I found an amazon basics color changing smart light bulb attached to a lamp my neighbor threw in the apartment dumpster.

@MLE_online then there will still be someone who tips first and finishes before I do.
I would like to see the blob side of the pcb tho.@RueNahcMohr here you go. I got most of the blob off

Hey yeah! Esp32 pico!
@MLE_online
Aside from everything else, it is simply utterly ridiculous to have a computer in a fucking lightbulb. -

Apparently you can only change the color by giving the bulb access to your wifi network and using the alexa app on your phone. Very stupid.
@MLE_online #Amazon is notorious for crippling products to force their walled garden.

I have no idea which pins of the esp32 those lines going to the LED driver are associated with, btw. They put a giant blob of very stiff silicone over all of that
It looks like it's specifically one of these

@MLE_online @RueNahcMohr That looks like a wireless card attached to a power supply. The blob may have the logic underneath. It might be a gate array, if they don't need to ever change the IP they talk to. Some companies hate paying programmers, and who needs a CPU, anyway? I haven't noticed anything to store the IP data yet, but I'm more software/firmware than hardware. It probably isn't socketed, because that would cost money in the form of pennies. Product numbers off of the stuff under the blob would be helpful.

@MLE_online @botvolution The EnshittiBulb
on that same note I'm planning on writing my state representatives about AB 2047 because that just sounds like an absolute License to Enshittify for the few 3d printer manufacturers who would jump through all those hoops and probably do it by tying their devices, including ones bought with public funding for schools, to a cloud service that can just Go Away and brick the printers, or force you to buy the manufacturer's own RFID tagged filament

Ok, it's controlling a BP1838 3 channel dimmable LED driver chip: https://datasheet4u.com/datasheets/BPS/BP1638CJ/1495890
If someone out there is smart and wants to try throwing some code together to see if it will work outside of the amazon ecosystem, let me know and I'll try loading it onto the ESP32
@MLE_online dump its firmware.

@steter @RueNahcMohr It's an ESP32 pico v3 zero attached to a power supply

@MLE_online dump its firmware.
@maehw I don't know how to do that

@vxo @botvolution You should explain what AB 2047 is for people who don't know what that is.
The lawmaker proposing that bill is also proposing to require drivers licenses for ebike. She's on a roll with stupid ideas right now

Aside from everything else, it is simply utterly ridiculous to have a computer in a fucking lightbulb.@botvolution @MLE_online many not-so-smart lighbulbs have an 8-bit microcontroller on them. I saw an emulation of the Manchester SSEM running on one once

@MLE_online @RueNahcMohr Cool. Cheaper than making an assembly line. Neat use for it.

@MLE_online 32 pin...

@RueNahcMohr so it will be an exciting challenge for you!

@nickzoic I see test pads for 108 and 109 on the PCB, so something isn't adding up here

@nickzoic "O7/IO8/IO9/IO10/IO20 belong to VDD_SDIO power domain and cannot work when VDD_SDIO power shuts down"
this means something, but I don't know what
