What can I do with 400 555s?

[texaspyro]

Any ideas what to do with 30,000 2N7000's.   Got 12 reels of 3000 pieces from the same place / price as the 555's.  Sold a couple of reels...

30,000 units? WOW! You may try to further sell them.

If more people jump in with all of their inventory overages, you can join forces and build something truly spectacular or downright scary.

At those prices those 555s and 2N7000 are hardly worth re-selling.  The shipping costs more than the goods.

But it gives me a good idea for a similar firefly project.
I've got over a hundred 18650 cells that I have reclaimed from discarded laptop batteries.

I can create a small PC board with all the components and a couple of 18650 cells.
And put them into one of these plastic boxes.  Then have some "firefly building-blocks".

Order another 155 555s, so you'll then have exactly 555 555s! 

Hahahah... almost worth spending USD 8 for that

Stocking stuffers for 19 of your friends. I'm assuming you still want the first 20 for yourself.

If I do that this year, I won't have any friends the year after

Time to make new friends!

When your done with that let me know what to do with 2.5 pounds of Neon Lamps (NE2)…

Maybe try some surplus dealers?

Also, as has been suggested, schools.

I am sure many of us would take some if postage did not cost more than getting them direct from China.

A lot of us have stocks of things we have no use for but do not know how to put to good use.

BTW, I purchased a dozen 555s last week to try out some of these ideas along with a few of the basics.

I think I would have to try this when the wife is out. I can imagine her reaction to the noise...

Jayeye:"What can I do with 400 555s?"

A Class D bridge tied load stereo amplifier: 15W per channel into 4 ohm load could use 84 of them

Lineup per channel:  One 555 as triangle wave generator, one as comparator (low Z audio in to CV pin) to generate a PWM then 20 as inverting buffers, and 20 as non-inverting buffers, with current sharing resistors in series with each output to combine them into a pair of inverted and non-inverted PWM outputs good for >3A.

Combine that with 2x RoGeorge's suggested 'Synth' and you are up to 90 555's used,   Build four units for the kids of your least favourite colleagues or ex-friends and you'll be universally hated by their parents, and *still* have 40 555's left for your own stock.

That was a hoot of a noise maker!

You could give them to me

NE-2 lamps are great for nightlights, relaxation oscillators, trigger tubes, and all sorts of applications where an LED is too boring.

This is the answer to the neons question:

[james_s]

That's awesome, I wonder if those are standard NE-2's though or trigger tubes? A while back a friend of mine played with a NE-2 based ring counter and found it to be a bit fiddly. Ambient light levels would affect triggering and the characteristics changed as the lamps aged. It's possible that carefully designed it would work well.
