Village:Seidenstrasse

Website
Description	A pneumatic tube system built from non-perforated (airtight) drainage pipe and vacuum cleaners. Being an Open Artwork, Seidenstrasse is a revision of the OCTO installation by the artist group Telekommunisten (http://telekommunisten.net/octo/, 2013). Features include decentralized mesh-style, push-preferred network with endpoints (no vacuum cleaners) and nodes (push-forward / pull on request). Seidenstrasse has been at 30C3 and 31c3 This Years new Features: TBD

Needs network	2) normal wired	Villages describe network needs
Needs power	2) Village with up to 30 citizens (16A CEE 400V)
Power comment	we will need to power some Vacuum Cleaners, and some ramdom equipment souch as drills and soldering irons, we will also have some computers
Village plans	... bring some special machines, ... have any other unusual installations
Village constraints	We do not make party but will make some noise., We would like to have trees on our village area, We like to show the stuff we do
Village comments plans	Buils the Seidenstrasse Tube network
Likes to rent a tent	No
Descibing tents to rent

Provides transport for
Has plans with tracks	We might try to intigrate the tracks in to the tube network as an alternative method of routing the capsules
Size needed	64 120
Has order interest	Yes
Planning notes	We would like to be as close to the Central "Aussichtsturm" as possible, as we will need to mount the tube to it and possibly rout it to our village, it also makes it more clear where to go if you want to learn something about the Seidenstrasse We are planing to use the vacuum cleaners again to power the Seidenstrasse, that why we stated that we are making noise, but we are not planing on playing loud musik.

How to make your own capsule

ALL Capsules need to be certified BEFORE use in the system, for certification call 4451 or 4452 or TBD

Everyone who wants to participate should build their own capsules. Please post your pictures, drawings, instructions and experiences here as inspiration for others.

Important: Capsules without light will not be allowed in the system! Attach at least one LED to each capsule, so stuck capsules are visible. No exceptions!

Tube dimensions (verified by measurement): Outside diameter: 100 mm Inside diameter (the tube is corrugated): 90-92mm

Capsule properties (verified by experiment):

	min	max	optimal?	comment
Diameter	75mm	90mm	85mm	also depends on capsule's sides, if soft, thicker may be better
Length	100mm	220mm	180mm	too short might cause it to turn and get stuck, too long will not get around corners. (rounded and narrowed ends can be longer)
Weight	-10t	550g	250g	large weights need to be tested more on long tubes going up

The ends of the capsule should be round or narrowed, so it can easily glide around bends. Take a look at how commercial capsules look like for inspiration: http://commons.wikimedia.org/wiki/File:Rohrpostbuechse.jpg

Do NOT buy commercial capsules. They won't fit!

A capsule made by cutting a ring out of a 85mm 1.5l PET water bottle and putting the ends back together worked really well in experiments (see picture below).

At the largest diameter a ring of felt or the soft side of velcro should be applied to ease the gliding through the pipes and provide a better airtight seal between tube wall and capsule.

Capsule Ideas: Multicolor glowing capsules, capsules with e-paper displays, encrypted capsules (with puzzles or locks).
