Just like the garage computer explosion of the 70’s through the 80’s, which brought us such things as Apple, pong, Bill Gate’s hair, and the proliferation of personal computers, the maker movement is the new garage hardware explosion. Today, 135 million adults in the United States alone are involved in the maker movement.
Enthusiasts who want to build the products they want, from shortwave radios to personal computers, and to tweak products they’ve bought to make them even better, have long been a part of the electronics industry. By all measures, garage-style innovation remains alive and well today, as “makers” as they are called continue to turn out contemporary gadgets, including 3D printers, drones, and embedded electronics devices.
Making is about individual Do-It-Yourselfers being able to design and create with tools that were, as of a decade or two ago, only available to large, cash-rich corporations: CAD tools, CNC mills, 3D printers, low-quantity PCB manufacturing, open hardware such as Arduinos and similar inexpensive development boards – all items that have made it easier and relatively cheap to make whatever we imagine. For individuals, maker tools can change how someone views their home or their hobbies. The world is ours to make. Humans are genetically wired to be makers. The maker movement is simply the result of making powerful building and communication tools accessible to the masses. There are plenty of projects from makers that show good engineering: Take this Arduino board with tremendous potential, developed by a young maker, as example.
The maker movement is a catalyst to democratize entrepreneurship as these do-it-yourself electronics are proving to be hot sellers: In the past year, unit sales for 3D printing related products; Arduino units, parts and supplies; Raspberry Pi boards; drones and quadcopters; and robotics goods are all on a growth curve in terms of eBay sales. There are many Kickstarter maker projects going on. The Pebble E-Paper Watch raises $10 million. The LIFX smartphone-controlled LED bulb raises $1.3 million. What do these products have in common? They both secured funding through Kickstarter, a crowd-funding website that is changing the game for entrepreneurs. Both products were created by makers who seek to commercialize their inventions. These “startup makers” iterate on prototypes with high-end tools at professional makerspaces.
For companies to remain competitive, they need to embrace the maker movement or leave themselves open for disruption. Researchers found that 96 percent of business leaders believe new technologies have forever changed the rules of business by democratizing information and rewiring customer expectations. - You’ve got to figure out agile innovation. Maybe history is repeating itself as the types of products being sold reminded us of the computer tinkering that used to be happening in the 1970s to 1990s – similar in terms of demographics, tending to be young people, and low budget. Now the do-it-yourself category is deeply intertwined with the electronics industry. Open hardware is in the center in maker movement – we need open hardware designs! How can you publish your designs and still do business with it? Open source ecosystem markets behave differently and therefore require a very different playbook than traditional tech company: the differentiation is not in the technology you build; it is in the process and expertise that you slowly amass over an extended period of time.
By democratizing the product development process, helping these developments get to market, and transforming the way we educate the next generation of innovators, we will usher in the next industrial revolution. The world is ours to make. Earlier the PC created a new generation of software developers who could innovate in the digital world without the limitations of the physical world (virtually no marginal cost, software has become the great equalizer for innovation. Now advances in 3D printing and low-cost microcontrollers as well as the ubiquity of advanced sensors are enabling makers to bridge software with the physical world. Furthermore, the proliferation of wireless connectivity and cloud computing is helping makers contribute to the Internet of Things (IoT). We’re even beginning to see maker designs and devices entering those markets once thought to be off-limits, like medical.

In fact, many parents have engaged in the maker movement with their kids because they know that the education system is not adequately preparing their children for the 21st century. There is a strong movement to spread this DIY idea widely. The Maker Faire, which launched in the Bay Area in California in 2006, underlined the popularity of the movement by drawing a record 215,000 people combined in the Bay Area and New York events in 2014. There’s Maker Media, MakerCon, MakerShed, Make: magazine and 131 Maker Faire events that take place throughout the world. Now the founders of all these Makers want a way to connect what they refer to as the “maker movement” online. So Maker Media created a social network called MakerSpace, a Facebook-like social network that connects participants of Maker Faire in one online community. The new site will allow participants of the event to display their work online. There are many other similar sites that allow yout to present yout work fron Hackaday to your own blog. Today, 135 million adults in the United States alone are involved in the maker movement—although makers can be found everywhere in the world.

Expanding On The Creation Of Collapsible Containers
https://hackaday.com/2021/09/30/expanding-on-the-creation-of-collapsible-containers/
You might remember that industrial designer [Eric Strebel] tried to make a collapsible silicone container with 3D printed molds a few weeks ago, and was finally successful after dozens of attempts. Someone commented that commercial containers are molded in the collapsed position instead of the expanded position, so naturally, [Eric] had to try it once he saw the photographic proof of these molds.

Super 8 Camera Brought Back To Life
https://hackaday.com/2021/09/30/super-8-camera-brought-back-to-life/
The Super 8 camera, while a groundbreaking video recorder in its time, is borderline unusable now. Even if you can get film for it (and afford its often enormous price), it still only records on 8mm film which isn’t exactly the best quality of film around, not to mention that a good percentage of these cameras couldn’t even record audio. They were largely made obsolete by camcorders in the late ’80s and early ’90s, although some are still used for niche artistic purposes. If you’d rather not foot the bill for the film, though, you can still put one of these to work with the help of a Raspberry Pi.
[befinitiv] has a knack for repurposing antique analog equipment like this while preserving its aesthetic. While the bulk of the space inside of this camera would normally be used for housing film, this makes a perfect spot to place a Raspberry Pi Zero, a rechargeable battery, and a power converter circuit all in a 3D printed enclosure that snaps into the camera just as a film roll would have. It uses the Pi camera module but still makes use of the camera’s built in optics which include a zoom function.

https://hackaday.com/2021/10/07/microgps-sees-what-you-overlook/
GPS is an incredibly powerful tool that allows devices such as your smartphone to know roughly where they are with an accuracy of around a meter in some cases. However, this is largely too inaccurate for many use cases and that accuracy drops considerably when inside such as warehouse robots that rely on barcodes on the floor. In response, researchers [Linguang Zhang, Adam Finkelstein, Szymon Rusinkiewicz] at Princeton have developed a system they refer to as MicroGPS that uses pictures of the ground to determine its location with sub-centimeter accuracy.

Drive High-Impedance Headphones With This Stylish USB DAC
https://hackaday.com/2021/10/09/drive-high-impedance-headphones-with-this-stylish-usb-dac/
For anyone with an interest in building audio projects, it’s likely that an early project will be a headphone amplifier. They’re relatively easy to build from transistors, ICs, or tubes, and it’s possible to build one to a decent quality without being an electronic engineering genius. It’s not often though that we see one as miniaturized as [daumemo]’s USB-C DAC and headphone amplifier combo, that fits within a slightly elongated 3.5 mm jack cover as part of a small USB-to-headphone cable.
The DAC is an off-the-shelf board featuring an ALC4042 IC, it has a line-level output and a handy place to tap off a 5 volt line for the amplifier. This final part is a tiny PCB with two chips, a TPS65135 that produces clean +5 and -5 volt rails, and an INA1620 which is a high-quality audio amplifier set up for 2x gain.

Hackers And China
https://hackaday.com/2021/10/09/hackers-and-china/
The open source world and Chinese manufacturing have a long relationship. Some fifteen years ago, the big topic was how companies could open-source their hardware designs and not get driven bankrupt by competition from overseas. Companies like Sparkfun, Adafruit, Arduino, Maple Labs, Pololu, and many more demonstrated that this wasn’t impossible after all.
Maybe ten years ago, Chinese firms started picking up interesting hacker projects and producing them. This gave us hits like the AVR transistor tester and the NanoVNA. In the last few years, we’ve seen open-source hardware and software projects that have deliberately targeted Chinese manufacturers, and won. We do the design and coding, they do the manufacturing, sales, and distribution.
But this is something else: the Bangle.js watch takes an essentially mediocre Chinese smartwatch and reflashes the firmware, and sells them as open-source smartwatches to the general public.

Handheld Bandsaw Gets Standup Conversion With Scrap Lumber
https://hackaday.com/2021/10/11/handheld-bandsaw-gets-standup-conversion-with-scrap-lumber/
Handheld band saws exist, and can be highly useful tools. However, they lack some of the finesse and precision of the more traditional upright units, particularly for with smaller workpieces. [Honus] set about rectifying this, building a stand for their DeWalt handheld bandsaw out of scrap lumber.
The stand consists of some hefty wooden beams sawn to length and screwed together to make a support for the bandsaw. A nice 1/4″ thick aluminium plate is installed as a baseplate for cutting.

The M5Stack Color Maker Can Mix Paint To Match Your Subject
https://hackaday.com/2021/10/11/the-m5stack-color-maker-can-mix-paint-to-match-your-subject/
We’ve all learned in primary school art classes that blue and yellow make green, and that adding a little black to a color will make it darker. But what if you want to paint with a color that exactly matches something else? Usually, that requires a lot of trial and error (and paint), and the end result may not look the way you wanted after all.
To help aspiring artists, [Airpocket] made the M5Stack Color Maker. This is a device that reads out a color sensor and automatically mixes watercolor paint in the right proportions to match what it sensed. It dispenses drops of cyan, magenta, yellow and black paint (CMYK) into a small bowl, from which you can then apply it with a paintbrush.
The color sensor is similar in use to the color picker (or “dropper”) tool present in most graphics programs: simply point it at something that has the right color, and it will generate the correct values for you. It is based on an AMS TCS34725 color sensor, which is housed in a 3D-printed shell that also includes a white LED. The sensor outputs Red, Green and Blue (RGB) values, which are converted into the corresponding CMYK values by a Raspberry Pi Pico. A touch-sensitive screen allows the user to make adjustments before activating the paint pumps.

With this device, you can copy the color of an object or create a new color with your imagination.

Bendable Colour EPaper Display Has Touch Input Too
https://hackaday.com/2021/10/12/bendable-colour-epaper-display-has-touch-input-too/
The Interactive Media Lab at Dresden Technical University has been busy working on ideas for user interfaces with wearable electronics, and presents a nice project, that any of us could reproduce, to create your very own wearable colour epaper display device. They even figured out a tidy way to add touch input as well. By sticking three linear resistive touch strips, which are effectively touch potentiometers, to a backing sheet and placing the latter directly behind the Plastic Logic Legio 2.1″ flexible electrophoretic display (EPD), a rudimentary touch interface was created. It does look like it needs a fair bit of force to be applied to the display, to be detectable at the touch strips, but it should be able to take it.

This Homemade Mass Spectrometer Works
https://hackaday.com/2021/10/12/this-homemade-mass-spectrometer-works/
It’s not a good starter project, requiring quite a bit of sophisticated gear including two-stage vacuum pumps, Peltier cold plates, and ion sources, but if you aren’t familiar with mass spectrometers the basic idea is simple enough. You take a sample and bombard it with electrons. This creates a stream of ions of the component parts of the sample. Ions of heavy elements, obviously, weigh more than ions of lighter elements. A magnetic field deflects the ions, and the lighter ones are deflected more than the heavier ones. By detecting ions at a certain spot in the deflected beam, you can determine the relative amount of ions at a certain mass.
There are many ways you can do this, of course. But all mass spectrometers work more or less the same way with just variations on the details. In particular, [Paul’s] device uses a method to detect ions called a quadrupole mass filter. There are four parallel rods that create an RF field that oscillates.

Ring Sizes And You – A hackers approach to making rings fit on your finger
https://mclear.co.uk/2013/09/04/ring-sizes-and-you-a-hackers-approach-to-making-rings-fit-on-your-finger/
To someone that works with technology the jewelry industry is a strange beast. Each standard for measurement includes a margin of error by default. This margin of error exists due to an attempt at simplification however this simplification has removed accuracy, an engineer’s worst nightmare.
Many rings are hand polished, done on different machines that are setup slightly different. If a truly large number of rings are manufactured there could easily be an inconsistency as calibrated blanks (molds) could be used to set up each machine for each size of ring. ring size gauges also are not consistent, plastic ones deform when you push a ring on harder, and some are grooved in steps that also change accuracy from ring mandrel to ring mandrel.
Wearing Rings for newbies
If this is your first ring wearing your ring will be uncomfortable at first, be prepared for a few weeks of discomfort until eventually your finger gets used to having a new friend to build a relationship with. This relationship is a two way street, your ring gives you great power but it comes at a cost. There will be times when your ring causes you some discomfort, this is normal and expected. Your finger will begin molding itself to the ring, do not be shocked or concerned if you feel some initial discomfort, if it lasts more than a few weeks then you need a different size ring.
It’s important to get a good measurement, if your ring size is wrong your ring will be uncomfortable, a few 10th of a mm can make the difference between a ridiculously comfy experience or a finger throttling nightmare. Getting a slightly larger ring is sensible, usually by +0.4mm increase of the ID (Inner Diameter).
The size of your finger changes, be careful swimming in cold places as this is the most common place to lose rings. Cold water can decrease the size of your knuckle/finger by ~0.4mm ID (Inner Diameter) in a few seconds.
Initial Measurement – How to get it right
Using the correct Gauge tool
We strongly recommend using a “wideband gauge tool”. If you can’t access a wideband gauge tool then adding 0.4mm(~½ size US) to the ID (Inner Diameter) might be good enough. Alpha NFC ring purchasers should add 0.8mm or so. As a general rule of thumb always round up if providing your ring size in US Ring sizes. Ideally we’d of asked for your size in MM but hindsight is always 20/20.
On an average day your finger ring size will fluctuate ~0.7mm on the ID (Inner Diameter). We call this ring size deviation and it is described with the symbol ±.
Rings tend to come with either a relatively brutal square edge rim or a soft radius. Square edge rings(Rings with none or very little radius) make for a slightly less comfortable daily wear but do ensure the ring is more difficult to lose. The soft radius on the NFC ring makes the ring easier to place on your finger and also more comfortable on a daily basis.
What technology/technologies could be used to get a truly accurate measurement
High resolution 3D scanner with point of reference for scale
Kinect-esque camera and software
Note: One might also consider providing some way of measuring or controlling the state of the measurers hand IE if it’s cold or not.
What technologies can be used for a semi-accurate measurement on one axis
1080p+ Camera with a reference point such as cell phone app or magnetic strip
1080p+ Camera with well trained Haar Cascade classifiers (Machine Learning)

UV Sanitizing Autonomous Robot
Cost-effective robotic solution for surface sanitization in home
https://hackaday.io/project/181361-uv-sanitizing-autonomous-robot
Ultraviolet germicidal irradiation (UVGI) is a disinfection method that uses short-wavelength ultraviolet (ultraviolet C or UV-C) light to kill or inactivate microorganisms by destroying nucleic acids and disrupting their DNA, leaving them unable to perform vital cellular functions. UVGI is used in a variety of applications, such as food, air, and water purification, or treat biologically contaminated surfaces.
Recent studies have shown that UV short-wave radiation is capable of eliminating COVID-19, MERS, and SARS viruses at the hospital level, thus improving the cleanliness of the intensive care area, general medicine rooms and individual rooms.
This idea help us thrive in this new normal, because has cost effective, and useful to sanitize objects or the whole home by using voice commands. It’s different from other solutions because it uses the Tesla coil to turn on the UV lamp. It also uses Neural Networks, PID Controller and OpenCV.

Valve Reluctantly Shows How To Mod The Steam Deck
