Topic: What have you made out of old circuit boards? (Read 2 times) previous topic - next topic

I am about to refurbish my clipboard by replacing the old rusty clip mechanism with a shiny new one and I was wondering what other people had made from un-needed PCB's?

My clipboard is made from a circuit board that I laid out in the 70's using the old crepe tape and dot on mylar method that didn't pass incoming QC. It was for a 6809-based data acquisition system. The fuse holder on the clip was a bad idea for a pencil holder that I don't intend to add to the refurb. :)

The inset of the reverse side shows a properly routed "star ground" in the analog section, just for the heck of it since star grounds have bee atopic on this forum. That big 32-pin pattern was for the ADC80 a/d converter. State of the art for the time!  :)

Has anyone else re-purposed old circuit boards?

While working at a used computer store / electronics recycling depot, I covered a wall in the lobby with 600+ used motherboards.  It was pretty sharp (looking).

Sorry.  No pics...

I'l bet that does look pretty cool!

I made a clock out of an old Mac motherboard that happened to have a convenient mounting hole near the center for the clock mechanism's shaft. Kinda hard to read at first glance.

I have not reused old circuit boards.


That's okay! Thanks for checking in.  :)

Just keeping the old post count up, huh?  :D

No, more like an informal survey response.

And you did not even answer the question!

I still kick myself for not buying a core memory panel at a Meadowlands fest back in the mid-80's. I saved my "fest money" (money at a fest is worth more than the same money not at a fest) for what I might see later (we had just gotten in, one often-broken rule was look at everything first then buy), and spent it on something I no longer have while that panel of core would still be hanging on my wall had I bought it.
BTW, core panels are worthy of wall space.

I had these made to see where I could just design circuit boards as jewelry:

I like that. It looks like it might make a good fishing lure, as well.

Really cool westfw! After seeing your creation I was thinking of making a jewelry with some passive components (smd resistors) and edge contacts or make RFID tags on them. You can use them as keys to open garages, doors or secret rooms or something.

I remember seeing one of those when I was much younger but not knowing what it was. Did all of those memory panels have the ferrite beads woven between the wires? I don't remember that aspect of it.

It was fun to touch, watching all those fine wires pop when you rubbed your hand across. *sigh* kids. ;)

The wires go through the hole in each ferrite, doughnuts not beads.

I once had the idea of tiling a wall with old ceramic PGA-package CPUs, with the gold lids on them. I still might, one day.

I like - something like a bunch of transputers, so you could form a simple processor farm, and keep your wall warm!
