Now that's a long list!
104 ICs—that's 52 per box.
8/10: This one was definitely worth it. Although there were fewer ICs in the boxes this time, there was a better variety, and another reason for this was probably the larger chips—less DIP-8s and more of those super-wide, crazy ones.
2x Super Electronic Surprise Box
9321; $7.95 each
SO.
MANY.
CAPACITORS.
If a component isn’t listed here, it’s probably a capacitor.
Also:
- masses of resistors
- those small, dark blue ones that there’s a ton of on the first picture have values 1071Ω and 7321Ω
- the big, light blue ones are all pre-bent and 100Ω
- two sandstone resistors
- some random resistors
- crazy amounts of diodes
- some weird-looking ferrites?
- a lamp base with wires—I’m sure some cool mesh-networking thing could be made with these :D
- a speaker!
- two stereo RCA connectors
- two rectifiers
- some switches
- those black switches (DPST) have a nice insulation between the two sides
- springs!
- springy!
- LEDs!
- glowy!
- A hex nut
- A potentiometer
- A speaker with some weird connector
- Some SMD inductors
Box 2!
Again, many capacitors.
Also:
- A zip-tie—A true marvel of modern electronics.
- lots more of those weird ferries
- some more of those weird-valued resistors
- a few more of those 100Ω resistors
- some more random resistors
- SMD sockets
- 3 more RCA jacks (these are a different type)
- some more SMD inductors
- 2 more potentiometers
- more springs!
- even springier!
- more LEDs!
- even glowier!
- crazy amounts of those black DPST switches
- some form of wire connector
- You can remove the orange part, insert wires, push it back in and the two wires are connected. Not sure how else to describe these.
- some kind of electromechanical valve
- some plastic mounting parts?
- That static-resistant bag.
- This thing is amazing. There’s 500pcs of HLMP-6400 (small, yellow through-hole LEDs with pre-bent leads) inside.
- I’ll have to make something cool with these. Suggestions are welcome!

8/10: Both these boxes were great.
However, there's an important piece of advice I need to give you:
Don't order these by themselves, and don't order more than one.
It's obvious that the contents of these change from week to week, so it's not worth buying too many at once—consider them an add-on to whatever you're buying (albeit one that is quite heavy and drives up the shipping cost by a few dollars)
Thanks for reading!
