There are various ways to measure plant health, and we’ve seen many projects creating open-source solutions. One we haven’t seen is a dendrometer, which involves measuring various physical dimensions of trees to track their health and growth. [John Opsahl] is changing this with the OpenDendrometer, a tool for tracking the diameter of tree limbs and fruit. […]

In a continuation of Clem Mayer’s previous project, he’s now adding Wi-Fi connectivity for starting prints wirelessly from anywhere. Outdated technology The advent of USB and Wi-Fi-enabled printers is still quite recent. Before they were released to the market, these devices could only communicate over far more primitive data links. The classic parallel port is

Like artificial intelligence, speech synthesis was one of those applications that promised to revolutionize computing in the 1980s, only to fizzle out after people realized that a robotic voice reading out predefined sentences was not actually that useful. Nevertheless, computer manufacturers didn’t want to miss out on the hype and speech synthesizers became a relatively

The widespread adoption of the CAN bus (and OBD-II) in automobiles was largely a way of standardizing the maintenance of increasingly complicated engines and their needs to meet modern emissions standards. While that might sound a little dry on the surface, the existence and standardization of this communications bus in essentially all passenger vehicles for
Sometimes you need to display a number nice and large, making it easily readable at a good distance. [Lewis] has just the thing for that: a big expandable 7-segment display. The build is modular, allowing it to be extended from 2 to 10 digits and beyond. The digits themselves are made of 3D-printed parts assembled onto
YOU CAN BUILD A GIANT 7-SEGMENT DISPLAY OF YOUR VERY OWN Continue Reading
This grid of letters is a puzzle game for tablet devices called Ruzzle. The contraption attached is an automated solver which uses LEGO Mindstorm parts to input the solutions on the screen. [Alberto Sarullo] is the mastermind behind the project. As you can seen in his demo video after the break he has a flair for the
Instructables member AGBarber has created a fantastic measuring tool in the form of a Arduino powered digital tape measure called the DMW. Which cannot only measure distances on surfaces but can also be used to calculate the diameter of pipes and features a useful tachometer. Check out the video below to learn more about the project and how you can easily create your
The official team of developers and engineers creating the Arduino range of microcontrollers and boards have this week introduced a new Nano Screw terminal adapter designed to help you speed it your prototyping efforts. The handy little add-on board is now available to purchase from the official Arduino store priced at $36 for a pack of three boards. Quick
A Jack-In-The-Box is scary enough the first time. However, if you’ve seen the clown pop out before, it fails to have the same impact. [Franklinstein] decided that swapping out the clown for an alternative payload would deliver the fright he was after. Inside the toy, an Arduino Nano runs the show. It’s paired with an airhorn, installed in

Makers, electronic enthusiasts and those interested in building robots may be interested in a new robotic arm project featured on the Instructables website created by Maurizio Miscio. The robot arm is controlled using a touchscreen application loaded onto an old smartphone hose inside a control box, making the design of the robotic arm completely self-contained. “In order
