Here is the design and instructions of this smoker: http://learningbeekeeping.com/beekeeping-articles/bee-smoker-design-for-third-world-beekeeping/
Peace Corps volunteers and NGOs that do beekeeping should find it useful. Assembled from scrap, with no power tools. Only a hammer, nail, machete and maybe pliers.
After much trial and error, over the last year, I've come forth with a simplistic bee smoker design for use in third world areas. This began as a project with Paul Jackson when I interviewed him to make a documentary about his bee smoker collection . Drawing upon my experience in East Africa in the Wagogo tribal areas of Tanzania, I think all the materials needed could be found in most villages in the bush.
I'm calling it the 'Jackson-Taylor 3 can smoker'.
