Amazing!

At IMVEC we're working in a couple of cameras using RPi zero and one of them involves internet connection to display obtained images online.

Both involve the use of the Witty pi mini board to manage energy of the pi.

Using the combined image everything goes like a charm. The camera is accesible and the command line works perfectly.

Trying to connect to internet using wifi I'm unable to turn off the acces point and turn on the wifi.

I've set up wifi credentials using wpa_supplicat (wpa_phrase and so on..) and turn ap0 down using "ifconfig ap0 down". After this "ifconfig wlan0 up" but nothing happens... How can I do this?

Woul be great to have a little interface in the captive portal page to turn of acces point and connect to a wifi signal and download packages needed for the different recipes ;D.

I understand further connection should be done using terminal + keyboard + monitor...

This is great to hear, @xose - I've actually found that it should be possible to get a Pi Zero W running BOTH as an access point and connecting to another WiFi network. 

I've started an issue here to work towards a recipe for that: https://github.com/publiclab/pi-builder/issues/34

We do have a web terminal connected too, which can help sometimes, in one of the recipes at https://github.com/publiclab/pi-builder/pulls

Would you be interested in posting some of your configuration steps to the above issue (or another that interests you) and we can work towards getting a reproducible build of that setup for anyone to download? The hope is that small incremental improvements to the image can be retained and versioned, making them more reproducible each time a change is made. This can be hard with Pi development -- so much can be lost since it's all "trapped" on that SD card :-)

Have you had much luck with the timelapse feature of RPi Cam web interface? I had some trouble downloading it in bulk since it tries to generate a .zip file, which then fails in the web interface.

Also, interestingly, we have Infragram running in live-streaming mode pulling from the Pi camera on a web interface hosted from the Pi!

Hi, I am trying to download high resolution PI camera V1.3 images but Pi Builder locks up or produces files with no data. Is there a setting for high resolution picture settings ? My settings are attached. Not interested in video just trying to get 2592 x 1944 pictures for microscope observations. Thank You

Oh also I was looking for references and found here that you could also try gpu_mem=256.

@icarito Thx for the information!

-Really like the interface, just fine tuning its application. -After a little experimentation, the interface can capture/load large format images if the Quality setting is adjusted to 100. its buried in the RPi-Cam-Web-Interface link you provided above:

"There are 2 settings to control quality and compression. Quality (1-100) controls the quality of the live image preview, and image_quality (1-100) controls quality of still image captures. The number does not match normal jpeg Q factor as the Raspberry camera compression software Q factor is quite non linear. The default 10 is approximately equivalent to 75 in normal JPEG usage and gives a decent trade-off between quality and file size. 7 is about Q 50, and 20 is about Q 95."

-I have been able to download large formats from v1.3 and 2.1 with no problems (with the Quality setting=100). I plan to post some pictures soon.

-The only problem I have now is that the my pi-zero locks up after about 20 minutes. Its behavior becomes erratic - the WiFI may not connect, may not store images or can't access commands). Have you ever had any problems with overheating? Since the camera mount prevents adding the supplied heat sink, not sure how to fix?

Thx again for your detailed response.

I just flashed the latest image onto a Pi Zero W and the browser livestream works as advertised. That's super cool and exciting. I'll be sending it up as a lightweight option for KAP - if I get any cool results, I'll be sure to share. Thanks for doing so much heavy-lifting!
