Success, except for mixing up the position of two different colored LEDs. Ah well, at least it still worked. Will need to pick up some solder wick next time, couldn't remove a small but significant amount of solder from the incorrectly soldered LED(s). And one LED wasn't working...
Pardon this newb here going all hooha over soldering, but it's a new thing to me. It felt like brain surgery, you gotta keep a steady hand when feeding the solder wire to the iron. Oh, and the melted solder, LIQUID METAL!!!
I think I was supposed to have done soldering in Living Skills (Kemahiran Hidup) aeons ago, but being the lazy student I was(WAS!), I skipped class and left the solder parts in its packing collecting dust in some obscure corner of my room. I certainly regret throwing the whole packet away, now I have to buy them with mah own dough.
The ugly, and amateurishly soldered back of the circuit.
It's a flip-flop circuit, whatever that is. While I recognize the components, I have no idea how a bunch of resistors and a couple of capacitors & transistors work together. The LEDs form a heart shape and blinks. Need to redo another set to display in my car and room door. And, also understand what & how a flip-flop circuit works.
What I learned:
- Tie up hair - My soldering iron has severely burnt hair on it.
- Ventilation - I hadn't realized this until I left and re-entered my air-conditioned room, naturally it reeked of solder fumes.
- Wet sponge and thinning the solder iron
- Clear/Neat table - Bro very nearly touched the hot solder iron. *gasp*
