DIY Ultraviolet Sterilization Device (UVClean)

henrydmayne

 

Introduction

Hi all and welcome to my very first instructable! In this step by step guide, you will learn how to create your very own ultraviolet sterilization device that can be used as either a wand, or as an automatic sterilization chamber. The device, called the UVClean, uses a special UVC bulb that can sterilize nonporous surfaces in a matter of minutes.

Features include:

-Sturdy and ergonomic design

-Genuine 253.7nm 3.5W UVC bulb

-Bi-color OLED display

-Passcode protected interface

-Comprehensive menu system

-Continuous handheld mode, and automatic timer mod

 2) This device is in fact a sanitizer, not a sterilizer. Sanitizing is the process of removing most organisms from a surface 99.9%, while sterilizing is the process of removing ALL organisms from a surface. This device is not medical grade, and it should not be perceived as such.

How to Make Arduino Smartwatch With Custom PCB

Hi all, in this instructable you will see how a smartwatch can be made using an Arduino board and a few other components. We are going to design and get a custom PCB fabricated which will be the motherboard of our watch housing the main circuit and the brain of the watch ATmega 328P which we will salvage from an Arduino Nano board.

I have chosen the Arduino Nano and not the more commonly used Arduino UNO because the Nano features a Surface Mount chip so it's much more compact and in this project, space is key because we need to fit all the components in the least space possible.

I am going to use a 160 mAh Li-Po (Lithium Polymer) battery which will easily be able to power the watch on regular use for at least a week which is quite good enough. We will use a USB battery charging module for charging the battery. This will also have a USB port in it to charge the battery!

I have designed the body of the watch in a 3d design software and you can easily get it 3d-printed anywhere. This was we can keep the watch completely personalised according to your need. The watch will be activated by using a push-button present at the side of the watch.

The watch will have Bluetooth functionality and will be connected to an app that can be used to track data. It can count the steps, distance and the calories burnt using an accelerometer module. With the same components and in some iterations in the code and the app, we can also easily track messages and calls received on the phone through the smartwatch! The watch will also have a heartrate measuring sensor in it which will be able to measure your pulse and I have tried it out.It's pretty accurate!

DIY Desktop 5-axis CNC Mill

i_nerantzis

OK, you bought your router and you are happy with it. If you are an artist.

But... if you are an engineer... you probably are not so happy.

You cut some 2D stuff. Then try some 2.5D and start getting excited. And then, there comes a day when you start wondering... What if I can make something more out of my 3-axis router?

Then it comes to your mind that you can always convert one of the axis from linear to rotary! Yes this is it! You start doing it... you succeed, but deep down inside you know it.

You have to go all the way to the end and do it properly. You need to make the conversion to a full 5-axis machine to be satisfied! If you feel like it, then follow my lead.

Getting set up for working from home as an electronics engineer.

Andrew Back

There are often times when it would be convenient to work from home, such as when we need to be physically present for some reason or given the current situation, when remote working might help limit the spread of coronavirus. Not to mention that it’s also handy having a setup to work on spare time projects and the inevitable, “I wondered if you could fix this?” jobs.

This post takes a look at getting a home workspace set up with the typically essential tools and equipment for working on electronics. Of course, what may be required in practice is going to vary depending upon the precise nature of the work and replicating a production line or advanced laboratory capabilities, for example, may prove a little more challenging.

Spring Making / Wire Bending Machine 

jiripraus

Well, this machine is not only about making springs. It is a wire bending machine capable of bending 0.8/0.9/1 mm wire into any 2D shape. But yeah, the coolest thing I was able to make with it so far was the spring. How cool is that?
The main goal was to make it quite precise. Other DIY wire bending machines are not very precise and their bends tend to have quite a big radius. I like to work with nice sharp bends!
The second goal was to make it as easy to build as possible with commonly available parts and components. All the structural parts are 3D printed and all the metal parts are available in most of the hardware stores.

How to Create a Large 3D Printer Using a Smaller 3D Printer - "Project Locus"redhatman  

From those that own 3D printers, to those who simply are just curious about their capabilities, one topic that comes up rather frequently is the idea of "Printing another 3D Printer". Now this may not be 100% possible when considering components such as the electronics, however, nearly every 3D printer today in the open source community utilizes to some degree, 3D printed parts in it's construction. From fan mounts to spool holders, a person can spend a few minutes searching the web, and likely find a suitable design to use on their own printer. This has proved to be very useful, especially for those who love to build, modify, and design their own machines.

Benchtop Micro Milling MachineHonus  

This is a micro sized benchtop mill that is suitable for milling small parts in soft metals such as Aluminum and Brass. While it is a manual mill it wouldn't be too difficult to convert it to CNC by adding suitable stepper motors and a CNC controller. 

The travel specs are:
X axis- 150 mm
Y axis- 75 mm
Z axis- 150 mm 

This design uses off the shelf assembled linear slides and 80/20 Aluminum extrusion for simple assembly and accurate alignment. The beauty of this design is its modular nature- you can make it any size you want and it's super easy to build.

What are we building?

Humans can't detect magnetic fields, but we use devices that rely on magnets all the time. Motors, compasses, rotation sensors, and wind turbines, for example, all require magnets for operation. This tutorial describes how to build an Arduino based magnetometer that senses magnetic field using three Hall effect sensors. The magnetic field vector at a location is displayed on a small screen using isometric projection.

What is an Arduino?

An Arduino is a small open-source user-friendly microcontroller. It has digital input and output pins. It also has analog input pins, which are useful for reading input from sensors. Different Arduino models are available. This tutorial describes how to use either the Arduino Uno or the Arduino MKR1010. However other models can be used too.

Evezor: Open Source SCARA Robot ArmJeremy S. Cook

Per this project’s Kickstarter video seen below, when 3D printing first jumped came into the mainstream, many people thought they could now make anything they wanted, perhaps even many of them to sell with no human interaction. While true in some sense, these machines do require human intervention between prints, and can take a very long time to produce useful parts. Additionally, some designs may require a different tool, such as a laser cutter or CNC router. That, of course, means more space and money, and still there is the issue of machine tending.

SCAD to STL – How to Convert SCAD Files to STLBenjamin Goldschmidt 

SCAD and STL files are two common file types for 3D design applications. SCAD stands for “Solid Computer Aided Design”, and the file format is used to describe 3D objects. It was pioneered by a software called “OpenSCAD,” which is a free CAD software for designing 3D objects. STL stands for “stereolithography” and is a popular file type to use with slicers for 3D printing.
The main difference between these two file types is in the way the models are described in code. In STL files, the 3D model is created using a “tiled” set of triangles along the surface of the object. This creates a fully 3D object. In contrast, SCAD files design an object using mathematical relationships. For example, a cube-like object can be described using its length, width, and height. This type of design can be useful for printing objects such as fractal art on objects.
Because the geometry used by STL files is more capable of conforming to complex designs, you may find you want to convert SCAD to STL. Lucky for you, there are two really easy ways to do this.

A Super-Material You Can Make In Your Kitchen (Starlite?)

NightHawkInLight

In this video I attempt to recreate a lost supermaterial called Starlite. This material could supposedly resist temperatures up to 10,000 degrees Celsius, having undergone testing by NASA and the Atomic Weapons Establishment in the UK. I believe in this video I have come close in function to the original formula for Starlite, but there is still some work to be done. My result works very well, but for a few reasons I may talk about in a future video I do not believe Starlite used PVA glue as it's binder, and I also suspect a different CO2 producer was used instead of baking soda. More experiments are required.

EduExo is a DIY exoskeleton kit
Arduino Team

You’ve seen exoskeletons in movies such as Aliens and Iron Man, and perhaps even heard about current experiments with human use. Unfortunately though, if you want to learn about this technology, the barrier to entry is very high.
EduExo, now available on Kickstarter, is an attempt by robotics researcher Volker Bartenbach to bring this technology to the masses. Based on an Arduino Uno, the device takes the form of an upper and lower arm cuff, along with a motor and force sensor to allow it to be used for haptic control.

How to build a cool & cheap 3D printed micro drone
Jan Olejnik

Radio controlled drones are extremely popular and you can get them in all shapes and sizes. In recent years, one specific type of drone has seen a sudden rise in popularity: micro quadcopters. They fit in your palm but can be powered by high-RPM brushless motors and a two-cell Li-Po battery, so they have, potentially, tons of power. Combine it with first-person video transmission and you have one amazing toy that’s nearly indestructible. And today, we’ll demonstrate that RC vehicles and our 3D printers are a perfect match! We’re going to tell you how to build a cheap, yet powerful, 3D printed mini quadcopter suitable for both indoor and outdoor flying thanks to its diagonal size of 90mm (measured from the motor to motor).
