Sanity check: ESP32-controlled P-MOS high-side switch

Sanity check: ESP32-controlled P-MOS high-side switch

Hi,

Could someone sanity-check this small high-side switch block?

I’m using an ESP32 GPIO (12V_EN, 3.3 V logic) to switch an OLED supply rail. The input rail is currently named +12V, and the switched output is 12V_OLED.

The net names still say 12 V, but the final rail may be higher, possibly up to around 15 V. Because of that, I added the resistor divider on the P-MOS gate instead of pulling it directly to ground, to keep Vgs within a safe range.

The intended behavior is:

  • 12V_EN low → OLED supply off
  • 12V_EN high → OLED supply on

Could you check whether this topology is correct, especially the P-MOS source/drain orientation and the gate divider?

Schematic attached.

Too much oil during first seasoning — keep cooking or strip and start over?

Hi everyone,

Complete newbie here. I’ve read quite a bit, but I’d like to ask for advice based on the photos.

I seasoned my first carbon steel pan - unfortunately before I found this subreddit :) - and I now realize I used way too much oil. After around five cooking sessions, it looks like this.

My question is: should I just keep cooking with it and hope everything evens out over time? The visual appearance doesn’t bother me at all. Or would it be better to strip it and start over properly?

Thanks in advance for any advice!
