Welcome on the DIY Wireless Bug(s) community website. 
DIY Wireless bugs are small and cheap embedded devices used to build a simple wireless network. 
This website provides informations to build this kind of network. 
 
We decided to produce our own wireless protocol and board due to various facts :
-  Zigbee isn't an open protocol (requires licence)  
-  No really opensource Zigbee stacks exist (we're not able to distribute them ..) 
-  Most zigbee stacks are not hobbist friendly (requires special compilation tools, lot of code..) 
-  Zigbee requires lot of flash/ram (96Ko used by bitcloud for example) 
-  Zigbee boards aren't cheap 23$ for the basic XBee  
-  Zigbee boards aren't hobbits friendly (requires some custom boards, connectors ..)
