Building Pi with Pi

Raspberry Pi's profits are up. So is its DRAM bill

The AI gold rush is proving good for Raspberry Pi's bottom line, but it's also forcing the low-cost computer maker to borrow money to keep enough memory chips in stock. In a trading update published on Friday, Raspberry Pi said it expects full-year earnings to come in significantly ahead of market expectations after a stronger-than-expected first half driven by healthy demand, higher average selling prices, and the benefit of lower-cost memory inventory purchased earlier. Raspberry Pi...

UK's Raspberry Pi shares hit record as industrial demand boosts outlook

UK's Raspberry Pi shares hit record as industrial demand boosts outlook June 5 : Britain's Raspberry Pi on Friday upgraded its full-year profit outlook, sending shares of the single-board computer maker to an all-time high. The Cambridge-based company said strong pricing and demand from industrial customers helped it weather soaring memory-chip costs, though its profitability per unit would moderate in the second half as the inventory of chips secured at lower prices begins to shrink....

UK's Raspberry Pi lifts annual profit forecast on strong first-half results

UK's Raspberry Pi lifts annual profit forecast on strong first-half results June 5 : Single-board computing company Raspberry Pi on Friday raised its full-year 2026 profit forecast, saying strong AI-related demand was expected to result in adjusted core profit "significantly ahead" of market expectations for the year. The company expects first-half core profit of at least $38 million, with unit shipments of over 4 million for the six months ending June 30. The performance is likely to be...

$\pi$Creds: Privately Inferred Credentials

arXiv:2606.03771v1 Announce Type: new Abstract: Decentralized verifiable credential systems have seen limited deployment in practice. Existing constructions, built on zero-knowledge proofs, are complex, application-specific, and largely restricted to predicates over structured data. We present Privately Inferred Credentials ($\pi$Creds): privacy-preserving, legacy-compatible, decentralized verifiable credentials generated by trusted LLM inference over authenticated data.

PI-JEPA: Label-Free Surrogate Pretraining for Coupled Multiphysics Simulation via Operator-Split Latent Prediction

Announce Type: replace-cross Abstract: Reservoir simulation workflows face a fundamental data asymmetry: input parameter fields (geostatistical permeability realizations, porosity distributions) are free to generate in arbitrary quantities, yet existing neural operator surrogates require large corpora of expensive labeled simulation trajectories and cannot exploit this unlabeled structure. We introduce \textbf{PI-JEPA} (Physics-Informed Joint Embedding Predictive Architecture), a surrogate...

Scheduling Analysis of UAV Flight Control Workloads on PREEMPT_RT Linux Using a Raspberry Pi 5

arXiv:2604.19275v2 Announce Type: replace Abstract: Modern UAV architectures increasingly aim to unify high-level autonomy and low-level flight control on a single General-Purpose Operating System (GPOS). However, complex multi-core System-on-Chips (SoCs) introduce significant timing indeterminism due to shared resource contention. This paper performs an architectural analysis of the PREEMPT RT Linux kernel on a Raspberry Pi 5, specifically isolating the impact of kernel activation paths...
