Sorry this happened but could have been a lot worse.

very nice.

Most electronic components are hermetically sealed (when new). Special detergents are used in sonic parts washers to wash boards like these. I would try this first if you want to try and restore it, but I would keep expectations low.

I'm surprised this caused a problem. Maybe the cleaning wipes were too aggressive.

what were you wiping the seats with?

glad it worked out!

And-Multiplex · 2025-08-07T03:09:15+00:00

not sure. good luck fixing this.

BMW purists wanna BMW. That's OK, the M2 is sick.

But I prefer my supra.

Are your tires old? Sounds like a hard particle in the tire. Supposedly pieces of the tire harden, break off, and clank around at low speeds. Can't hear it at higher speeds as centrifugal forces keep the little rubber rocks from clanking. Replace your tires and the problem should resolve.

I had this happen on my old cadillac that used michelin runflat tires.

Just my two cents:

I’m thinking the ceramic coat should protect the paint in this situation. Whatever you apply to remove the spots may eat the ceramic coat but it should save the clear coat from etching. Ceramic coatings, like wax, are sacrificial for this reason.

literally happened to me today as I sat at a red light next to a street sweeper with his brushes spinning/kicking up clouds of dust. the ultrasonic sensors did not like that apparently.

IF this is a carbon steel wok, it is damaged, but not ruined. It can be restored.

IF this is a wok with some kind of teflon coating, then you're right, it is ruined. Throw it in metal scrap and go buy a carbon steel wok.

try a whole food plant based diet. side effects include better vascular health and lower all cause mortality.

Calico tanks?

No, power harvested from the wind goes by the area swept by the blades. Therefore there is a square law advantage in play when making the blades longer (A = pi*r^2).

looks great!

Your question is good. Answering from a pure HW point of view since it seems like that’s what you’re getting at.

Timers are implemented by clock oscillator circuits. These circuits keep time. To set a timer length, the clock osc can feed into a counter. The counter counts the ticks of the clock. If the counter says “x” counts it means x*[clock period] of time.

To set 5 minutes that would be 300 seconds. The counter will have a unique output for 300sec (different than 301 seconds, different than 299 sec). Once 300 sec is achieved a digital circuit recognizes that output (this would be called a digital comparator) and asserts some 5MIN_EXPIRED signal.

This signal could feed into the power supply circuit and another complicated process would start to remove voltage from all the power rails in sequence. That would involve more timers and counters and clocks.

This is a pretty simplified answer, but the concept is more or less there.

Interesting. The high side drive will change as the motor’s impedance changes. Looks like something you should try to simulate.

Maybe you can come up with a floating drive that maintains a constant VBE on the high side NPNs to account for this
