Show HN: File-server activity gauge with LEDs & Raspberry Pi

Linux on the RPi probably supports blinken lights, too, through the LEDs interface. One of the triggers for a LED is a "heartbeat", which reflects the average load of the system; the higher the load, the faster the light blinketh.

Are you suggesting a Kernel module for the Blinkt??

No, I'm saying that similar functionality has already been implemented. Try `echo "heartbeat" > /sys/class/leds/led0/trigger`

Heh cheers, I just found /sys/class/leds/dell::kbd_backlight/brightness :)

I'm not sure how that would work with the larger Blinkt RGB display?

Rpi's are "cloud" storage now?

So the Raspberry Pi is not running Minio (it can, but it isn't) - Minio running wherever - in the cloud if you like is emitting webhooks and the Pi is feeding off that to know what color to go.
