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

 Aarav G

Tinkercad Projects »

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.

3D Printable Robotic Actuator

seanhodgins

Upon research for an upcoming project, I discovered this simple way to make very tiny magnetic actuators. RC enthusiasts have been using these for some time now, but they don't seem very well known. I think there are a lot of useful applications for these little actuators, and they are simple enough to be designed by anyone, which means easy to implement in custom projects. Follow along in the video as I show you how to make the one designed and I will explain how it works. Although I have provided the files to 3D print my design, I encourage you to try and design your own!

Versatile Press / Brake and More..

Tuomas Soikkeli

Hi!
This is my instructable about making a press. And some usefull attachments for it.
Instructable includes plans. Structure is tested with 8 ton jack.
With 6 ton jack, frame keeps it shape without any bends.
Welds are made with 3.25mm Esab ok 73.15 welding rod. I used 110 a current.
I made my press with little different way.
Jack is placed down...
It lowers the center of gravity and places the handle at a height where you can bare down instead of pulling down. Its easier to make different attachments to it, for bending, rolling etc.
..Or up.
To get more power for stamping and punching steel.
I made an attachment to mount 8 ton jack to the upper bar.

I've become fascinated with those X-Ray Videos of working Mechanisms, and so, I wanted to make some MDF cut plates of them, just for fun.
So, I went to the Net to search for some 3D Files, but the ones I've found are crap, either Homemade Firearms, or 3D for movies, so I went to do them from scratch.
Here's my tips on how to do it;

Battery Cases for Electronic Kits.

liquidhandwash

If you have built one of the cheap electronic kits featured in my previous instructable, you probably want to put in some sort of case. Having your project in a nice looking case will really make your project look great and will impress your friends much more than a naked PCB with wires and a battery hanging off it. Your project should be something you can be proud of, take to a job interview and say look what I made!
This instructable will show you whats possible with a little thought and a laser cutter.
There are four types of cases shown here,

•  Case without a battery or switch: The easiest to make but you will need to run a lead to your power supply.
•  Case with a battery: Great if your kit has a switch.
•  Case with a battery and switch: The most challenging to build, but some kits don't have a switch.
•  Case with a push button, battery and switch.

97 Examples of Tech-Free Toys

Katherine Pendrill

From DIY Paper Box Puppets to Wooden Coloring Books

While miniature robots and app-controlled playthings may be on the rise, there is still a growing demand from consumers for simple tech-free toys that allow children to embrace their imagination. Made from minimalist materials and featuring straightforwards designs, these timeless toys prove that children don't necessarily need the latest high-tech products.
For boys, there are a number of tech-free toys that are heavily focused on building. For example, there are home-inspired wooden building blocks, cardboard architecture kits and paper-based medieval toys, all of which offer boys the possibility of building their own creations from simple and uncomplicated materials.
For girls, these tech-free toys offer creative and artistic options that go beyond traditional plastic dolls. Some of the most innovative toys for girls are empowering coloring books, DIY paper doll crafts and miniature felt garden play sets. Despite their simplistic design and lack of smart technology, these tech-free toy options for girls are extraordinarily imaginative and highly educational.

The amazing science behind HP’s new full-color 3D printers

Garage Staff

Today, HP unveiled its groundbreaking low-cost, full-color 3D printers at the annual SOLIDWORKS World 3D design and manufacturing trade event. The new HP Jet Fusion 300/500 printers are an industry first: capable of creating production-quality prototypes quickly, accurately and affordably — making advanced 3D technology accessible to a wider swath of digital innovators. And this huge leap forward in 3D printing began as HP explored a surprising realm of light — one that we’re unable to see.
Cheryl MacLeod, HP’s Global Head of 3D Fusion Science, leads the team of scientists and engineers at HP’s 3D Open Materials and Applications Lab in Corvallis, Oregon who are charged with developing the science behind the company’s portfolio of 3D printing materials. “We ultimately think of printing as a way to convey information,” says MacLeod. “And with 3D color printing, we now have an entirely new language.”
Breakthrough 1: Seeing the light
In developing the new Jet Fusion technology, HP’s 3D R&D teams called on the company’s deep expertise in the science of ink to create black fusing agents able to absorb heat at greater speeds, as is needed for 3D printing. But printing color with exclusively black agents isn’t possible, so a new solution needed to be found.

The new HP Jet Fusion 300/500 printers are an industry first: capable of creating production-quality prototypes quickly, accurately and affordably.
HP’s scientists realized that they needed a primer coat of white on the outer layers of the black parts being produced so that color could be applied and fused. But how could you create a layer of white when all available fusing agents were black? A new kind of fusing agent was needed, so that the surface of the fused part remained white, but absorbed heat as well as black. And they found the answer in an unexpected realm of light — one that we’re unable to see.

Vacuum Forming Rig
stechi

 I wanted to produce a vacuum forming machine that would allow me to do small parts, just for experimenting. I wanted to go for a self-contained unit with its own heater and vacuum pump. I know you can do a lot with an oven and vacuum cleaner, but my challenge was to do something neater than that, a self-contained machine.
I won’t go into how vac forming works, because there are plenty of explanations on the internet. But the main concerns are to hold the plastic sheet, to heat it, to hold it on an airtight moulding table (platen) and to reduce the air pressure to make the moulding. In short, the heater softens the plastic sheet that is held in the frame. Then the frame is lowered onto the platen, where the object is. The vacuum pump underneath then draws out the air under the sheet so that the plastic forms the shape of the object; it cools and the job is done.

Low-cost desktop injection moulding

Janie Barrett

Low-cost desktop injection moulding - here, Mitchell Brown from VERT Design, explains how they did it using Asiga's desktop 3D printing solution ...
Our product design company was engaged to develop a variation of a hose clip that is used on a high speed production line. The product works through the use of an integral hinge and flexible clipping geometry.
Traditionally we would test the design through the used of SLS 3D printed models, however, the results achieved were not accurate. We required the geometry to be proven in the actual production materials, which in this case was injection moulded polypropylene
Through the design phase, we developed multiple iterations. Eventually this was short-listed to two possible concepts. Producing a prototype tool in steel or aluminium would have cost many thousands of dollars and taken a minimum of 6 weeks. We turned to 3D printed tooling as it was faster and cheaper.

The Easy Way to Design Gears in Fusion 360

Desktop Makes

One of the first things I ever made from a 3D printer was a gear. But it wasn't just any old gear. The beauty behind this gear was that it was a replacement part for the very printer that was making it. This still blows my mind to this day. I love printing gears and still get excited about this new world that 3D printers have opened up. The problem is that designing gears have always been a bit of a challenge for me. That is until I learned what I'm about to teach you.
In the last step I also include a video demonstrating the entire process.
