Pocket Laser Engraver.

I have been trying to get my hands on a laser cutter for some time but they always seem out of reach. All the great things that can be done with a real laser cutter tickle the imagination. I feel it's time to share my latest project - a low cost laser engraver,. The workspace is a bit small but none the less it works and comes so cheap that most will be able to replicate the result. I did take a few shortcu ...

Arduino Uno Xylophone

This xylophone uses the Arduino Uno and a multiplexer to identify when one of eight keys are struck, and play that sound via midi sound on a computer. An optional part of the instructions also allows each key to light up with two LED lights at the same time the xylophone is struck. These steps outline what I have done. Step 1: Necessary Parts Arduino Uno9 V battery with Arduino adaptorArduino to USB connect ...

3D Printed Objects that can connect to Wi-Fi without any Electronics

The world has seen an exponential growth of the Internet of things, where things are becoming connected. Every physical object is giving the chance to be connected to the internet and emit some data about itself with just the addition of some chips, and some form of wireless interface. Your Electric kettle can basically tell you when it’s ready or even prepare itself down for you. Researchers have estimated ...

How to Control a Nixie Tube With an Arduino

A Nixie Tube is a Neon gas-filled tube, that has a wiremesh anode with various cathodes shaped like numbers or symbols. Back in the 1950s they were used in computers, calculators, and laboratory equipment. Nixie tubes were replaced by LEDs and VFDs(vacuum fluorescent displays)in the 1970s. They were too costly to to mass produce so they were no longer used in most new products. Spice up your next project by ...

DIY Light (Lux) Meter using BH1750 sensor, Arduino and Nokia 5110

Introduction Hi guys, continuing on our recent path of building really cool stuffs based on the Nokia 5110 LCD display, today we will be building a DIY Lux (or light) meter using the highly sensitive BH1750 light sensor. Illuminance (measured in LUX) is the total luminous flux incident on a surface, per unit area. It is a measure of how much the incident light illuminates the surface, it is wavelength-weigh ...
