So apparently in 1993, Avon (the MLM (not that MLM (or that kind either))) commissioned a Soft Foam Telephone.

There are some ceramic caps on here too, but I didn't desolder or test any of those. I don't think I really need to? unless you fry them by overvoltage/overcurrent I'm not sure they're gonna die anytime soon.
-
@foone sounds like somebody's getting a (working) christmas present!
-
I also don't know if this thing ever worked: this one came from ebay apparently unopened over the last 32 years

@foone ceramics almost always hold up, I wouldn’t bother.
That brown goop looks like a particular glue which is known to become corrosive and conducive over time. But if it’s that, why also hot glue? I has a confusion.
-
It's entirely possible it never worked, and they soldered it together wrong

@moira fortunately there's no traces there (since it's single sided) so that shouldn't cause problems
-
@ArthurBarbaro it's a pdf doing font weirdness, not html
-
@diedofheartbreak nah, it's got no way to hang it up, so they made it a on/off switch
-
So the current plan is:
1. Stick new caps on
2. Test
3. If not work, start yanking components and documenting what they are until I run out of components or find some that are broken -
@foone who been eatin chocolate

@lritter not me! I'm diabetic. some 1992 punk probably was, though
-
@foone I feel like there was a missed opportunity to make it completely yellow and call it Banana Phoam
-
@huronbikes they sold this in a lot of varieties (the phone part is the same, they just need to make new foam cases for each license), so it wouldn't surprise me if they did!
-
@foone yea MLCCs don't really die. You can regenerate them by heating them up, might be worth a try if its that old but unless its precision caps for some analog function I wouldn't suspect them to make the pass or fail difference.
-
@timonsku yeah. I'm not gonna worry about them unless I can rule out everything else.
-
@foone I can smell this pcb from here
-
@mattsains I can't and it's on my desk! I'm anosmic
-
@foone This particular style of PCB routing seems to be common among really cheap single-layer PCBs. I've been wondering, is there any practical reason for it or is the result of a particular layout software?
-
@karotte this one might be old enough that they routed it by hand with stencils.
-
@foone These kinds of boards were usually done using wave soldering.
