×1
panasonic two-lead tactile switch
×6
Generic SPI OLED, SSD1306
ANY OLED, as long as they have the SSD1306 driver, and have SPI interface, will be good. However, not all of them might be able to fit directly onto the board.

DPDT sideways pushbutton
DPDT is the one you are looking for here. Being thru-hole mounted on a PCB, other ones will work, as long as they fit.
×1
SSD1306 128x64 SPI OLED
ANY OLED display, as long as they have the SSD1306 driver, and have SPI interface, will be good. However, not all of them might be able to fit directly onto the board.
×1
Panasonic tactile switch
Quite a lot of quality buttons out there. Pick the one you prefer,

6-pin Header & Gender Changer (5-pack)
Digilent 6-pin Header & Gender Changer (5-pack)
Common pin headers. You need QUITE a number of those.
×2
LED (generic)
LED (generic)
Both 3mms and 5mms work. However, if using three 5mm LEDs, not all of them might fit comfortably.
×3
Buzzer
Buzzer
Non-continuous buzzers are what we need. However, not all buzzers might be able to fit onto the board.
×1
Vishay sb240 diode
I used the SB240 because I didn't find the SB220. They are mostly identical.

For thru-hole, anything that can melt solder is sufficient. However if it is the surface mount MAX1811 then I recommend something with a bit more precision.

Typical college student. I started soldering since grade 7. I still don't have a solder station, but I don't do TSSOPs ... YET
