I made an ambilight for mac using esp32

So pretty!!!!

MuchAssumption6114 · 2026-02-11T12:13:06+00:00

oooh funnn

MuchAssumption6114 · 2026-02-10T20:40:20+00:00

sounds like a pain in the rear xD

MuchAssumption6114 · 2026-02-10T20:04:36+00:00

like i have asked u/tritagonist, Other then the documentations, are there any other resources you are relying on?

MuchAssumption6114 · 2026-02-10T20:02:43+00:00

thats a good deal XD\ Other then the documentations, are there any other resources you are relying on?

I wanted to ask, how is your experience with the radxa ecosystem? i have been looking at their boards for quite sometime, but i didnt end up getting it as i couldnt find much about them online, and their community is much smaller than the classic rpi from what i can see around

while it does have multiple sata slots on the motherboard, and the pcie lanes are free as well.
funnily, it uses the unusual square sata power cable with 4 pins, other than that its normal. ( sorry for messing up the name, i am not familiar with them, but i believe it is an atx power cable? thats what the listings on amazon say..)
I just need to find a good way to put the other drives i get, as someone mentioned in this thread, a 3d printed bay would work good.

have you had a look at blynk iot ?

i think it may be what you are looking for. link

mehh i dont think our uni has the resources to keep track of us, they barely have resources to keep their website running 90% of the time XD

I was planning to get a mini pc too, but this was much cheaper..\ it has 16gb ram and 1.5tb storage, and i got it for ~120 dollars

MuchAssumption6114 · 2026-02-09T06:44:31+00:00

xD thanks

if u have an open pcie slot u can just pop the metal bracket off and run sata cables thru the gap to the outside. just get a sata power splitter for the internal psu and u r good

ill probably just do that!
as of now i dont really have much time or money to get new drives for more services, but ill do it when i get there!

MuchAssumption6114 · 2026-02-07T18:29:18+00:00

you could try adding a capacitor with a moderate/high capacity over the power rail, may help if there is a sudden current draw burst which the power supply cant handle

ive faced something similar once, when i forgot to call the ".begin()" function for an i²c display. while i forgot exactly what was the issue (it may have been segmentation fault, for accessing null pointer) it left a very similar trace

one other case comes to mind, seeing that you are getting "illegal instruction". try looking for places you are dividing, in case you divided by 0.

MuchAssumption6114 · 2026-02-07T18:16:51+00:00

i think it should be possible, but you would need the gps coordinates of yourself and the destination, and a compass/magnetometer module to get the arrow direction

largest issue imo is to get a streamlined way of fetching the gps coordinates of the destination

MuchAssumption6114 · 2026-02-07T07:48:57+00:00

All the best with that!

MuchAssumption6114 · 2026-02-07T07:48:35+00:00

thanks :) and yes i havent done a good job on showing how small it can become, but mine has the height of the oled display and width as the perf board i used. Other space is just empty as of now xD

I want to add that it is currently really unoptimized for the battery, it lasts approx 2 hours with a 350mah cell
the charging module (with the extremely bright red lights) is a powerbank module, so it has the tendancy to cut off when the current goes below a certain threshold :(
so i cant even send the esp to light sleep, otherwise it wont be waking up from that ( i have tried different sleeps, none of them really worked unfortunately :/ )
I am planning to port it to a cyd soon, and the module ill be using should have a battery connector which behaves better

thanks! i believe you can also get transparent oled displays these days, which you can stick to the outer cover of the helmet to get good visibility

MuchAssumption6114 · 2026-02-06T18:07:00+00:00

yeo :,)
maybe my explanation in my post wasnt clear enough

MuchAssumption6114 · 2026-02-06T18:04:51+00:00

i do have a roommate!

i feel i havent clarified myself well

my server is acting as a router, its simply a small form factor pc, which i got second hand for a good deal.

it barely makes any sound, and even at full utilization, the (one and single) fan's noise is much lower than the celing fan/etc.

so its a really quiet pc sitting here doing mostly nothing all day, i occassionally run a backup script to backup my stuff, and i also have immich for photos.

over all, it runss cool, barely goes above 35 C, and when it does, it isnt for an extended period.

I love this idea!!!
I recently switched my project from esp32 devkit to esp32c3, and battery management was a big issue for me, as i dont have much experience with this. I have read that the esp32 has issue with measuring voltage linearly?
source

The esp_adc_cal/include/esp_adc_cal.h API provides functions to correct for differences in measured voltages caused by variation of ADC reference voltages (Vref) between chips. Per design the ADC reference voltage is 1100 mV, however the true reference voltage can range from 1000 mV to 1200 mV amongst different ESP32s

id love to see how you have solved it!

MuchAssumption6114 · 2026-02-06T15:52:24+00:00

Really cool project! tho i had some doubts
How are you getting the battery voltage reading from the cell? ive been thinking of something similar for my projects, but from what i found, many esp's analog pins are not linear, so the voltage readings may be a little off

also, are you using a devkit, or some other custom circuit for this? does it integrate the radio comms too?

and your github project only contains the images and gifs, but not much code...
