Hackaday Links: November 20, 2016

Posted on by

The Raspberry Pi 2 is getting an upgrade. No, this news isn’t as big as you would imagine. The Raspberry Pi 2 is powered by the BCM2836 SoC, an ARM Cortex-A7 that has served us well over the years. The ‘2836 is going out of production, and now the Raspberry Pi foundation is making the Pi 2 with the chip found in the Raspberry Pi 3, the BCM2837. Effectively, the Pi 2 is now a wireless-less (?) version of the Pi 3. It still costs $35, the same as the Pi 3, making it a rather dumb purchase for the …read more

Add Robotic Farming to Your Backyard with Farmbot Genesis

Posted on by

Growing your own food is a fun hobby and generally as rewarding as people say it is. However, it does have its quirks and it definitely equires quite the time input. That’s why it was so satisfying to watch Farmbot push a weed underground. Take that!

Farmbot is a project that has been going on for a few years now, it was a semifinalist in the Hackaday Prize 2014, and that development time shows in the project documented on their website. The robot can plant, water, analyze, and weed a garden filled with arbitrarily chosen plant life. It’s low power …read more

Raspberry Pi 3 Gets USB, Ethernet Boot

Posted on by

The Raspberry Pi is a great computer, even if it doesn’t have SATA. For those of us who have lost a few SD cards to the inevitable corruption that comes from not shutting a Pi down properly, here’s something for you: USB Mass Storage Booting for the Raspberry Pi 3.

For the Raspberry Pi 1, 2, Compute Module, and Zero, there are two boot modes – SD boot, and USB Device boot, with USB Device boot only found on the Compute Module. [Gordon] over at the Raspberry Pi foundation spent a lot of time working on the Broadcom 2837 used …read more

Hackaday Prize Entry: An Internet Of Things Microscope

Posted on by

For their entry into the Citizen Scientist portion of the Hackaday Prize, the folks at Arch Reactor, the St. Louis hackerspace, are building a microscope. Not just any microscope – this one is low-cost, digital, and has a surprisingly high magnification and pretty good optics. It’s the Internet of Things Microscope, and like all good apparatus for Citizen Scientist, it’s a remarkable tool for classrooms and developing countries.

When you think of ‘classroom microscope’, you’re probably thinking about a pile of old optics sitting in the back of a storage closet. These microscopes are purely optical, without the ability to …read more

ArduCAM Introduces A Third Party Raspberry Pi

Posted on by

There are hundreds of ARM-based Linux development boards out there, with new ones appearing every week. The bulk of these ARM boards are mostly unsupported, and in the worst case they don’t work at all. There’s a reason the Raspberry Pi is the best-selling tiny ARM computer, and it isn’t because it’s the fastest or most capable. The Raspberry Pi got to where it is today because of a huge amount of work from devs around the globe.

Try as they might, the newcomer fabricators of these other ARM boards can’t easily glom onto the popularity of the Pi. Doing …read more

Hackaday Prize Entry: A Raspberry Pi Project

Posted on by

There’s no piece of technology that has been more useful, more influential on the next generation of sysadmins and engineers, and more polarizing than the Raspberry Pi. For $35 (or just $5), you get a complete single board computer, capable of running Linux, and powerful enough to do useful work. For the 2016 Hackaday Prize, [Arsenijs] has created the perfect Raspberry Pi project. It’s everything you expect a Pi-powered project to be, and more.

While the Raspberry Pi, and the community surrounding the Raspberry Pi, get a lot of flak for the relatively simple approach to most projects which are …read more
