You know it’s not appropriate to search your parts for electronics project like what would you do when you buy food from market. You always find that the local market is not sufficient and many parts are scarce. So I would say to buy on electronic store on internet.
One thing I like from buying from local market is you can touch and actually see the size. There are many e-store included photos but rarely gize you the actual size. Another thing you hand carry it, no waiting time.
Well I like to challenge myself. How if I can build my electronics based on local market stock. The answer it’s not a beautiful experience, it’s like roller coaster ride. And you will find yourself dumb cause you always can open your laptop and smartphone to purchase via e-store.
