whether should i stock up on from website or not ?

[chris martin]

Hello, everyone,

  recently, i have been interested in  hobby electronics. i thought that one day i would become a professors or started my own career out of this. to tell you the truth, there is an electronics surplus store that i get some necessary components but it always takes me 2hours.the reason why the price is so cheap is that the store owner has developed a website furthermore,its website has done SEO(ww.shanghaiseo.com), it rank first, so its deal is very big, the sales volum is mainly from website, the outside of website, boss advocate wholesale. so there are many shelves full of trays with other things i want. i wonder what components are the most used? what should i stock up on from its store outside website or buy the components from website? What ranges of Capacitors, Resistors, Diodes, and Inductors would I be using the most starting out in electronics?

 

Are there any other components I should get while am at it? ICs, Transistors, Relays, Motors, etc? I want to get into Radio and Robotics once I get a grasp on the basics.

 

Thanks for any and all help

I suggest you to instead of buying components in bulk first you study some circuits that you can understand and make list of them. then you buy components required in that circuits.
Commonly used transistors are BC547,557.
ICs are 555,4017,4011

Hi Chris,

 

I used to shift my place quite often and where ever I go, I set up a kind of small electronics lab in my room. The components I used to purchase from the nearby store are as follows;

 

RESISTORS:

10 ohm, 100 ohm, 330 ohm, 470 ohm, 1K, 5.5K, 10K, 47K, 100K, 470K, 1M

 

POTENTIOMETERS:

100 ohm, 1K, 10K, 100K, 1M

 

CAPACITORS:

0.01uF, 0.1uF, 1uF, 4.7uF, 10uF, 22uF, 47uF, 100uF, 330uF, 1000uF

 

DIODE:

1N4007, 1N4148

 

TRANSISTORS:

BC548, BC558, SL100, SK100, BC107

 

ICs

LM555, CD4017, LM358, LM741, ULN2004 etc.

 

Hope this is what you were looking for.
