Re: Setting up Dynamic DNS to view Pi camera stream

If your Pi is behind a router/firewall you need to set up port forwarding. Your router doesn't let anything in unless there is port specific forwarding set up. Find your router's port forwarding setting and set it up to route TCP requests for port 8080 to port 8080 on your Pi's internal IP address.

Re: Motion - MMAL camera

So far I have been a happy motion-mmaluser, recently I added a PIR sensor and would like to take a snapshot with raspistill whenever actual motion is detected. Has there been a way found to have motion-mmal and raspistill coexist?

Richard, thanks for the reply. I was looking for a way to keep my setup running without the need of physical intervention. I guess I have to look into other options.

Switching individual USB port on/off

Every once in a while my USB powered LCD keychain display gets stuck with a 'whitescreen'; powercycling restores it to operational mode. Under raspbian, am I able to control the power for the on-board USB ports individually?

Thank you for your feedback. I know it is feasible and it has been done (e.g. with arduinos), just apparently not with a Raspberry Pi.

Re: Infrared receiver, destruction possible due to pinout er

Update: I followed the pinout from the spec sheet of a similar looking module and it works. I am amazed that something can be hooked up directly without the need for resistors or anything else. I wonder if I can connect a photodiode in a similar fashion. I'll hunt around.

Re: Infrared receiver, destruction possible due to pinout er

If that's the only risk, the IR module going up in flames, then I can live with that.

The pin out seems fairly standard. Pin 1 data, pin 2 ground, pin 3 +ve. I can't see you damaging the Pi or the receiver. I've connected a similar receiver back to front a few times and it is still working (did get very hot once). Thanks for the quick reply. Pin 1 seems to be data in all cases but w...
