scientific, photographic, and person-lifting kites, 1900-1940

Baden F.S. Baden-Powell’s Manlifting Levitor. 1895.  No photos or film I can find.  Was it flat or bowed?

Charles Lamson’s Aerocurve, 1901


Samuel Franklin Cody’s Bat 1901 The best film is actually for a french aerial photography unit in 1917. The Cody kite is still used occasionally for high-wind aerial photography. Turn off the music.

Rudolph Grund’s Self Steering” Meteorological Kites, 1905-1940. They apparently adjusted their bridles to wind speed. There is certainly some rigging trick to learn from this series.

Topographic maps from fled kites

I just started building fled kites, but my fellow Grassroots Mapper Nathan Craig is already doing 3D topographic scans with them. He’s using AgiSoft’s PhotoScan, which is unfortunately not open source, and costs $179.  But as he points out, you just feed it images and it makes a damned good 3D model.

Mapping Colonialism, Talk on 4/9

This saturday I’ll be dipping in briefly to the Counter-Counter Insurgency Convergence, at Reed College.  Given my current work with community mapping, I’m very interested to see what Geoffrey Boyce has to say in this seminar:

In 2005 a group of geographers from the University of Kansas began a “collaborative mapping” project with indigenous peoples in the Sierra Juarez of Oaxaca, Mexico. Dubbed “Mexica Indigena”, this project was pitched to the participating communities as a means of empowering them to defend traditional land claims and practices through the generation of geo-spatial data. Yet, unbeknownst at the time to these communities, Mexica Indigena was in fact a program sponsored by the Foreign Military Studies Office at Ft. Leavenworth, Kansas – the pilot for a research program overseen by the American Geographical Society meant to augment U.S. intelligence and counter-insurgency efforts, now operating in the Dominican Republic, Haiti, the Lesser Antilles and Colombia. This paper explores the implications of Mexica Indigena for a number of issues of contemporary concern, including military / academic collaboration, politics, ethics, and the colonial legacy of disciplines such as geography and anthropology. Specifically, the controversial aftermath of Mexica Indigena exposes the deficiency of institutional protections against predatory research practices when the latter operate under the umbrella of U.S. “national security” interests – challenging common assumptions within the academy concerning the nature and beneficence of geo-spatial or ethnographic research, the position of Institutional Review Boards, and the value of academic research in general, in light of the colonial present.

Reed Arts Week

The talk and workshop went great. I was too busy to photograph the flights, but will get photos soon.  Su Liu came up with a great double-layer heat seaming strategy for her tetrahedron balloon- it was fast and quick:

Help Protei! Autonomous, oil-sopping sailbots

This is a project I whole heartedly support. Cesar Harada has put together an incredible team, and with a little money it is going to happen.

“We are developing Protei : a low-cost open-source oil collecting robot that autonomously sails upwind, intercepting oil sheens going downwind. Protei combines conventional technologies in an innovative design that we can implement in the short term to address timely environmental crisis.”
