creating a product; his SAMD51-based PyCorder
sensor gadget was quickly stifled when he found
that obtaining more than the 15 SAMDs he’d used
for prototyping was not going to be possible until
2023. Until then, Joey had relied on just-in-time
ordering, knowing that whatever he desired was
just two days away via Digi-Key.
For his Open Book project, Joey has stopped
chasing SAMDs and switched to the Raspberry
Pi Pico, which can be soldered straight to his
updated board thanks to its castellated edges.
And instead of worrying about battery charging
ICs, he redesigned the Book to use ordinary AAA
batteries. In addition to embedding multiple
footprints to accommodate equivalent available
parts, Joey has begun exploiting every peripheral
of his microcontrollers before reaching for a
separate dedicated component. Forged in the
flames of the pandemic, Oddly Specific Objects
now designs their products, like the LCD
FeatherWing, with minimization of supply chain
impacts in mind. In an uncertain and scarce
world, it’s best to keep things simple.
SURVIVAL OF THE FLEXIBLE
Predicting the future was never easy, but the
challenges of recent years have made even
reasoning about tomorrow impossible at times.
The overarching sentiment of the folks we spoke
to was that nobody has a firm grasp on what
the future may hold, and the best approach is to
adapt within the parameters that you can control
and bend with the changing winds.
