Hi Guys, I'm on my way of building a Night Vision camera using the Raspberry Pi NoIr camera and 10 of these LEDs . The camera is recording a constant loop and objects that are +- 2-3m in front of the camera. I have the following two problems: 1. The Noise of the image is quite high, which actually m...

RasPi WiFi Hotspot sehr instabil

Hallo zusammen, ich habe auf meinem Raspberry Pi "erfolgreich" einen WiFi Hotspot eingerichtet (nach dieser Anleitung ). Wenn die Verbindung mal stabil ist, funktioniert auch alles. Leider ist sie nur sehr selten stabil, wie ein Ping auf den AP WiFi Dongle zeigt: Antwort von 192.168.1.1: Bytes=32 Ze...

Re: RasPi WiFi Repeater

The IPs are static as the NIC didn't get any connection, so I wanted to exclude the possibility of dhcp problems.

Re: Function Variables usw in While

You guys are right. I've had a second print altitude line somewhere else in the code for debugging which caused the error.
The TimeFIX was a typo and has been corrected as well.

Thank you guys for helping me out!

Re: BMP085 on Raspberry Pi with Python

Good guess.
Do you think it makes sense if I measure the average difference to my other sensors and add this value as offset?
Would that offset need to be fix or a percentage? (I'm asking this as I don't know if the offset might get bigger with higher temperatures hence lower with lower temperatures).

Hi Andy, thank you for your code. Running your code and the one that I've got are getting pretty much the same values. But still... checking the Temperature at 5 different sensors, the BMP085 is quite off: BMP085 (using my code): 23,90°C (Pressure with my code): 989,42 hPa BMP085 (using your code): ...
