old V8, I replaced the coil in the car just because it was 25 years old. The old unit sings nicely in the ladder! I'll take a video later and share. I have been meaning to fire it up for a while now... TIP: do not run jacobs laders anywhere near computers!!!

Ooooh. How much for the knife switch?

Why not add an old school (real old) gas valve knob, do the whole Dr Steel/Steampunk look....
