👉Sigma I is ready to be pressurized for the first flight! Sigma Board 0.1 (Serial Number 001) previously on Sigma I, the tube, has been removed and will be used for the capsule instead. (1/2)
A second Sigma Board (SN 002), placed on Sigma I in A1 and A2 brackets, is in the soldering phase but will not be used for the first launch. For now, an Arduino Uno will be used to control the hatch. (2/2)
This week, we’ve received the BMP280, the last component we needed. This temperature and pressure sensor will help us know the approximative altitude of the capsule during his ascent and his descent. (1/3)
Using the NRF24l01 chip, we receive data from Sirius I (the capsule) and Sigma I (the tube) to our web panel in real-time. In the event that we lose communication between the transceiver and the capsule, we are also recording data to a microSD card. (2/3)
