VFD displays are beloved for their eerie glow that sits somewhere just off what you’d call blue. [mircemk] used one of these displays to create an old-school VU meter that looks straight out of a 1970s laboratory. The build uses an Arduino Nano as the brains of the operation, which uses its analog inputs to process […]

Always wanted to have a graphical weather station? And with accurate sensors? Maybe this project is something for you. With this weather station you can see what the weather is “doing”. Temperatures for example might rise or fall. From a normal thermometer it is not possible to see the temperature history. With this weather station

Here comes a simple Graphic Equalizer showing 14 audio bands from 60Hz up to 16kHz. It consist of a PCB based on MSGEQ7 and ESP dev board. Since a MSGEQ7 chip recognizes 7 bands only and an ESP dev board gives us a chance to read a single analog input only, there was a trick

Variations II of Variations II is a kinetic sculpture inspired by John Cage’s Variations series. Cage’s Variations II is a graphical composition that generates musical events using measurements of distance between dots and lines on a piece of paper. The instructions for the piece determine the behavior of rotating panels and images synchronized to be

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

The main objective of this project is to show how to interface a uCAM-II serial camera to 4Duino. uCAM-II is a highly integrated micro serial camera which could be controlled by any host that requires a video camera or a JPEG compressed still camera for embedded imaging applications. uCAM-II processes various features making it trivial

Introduction: Like many out there, I enjoy a good exercise session, whether it be indoors or outdoors. As part of that I purchased a Polar branded heart rate monitor, which came with a “Wearlink” chest strap and RS300Xsd receiver watch. The watch is able to do quite a bit of analysis on its own, in

The DMM (digital multimeter) is a basic measurement tool for nearly every electrical engineer and many other engineers. With the push to constantly improve power efficiency in electronic designs comes a need to not only measure voltage and current, but to dynamically see them as well. Keithey’s DMM7510 combines a 7½-digit DMM with an 18-bit,

In this project, I am using an Arduino board to show forecast of the weather from Google Weather service on a VGA screen. The display is obviously graphical one, with icons and some colorful text. It is one of those gadgets I wanted to have for some time now – A weather forecasting display that
