Hello,Troubleshooting · FormerLurker/Octolapse Wiki · GitHub )V0.4 Configuring a Raspberry Pi Camera · FormerLurker/Octolapse Wiki · GitHub
The camera test works but when I click on Activate Custom Image Preferences
I use a PI V2 camera
I finally succeeded but got stuck in the initial problem ... light flickering
If anyone can help me fix this I would love to
flickering in the timelapse or in the liveview stream?
It's probably all the automatic correction stuff like white balance or brightness control.
You can disable those automatic settings and set static values with this plugin.
You need to slightly change something in the octopi.txt for the plugin to work.
Here's a guide
# Plugin Setup
Most configurations should not require any additional setups, but there may be a few exceptions.
## Raspberry Pi Cameras ('RaspiCam')
The Raspberry Pi cameras, those that connect directly to the Raspberry Pi by a ribbon cable, need to be used in 'USB' mode.
An OctoPi installation can be configured to do this with the following changes.
First ssh into the pi (user `pi`, password `raspberry`), then:
Tell mjpg-streamer to use usb mode:
1. run `sudo nano /boot/octopi.txt`
2. change `camera="raspi"` to `camera="usb"`
- this tells mjpg-streamer to the usb mode
- if `camera=` has '#' before it, remove it
3. change `camera_usb_options="-r 640x480 -f"` to the appropriate resolution and fps, ie. `camera_usb_options="-r 1920x1080 -f 30"`
4. change `camera_http_options="-n"` to `camera_http_options=""`
- this enables the web controls in mjpg-streamer. while this shouldn't be necessary, a user reported it helped and it certainly shouldn't hurt

I'm already done these things to run the Custom Image Preferences
I will now try to change the settings

Did I miss something?
Could you upload a timelapse?
You may want to try the 'Powerline frequency' setting. Otherwise there may not be much you can do if it's the actual lighting from this side. If the lighting itself is varying, you'll need to try to stabilize it if possible.
To what value would you recommend changing the setting?
If I replace a lamp can it help?
The value depends on the frequency that is used in your location.

Malaysia step down their voltages to 230V.

If you use a DC powered LED lighting with a good PSU that would help the best.
I use an LED lamp
No, it still has the same problem ...
Mains powered LEDs usually are not that well filtered on the DC side and still can cause flickering.
Can I buy 220V lamps that will come filtered?
Usually not. They would be quite expensive due to the addition electronic parts
But how do you know they have a filter?
Usually not. AFAIK, they are not produced.
An incandescent light bulb would help quite a portion.
An alternative would be a small PSU with 12V 1A and with that 12V LEDs.
I'll try to buy some bulbs tomorrow.
