I want to build robots but have to many problems
#1 I dont know how to build robots
#2 I dont know where to find out
#3 I dont have the budget
# my soldering iron is caked with a black powder and won't melt the solder I sanded it off but it came back as soon as it gets hotenugh
including making lists
1. You can learn how to build robots by clicking on the Start Here link at the top of the website. The excellent walthrough doesn’t explain WHY but it explains HOW.
2. See #1.
3. I would suggest employment of some sort.
# - Try tinning your soldering iron as soon as it is hot enough to melt solder. If that doesn’t work, get a new one.
Before I bought a coldheat
Before I bought a coldheat soldering iron I always melted a small bit of solder on my soldering iron after use. That way if it was months before I used it again it looked clean. Next time I used it I heated it up and wiped it off with a damp sponge. This keeps it clean and rust free.
Are those coldheat cordless
Are those coldheat cordless irons any good? A friend of mine told me they were crap and never got hot enough, I thought I’d get a second opinion.
Keeping the tip clean is defiantly key and realize you don’t have to buy a new iron in most cases you can just get a replacement tip, usually only about $3. Get some steel wool… Thin solde… and some flux…
I think it’s awesome that your only 12 years old, that’s what 7th grade right? Same age I was when I got into electronics. Look at me six years later and I’m still just getting started, real classes start next spring and I can’t wait!!!
Oh and you don’t need much money. At first start small, tare apart broken things like VCRs, radios, garden lights, Ext… take out all the parts and see what they can do. If there are any thrift stores around have your mother take you there, buy some old RC cars, computer mice, power cables, printers, maybe not that exact stuff but I think you get the picture. Remember It’s good to experiment, as long as it doesn’t involve high voltages, or your mother’s $200 Kitchen Aid…
Anything you want to know is online you just have to look for it. An area iv been slacking in lately, but none the less its true.
Anymore questions feel free to ask. I know i’m willing to help in any way i can.
Question, what have you made so far? Just wondering if you have hacked some old toys or anything.
Good luck

My dad has one, and he says its crap and that it doesn’t get hot enough.
2nd Opinion
They are crap.
I do soldering with an 80 watt gun - so i have no patience for them
That’s Right!
That’s Right! I also use a 1000 Watt Gun to both solder and hunt. So no patience for a coldheat iron. Can’t kill a deer with that…
Dang !
It’s time I upgrade
