10 more killer Raspberry Pi projects (Collection 2) via Network World

Another great collection of Raspberry Pi projects to get you going. Some of my favorites include a Rubik’s Cube Solver, a flying drone with a Raspberry Pi for a brain and  Pi-based Information Dashboard that can also control your home automation devices. — Douglas

Killer Raspberry Pi ProjectsIn the last installment of Killer Raspberry Pi Projects, the focus was on projects that produced a final device or system. In this installment, I’m going to cover a few cool projects along with some tools used to build other projects. I've also included some Raspberry Pi Zero projects that are becoming more numerous as the board and its successor, the Raspberry Pi Zero W, become more available (the latter is still much like hens' teeth).

64 Online Resources to Learn to Code for Free via Business Insider

My goal in life is ABL — Always Be Learning. Here are 64 sites to help you get coding today. Add some more skins to your career toolkit. — Douglas 

If you’re brand new to the world of web design and web development, it makes sense to get started learning to code by utilizing all the free resources available online. This way, you can discover what you like (and more importantly don’t) before financially investing in a certain set of courses.

However, there are so many free resources, classes, and books to pick from! It’s easy to become overwhelmed. (Ever hear of too much of a good thing?!)
To make things easier, I compiled a list of 64 FREE web design and development resources. The list is based on a previous article I wrote for Learn To Code with Me. However, it has since been updated and expanded to include more resources. It is a compilation of courses, written tutorials, blogs, YouTube channels, ebooks, online communities, and even in-person workshops
.

Arduino Rain Sensor Module Guide and Tutorial via Henry's Bench

Another great component to add to your weather station. Use it to track weather data, automate sprinkler systems and more! — Douglas


This module allows you measure moisture via analog output pins and it provides a digital output when a threshold of moisture is exceeded.
The module is based on the LM393 op amp.
 
It includes the electronics module and a printed circuit board that “collects” the rain drops.  As rain drops are collected on the circuit board, they create paths of parallel resistance that are measured via the op amp.

Portable Arduino Lab via hyperRitual

What a great idea and a great way to make use of these older electronics kits. I would love to do this with my Arduino Yun as it has built-in wifi and a Linux computer that can bridge with the Arduino to allow easy access to Internet of Things (IoT) projects and use all the components of these electronic kits. — Douglas

I have hot-glued my Arduino Duemilanove to the battery compartment lid of my Maxitronix 500-in-One electronics lab, making for a portable Arduino lab that includes:

  • 8 LEDs
  • Photo-transistor
  • CdS cell
  • Antenna coil
  • Tuning capacitor
  • DPDT swtich
  • 665-hole breadboard
  • 8 SPST switches
  • 8-digit LCD display
  • 7-segment LED display
  • 4-bit embedded microcomputer w/ keyboard
  • Speaker
  • Transformer
  • 50kΩ and 100kΩ potentiometers
  • Compartments and trays for loose components

The Arduino aligns with the spring terminals of the 7-segment display, such that the case closes perfectly.

Rash of in-the-wild attacks permanently destroys poorly secured IoT devices via Ars Technica

While I’m all for taking basic security precautions with IoT devices, this seems way over the top. Send me a note. Drop me an email. Don’t just zap my Arduino or Raspberry Pi and leave me wondering what happened. Ouch! Prepare yourself and your IoT devices so you don’t get burned. — Douglas

Researchers have uncovered a rash of ongoing attacks designed to damage routers and other Internet-connected appliances so badly that they become effectively inoperable.

PDoS attack bots (short for "permanent denial-of-service") scan the Internet for Linux-based routers, bridges, or similar Internet-connected devices that require only factory-default passwords to grant remote administrator access. Once the bots find a vulnerable target, they run a series of highly debilitating commands that wipe all the files stored on the device, corrupt the device's storage, and sever its Internet connection. Given the cost and time required to repair the damage, the device is effectively destroyed, or bricked, from the perspective of the typical consumer.

PIR Motion Detector With Arduino (simple and Easy Demostration) via Instructables

A quick lesson on using a motion sensor with your Arduino. A great learning exercise that gives you a good "jumping off" point for more Arduino exploration -- Douglas



in the following video we are going to see how we can integrate the passive infra red sensor or simply PIR sensor with an arduino uno board and how you can get seral data through it.the pir sensor basically works on the thermal radiation which are being emitted by the body of humans as well as animals.

New Book – The Hardware Hacker: Adventures in Making and Breaking Hardware – by Bunnie Huang via Adafruit Industries

One for my “To Read” shelf. — Douglas

For over a decade, Andrew “bunnie” Huang, one of the world’s most esteemed hackers, has shaped the fields of hacking and hardware, from his cult-classic book Hacking the Xbox to the open-source laptop Novena and his mentorship of various hardware startups and developers. In The Hardware Hacker, Huang shares his experiences in manufacturing and open hardware, creating an illuminating and compelling career retrospective.
Our very own LadyAda (Limor Fried, founder and engineer of Adafruit) scored a review copy and even gives her recommendation on the back cover! Here’s what she had to say:

“Bunnie is the ultimate tour guide of hardware hacking as it stands today, with an eye towards the sublime art of how things are really made. The Hardware Hacker will take you on a journey through the factories of the world, covering both technical & ethical implications of the ‘stuff’ we manufacture and buy.”

Nifty MIT Software Lets You Design and Test Your Very Own Drone via WIRED

Want to geek out on drones? Here is a cool project from MIT that will allow you design your own drones with a variety of options. Complete software coming in June 2017. — Douglas

Now, anyone who knows which end of a screwdriver to hold can design a drone and test it virtually using software developed at MIT’s Computer Science and Artificial Intelligence Laboratory and test it virtually. “It can help you explore and try different shapes and different controllers,” says Tao Du, who led the nine-month project.

How to make a gigantic Arduino via Boing Boing

This would be great for Arduino education events and classes. Make it easy to see how everything connects and operates without crowding everyone around a tiny Arduino Uno or giving each group its own board. — Douglas

My friend John Edgar Park made a huge Arduino for demo purposes. He brought it to Maker Faire a few years ago and it was a big hit. He finally got around to writing a tutorial for building your own.

Perpetual Clock With Arduino via Instructables

No matter what Deepak Chopra tells you, time is linear. Hopefully this clock is a little closer to reality than the circular ones we're all used to. The five minute intervals feel less neurotic than being precise down to the minute, and each number is magnified, reminding you to focus on the present.

I made this using just about every machine at Pier 9 (waterjet, sand blaster, laser cutter, 3D printer, electronics lab, etc.). It's made of 6061 aluminum, steel hardware (screws, nuts, bearings), 3D printed gears, an Arduino Uno, and the hour and minute panels are laser cut / etched plywood.

Noted: Biomed Shield for Arduino 101 Powered By Intel

Allows students, educators, and hobbyists to learn about biomedicine by monitoring heart rate, temperature, and other physiological metrics.

The Biomed Shield for the Arduino 101 Powered by Intel is a fully-featured shield for demonstrating the principles of Biomedical Instrumentation. The shield allows the user to measure a few physiological metrics such as heart rate, breathing rate, body impedance, body temperature, etc. The shield is a work-in-progress. I still have a ways to go before I'm really satisfied with it. But this is a good pause point to show off what I've done thus far.
