Meeting

  1. Milestone: Hardware order
    1. Evaluation of milestone objectives:

      1. All components except some temperature sensors are ordered.

      2. Component placement on PCB is done.

      3. The HW development took about 100h instead of the planned 60h which is due to

        • elaborate measurement capabilities (RTD and isolated thermocouple)
        • case design
        • ongoing supply chain shortages (multi changes of microcontroller module and display)

      4. The hardware milestone was narrowly missed, which has the following consequences:

        • Kernel v0.3.0 will not include any features beyond the ones specified, because some of the SW development time was allocated to HW development.
        • No additional measures have to be taken, the other milestones are still on track (mainly because the kernel is ahead of schedule).
    2. Next steps:
      1. Route remaining nets on PCB.
      2. Generate PCB design output and order PCB.
      3. Order temperatures sensors (1x RTD PT100 for in-boiler measurement and 1x K-type thermocouple for in-group head measurement).
