spacedos03's Introduction

SPACEDOS03 - semiconductor-based ionizing radiation spectrometer

Build firmware

SPACEDOS03A front panel

SPACEDOS03 is an open-source semiconductor particle detector (dosimeter and spectrometer) for space applications. The detector is based on a silicon PIN diode. The Detector is designed as autonomous for long-term measurement campaigns and therefore contains its power source from high-capacity battery cells and a recording medium in the form of an industrial SD card. The device is designed to be able to work for half a year continuously.

The detector is mounted into a 3D-printed box that contains positions for passive TLDs and track detectors. The main purpose of the device is experimental testing of radiation shielding materials in the real environment.

Parameters

  • Silicon PIN diode detector with 44 mm³ detection volume

  • Effective number of energy channels 470 ±3

  • Deposited energy ranges from 60 keV to 7 MeV

  • Energy measurement resolution 15 ±2 keV (depending on calibration method and type of particles)

  • Power supply 18650 Li-ion cells

  • Integration time depends on firmware setup

  • Data storage device: Industrial SLC SDcard

  • Dimensions - 120 x 90 x 62 mm

  • Weight - 447 grams (with SAFT batteries)

  • Power module

spacedos03's Issues

Sticker texts

Text "Do not press here", should be explained by the exact value of maximal force. e.g 10 N.

Cap printing

Model víčka momentálně nevyužívá tiskovou fintu se zaslepenou dírou. Tudíž je otvor pro šroub neoptimálně vytištěný a bortí se.

Improvement of automatical firmware build workflows

Aktuálně vkládání git commitu do firmware funguje způsobem, že máme naincludovaný soubor, do kterého se zapíše aktuální commit. Příkaz arduino-cli compile má mít parametr -D, který umí do kódu zahrnout definici. Takže by se informace o commitu nebo například o datu/čase kompilace mohlo dostávat do firmware formou definice.

https://arduino.github.io/arduino-cli/0.29/commands/arduino-cli_compile/

Uvnitř zdrojového kódu by pak mělo být něco jako:

  #ifndef GIT_HASH
  #define GIT_HASH "manual_build"
  #endif

A skrze github actions by se tam hodnota hashe dostávala pomocí parametru build-properties.
