Well, I promised lightheartedly to post something the other day...
This here is a "Beta Version", I should appreciate any comments..
There are very good reasons why I choose any of those parts, but it would now need to many lines to explain that in detail :sunglasses:

This is the set of parts I should recommend for an aspiring hobby electronics

Very much depends on your scope of electronics. It will look quiete different if you are interested in HF, or in high voltage applications....

Resistors
each 100 pcs: 220 - 470 - 1k - 2k2 - 10k - 22k - 100k
each 20 pcs: 100 - 220k - 1M
if you want to be perfect, also 20 pcs of: 330 - 4k7 - 47k

You might need more specific values in these cases:

  • To exactly match brightness of different colored LEDs.
  • To set up a specific voltage with adjustable voltage regulators as LM317.
  • To setup fine tuned low pass or high pass filters
    For all this there are no recommended values to keep in store...

Take metal resistors, the are generally light blue rather than orange with 4 stripes on it (abc + d zeroes)

Pots
There are fine models from ALPS (RK06) that also fit into breadboards
5x 10k
5x 100k

Diodes
20x 1N4004
20x 1N4148
10x 1N5818 (Schottky)
10x Zener Diodes 5.1 Volts 0.5W
10x Zener Diodes 3.3 Volts 0.5W
You migh not need the Zeners, but they do not costso much....

Transistors
100x BC 337 or BC 547 or 2N3904 (NPN)
20x BC 327 or BC 557 or 2N3906 (PNP)
10x Power N-FET (logic level, 50V, 10A) as IRLIZ34N or similar

(I now say "5" as a compromise..)
Opamps
5xLM324

Voltage regulators
5xLM317
5xLM2940 or similar

Logic Chips
5x 74HC4093 (4xNAND with Schmitt Trigger input)
5x 74HC06 (6xInverter with OC output)
5x 74HC4016 (6x Inverter with high voltage input)
5x 74HC42 4:10 decoder
5x 74HC166 (PISO)
5x 74HC595 (SIPO)
5x 74HC295 (3:8 decoder/latch)
5x 74HC4040 (12 fold frequency divider)
5x ULN 2803 (low side driver)

3xPort Expander for I2C bus PCF 8574
3xAnalog Multiplexer 4051
3xAnalog Switch 4066

Caps
You might want some 22p if you want to make own AVR boards
Otherwise:
each 20 of: 1n - 10n - 100n - 470n (Ceramics, 60 volts)
each 10 of electrolytes (25 or 30 volts rating): 4u7 - 47u - 470u

Chrystals (Just to have them... HCU49U)
2x 12 MHz
4x 16 MHz
2x 20 Mhz

Oscillator
2x 1 MHz
2x 16 MHz

Coils/Inductors
