UPDATE !! In V3 I added two 25mm x 7mm 5V fans because the OPI Zero does run a bit hot

V2 now contains a USB hub as well as a better accomodation for OPIs antennae. Additional Parts: Micro USB UB (https://www.amazon.de/gp/product/B000FS12IG), without its case of course

Being on the road quite often and killing time at hotels I needed a portable testlab to do some experiments in network secutity. Orange PI Zero was the tool of choice for its small size and versatility and the original thing was an ideal base as it was the slimmest case to be found.

Ths case accomodates: -Two OrangePI Zeroes -Tenda Unmanaged Switch without its casing (https://www.amazon.de/Tenda-S105-Unmanaged-Switch-RJ-45/dp/B0029M7TJC/ref=sr_1_1?ie=UTF8&qid=1499934516&sr=8-1&keywords=Tenda+S105+L2+UNMANAGED+SWITCH+%285x+RJ-45%2C+1Gbps%29) -USB to Serial Adaptor (http://www.ebay.de/itm/FTDI-Adapter-FT232RL-USB-zu-TTL-Serial-fur-3-3V-und-5V-fur-Arduino-PRO-Mini-/331744431360?hash=item4d3d824d00:g:AVYAAOSwyWZZUKis)

Some 2.2mm screws of variable lengths (6mm to 30mm) are needed for assembly.
