In 2013, I have built a satellite (WREN) which is now in orbit. There have been many hard issues to solve on the way.
This year, I am developing a simple and affordable satellite which is ready to be sent to orbit for an affordable price compared to similar sized satellites. It´s geometry complies with the PocketQub standard which is allowed to be sent to orbit as a secondary payload.
I will provide information about the satellite including schematics and source codes during the development and make it fully open hardware/open source after launch.
<Information video will follow>
TRSI is a demoscene group consisting of creative coders, musicians, graphicians and engineers who have been making cool stuff for over 30 years now.
On the WREN satellite, we put a demo for the Commodore64 computer which was downloadable from the orbit. The video is here:
This time, we will offer sceners and nerds the possibility to send a 16x16 pixel logo from space to earth. And you will need no special decoder to see it.
In fact, all you need is a DVB-T Stick and a self-made antenna, alltogether costs less than 30 USD.
You can command the satellite with an amateur radio connected to a directional antenna.
The logos and telemetry are written directly into the frequency spectrum (Hellschreiber), so everyone including governmental organizations as well as Vulcanians and Klingons will be able to see it in the 470 MHz frequency band.
I will offer devkits and ready-to-go milled parts when you don´t want to solder yourself.
There´s more to come and for sure it will be a fun challenge.
In addition to the project log I want to give some information how to overcome some hardware issues and how to interface some peripherals with an ARM controller, which may be useful also for earth-based projects.
Here is some preliminary information about small satellites and the actual TRSI project.
PS: There is another great use for this device - which is quite earth based. The board is designed for harsh environment and able to communicate over distances more than 1000km. And it gets his power via solar cells. You can for example put it somewhere in the forest to get pictures of some wild animals. And you will be able to receive the signal from as far as you can see.
A swarm of them can serve as a wide range communication network.
