No reason a car can't still be on the road 100 years after manufacture

At what point is it no longer the same car if you’ve replaced all the parts ;)


Tuning into time radio signals like DCF77?


Apparently the Force Majeure section of the deal is very weak, so if there's the slightest upset, they get out of that.



The temperature stability looks fantastic, but it has a voltage coefficient for capacitance which is worse than film caps.

From datasheet:

> Voltage <-0.1%/Volt

That is significant: over just a 10V swing, it could be as high as 1%.

For a plain old polyester film cap, this is something like ±0.0001%/Volt, IIRC.

If you have an audio signal swinging over a -12 to +12 V range being coupled through a thing like this, there will be measurable distortion arising from ~ 0.1%/V variations in capacitance.

Not that you would want to necessarily do that in the first place, since this thing has an 11V breakdown voltage, nothing to write Mom home about.

There is no one-cap-fits-all; right cap type for the right job.


All silicon capacitors are relatively expensive, they're specialty parts that generally go into expensive things (mmWave airport scanners, optical backhaul, etc).


Did they build 5,000 airport scanners at once? MOQ is brutal!


One scanner has way more than one channel…


Consider the device that they gonna be placed in, it's basically nothing.


A single 6MHz channel at the top end of UHF band would be enough to implement a universal cellular telephony service - simple calls and texts - at very low cost if phones had modems for it. I think that would be the better use of spectrum.


RF Channels 38-83 have all been taken from (US) TV since the 80s. Mostly used for mobile phones.

rf 70+ is 800 Mhz

rf 52+ is 700 Mhz

rf 38+ is 600 Mhz

Lots of phones support these frequencies.

Kind of annoying for tv, because cell towers on frequencies that used to be tv frequencies can overload amplifiers, so peeps need to go put filters up before the preamp.


It's not a great UI, but for messing with ideas in a VM, the free tier is very hard to beat, otherwise I'd be on Claude Code, but still on a VM, because I won't let them near anything I actually care about.
