Doing basic beginners kit, going great, lots of fun. Beginner's kit, beginner's mistakes.
I put in a 16 pin IC "Chip" i guesss, is it a chip? upside down. Is this a problem? It is notched to go a certain way, but all I see are metal points. Damn, I see integrated circuit, so it's all messed up. So... I can't get the solder braid working to take off all my solder, and I don't have a solder pump, and I really wanna finish this. Can I leave it? I did discover that wrenching at it with pliers won't get it out. Dios Mio! Can anyone help? -
Hey, still new to this. Interested in SMT/SMD. How exactly would I go about doing this? Syringe + heatgun?

Left column is how the part is labeled in Schematic. Correct? IC1 = Integrated Circuit 1. C1 = Capacitor 1. No? What does C usually mean, what does IC usually mean? R? B? D? Q?
Right column:
For instance, LED1 CQX35A. What could CQX35A possibly mean? A model number, from where?
R6 3k3 What? 3,003 resistor? I mean, I'm so lost. Are these all common parts?
What are standard symbols for schematics, what do they mean?
How am I supposed to attach these all? PCB? Am I going to have to make my own from a PCB site? How will I get the spacing right? Can I use a "universal" pcb. Breadboard obviously isn't practical. Should I just use pieces of wire. How will I know if the wire is correctly rated? Or a toggle switch. How will I know the compatibility of things? I want to learn it all. I just need some direction. I have 2 learning kits coming in the mail. Real basic stuff to try and learn some solder technique. I have a cheap radio shack iron. I don't think it's chisel typed, unfortunately. How important is that? And I'm still unclear about how to solder. From what I understand. I should tin my iron, then put it on one side of the lead (leed? sp) then touch my solder to it till the flux runs, then move it around the edge of the lead/leed. -
Trying to do a beginner project. I'd like to do something cool.
Example: http://www.electronics-lab.com/projects/models/008/index.html
Would that be too hard? I'll admit I'm confused by the parts list on all of the projects. But with some guidance, I think I could figure it out... no?
IC upside down?

1000 Watt Heat gun, on high mode. IC fell out! I finished the kit. Great fun. I'm going to do another tonight. I'll try and find more over the weekend. Where do they retail?
