A $1, Linux-Capable, Hand-Solderable Processor
Over on the EEVblog, someone noticed an interesting chip that’s been apparently flying under our radar for a while. This is an ARM processor capable of running Linux. It’s hand-solderable in a TQFP package, has a built-in Mali GPU, support for a touch panel, and has support for 512MB of DDR3. If you do it right, this will get you into the territory of a BeagleBone or a Raspberry Pi Zero, on a board that’s whatever form factor you can imagine. Here’s the best part: you can get this part for $1 USD in large-ish quantities. A cursory glance at …read more
3D Printing in Metal: the Laser and Metal Powder Printers We Saw at IMTS
Last week I went to the International Manufacturing Technology Show (IMTS) and it was incredible. This is a toy store for machinists and showcases the best of industrial automation. But one of the coolest trends I found at the show are all the techniques used to 3D print in metal. The best part is that many of the huge machines on display are actually running!
It’s probably better to refer to this as additive manufacturing, because the actual methods can be significantly different from your 3D printer. Below you’ll find examples of three different approaches to this process. I had …read more
Exploring an Abandoned Toys “R” Us
If someone asked me to make a list of things I didn’t expect to ever hear again, the question “Do you want to go to a Toys “R” Us?” would be pretty near the top spot. After all of their stores (at least in the United States) closed at the end of June 2018, the House of Geoffrey seemed destined to join Radio Shack as being little more than a memory for those past a certain age. A relic from the days when people had to leave their house to purchase goods.
But much to my surprise, a friend of …read more
This Xbox 360 is Powered by Steam
Now that we’re far enough into the next generation of home video game consoles that we can’t really keep calling them that anymore, yard sales are sure to be full of lonely Xbox 360s and PS3s that have been put out to pasture. You’ll probably even find a Wii U or two out there that somebody accidentally purchased. This is great for hackers who like cramming new electronics into outdated consumer gear, and accordingly, we’re starting to see the fruits of that generational shift.
Case in point, this Xbox 360 which has been transformed into a “Steam Box” by [Pedro …read more
AI Finds More Space Chatter
Scientists don’t know exactly what fast radio bursts (FRBs) are. What they do know is that they come from a long way away. In fact, one that occurs regularly comes from a galaxy 3 billion light years away. They could form from neutron stars or they could be extraterrestrials phoning home. The other thing is — thanks to machine learning — we now know about a lot more of them. You can see a video from Berkeley, below. and find more technical information, raw data, and [Danielle Futselaar’s] killer project graphic seen above from at their site.
The first FRB …read more
