interval with microcontroller

In the past year i've been trying to get chdkptp to work with my cams the way I wanted :)
the best results were with multicam from reyalp.
however since there is this slight problem of memory with large numbers of pictures when using the usb-pc connection i was forced to reboot the cam twice a day.
i tested this for a while and although i only had 2 reboots where focus was off, still felt this was not what i wanted.
tried to approach it differently in the hopes of tackling the file/memory limit while still being able to pull the pictures from the cam, but i'm not that good ;)

and because i wasn't able to solve that and philmoz already fixed almost all my cams up with support for very large sd cards my choice was to look into the usb remote
https://chdk.fandom.com/wiki/USB_Remote

this is mostly because i wanted a more accurate time than the cams could provide over months and my way of handling that....Not :lol
so by now i build something on a pico w that tries to use wifi to sync time once a day.
it can run headless with only a led to indicate the focus-shoot time, but it can also work with a small touchscreen giving more feedback and the possibility to set it without another computer to upload a new config file....could have made a webpage so you could set it on your phone, but that is not my thing.
for now i'm testing it, just entered it's third week and hasn't missed a beat.

i'm still refining the code for the cam and the pico. and must design a casing...either lasercut or 3d print. but i have no good idea for that yet...it's more complicated than i first thought.
so i have nothing to share yet, but an image   :xmas

if anybody has ideas what would be nice to have on an external intervalometer, i'm open for suggestions now i've got it doing what i want.

f.i. i have an m3 that uses IR for remote, do we have the codes that are used, so i could replicate that with the pico? and put some ir led on it to test if i can get it going?
or are there only a few models that support ir and is the bulk going over bluetooth now?


btw. it also includes english days and month for those who are wondering what that means.

The big advantage of the M3 is that I no longer need an external device  ;)

fi have an m3 that uses IR for remote, do we have the codes that are used, so i could replicate that with the pico?

I once downloaded code for an Arduino. But first I have to look for it.

or are there only a few models that support ir and is the bulk going over bluetooth now?

Unfortunately, the M100 no longer supports IR.

Unfortunately, the M100 no longer supports IR.
and also has no connector for a wired one.
really unfortunate, as far as i could understand it needs wifi & bt & location to work, i have a room thermostat that has the same unnessesary complicated needs to connect.
usb only i'd say for the m100, either with chdkptp or remote.

I found the code. I'm not sure if I can share it here. If necessary, send me a PM with an email address.

c_jourg, i have send you a pm with email adress, i already found a few ir leds, so when i've got time i will give it a go.

while i'm now testing this new setup i really miss the instantly downloaded images i had with chdkptp. alas i didn't want 2 reboots a day, otherwise i would have known by now.

did it catch the Geminiden meteors this evening?
i'm really eager to check the results, but i must be a good puppy and wait in my basket until it's time to exchange sd cards, next year if all goes as planned ;)
