Sorry for my late response, I had some internet issues.
Thanks for your help, I now have a more clear view of what to get. The posts linked by mariush have informations interesting to make your decision. Sorry I haven't found them with the search function (and so mariush keep linking them again and again, facepalm).
I must have defined what I plan to do. I'm a computer engineer and some months ago, I came across a conf talk about Arduino. Arduino is way more simple to get to µController programming than 20 years ago (and way cheaper btw). That made want to come back to electronics. Budget is not much of an issue in my case because I'm a freelance and thanks to the Internet of Things buzz, I can now justify that my electronics spendings are for my R&D.
So I want mostly to do circuits around arduino programming (and PIC, STM32 in the future). My current plan is to do :
- a small, cheap function generator (I don't intend to do RF)
- a weather station with zingbee outdoor modules
- a reflow convection oven with PID and the PWM with zero-crossing detection to drive a solid state relay
- µControlled power strip for Raspberry Pi cluster with power monitoring and start/stop control
- converting a CD jukebox to a BluRay data jukebox
- CMS resistor decade (that's the easy one in my list)
- µPower Supply if Dave advance on this one
But I also want to experiment with analog things because that will be needed if I want to use sensors and don't want to be limited to arduino sensors boards. That's why I asked for generic AOP and such, to do some breadboard experiments to learn how to use them. And that is also IMHO the way to learn electronics and not just plug things in an arduino socket.
And for that, I needed PTH component to put on a breadboard. But when I'll get to the point of baking my own board, I want to use CMS components, because they are prettier and I want to learn other things that those I have already done as a teenager. So if I need a specific component, I'll buy several of them as CMS and use adaptor boards to use them on a breadboard.
I bought a set of ~1000 different CMS components from ebay with lots of 74HC as well as some other things like RS232 chips, EEPROM, ... That was probably a surplus from a military or medical project because there some components refs pointed to non ROHS versions and the resistors were 0,5% precision (5 differents values measured between 0,1% and 0,25%). Other analog IC I got in this set are rather for specialized use like the TLC2264IRD. And I prefer to use them later when I know when they will be worth it rather than frying them for free. So on the digital side, I have much of all I would want in CMS and will use adaptor board for them if I need them.
In conclusion, I need only a limited set of analog basic PTH components to start.
I finally came to this list :
Diode1N4007 : not necessary to bother with previous 1N400x versions and it could also be used to make a diode gate
1N4148 : for signal use
BAT43
A kit of zener Zeners
A kit of LEDs
BJT Transistor2N2222 : preferred over BC337 as it seem to have a better spec
2N2907 : its PNP friend
MOSFET TransistorBS270
JFET Transistor2N7002 : I took the cheapest one available, just to have a JFET to toy with
ComparatorLM339
AOPLM324
ICsNE555
74HC595
Power supply7803, 7805, 7812 and 7912
LM317
Thanks all for your help.
