I'm building a LED cube, and the LED pins are the framework and the circuitry.
I need to solder the end of one LED-pin to the next LED-pin right near the LED-body. I am new to this and just bought the soldering iron - its an OK one with temp dial and station. But in your experience, how do I get that NASA quality solder joint while I hold the solder, the soldering iron and have the components rolling around on the desk and possibly overheating. Is there something I don't know?
