Are you interested in carillons? Would you like to play your own music on a carillon? Don’t wast your time in boring exeperiments with paper, squares and scissors, build your first Arduino-powered hole puncher!
The following tutorial demonstrates how to interface multiple DS18B20 on a single bus with Arduino and get temperature readings from each of them. This feature can be a huge advantage when you want to control many DS18B20s distributed over a large area. More info Build it yourself Boards, sensors and kits for projects like this…
Cosmos enthusiast Jason Bowling’s come up with a very straightforward way of focusing his Celestron 127SLT with a Raspberry Pi Zero SBC. “One of the tradeoffs with the mid-price Celestron 127SLT is that it shakes rather badly when you touch it, and takes several seconds to settle down. I’m focusing using a Bahtinov mask and…
Bulgaria-based Olimex, which is known for its open spec OLinuXino SBCs like the Allwinner A64 based A64-OLinuXino, is shipping its open source, Alwinner A64 based Teres-A64 laptop kit, with an 11.6-in LCD, 2GB RAM, 16GB eMMC, 9500mAh battery, and an Ubuntu Mate OS. Instead of using the A64-OLinuXino SBC, Olimex designed a custom, irregularly shaped mainboard that…
Created by engineer Joel Moritz Jr, the Cthulhu Shield is a new open source sensory substitution and sensory augmentation development kit for Arduino. The device takes the form of an Arduino Uno or Mega shield, with a strange flexible electrode setup that is placed directly on the user’s tongue, in order to augment the perception of one…
Numerical control(also computer numerical control, and commonly called CNC) is the automated control of machining tools (drills, boring tools, lathes) and 3D printers by means of a computer. A CNC machine processes a piece of material (metal, plastic, wood, ceramic, or composite) to meet specifications by following a coded programmed instruction and without a manual…
Developing a robot with a computer brain requires a bunch of software tools on the computer side—like software drivers, third party tools for computer vision and simulation tools. ROS framework, , the Robot Operating System, gathers all these tools and manages how you develop a code for your robot. The concept of ROS goes far…
