Comaptibility

Tested and 100% compatible: Raspbian 8 Lite (jessie)

Now testing Raspbian 9.1 (stretch)

Forward traffic

For example, if eth0 is configured to use internet and wlan0 is access point (WiFi hotspot), you can do this:

forward.sh eth0 wlan0

Poof! You have access to the internet on your wlan0 now.

Temperature

Just shows current CPU & GPU temperature. Real-time monotor: watch -tn 1 ./temperature.py

Example output:

CPU: 50.5'C 122.9'F
GPU: 49.9'C 121.8'F

GPIO

Control GPIO pins with easy syntax: gpio.sh pin value

• set pin 18 to 1: ./gpio.sh 18 1
• set pin 15 to 0: gpio.sh 15 0
• gpio.sh 17 sets pin 17 to 1 or 0 depending on current value. It works like a switch.

Example:

$ ./gpio.sh 18 1 # pin 18 will be set to 1
$ ./gpio.sh 15 0 # pin 15 will be set to 0

$ ./gpio.sh 17 # pin 17 will be set to 1
$ ./gpio.sh 17 # pin 17 will be set to 0

CPU governor

Raspberry Pi supports several CPU governors. For example: powersave, ondemand, performance.

List available: governor.py -l

Available governors:
 - conservative
 - ondemand
 - userspace
 - powersave
 - performance
 - schedutil

Current governor: governor.py -c

Current governor: powersave

Set governor: sudo ./governor.py -s performance

Random MAC

Requires macchanger package.

Changes MAC on all interfaces by default. But you can specify one manuaally: randmac.sh wlan0

Net monitor

Requires ifstat and bc package.

Switches GPIO pins depending on current network bandwidth. Works like an indicator with LEDs connected to the GPIO.
