question we set Gareth Halfacree, and the result is a fascinating feature
(page 36). Gareth looks at options as diverse as full storage cache (where
you keep the whole operating system in RAM), through to image and
video processing, training machine learning models, and setting up dual-
head workstations. There’s also an interview with Eben Upton (page 42)
which looks at the march into 64-bit processing at Raspberry Pi.
We’ve had another high-end launch recently, too. Last month we just
caught the release of the High Quality Camera. This month we’ve had a
chance to look at it in a little more detail, and we’ve got some projects
for you to look at, along with a guide to making a Raspberry Pi digital
SLR-style case (page 66).
If you’re new to Raspberry Pi, we
have a lot to get you started. From the
best robot kits (page 78) to learning
Python (page 80), and a huge range of
inspirational projects starting on page 12.
Let us know what you plan to make
with an 8GB Raspberry Pi and High
Quality Camera?
