Do i need to go to some technical college to learn fabrication?
Are there other ways.
Specifically for the basics like soldering etc.
YouTube is a good place look.
Lots of tutorials around. example:
Ask in the forums when you come to a situation where you need some instruction.
Look at "instructables"
Start fabricating! Yes really! some things are learnt only by doing them! I am a mechanical engineer and have studied fabrication for 4 years but believe me! experimenting with things, playing on field, trial and error methods, frying up components is the best teacher!
In my opinion, grab a solder, wire, some components and start playing!
