Re: Recommended IR filters for Pi-NoIR

In case others are curious, the Roscolux #2007 Storaro Blue (aka little blue square that comes with the camera), it actually filters blue. This helps botanists and hobbysts monitor the health of plants. More here: https://www.raspberrypi.org/blog/whats- ... oing-here/

Re: Raspberry Pi B+ turn usb power off

At least on the raspberry pi 3 b+ (likely all 3s) the hub is 1, not 0.

The following should turn the power off:

Code: Select all

sudo ./hub-ctrl -h 1 -P 2 -p 0
I suggest you try:

lsusb

and use `bus` and `device` as like suggested on the README:

Code: Select all

sudo ./hub-ctrl -b 001 -d 005 -P1 -p 0
