_DSC7046 - Raspberry Pi Zero + self powered USB hub

60x90cm stripbox hung camera left and up with white bounce/fill card opposite
This is 2 exposes blended for the LEDs - the 1/30th sec expose registered the LED but not as bright as I wanted - the flash also wiped out the intensity of the LEDs. Second ambient only exposure (including the ghost/flare on the green LED) blended using "overlay" mode.

This is a Raspberry Pi Zero sitting on top of 4x port USB hub made by a Czech company called UUGear. The RPi Zero has 1x mini USB port for devices but it does not supply enough power for anything requiring above 100mA it seems.
My cheap wifi dongle (the RPi Zero has no ethernet of wifi!) wanted more current which the RPi provided and as such was hugely unreliable to bring online. The UUGear USB hub is a neat solution that requires no soldering or extra wires and powers itself from the 5V rail of the RPi (via test pads on the underside of the PCB). With the hub attached power is no longer a problem (each port can draw 500mA or single port can draw up to 2A according to the documentation) so the RPi Zero can now use my wifi dongle and also attach keyboards and a 2.5" USB hdd too!
Downside? The RPi Zero's small form factor is appealing for some uses but its got less of everything else too: USB ports (1 vs 4), connectivity (none vs eth/wifi) and processing (1x core 1Ghz/512MB vs 4x core 1.2Ghz/1GB).
Getting network connectivity like this brings the price to ~23GBP (RPi Zero 4GBP plus 2.50 delivery, Zero4U 10GBP, wifi dongle 6GBP) which is 69% of the cost of an RPi3.
