[Old] Alastair Roberts ☛ I Built a Synth for My Daughter
TLDR: I built a portable step-sequencer synthesizer for my daughter’s third birthday. It has four sliders that control four notes in a looping sequence. Slide up = higher pitch, slide down = lower.

Hackaday ☛ Hackaday Podcast Episode 348: 50 Grams Of PLA Hold A Ton, Phreaknic Badge Is Off The Shelf, And Hackers Need Repair Manuals
Join Hackaday Editors Elliot Williams and Tom Nardi as they go over their picks for the best stories and hacks from the previous week. Things start off with a warning about the long-term viability of SSD backups, after which the discussion moves onto the limits of 3D printed PLA, the return of the Pebble smart watch, some unconventional aircraft, and an online KiCad schematic repository that has plenty of potential. You’ll also hear about a remarkable conference badge made from e-waste electronic shelf labels, filling 3D prints with foam, and a tiny TV powered by the ESP32. The episode wraps up with our wish for hacker-friendly repair manuals, and an interesting tale of underwater engineering from D-Day.

CNX Software ☛ Edgi-Talk machine learning development kit features Infineon PSOC Edge E84 Edge Hey Hi (AI) SoC (Crowdfunding)
Edgi-Talk is a machine learning platform/development kit powered by an Infineon PSOC Edge E84 Arm Cortex-M55/M33 SoC featuring Arm Helium, an Arm Ethos-U55 micro NPU, and an ultra-low-power NNLite neural network accelerator, all of which enable AI/ML processing at varying power/performance levels. The devkit also comes with 128 MB PSRAM, 128MB QSPI flash, a 4.3-inch capacitive touchscreen display, two digital microphones, a speaker, WiFi 6 and Bluetooth LE 6.0 wireless connectivity, motion and environmental sensors, as well as a 40-pin Raspberry Pi header and two PMOD connectors for expansion.

CNX Software ☛ ExtrudeX machine recycles failed/old 3D prints into new filament (Crowdfunding)
When 3D printing, users will always waste filament one way or the other, either due to a failed print or because of the support for the print, and there may also be test/old prints that you don’t need/use anymore, for example, a retraction cube or a benchy. That means all that material usually ends up in the dustbin. Priyank Pal, founder of Creative3dp, did not like all that waste, so he created the ExtrudeX machine to recycle 3D print waste and filament scraps back into usable filament. On top of that, the machine itself is 3D printable and much more affordable than commercial solutions from companies such as Filabot. I’d usually provide the specifications here, but as a crowdfunded project, the ExtrudeX’s full technical details are not fully available.

Raspberry Pi ☛ The 6th edition of our Beginner's Guide is available now!
It was just over two years ago that we introduced the 5th edition of The Official Raspberry Pi Beginner’s Guide. That edition featured the latest and greatest of our hardware and software at the time: Raspberry Pi 5 and Raspberry Pi OS Bookworm. Since then, we’ve released many shiny new things, and the time was right for a major update. The 6th edition is available now, featuring Raspberry Pi 500 and 500+, and Raspberry Pi OS Trixie. We’ve also incorporated numerous improvements, clarifications, and corrections.
