Make sticks, crosswires, banner clamps and sheets for DemoCamp-units August 6, 2015 - 4:31pm

Find here a series photo's and instruction to assemble the first unit of a DemoUnit suitable for demonstrating but also for Occupy-like Demonstrative Camping. As you will see, the lens of the camera was dusty and the light was not very optimal. One day we will make better pictures, clarifying better.

Manual for assembling DemoUnits 1/2-size, made in 1982 August 7, 2015 - 12:06am

This manual is made by tracing photographs. At that time, 1981, these photographs were taken against a white background illuminated with spots. The slides then taken, were projected on the glass tabletop of a specially for this purpose designed drawing table, then traced. Some of Demotech's workers handled this tracing very well, producing such pictures in about 15 minutes.

DemoUnits in Tihange, Belgium August 4, 2015 - 2:37pm

First there was a demonstration in Maastricht mobilizing awareness for the leaking nuclear reactor just over the border with Belgium in Tihange. Spillage of radioactive waste in ground water would certainly affect the area of Maastricht. The girls from Cultural Center Mandril borrowed two towers from Demotech and organized support to carry these around Maastricht. People from Tihange became enthusiastic and wanted also to use the DemoUnit towers in a demonstration in Tihange itself.

VP PPump July 19, 2015 - 1:15pm

Paddy pump version December 2009. The pump here is shown pumping with an 85cm lift. Achieved 2L/s without to much effort. The biggest problem was stability on this uneven clay bank. As you can see at the end of the video, the top pipe needs to be extended and cut at a bigger angle.
