75-In-One Music

It’s likely that many Hackaday readers will have had their interest in electronics as a child honed by exposure to an electronics kit. The type of toy that featured a console covered in electronic components with spring terminals, and on which a variety of projects could be built by wiring up circuits. [Matthew North Music] has a couple of these, and he’s made a video investigating whether they can be used to make music.

The kits he’s found are a Radio Shack one from we’re guessing the 1970s, and a “Cambridge University Recording Studio” kit that looks to be 1990s-vintage. The former is all discrete components and passive, while the latter sports that digital audio record/playback chip that was the thing to have in a novelty item three decades ago. With them both he can create a variety of oscillator and filter circuits, though for the video he settles for a fairly simple tone whose pitch is controlled by an light-dependent resistor, and a metronome as a drum beat.

The result is a little avant garde, but certainly shows promise. The beauty of these kits is they can now be had for a song, and as grown-ups we don’t have to follow the rules set out in the book, so we can see there’s a lot of fun to be had. We look forward to some brave soul using them in a life performance at a hacker camp. Continue reading “75-In-One Music”

Google Lowers The Artificial Intelligence Bar With Complete DIY Kits

Last year, Google released an artificial intelligence kit aimed at makers, with two different flavors: Vision to recognize people and objections, and Voice to create a smart speaker. Now, Google is back with a new version to make it even easier to get started.

The main difference in this year’s (v1.1) kits is that they include some basic hardware, such as a Raspberry Pi and an SD card. While this might not be very useful to most Hackaday readers, who probably have a spare Pi (or 5) lying around, this is invaluable for novice makers or the educational market. These audiences now have access to an all-in-one solution to build projects and learn more about artificial intelligence.

We’ve previously seen toys, phones, and intercoms get upgrades with an AIY kit, but would love to see more! [Mike Rigsby] has used one in his robot dog project to detect when people are smiling. These updated kits are available at Target (Voice, Vision). If the kit is too expensive, our own [Inderpreet Singh] can show you how to build your own.

Tape Cutting Bot Trims The Tedium

If you have ever had to assemble a batch of electronic kits, you will know the tedious nature of cutting the tape containing your components. It’s easy enough to count four or five surface-mount resistors and snip them off with a pair of scissors once or twice, but when you are faced with repeating the task a hundred or more times, its allure begins to pale.

[Overflo] faced just such a problem when assembling hundreds of kits for a workshop at the upcoming 34C3 event in Germany. The solution? A tape-cutting robot, of course! (YouTube video, embedded below.)

At the heart of the machine is a pair of scissors operated by a stepper motor, snipping away at the component tape fed by another stepper. An infra-red light barrier sensor counts sprocket holes, and the whole is under the control of an Arduino Pro Mini. An especially clever trick is that the strip passes over a marker pen, allowing different components in a kit to be identified by a color code.

This isn’t the first such approach to this problem we’ve encountered, here’s one that cuts component tape with a laser.
