Oktopussy Failsave Test

The most interesting thing about 8 Engines is that some ( up to 4 ) can fail without causing a crash. We made a little video while we tested this "Feature":

DUBwise RC-Mount

Since i build the DUBwise Range extender - there are some new usecases in which i use dubwise while the MultiKopter is in the air. For that i needed a mount that i have my hands free for flying. This is the mount i build from parts i found in my Hobby-Room ( price of parts <5$ ):





weight of 87g with sun-protection - which is very ok for mounting on the RC:

DUBwise Range Extender

Finally i had some time for a Project which was in my mind a long time - the DUBwise Range extender.


The Bluetooth Modules in Mobile Phones are very limited in Range ( for reasons of power consumption and size) - which is OK for normal usage of Mobile Phones but was a problem for some use-cases of DUBwise.
The range extender is a little box for the jacket which contains one Zigbee-Pro module ; a Bluetooth Module and power supply. Zigbee and BT are crossed ( rx=>tx ; tx=>rx ).



Now I connect to the BT module in my jacket with the Mobile Phone ( which is <10m in range normaly ) and the (long) distance to the MikroKopter is Made by a ZigBee Pro connection. ( specifyed range ideally by 1mile / 1.6 km )

Beside the range there is one more advantage. I can leave ZigBee on the MK permanently - I dont have to switch between Bluetooth for DUBwise usage and ZigBee for Riddim ...
