You asked for it, and now you’ve got it. It’s taken more than a decade of accumulated complaining, but this gigantic 555 timer IC has finally gathered enough psychokinetic energy to take corporeal form and demand fealty from the readers of Hackaday.
Or not. The less exciting explanation is that creator [Rudraksha Vegad] was looking for a way to combine his interests in discrete electronic components and woodworking. The result is an incredible build that’s more than just a conversation starter; this desktop-sized version of the iconic integrated timer circuit is fully functional. You can even hook it up to a breadboard, assuming you’ve got some alligator clips handy.
Lifting the lid on this wooden “chip” uncovers an intricate hand-wired array of discrete components that stand in for the microscopic goings on inside the real thing. He’s even gone through the trouble of recreating the symbols for the comparators and flip-flops that you’d see in a diagram of a 555 using wooden shapes to elevate their respective components. It might not fit the classical definition, but surely this must count as some form of circuit sculpture.
[Rudraksha] credits several other projects for not just inspiring him to create his own mega 555, but for helping him wrap his head around the internal workings of everyone’s favorite IC. Using components he salvaged from old hardware, he says the project ended up being very educational for him. These days, when most makers are more likely to reach for a microcontroller than a logic chip, spending some quality time with transistors and passives can be quite illuminating.
Eh can be done with a single 555 timer…
+1
A 555 +1 ?
Do you mean a 556?
B^)
What does B circumflex closing parenthesis mean?
He slipped and accidentally pressed B. Then cat got startled, her paw hit the Shift and her head hit the 6. Beer glass strategically placed nearby was overturned, hit Shift again, and then shorted the key ). Few milliseconds after, Enter key was shorted as well … RIP keyboard formerly known as Ren’s.
That is a sideways face.

[Miroslav] Thanks for the chuckle!
It is an SQL injection string ;^)
Or put an Arduino inside of it. Or sized up the acceptable voltage given the size.
Better done with a cheap microcontroller.
You missed the point.
Or perhaps you did.
Sorry your time(r) is up, you’ll have to leave the internet now
It might be before your time here at Hackaday [Tom Nardi],
but HaD previously blogged a large coffee table in the form of (IIRC) an 8 pin DIP.
But, I don’t think it was electronically functional.
That would be this one:

But large scale functional ones have been done as well:

I was probably thinking of this one:

This 555 won’t be functional either if someone spills their coffee!
Lifting the lid on this wooden “chip” uncovers…
Don’t you mean “decapping”?
I think it would be neat to have a clear plastic cover as well….
I don’t have anything like the skills this took, but would really like to see a gigantic working model of the LM3909 Flasher/Oscillator chip as a similar project…
Should have cut a 556 in two…
In chich plane/orientation ?
Whichever.
Chichever
FTFY!
…wat
what Jace said
it’s a numerology bot with a mission
> You can even hook it up to a breadboard, assuming you’ve got some alligator clips handy.
Quite… it woooden fit a DIP-8 socket…
I hoped it would be electromechanical
I’ll stick with my worship of obsolete electronic components. 555, LM741, CD4049, etc.
All hail our 555 overlord! Or was that overload?
That’s how we know it’s full of magic smoke.
That would be 000 if you read the three digits from the color code.
Finally ! Someone made a better footstool !!!

This is beautiful.
Who remembers https://www.youtube.com/watch?v=bjAlzA4Cyys ?
Interesting, but no longer the largest?
B^)
Brilliant! Love seeing my old friend from the 70s alive and well!
Maybe a hydraulic version in the same size package?
Tilt your head to the left and see a smiling person with glasses and a pointy nose.
Let me know when it has Doom ported to it…
Surely the right way to do this is this hack:

followed by this one:

Who is up for making a walking 555?
https://www.diywalkers.com/mechanical-spider.html
What about implementing one with 12AX7 double triodes?
Awesome Excwllnt
Cool. Now do an ATtiny from discretes..
