Collaborate Disseminate
If you’ve got a few self-designed PCBs under your belt, you probably know the pain of missing some little detail and having to break out the bodge wires to fix it. So we feel for [Arsenio Dev], who placed an SD card slot next to an SoC, only to find …read more
Once upon a time, small Linux-capable single board computers were novelties, but not anymore. Today we have a wide selection of them, many built around modules we could buy for our own projects. Some of the chipset suppliers behind these boards compete on cost, others find a niche to differentiate …read more

It’s understood that 3D printers and CNC machines need to control motors, but there are a few other niceties that are always good to have. It would be great if the controller board ran Linux, had support for a nice display, and had some sort of networking. The usual way of going about this is either driving a CNC machine from a desktop, or by adding a Raspberry Pi to a 3D printer.
The best solution to this problem is to just drive everything from a BeagleBone. This will give you Linux, and with a few motor drivers you can …read more

It was announced a day or two ago, but now the PocketBone has made its first real-world appearance at the World Maker Faire in New York this weekend. This is a tiny, tiny Linux computer that’s small enough to fit on a keychain, or in an Altoids mini tin. It’s only $25 USD, and from the stock lists on Mouser and Digikey, there are plenty to go around.
The specs for the PocketBeagle are more or less exactly what you would expect from any BeagleBone. There’s an ARM Cortex-A8 running at 1GHz, 512 MB of RAM, and SD card storage. …read more
The BeagleBone famously fits in an Altoids tin. Even though we now have BeagleBone Blacks, Blues, and Greens, the form factor for this curiously strong Linux board has remained unchanged, and able to fit inside a project box available at every cash register on the planet. There is another Altoids tin, though. The Altoid mini tin is just over 60×40 mm, and much too small to fit a normal size BeagleBone. [Michael Welling] has designed a new BeagleBone to fit this miniature project box. He’s calling it the Pocketbone, and it’s as small as the mints are strong.
The Pocketbone …read more
The ESP-32 is the Next Big Chip. This tiny microcontroller with WiFi and Bluetooth is the brains of the GameBoy on your keychain, emulates an NES, and does Arduino. There are ESP32 modules that are somewhat easy to acquire, but so far the bare chips have been unobtanium. Now you can buy them. One supplier has them for $3.60 USD/piece. That’s a lot of computational power, WiFi, and Bluetooth for not much money. What are you going to build?
What is the power of artisanal product videos? The argument for this trend cites [Claude C. Hopkins] and how he told …read more
