Inside a Dutch Street Organ: The Art of Mechanical Music-Making

https://invidious.privacyredirect.com/watch?v=KG_k6iyC2ME

[James]’ Mechanical Organ of Dutch origin has been around longer than he has, but thanks to being rebuilt over the years and lovingly cared for, it delivers its unique performances just as well as it did back in the day. Even better, we’re treated to a good look at how it works.

The organ produces music by playing notes on embedded instruments, which are themselves operated by air pressure, with note arrangements read off what amounts to a very long punch card. [James] gives a great tour of this fantastic machine, so check it out in the video embedded below along...

Frigate with Hailo for object detection on a Raspberry Pi

I run Frigate to record security cameras and detect people, cars, and animals when in view. My current Frigate server runs on a Raspberry Pi CM4 and a Coral TPU plugged in via USB.

Raspberry Pi offers multiple AI HAT+'s for the Raspberry Pi 5 with built-in Hailo-8 or Hailo-8L AI coprocessors, and they're useful for low-power inference (like for image object detection) on the Pi. Hailo coprocessors can be used with other SBCs and computers too, if you buy an M.2 version.

AsteroidOS 2.0 open-source smartwatch OS released, now supports around 30 devices

AsteroidOS 2.0 Linux-based, open-source smartwatch operating system has just been released with features such as always-on display support, Tilt-to-Wake, a customizable QuickPanel, multiple launcher styles, Nightstand mode, performance improvements, and support for about 30 devices. It’s been a long journey. We first noted the open-source project in 2016 when Florent Revest showcased a basic user experience on the LG G Watch, just before giving a talk at FOSDEM 2016 introducing AsteroidOS. This was followed by the launch of the Connect Watch (crowdfunded) AsteroidOS smartwatch in 2017 by a French company (which didn’t get funded), and AsteroidOS 1.0 was released in 2018....

60W Pocket Cloud is a microSD card reader with USB PD passthrough for your smartphone (Crowdfunding)

60W Pocket Cloud is a microSD card reader with 60W USB PD passthrough for your smartphone that works with Android (USB-C) and iOS (USB-C or Lightning) mobile devices, as well as other hosts with a spare USB port. Once upon a time, smartphone manufacturers would include a microSD card socket in their devices, but those have now become harder to find. If your device’s spare storage is getting dangerously low, you’d need to either purchase cloud storage or connect a microSD card reader to the USB-C port of your phone. The latter works, except you can’t charge your phone when...
