Graffiti is a controversial subject, and whether you see it as art or vandalism usually depends where and how you come across it. From the scribbled tag on a house wall, to highly sophisticated murals, they tend to have one thing in common though: making a statement — whether that’s political, showing appreciation, or a […]

Musicians, makers and Arduino enthusiasts may be interested in a new project created by Max Danilin, showing a DIY automatic barrel piano, powered by an Arduino micro-controller and capable of outputing MIDI signals. A sheet is pulled under an array of 40 optocouplers using a hand crank and converted to sound using a MKR Zero
Magnets (especially those ball magnets!) are endlessly fascinating, aren’t they? It’s almost dangerous to combine them with LEDs, because how are you supposed to get anything done with something like [andrei.erdei]’s Arduino Magnetic Board beckoning from beyond your keyboard? This tons-of-fun board uses ball magnets to light up RGB LEDs as they roll around on the sexy
ARDUINO MAGNETIC BOARD IS ANYTHING BUT BORING Continue Reading
Description This is a 1×1 inch PCB module with two tiny solar cells, a highly efficient Li-Ion battery charger and with two regulated outputs (3.3V and 1.8V). It harvests enough power from indoor light to power a simple BLE or LoRa sensor. The board has castellated vias so it can be surface mount soldered onto
In this post we will learn how to create Nixie-Trilateral-Clock: While waiting for the delivery of parts for another project I decided to push ahead with this project. At its heart is two IN-13M Nixie tubes. These tubes are designed to provide a linear scale between the maximum and minimum points using an illuminated column.
While building Arduino or any other microcontroller platform project over time the need will arise to establish communication between two of the Arduino boards or microcontrollers for data exchange and/or control. This communication could be achieved using either wired or wireless process. For wireless communication between devices, quite a number of options exist including WiFi, GSM/GPRS,

Story Reflow Master really started out as a microcontroller-based graphing experiment… I wanted to visualise the temperature in my toaster oven when I manually reflowed my PCBs. I had a K-Type probe in my oven connected to my digital multimeter, and though I could see the temperature, unless I also used a stopwatch, I had

In this post, we will teach you Microphone-Sensor-With-Arduino-and-Cubesat: Mars is an awe-inspiring planet, and it is up to you to discover what is out there! We are Radiance Inc.- the team compiled of four high school physics students here to inform the world on the audible waves surrounding Mars. Our names are Becca, Kylie, Malia,
The Exen Mini was categorized as one of the world’s smallest 32-bit Arduino compatible boards that was launched by Nerdonic, although the board was able to get the job done in some areas it still had limited capacity, it had only 8 I/O pins. Based on the success and limitations of the Exen Mini, Nerdonic

Seco Embedded Creators have launched the i.MX8M based Q7-C25 and i.MX8Quad based Q7-C26. Both can run Linux and Android, and are available in 0 to 60°C and -40 to 85°C models. The 5V modules have many similar features, but the Q7-C26 based on the more powerful, up to hexacore i.MX8Quad adds some extras such as SATA III support. The Q7-C25 utilizes NXP’s dual-
