Well,
flash - lightning
crack, router plus a ton of other stuff arguing about whose voltage is bigger
rumble - thunder in the distance
bugger that sounds expensive - me.
We had a thunderstorm on Sunday night, 12/8/18. We get a good number of thunderstorms and today's was average. Lots of rumbling and flashing, but not close to us. Tonight we'd had 2 blackouts of ~2s, then there was a flash outside and load crack from the main distribution where the VDSL router and IT stuff lives. The thunder suggested the lightning was not near by!
18/8
re-fitted the phone line protection; this was installed with the ADSL router in 2010, but reduced the speed too much, so got removed again. We got upgraded to VDSL, and I never tried the filter. Today, I have just tested the speed with and without. We get a 97/12.3M connection to the local box, which was reduced to 90/12.0 Using speedtest.net, the speed went from 12/42 to 11/40. This change is probably within the bounds of variation during the test; we're usually throttled back to 12/30, so it looks pretty good today. The filter can stay until they give me back the bandwidth to 97M !
I do need to separate the phone line wiring from the CAT5, and put an earth connection directly from the earth rod to the phone socket, rather than going via the dis board (normal install) - done.
The death toll in active components is quite impressive, as is some of the damage (splash marks)
Cabled weather station (PIC16f884 working, but comm port dead)
Main processor (CPI) (PIC32MX775F512H and power monitor ADE7953. PHY + EEPROM ok)
Main processor IO (opamp for water meter, 1W i2c conveter ds2482-800, 1W mux ds2408 74HCT244, BMP180)
Caller ID (ESp8266 + dsPIC33FJ128GP, opamp. EEPROM 25l256)
12V to 3.3V/5V regulator AC, 5 + 12V fuses, plus regulator chip+fets
12V battery backup. 2 Fets that switch 12V. The other 2 that operate battery undervolt were energised at the time and ok. Both 1W devices
5V relay for garage door power - tracks fried from live to +5, plus protection diode to 0V. Works ok after clean. Relay believed off at the time.
Garage 1W dual IO DS2413.
mains SMPS for all devices - both main diodes, both output caps swollen, a zener crowbar
LF356 on burst controller. pic ok.
All 1W temperature devices (2 wire) all survived
Rpi connected via ethernet cable, but unearthed psu ok
New burst controller / power monitor running direct off mains ok.
