New payload bus

2011-10-02T22:22:55Z

Marcus10110:

The new payload bus will be based on a multi-level tower design made from laser cut plastic disks and carbon rods used to support the structure.

Currently, the plan is to encase the frame in Styrofoam tortilla warmers, which will serve both as isolation at altitude as well as destructible landing padding.

TODO: add spacebridge logo to all images.

== Onno Ring ==

The payload design depends on plastic planar structures to act as mount points for all payload components, as well as load-bearing points for the balloon and parachute.

To facilitate this design, Onno has designed a revolutionary new geometric shape which has been estimated to be between 100x and over 9000x stronger, lighter, and cooler than an ordinary disk of the same material and approximate size.

Standard mounting plate for cameras:
Please note, this does not use the Onno ring, so it is the weakest part of the design, by approximately 900000%.

[[File:Spacebridge_mount_ring.PNG|500px]]

== Power Supply ==

In the past, most equipment on the payload has been individually powered by it's own battery. This strategy has been successful in removing power as a possible single point of failure, but it has cost weight in the design. If we can design a power system which would keep critical components running while shutting down less critical systems, then the whole system should be able to run off of a single battery.

The first problem with this plan is that most of the components run off of different, incompatible voltages. To solve this, switching voltage regulators should be used to maximize efficiency.

Current design:

[[File:spacebridge_power_sch_v1.PNG|500px]]

This design still requires cutoffs for non-critical systems, as well as battery monitoring. This system will not be ready for the next launch.

'''Space: the final frontier. These are the voyages of the hackerspace Noisebridge, our ongoing mission to explore strange (yet economically priced) new ascent technologies; to seek out new parts and new partnerships; to boldly go where no non-government-or-massively-industrially-funded-group has gone before.'''

== Project Summary ==
Spacebridge is a project that documents the necessary steps to produce a cheap and easy deployment platform for lofting instrumentation and photographic equipment into the stratosphere. We approach this project with a heavy slant towards education, with a hope to bring science education away from something that you know because of a dusty old book, to a hands on experience.

The Spacebridge project is run out of the Noisebridge hacker cumminity, a non-profit educational corporation for public benefit provides an infrastructure for technical-creative projects.

The Spacebridge project can be broken up into 3 parts. The payload delivery system, payload bus, and the payload itself.

The delivery system is currently a meteorological weather balloon that lofts our system about 100k feet into the air (commercial airlines fly at around 32k feet). The system also includes flight lights for increased visibility, a radar reflector dish for visibility by radar tracking systems, and a four foot parachute to help slow the decent.

The payload bus is an environmentally protecting enclosure that keeps all the payload items secure and in a known orientation and attached to necessary ports. It also protects the electronic equipment from the cold (it's around -30 degrees up there).

Lastly, we have the payload itself. We currently loft 2 cameras that have been hacked so that custom software can be run on them. We also send up an android cell phone which records accelerometer, magnetometer and GPS data, and text messages me the GPS data for our recovery. We also send up a secondary tracking system that consists of a commercial GPS tracking system, an opentracker (a custom made system to convert the GPS signals into APRS data packets) and a ham radio to transmit those data packets.

SpaceBridge comprehensive TODO list

2011-07-18T02:08:52Z

Marcus10110:

== TODO ==
* make outline of how things fit into the compartments

* assemble the antenna for GPRS

* antenna for video
** Best thing is to just have the transmitter and the antenna inside one of the compartments

* assemble GPRS GPS tracking system (details only known to Brian etc.)

* assemble and mount phone

* connect blinking circuit to the three position lights
** have Mark have a look at the circuit
** mount battery holders
** Finding about blinking circuit: It is just switching on/off two fully charged AA cells and is certainly not the best way to do it. All three LEDs on the payload are connected in parallel.

* isolate intervalometer electrically

* maybe buy Kapton tape(?)

* buy velcro for mounting electronics in box

* buy helium tank

* mount video equipment

* mount 12V power supply

* fix the position of the video camera (needs to get into launch checklist!)

* 2x cinch male-male adapters

* glue plastic sheets that came loose

* charge video battery fully and measure full voltage

* replace batteries in blinker before launch (shorting)

* replace canon camera battery

* put failed minimal launch data (track on google maps etc.) onto the wiki

* put callsign and "if found, please call XXX" onto the unit

* weight completed payload

* buy/find lithium batteries for:
** D cell for light
** AA's for LEDs
**lithium 9v for tracker

== Completed Tasks ==
* enlarge hole for video camera so that there is not plastics in the field of view

* put this list onto the wiki, also the launch prep check list

* mount canon camera to faceplate

* prepare new Y adapter (done, although the pins have to be bent a bit for safe contact!)
