Hackaday Links: December 8, 2019

Now that November of 2019 has passed, it’s a shame that some of the predictions made in Blade Runner for this future haven’t yet come true. Oh sure, 109 million people living in Los Angeles would be fun and all, but until we get our flying cars, we’ll just have to console ourselves with the ability to “Enhance!” photographs. While the new service, AI Image Enlarger, can’t tease out three-dimensional information, the app is intended to sharpen enlargements of low-resolution images, improving the focus and bringing up details in the darker parts of the image. The marketing material claims that the app uses machine learning, and is looking for volunteers to upload high-resolution images to improve its training set.

We’ve been on a bit of a nano-satellite bender around here lately, with last week’s Hack Chat discussing simulators for CubeSats, and next week’s focusing on open-source thrusters for PocketQube satellites. So we appreciated the timing of a video announcing the launch of the first public LoRa relay satellite. The PocketCube-format satellite, dubbed FossaSat-1, went for a ride to space along with six other small payloads on a Rocket Lab Electron rocket launched from New Zealand. Andreas Spiess has a short video preview of the FossaSat-1 mission, which was designed to test the capabilities of a space-based IoT link that almost anyone can access with cheap and readily available parts; a ground station should only cost a couple of bucks, but you will need an amateur radio license to uplink.

We know GitHub has become the de facto standard for source control and has morphed into a collaboration and project management platform used by everybody who’s anybody in the hacking community. But have you ever wished for a collaboration platform that was a little more in tune with the needs of hardware designers? Then InventHub might be of interest to you. Currently in a limited beta – we tried to sign up for the early access program but seem to have been put on a waiting list – it seems like this will be a platform that brings versioning directly to the ECAD package of your choice. Through plugins to KiCad, Eagle, and all the major ECAD players you’ll be able to collaborate with other designers and see their changes marked up on the schematic — sort of a visual diff. It seems interesting, and we’ll be keeping an eye on developments.

Amazon is now offering a stripped-down version of their Echo smart speaker called Input, which teams up with speakers that you already own to satisfy all your privacy invasion needs on the super cheap — only $10. At that price, it’s hard to resist buying one just to pop it open, which is what Brian Dorey did with his. The teardown is pretty standard, and the innards are pretty much what you’d expect from a modern piece of surveillance apparatus, but the neat trick here involved the flash memory chip on the main board. Brian accidentally overheated it while trying to free up the metal shield over it, and the BGA chip came loose. So naturally, he looked up the pinout and soldered it to a micro-SD card adapter with fine magnet wire. He was able to slip it into a USB SD card reader and see the whole file system for the Input. It was a nice hack, and a good teardown.

Forty Four Hackers And A Hatch: Progress Egress Takes Off

The 50th anniversary of the first Moon landing is rapidly approaching, and uber space-nerd Adam Savage is in the thick of the celebration of all the amazing feats of engineering that made humanity’s first steps out of the cradle possible. And in a grand and very hacker-friendly style, we might add, as his Project Egress aims to build a full-scale replica of the Apollo 11 Command Module Columbia’s hatch.

Life On Contract: Product Development Lessons Big And Small

Developing a product and getting it out there to build a business is really hard. Whether it’s a single person acting alone to push their passion to the public, or a giant corporation with vast resources, everyone has to go through the same basic steps, and everyone needs to screw those steps up in the same way.

The reality is that the whole process needs to involve lots of aspects in order to succeed; small teams fail by not considering or dedicating resources to all of those aspects, and large teams fail by not having enough communication between the teams working on those pieces. But in truth, it’s a balance of many aspects that unlock a chance at a successful product. It’s worth recognizing this balance and seeking it out in your own product development efforts, whether you’re a one-engineer juggernaut or a large, established company.

Friday Hack Chat: How Do You Collaborate With Hardware?

The world of Open Source software is built on collaboration. In one corner of the world, someone can fix a bug in a piece of software, and push it up to the gits. In another part of the world, someone else can put that fix into the next release, and soon everyone has newer, better software. The Internet, or the ability to rapidly transmit text and binary files, has made this all possible.

Hardware is another story. There’s a financial barrier to entry. Not only do you need a meter and a good iron, you’re probably going to need oscilloscopes, logic analyzers, and a bunch of other expensive tools. You’ll need to buy your BOM. If you’re using a PIC, it might be a good idea to buy the good compiler. Hardware is hard and expensive, and all those software devs who complain don’t know what they’re talking about. Collaborating on hardware is much more difficult than pushing some code up to the cloud.

For this week’s Hack Chat, we’re going to be talking about collaborating on hardware projects. This is a deep dive on how to make collaboration with physical objects work, and this week we’re going to be learning from some of the best.

Our guests for this week’s Hack Chat are Pete Dokter and Toni Klopfenstein of SparkFun Electronics. Pete is formerly the Director of Engineering at SparkFun and now the Brand Ambassador for SparkFun Electronics. He hosts the According to Pete video series expounding on various engineering principles and seriously needs a silverburst Les Paul and a Sunn Model T. Toni is currently the product development manager at SparkFun. She’s served on the Open Source Hardware Association Board and participates in the Open Hardware Summit yearly. In her free time, she spends fifty weeks out of the year finding dust in her art and electronics projects.

During this chat, we’re going to be discussing what makes a collaborative hardware project, how to make distributed development work for your team, and the limits of what you can do with several hardware engineers separated by thousands of miles. This is a hard problem, much harder than a distributed team of software engineers, and a fantastic discussion for all.
