Dumb Box? Make it Really Smart!Really Smart Box Featureddp2cnk

Fri, 24 Nov 2017 00:00:23 +0000

[Stephen Harrison]’s Really Smart Box is a great concept, it’s simultaneously a simple idea while at the same time being super clever. The Really Smart Box isn’t really a box; it’s a drop-in platform that can be made any size, intended to turn any dumb storage box into one that helps manage and track levels and usage of any sort of stock or consumable.

It does this by measuring the weight of the stuff piled on top of it, while also monitoring temperature and humidity. The platform communicates this information wirelessly to a back end, allowing decisions to be made …read more

Swarm of Servos Plays this Robotic GlockenspielFC639KIJA36QI9Idpsm64

Thu, 23 Nov 2017 21:01:51 +0000

It’s the happiest sounding instrument in the marching band, and it’s got the best name to boot. It’s the glockenspiel, and if this robotic glockenspiel has anything to say about it, the days of human glockenspielists are numbered.

In its present prototype form, [Averton Engineering]’s “Spielatron” looks a little like something from a carousel calliope or an animatronic pizza restaurant band. Using a cast-off glockenspiel from a school music room as a base, the Spielatron uses four mallets to play all the notes. Each key is struck by a mallet secured to a base made of two servos. For lack …read more

Glue Gun Teardown Reveals Microcontroller Mysterygluegunnerdyjb

Thu, 23 Nov 2017 18:01:42 +0000

[electrobob] got a Bosch GluePen cordless hot glue gun. The thing has some nice features — it heats up in fifteen seconds, and charges via USB, and is generally handy for those small and quick jobs that hot glue guns were made to perform. At first glance it seems like a huge improvement over the plug-in varieties, which seem to take forever to heat up when all you need is a quick dab of glue.

As cool as the product sounded, [bob] did what any right-minded hacker would do and opened it up to see how that sucker work and …read more

Building a Skyrim Quest Markerquest-marker-featurednerdyjb

Thu, 23 Nov 2017 15:01:01 +0000

I’m working on a Skyrim quest marker. You probably know what this is even if you never have played the game. When a character or location in the game relates to a quest, an arrow floats over it so you don’t miss it. If it’s a book, the book has the arrow floating over it. If it’s a person, it floats over that character’s head. It is that quest marker I aim to re-create.

I sat down in front of my sketchbook and drew the basic parameters. I wanted it to be approximately to scale to the human/elf/orc heads it …read more

Smarter Phones In Your Hacks With TensorFlow LiteTensorFlow Lite demosstevendufTensorFlow Lite architecture

Thu, 23 Nov 2017 12:00:00 +0000

One way to run a compute-intensive neural network on a hack has been to put a decent laptop onboard. But wouldn’t it be great if you could go smaller and cheaper by using a phone instead? If your neural network was written using Google’s TensorFlow framework then you’ve had the option of using TensorFlow Mobile, but it doesn’t use any of the phone’s accelerated hardware, and so it might not have been fast enough.

Google has just released a new solution, the developer preview of TensofFlow Lite for iOS and Android and announced plans to support Raspberry Pi 3. On …read more

Learn About Blockchains By Building Oneblockchain-explained-featuredjennylist

Thu, 23 Nov 2017 09:00:00 +0000

What do we curious Hackaday scribes do when we want to learn about something? First port of call: search the web.

When that something is blockchain technology and we’re looking for an explanation that expands our cursory overview into a more fundamental understanding of the basic principles, there is a problem. It seems that to most people blockchains equate to one thing: cryptocurrencies, and since cryptocurrencies mean MONEY, they then descend into a cultish frenzy surrounded by a little cloud of flying dollar signs. Finding [Daniel van Flymen]’s explanation of the fundamentals of a blockchain in terms of the creation …read more
