IDK, most of the kits require soldering (because the industry is fundamentally braindead) and if you go look at the various online communities, you'll quickly see that this is one hell of a filter.
i'm scared of the magic cancer smoke
Just get the lead free solder and no clean flux, it's much less cancer
is it still magic tho
Oh 100% magic. And SMT hot air soldering is voodoo magic
Yeah lead free solder is perfectly fine.
Where I live, lead solder is even illegal to sell and buy unless you have a permit which is impossible to get for individuals
Interesting, I haven't heard about that.
For systems that...may experience some degree of vacuum...it's common to use lead solder still because it doesn't tin whisker so unfortunately it's still around for some of the stuff I've worked on.
Lead free sucks ass and you can pry my leaded solder from my cold dead hands.
Seriously just wash your hands.
What about the fumes?
Fumes don't contain lead, it's not nearly hot enough. Those fumes are flux burning.
That's good.
But I still don't get why someone would willingly use lead when lead free works great.
I mean the RoHA for example exist for good reason.
Leaded is objectively better for everything except health/pollution. Which is the point of RoHS.
Leaded solder has a lower melting point, flows much better, easier to visually see bad solder joints, and doesn't form whiskers. Also less brittle, so cracked joints are less likely.
Sure but it works well enough if you have just a little skill.
Or just use an extractor.
Yeah that's the real answer...
We were taught that at high school....
Same here, but I'd still be pretty annoyed if I had to do it to put together a drone, it's a pain in the ass.
I find it interesting more than anything else.
In high school electronics we also used a tesla coil (that can kill you if you touch the wrong place) so they disconnected the mains cord so it had to be rewired prior to use to keep us safer.
They taught us how to wire plugs the following week...
You got taught how to rewire a plug in high school?
Middle school for me. Was about a month of machine shop. We built a breadboard, demonstrated the difference between series and parallel using light bulbs, that kind of thing.
Did half the class also make tazers after learning what a capacitor does, which wasn't three best thing to know with wooden desks....
Nah, purely resistive loads in that class. Was pretty basic since it was a required course. Electronics in high school, an elective... yeah there were some dipshits that earned the Sparky nickname.
Now tech school, where we were left unsupervised for lunch... yeah there were a lot of blown out voltage regulators from using our hand-built power supplies to pop capacitors in various ways and degrees of safety. What can I say, some guys just love the smell of burnt peanut butter.
Did you also have the group that had competition to see who could hold hot glue the longest, wacked eachother with metal rulers held over bunsen burners, and snorted citric acid when you made sherbert?
I had some of those in my school too...
If those kinds of things happened I wasn't around to see it.
Did have a guy do some embroidery on his palm during sewing class though (we got the kitchen sink thrown at us in middle school, was actually kind of neat). Same guy intentionally turned the oven up to max while making pretzels in home ec. Not the brightest bulb.
I must have got the crazy science ones while you got the crazy home ec - worst we did in home ec was accidentally turn the whipped cream into butter... oh, and made a rum (flavoured) and rasin ice cream.
Yup. Was told clearly at the start to not plug it in to the wall sockets located just underneath us.
Soldering is so easy.
Yhe worst part of soldering is losing your soldering iron every 7 years between the times you need it.
One of my many hobbies is electronics and messing with electronic instruments so I use mine fairly often.
