Purchasing parts and basic components for a new lab

A wide variety of projects in mind (I'm mostly in this to learn, experiment, tinker, etc), so not any one thing in particular.

Or these protoboards? https://www.amazon.com/AUSTOR-Prototype-Universal-Protoboard-Electronic/dp/B074X2GDH2

It’s really a pain that you keep making more threads, since the advice you’ve already been given on these items isn’t visible to those posting now.
Those are exactly the kind of protoboards I meant, and that’s a great price. :-+
I already told you how to get the 3M breadboards for a fraction of the normal price, by ordering them directly from Assembly Specialist (their actual manufacturer). You talk about not wanting to have to rebuy, and then cheap out on the ONE item where everyone unanimously agrees you shouldn’t skimp... :palm:
DuPont jumpers: those are what I meant. IMHO, buy 5 sets of each kind. You can’t have enough of them as they get occupied with projects that are stuck halfway.
Skip the zener assortment. Maybe pick up a 5ish-volt zener to play with and learn how they work. But you won’t reallt need them much.
Resistors: I’d get one or two of the 300 piece sets, and then also order a bunch of extra 1K and 10K resistors, somehow I find I use tons more of them than other values. (And also some extra 220 and 330 ohm, since those are what you use to run LEDs off of 3.3 and 5V.)
I’d also pick up some basic opamps to play with. I suggest some 741, NE5532, and either TL072 or 082.
The CD4017 decade counter is also a great fun beginner chip (e.g. chasing LEDs).
And of course some classic 555 timers.
All those ICs, together with the resistors and caps you’ve listed, and LEDs, make for some great learning and fun.

I did look at those 3M boards on the AS site, but there so many variants and types that I got overwhelmed without knowing more and lost track of it. Unless I missed a comment somewhere, is the SS252 what you were referencing? Edit: However the shipping charges on the AS site are steep -- price is lower to get the 3M board on ebay in this case.
I'll check out those other components too -- thanks
741: Unsure of this one as of yet... lots of variants.
NE552 I think: https://www.ebay.com/itm/10-x-NE5532-5532-Dual-Low-Noise-Op-Amp-IC-Texas-Brand-USA-SELLER-Free-Shipping/223015694297
TL072: https://www.ebay.com/itm/10-x-TL072-LOW-NOISE-J-FET-DUAL-OP-AMP-IC-USA-Seller-Free-Shipping/323271252084
CD4017 decade counter: https://www.ebay.com/itm/10-x-CD4017-4017-DECADE-COUNTER-DIVIDER-IC-TEXAS-BRAND-USA-SELLER-Free-Shipping/323161690070
555 timers: https://www.ebay.com/itm/50PCS-NE555P-NE555-NE555N-DIP-8-SINGLE-BIPOLAR-TIMERS-IC-US-SHIPPING-M175/113156855492
T3sl4co1l:
Zener assortment is fine, though I find I don't use many, personally. 1N52xx may be better (1/2 vs. 1W) if you'll be using them more for signal clamping than shunt regulating (less capacitance). 3.3, 5.1, 6.2, 9.0, 12 and 15V values are probably must-haves. You can always boost a smaller zener with a power transistor if you need more.
Speaking of references, TL431 definitely, and LM4040 or family if you need more precision.
