Temperature Sensor And Indication using the CP Sapling

With our new CP Sapling, there is a world of possibilities that you can explore with the SAMD21 microcontroller. And thanks to the hard work of Adafruit, there is a ton of great examples that can be used to explore microcontroller functionality and make a few cool projects to impress your family this holiday season!

As always before we get started, if you have never used a CircuitPython board like the QT PY, be sure to check out Adafruit’s learning site to quickly get started with your new board. –> Adafruit Learning Site: Getting Started With CircuitPython

Open Source CAD devroom for FOSDEM

Interested joining the open source CAD devroom during (virtual) FOSDEM in February?

The call for participation closes on Sunday, December 20th:

[FOSDEM] Open Source Computer Aided Design and Modeling devroom at FOSDEM 2021

We are pleased to announce the CfP for the Open Source Computer Aided
Design and Modeling devroom at FOSDEM 2021, on Sunday, 7 February 2021.

We hope you’ll join us for a full day of talks, demos and interesting
discussions on designing, modeling and testing hardware using Open
Source tools. This year’s event will be fully virtual and will feature
multiple channels for talks, Q&A as well as hallway discussions.

We welcome any talk proposals about the creation of physical objects.

Can You Use an Easy-Bake Oven for Reflow Soldering?

The answer is yes, yes you can. As long as you have one made after about 2011, at least. In the video after the break, [Blitz City DIY] takes us briefly through the history of the venerable Easy-Bake Oven and into the future by reflow soldering a handful of small blinky boards with it.

Precursor: open hardware RISC-V mobile dev kit

⌛️ Today is the last day of the Precursor 📱🛠️✨ campaign by the wonderful bunnie and xobs on Crowd Supply:

Precursor: Mobile, Open Hardware, RISC-V System-on-Chip (SoC) Development Kit

Made For a Lab. Fits in a Pocket. Verifiable by Design.

Precursor is an open hardware development platform for secure, mobile computation and communication. This pocket-sized device accommodates a built-in display, a physical keyboard, and an internal battery while remaining smaller and lighter than the average smartphone. Precursor was built for use on the road, but it compromises nothing as a development platform. Powered by an FPGA-hosted, soft-core System-on-Chip (SoC), it gives developers the freedom to inspect, verify, and customize nearly every aspect of its operation. Help us take those critical first steps toward a world in which silicon-level trustworthiness is attainable.

Trust It. Because You Can, Not Because You Have to.

We are accustomed to accepting the word of large corporations, like Apple and Google, that our gadgets are trustworthy. Without any hard evidence, we’ve long had to take in on faith that our privacy is being respected and that our personal data is not just one backdoor away from being stolen, exploited, or exposed. (We’ll go ahead and leave “monetized” off that list, since we all know that’s happening.) We’ve had to accept this reality in large part because we’ve had no other choice. Precursor changes the status quo by making evidence-based trust a core principle of its design. We have subjected every aspect of this platform to a level of scrutiny that will allow users to trust their devices. You, the user, will be able to trust Precursor based on scientific evidence that is observable without access to a million-dollar microscope.

Situating Precursor Within the Device Ecosystem

We are the first to admit that Precursor isn’t for everyone. It’s a new class of development platform, made for security- and privacy-critical applications. We know it’s not going to replace your smartphone today. Rather, we see it as an indicator of good things to come from the open hardware ecosystem.

Two New Oddly Specific Objects from Joey Castillo

Tom Fleet writes on Hackster about one of our favorite makers:

Joey Castillo’s No Muppet When It Comes to Time Management, Back with Two New Oddly Specific Objects

One of the first significant projects I was fortunate enough to be able to cover was that of the OSO Open Book, an Oddly Specific Object from Joey Castillo. This open source e-book reader looked to free many from the bindings of DRM, enforced by many commercial platforms.

Bert and Ernie

The latest pair of PCB designs to be derived from Castillo’s Twitter feed come in the format of this illustrious duo, affectionally named Bert and Ernie.

I think all I can say — without being sued — is that the resemblance to a certain well-known set of characters who may or many not resemble the duo heading up this article is, well, uncanny.

Right now, this platform looks set to perform as the prototype from which future works can spring forth, and as with a lot of what Castillo does, it’s all about testing out new technologies and ideas, and there are one or two features on these fresh new designs that are pretty damn funky — let’s check ’em out.

Holiday with Hackaday and Tindie

Exciting news from Hackaday and Tindie:

2020 can’t stop this holiday meetup! Join Hackaday and Tindie virtually for a fun community hangout in Remo.

Some of you may remember this platform from the community Bring-A-Hack at Remoticon last month. For those who have not used Remo, it’s  a neat platform that allows participants to move around a virtual conference space and join different conversations. The holiday event will accommodate seating areas for up to eight people as well as smaller seating sections.

Register ahead of time here!

Join the fun December 15th Noon Pacific!

Share your latest projects, check out what other people in the community are working on, and catch up with friends! We hope to see you there!

Link to join the event once it has started.

What’s the Value of Hackable Hardware, Anyway?

Great post from one of our favorite hardware hackers, bunnie, on Crowd Supply:

What’s the Value of Hackable Hardware, Anyway?

There is plenty of skepticism around the value of hackable products. Significantly, hackability is different from openness: cars are closed-source, yet support vibrant modding communities; gcc is one of the “real OG”s of open source, but few users find it easy to extend or enhance. Is it better to have a garden planted by the most knowledgeable botanists and maintained by experienced gardeners, or an open plot of land maintained by whoever has the interest and time?

In the case of hardware products, consumer behavior consistently affirms a strong preference for well-curated gardens. Hardware is hard – not only is it difficult to design and validate, supply chains benefit from economies of scale and predictable user demand. The larger a captive audience, the more up-front money one can invest into developing a better hardware product. However, every decision to optimize comes with inherent trade-offs. For example, anytime symmetry is broken, one must optimize for either a right-handed or a left-handed version.

For Apple, true “courage to move on and do something new that betters all of us” was to remove the headphone jack, which resulted in locking users deeper into a walled-garden ecosystem. For hackers like myself, our “courage” is facing blunt criticisms for making “ugly” products with screws in order to facilitate mods, such as braille keyboards, in order to expand the definition of “all of us” beyond a set of privileged, “perfect” users.

I hope this braille keyboard is just the first example of many mods for Precursor that adapt the product for unique end-users, bucking the trend of gaslighting users to mold their behavior and preferences to fit the product. If you’ve got an itch to develop your own yet-to-be-seen feature in a mobile device, please visit our crowdfunding campaign page to learn more about Precursor. We’re close to being funded, but we’ve only a few days left in the campaign. After the campaign concludes on December 15th, the limited edition will no longer be available, and pricing of the standard model goes up. If you like what you see, please consider helping us to bring Precursor to life!
