Re: Alternatives or replacements for camera flex cable?

Whoops, I was describing the wrong connector! I thought you were talking about the cable between de camera PCB and RPi.
The cable between the sensor and it's PCB has a much, MUCH finer pitch, and maybe more coonections, I don't remember.

Re: Alternatives or replacements for camera flex cable?

They should both work, you just have to keep in mind which version you have when hooking up your other electronics and FPC cable (same-side or opposite-side).

It's a 1mm pitch 15way FPC/FFC connector. That's probably all you need to know :)

If you want to use UTP, I'd suggest using two cables so you don't have to abuse the shielding. We might even try it monday, it sounds like a fun experiment.

Re: Alternatives or replacements for camera flex cable?

Yep, that should work. We think two opposite-side cables would be preferable, because everybody with a RPi camera already has one opposite-side cable. If you accidentally use the wrong cable, you might/can/will (I don't know, and don't really feel like testing this) blow up your camera and/or RPi.

Re: Alternatives or replacements for camera flex cable?

I fixed the URL.
For our extender, you will need a same-side and opposite-side flex cable. A next version will probably need two opposite-side cables.
I'll check if we can get shorter cables, but I'm afraid it will be difficult. I will post updates in this topic.

Re: Screen Advice

The LCD in the image above has a piggyback board from bitwizard (www.bitwizard.nl/catalog), that allows you to control it over I2C. There's also an SPI version available. You could, however, just run your display from GPIO pins, it only takes a little more wires and time/effort to get it working.

All right, just continued with the display. I removed a 2R2 resistor, which was in use as a fuse, from the PCB, to disconnect the on-board 5V regulator, and soldered a wire to the correct pad of the fuse. I am now powering the display from the GPIO header of my Pi, and it is working! One drawback: I...

How much CPU is "waiting" according to top? It could be that you have a slow SD card, and that the CPU is wailing for data from SD.
