I’m planning to get a bunch of these: 0.56 Inch 7 Seven Segment 4 Digits Red Clock LED Display Common cathode Time 12 Pins. Then I need to figure out how to drive them from an Arduino Nano…
// 2022-09-24 jj5 – actually, these might be better: 0.91 inch OLED Module White/Blue OLED 128X32 OLED LCD LED Display Module 0.91″ IIC Communicate For Arduino ROHS Certification.
I have one of these: SparkFun Tiny AVR Programmer PGM-11801. I was thinking of getting another one or two for backup, but there’s probably no need at the moment.
Also I figured out how to put a programmer on my Pluggable ATTINY Development Board For ATtiny13A/ATtiny25/ATtiny45/ATtiny85 Programming Editor Micro Usb Power Connector (see that link for details).
On my wishlist: Full Feature THETA Robot for BBC micro:bit.
Here are two options for semiconductor analysis:

I found www.ldelectronics.com.au. Might try them out for PCB manufacture.
I think I’m gonna subscribe to Silicon Chip magazine. I’ve ordered the October issue in print format and the September issue in electronic format. Might get a 12 month print & digital subscription starting in January next year.
I found this PDF explaining sample rate considerations: What You Really Need to Know About Sample Rate. It’s mostly about how aliasing works and what you can do about it (employ an anti-aliasing low pass filter or oversample by as much as 10x).
