Do you dominate the Arduino technology? If you do not dominate it is probably because it is dominating you.
Knowing Arduino is the first step for you to create various types of technologies, so the first step is for you to master the full operation of an Arduino board.
In this Instructables you will learn step by step to master the complete circuitry of an Arduino compatible board.
Belt 3D printers are just now starting to hit the market and Infinity3D is a new option with an extra trick up its sleeve.
Most 3D printers’ build volume is a function of their size. To get a bigger bed, you need longer X and Y axes rails. To print taller parts, you need longer Z axis rails. There are exceptions, such as SCARA robots equipped with extruders, but even those have limits. Belt printers are unique in that they can print parts of infinite lengths — at least in one axis. Such printers are just now starting to hit the market and Infinity3D is a new option with an extra trick up its sleeve.
PicoLight is a minimalist adjustable light for low-light photography, based on the Raspberry Pi Pico.
One of the activities I really enjoy while working on a new project is documenting it. I love getting creative while taking pictures of the process and of the final products. A thing that has been really handy in this process is an adjustable studio light, which I use to add a bit of colour to the background (that’s why most of the pictures in these tutorials are purple hehe).
PicoLight is a smaller version of a classic studio light that is useful for playing with colours in low-light shots or for coloured shadows photography.
Simple yet colorful project makes full use of the ESP32’s processing power, that bright display, and the on-board microphone.
Former Microsoft programmer and father of the Windows Task Manager Dave Plummer has been looking into embedded projects of late, turning the M5StickC into a colorful live-view audio spectrum analyzer — running at 30 frames a second.
If you’ve ever tried to document a project on your workbench with photos or videos, you know the challenge of constantly moving tripods to get the right shot. [Mechanistic] is familiar with this frustration, so he built a small desktop camera crane.
This video show you step by step how to use 75mV Shunt Resistor to measure DC current of up to 500A using Arduino.

After visiting the large graffiti walls near his workshop in Berlin, Niklas Roy wanted to get involved by constructing a machine that can do the painting for him. In its most basic form, the system — which Roy calls the Graffomat — consists of two axes that work together to paint either vector or raster images.

In this video we will be having a look at a very versatile component, the TL431 IC. I used it in the feedback loop of my DIY switched mode power supply and thus got interested in it. That is why I will show you how it works, how you can use it in lot of different circuits and also how it functions in feedback loops of for example voltage converters. Let’s get started!
Designed with modularity in mind, this build wasn’t exactly straightforward — and Kent discusses the troubleshooting stage in detail.
Engineer Sam Kent has designed a modular Eurorack-compatible stereo DJ mixing system, featuring XLR and line-level outputs, a cuing system, and volume meters.
“Inspired by Eurorack modular synthesizers and the boutique mixer market, the project aims to design and build a simple and customisable DJ mixer,” Kent explains. “The design is op-amp based, with filters implemented as 12db/oct active inverting filters, 10k ohm output impedances, and buffered potentiometers acting as voltage dividers for the controls.”
What just happened? A hacker appears to have leaked the entirety of livestreaming service Twitch, from the source code and user payouts to encrypted passwords. It’s recommended that all users change their passwords, enable two-factor authentication, and reset their stream key.
A 4Chan user posted the 125GB torrent link on the forum earlier today, saying it was to “foster more disruption and competition in the online video streaming space” because “their community is a disgusting toxic cesspool.”
