Box of ICs (>50)

19135; $10.00

81 ICs.

7/10 Nice variety! Website says "more than 50", so I may have gotten lucky. I now own so many 555 equivalents I fee obliged to post more comments on the hackaday blog.

Semiconductor Treasure (50)

15287; $5.00

52 Semiconductor Items.

7/10 Pretty good selection.

RCA Replacement Part Assortment (10; random!)

19894; $2.00

10 labeled bags.

9/10 Fun—there's many unique parts in these, and the price is OK too.

Linear ICs (15)

61; $2.49

15 ICs.

7/10: Decent value, but too many op-amps.

Super Diode Assortment (>200)

4006; $2.00

The packaging wasn't great, but they, uh, are diodes.

5/10 needs better packaging.

Super LED Blowout (80)

43; $2.49

Yep, these are LEDs!

Some of the small red ones were broken, they're at the right top/center in the picture.

8/10 Quite a lot of "special" LEDs, but too many of the small ones. Boring!

Bargraph/LED Bar Displays (8)

47; $2.49

4/10 This assortment was not worth it. I'd get "Unique LEDs" instead—same price and (from my experience) more stuff!

Unique LEDs (15)

36; $2.49

8/10 A better bang for your buck than "Bargraph/LED Bar Displays".

Super DIP Switch Assortment (5)

14340; $0.99

9/10 Decent price, nice and clicky. They're DIP switches.

Super Box of Electrolytic Capacitors (> 100)

20174; $2.95

I'm not a capacitor expert, so I don't know what quality these are. The green ones on top are nichicon branded, the blue ones on the bottom are eulogy branded.

8/10 Great value, but it would have been nice to see a larger variety.

Super Switch Assortment

16652; $1.90

These people really love the word "Super"!

9/10 Nice variety. Would have loved a big red button, but whatever.

Part Mixture 3 (50)

26; $2.49

A bit of a "grab bag".

7/10 Can't really complain, would have loved to see some more interesting components.

SMD Mixture (50)

29; $2.49

2/10 Not worth it. The components are mostly resistors, which are worth next to nothing in the SMD world. Get some nice SMD Resistor/Capacitor assortments on eBay instead!

IC Sockets (20)

28; $2.49

9/10 All the important DIP sizes and some nice SMD ones too. Yay! Square SMD sockets would be more useful though ;)

Thanks for reading. If you enjoyed it, please consider following me?

Thanks for sharing the 'teardown' on the Goldmine assortments!

MC1355 is an old FM IF limiting amplifier, if memory serves. Used to use them in FM car radios. About 70dB of gain at 10.7 MHz, balanced input and output.  Output can drive a ratio detector or FM discriminator coil to demod the FM audio. There's a built-in zener across the supply terminals, so be sure to feed it through a series resistor otherwise you'll let the smoke out...

you should get the giant suprise box next time.

alpha_ninja wrote 08/04/2015 at 06:46 • point

I'll keep that in mind! (For future reference, the items are G2200 and G9321)

Edit: I just watched a youtube video about these. They look amazing!

  Are you sure? yes | no

2 Surprise boxes and another 2 IC boxes are on their way :D
