This short and easy instructable shows how (and why!) you tin the tip of the soldering iron.
Never soldered before? Here’s where to start.

Last week I decided to make a USB powered flashlight.
While I know a lot about computers, I’m pretty much a solder newbie.

This was a problem.

Luckily, though, I work with a formerly-NASA-micro-soldering-certified technician and soldering instructor.
Yesterday, he instructed me as I soldered together my lovely little flashlight.

My newbie perspective is useful as I won’t overlook any "obvious" things that more experienced solderers might.
And my knowledgable overseer (Thanks Terry!) taught me the proper methods, so you can do things the right way too.

You will need:
water
solder
A soldering iron

If you can’t get a soldering iron with a digital temp readout (and I can’t) get a soldering iron with a temperature dial. You’ll be glad you did in the long run.
