The strength to weight of bamboo is high enough that it was used as ski poles before aluminum.
Three years ago, I saw bamboo used all over China in traditional housing, furniture, musical instruments, cooking utensils, all manor of light construction and, most incongruently, as scaffolding during the construction of high-rise steel-reinforced concrete high rises.
We were told that there are many species of bamboo and some are used for food, some for structural work, etc. If, as a westerner, you grab a piece of bamboo willy-nilly, it might be like someone new to wood working attempting to build furniture from eucalyptus, airplane wing ribs from ironwood, use pine for cooking, and balsa in a post-and-beam house.
Don't take that as a criticism, I certainly don't know any better myself. But whatever you're able to achieve in your first effort, could be optimized greatly with better materials.
