here you will find all our developments
Anything we can make public will actually be open source, so if you need anything, you need to make sure you sift through this site.
Questo è il primo concept di Athena, successivamente rimpiazzato con un modello più leggero e resistente.
Nella parte bassa vediamo una parte stampata in 3D che contribuisce ad apportare stabilità (grazie alle fins) e al contempo a dare la possibilità di avere delle clamps.

In version 2.0 the strength and weight are improved, which are acharacteristics necessary in a similar context.
The lower part has also been improved, which now implements a perfect fit with the launchpad clamps.
Sections have been opened to allow access to the on-board computers and a possible video recording or ejection of lateral parachutes, without however influencing the aerodynamic characteristics too much.
The height changes slightly. Now it allows more passive stability and more space for the parachute.
This is the very first version of the TVC developed, later replaced by V2.0 following mechanical errors due to:
low total extension
unjustified printing difficulties
Once again iterative design demonstrates how malfunction learning processes can benefit the final design.
Version 2.0 compared to the first develops:
ease and speed of printing
Thanks to Yukon Aereospace for supporting this development and providing advices.
Version 3.0 compared to the previous one develops:
even better ease and speed of printing
tailor-made for the rocket
more resistant to mechanical torsion than servomotors
removes fragile parts
This PCB board, now in its fourth iteration, is the beating heart of the stabilization and data recording system.
In fact, Andromeda is equipped with:
microcontroller with ARM Cortex-M7 processor at 600 MHz
Float point math unit, 64 & 32 bits
1984K Flash, 1024K RAM (512K tightly coupled), 1K EEPROM (emulated)
USB device 480 Mbit / sec & USB host 480 Mbit / sec
attitude control sensor
4 switchable 12V Pyro outputs to be used to power whatever you want
power supply on a quick-fit terminal block
on and off switch
LED signaling light
support for two TWM servomotors
Flash memory 128MB
Sd card reader
Double analog signal (Rx + Tx) on external pins
Additional external SPI communication pins
Additional external I²C communication pins
This PCB is the result of a week of work entirely focused on it.
In fact, it has been designed with the aim of being suitable for any need during the launch phase.
I have personally puzzled to think about what the unexpected situations could be and to develop systems that can reduce every problem, if not even prevent them, thus increasing safety exponentially.
The board has been designed to be easy to build and affordable for everyone so that, simply armed with a soldering iron, everyone can have the opportunity to build one.
All parts are through hole.
