We are clearly owed an update on the status of the Demo units - as clearly it was announced on the 10th March Annual Report: see extracts below

To comply with continuous disclosure we would have to been advised if deliveries were delay or the packaging could not go ahead. But as always AKP and FB drag out every announcement to the last minute

"The successful integration and packaging of the MEMS
transducer, together with our proprietary ASIC controller,
enabled countless advancements in algorithms, signal
processing, and multichip functionality, as well as the
design and production of the electronic circuitry and
software required to demonstrate and operate the
devices outside of the cleanroom. Our current packaging
capabilities and capacity will be further augmented later
this quarter as EarthMountain brings their dedicated chip
packaging capabilities online."
"Ongoing influence of the global COVID‑19 pandemic
throughout the period negatively impacted the
countless engineering tasks and timelines associated
with the aforementioned accomplishments. This was
most consequential in preventing direct and hands‑on
interaction with vendors, subcontractors and customers
that are traditionally utilized for effective collaboration.
Contending with this reality is the impetus behind the
decision to expedite production and engage in the design
and fabrication of systems that permit demonstration
devices and systems that can be independently operated
and assessed by customers and market influencers.
These systems are for the most part completed and
awaiting production chips, anticipated by the vendor to
be supplied prior to the end of Q1‑22.
