Re: [Tutorial] How to plug two camera modules on a Raspberry Pi

hello Villota44, It seems like there is an error in the Pi zero disk image. I had trouble following the exact steps in the guide preparing the image files. In particular using the truncate command did not work for me. Instead, I used Gparted in Ubuntu to resize the partition on the SD card before us...

Re: [Tutorial] How to plug two camera modules on a Raspberry Pi

I switched from streaming as in laurent’s tutorial to installing Pikrellcam on the Pi 3B and the two Pi zeros. With all three running in separate browser windows, the cpu loads seem remarkably low, less than 10% on the 3B and around 20% on the zeros. There is almost no lag between waving my hand in ...

Re: [Tutorial] How to plug two camera modules on a Raspberry Pi

Very unlikely to happen. People complain enough that the current connectors are fragile, whilst the Sunny type connectors are even more so, and very prone to popping off at inopportune moments. You've also then moved all the voltage regulators and oscilator for the camera module onto the Pi, and th...

Re: [Tutorial] How to plug two camera modules on a Raspberry Pi

Very nice tutorial. I've gone through the steps without major problems. (Several steps seemed to require the use of "sudo'.) I decided that I really wanted three cameras (at least), using each for a different field of view. So, I added a third camera on the master Pi 3B. This seems to run fine with ...

Anyway, my understanding is the foundation set the recommended retail price for the camera everywhere at US$25 (pre-tax/shipping) so anything above that is going somewhere else.
