Deimos DAQ, the open-source precision data acquisition and controls platform, is a step closer to production-ready!
The order is out for the first two units of the enclosure, complete with powdercoat and graphics.

InterpN is getting B-splines, and a 3x speedup at the same time!
Implementing B-splines exposed some opportunities for optimizations in the existing cubic Hermite methods, especially for larger data. Now, all InterpN cubic methods, both Hermite and B-spline, are at least 3x faster than scipy even asymptotically for large data, and >10x faster for latency-dominated small samples.

InterpN's B-splines also parallelize the linear solves for spline coefficients. While it's still slower to initialize a spline than a stateless interpolator like a cubic Hermite, this still brings it close to a linear thread speedup when d…
InterpN B-splines show massively improved numerical error compared to scipy - about 6-8 orders of magnitude better for typical use-cases.
InterpN B-splines will also include a no-alloc linear solve for the spline coefficients using pre-sized scratch space, so it can be initialized in a bare-metal no-std environment.

Cool part of the day: single-supply high-common-mode (1.7kV cont. 6kV for 60s) isolated instrumentation amp! Super neat that this is possible with so few passives.
Gain error and input offset specs aren't amazing, but it's hard to get ever…
Deimos DAQ Rev 7 is out for fabrication!
This version adds an insulation displacement cable header breakout for a panel mount dsub-25 connector, 6 more channels (4 GPIO output, 2 input), layout improvements to reduce radiated emissions, a…
Routed the RMII traces on IN2 and re-oriented the ethernet PHY to keep the traces shorter and cleaner.
I might regret co-routing the traces this tightly, but as far as external emissions go, this should quiet things down.
Back to the bench! Using a Deimos DAQ to tune a solenoid valve driver. Too low frequency, and it will chatter; too high, and it will dissipate heat unnecessarily.
This plot shows the ideal range of frequency starts just above 3500Hz, where…
