Raspberry Pi Weekly Issue #539 - Hey Hi (AI) at the edge and a celebrity 3D print
Hands up if you know what Dijkstra’s Algorithm is… Howdy, A brand-new episode of the Raspberry Pi Podcast just dropped, and in it, we explore how well Raspberry Pi runs Hey Hi (AI) at the edge, enabling a variety of use cases in the field (sometimes in a literal field). We also learnt what Dijkstra's algorithm is and how it can be used to traverse a treasure map. A new batch of products joined the Powered by Raspberry Pi roster this summer.

Raspberry Pi ☛ SPOKE: An RP2040-powered touch controller
A shiny CD-sized disc with a cardboard sleeve featuring colourful fantasy artwork, the SPOKE could easily be mistaken for an album by a 1990s indie band. The main difference is that it has 27 holes around its perimeter, each surrounded by a copper oval: these are capacitive touch pads. It also features a USB-C port, a reset button, and an RP2040 microcontroller chip.

Hackaday ☛ Music Is Back On Optical Disk In This Plex Server
Given that the no doubt totally sustainable build-out of data centers has sent both solid state and magnetic hard drive prices soaring, though, [WNY Over The Air] decided to take a look back at optical disks — specifically the high-density BDXL disks — and see how they do hosting the music library for his Plex server, among other things.

Hackaday ☛ Hacking A $6000 Cotton Candy Machine To Fully Control It
We previously covered the journey in getting the vending machine back into a state where it’d actually reliably produce cotton candy again, a process which is quite tedious and temperamental. After a lot of fiddling with sensors and temperature settings this was fixed, but still left the issue that as a vending machine it should allow the owner to set prices and such. Sadly this could only be done remotely via a special account, which access to had been left with the previous owner.
