Arduino RGB Color Mixer

A fun, interactive project for makers new to Arduino. Control the brightness of an RGB LED with Potentiometers, with on/off switch built in.

ABOUT THIS PROJECT

Who is this for?: This RGB LED color mixer project is perfect for the beginner Arduino user who is keen to try an build an interactive gadget this is not only fun and easy to make, but could be useful for anyone who uses RBG colors, such as artists, web developers and interactive lighting controllers.

What is does: This simple circuit combines three potentiometers to set the brightness for each of the red, green and blue LED’s inside an RGB LED.

A pushbutton switch is added an an extra feature to turn the circuit on and off.

How do I build it tho? Wire the diagram as shown in the schematics. The RGB Led is wired to PMW pins 9, 10 and 11 on the Arduino. The pushbutton is connected to pin 7 and the 3 potentiometers to A0, A1 and A2. Remember to add a 10K ohm pull up resistor to the ground connection on the pushbutton. For an explanation as to how this works, check out here https://playground.arduino.cc/CommonTopics/PullUpDownResistor

Also make sure to connect 3 220 ohm resistor’s between the LED and the output pins, this will ensure your LED does not burn out.

The value of each Potentiometer is printed to the serial monitor, so if you are fiddling with the LED and find a color you like, you can record the RGB value to use later.

Once you have the circuit wired up and the sketch uploaded, try turning the knobs on the potentiometers. Nothing should happen at first until you hit the button. Now try turning the knobs again. The led should now light up. Time to play with light! Remember RGB light is not like mixing paint. when all the potentiometers are on full, the light should be white. Try leaving one of the potentiometers off or very low, and varying the other two.

An extension to this project would be to hard code some RBG values for particular colours you like, and add some more push buttons which, when pressed, would set the RGB LED to those colours. Feel free to share the code if you try an extension like this!

Enjoy!

int blue = 9; // Define Digital Pins for each colour of the LED
int green = 10;
int red = 11;

int redPot = A0;
int greenPot = A1; //Define Analog Pins for the 3 potentiometers
int bluePot = A2;


int greenVal = 0; //Create a variable to store the state of each Potentiometer
int blueVal = 0;
int redVal = 0;

const int BUTTON = 7; //Define the button Pin
int state = 0;    //Create a variable to store wether button is on or off
int val = 0;      //Create a variable to store the momentary state of the button
int old_val = 0;  //create a variable to store the previous state of the button

void setup() {
  // put your setup code here, to run once:

    delay(10);                      
  }

  old_val = val;                            // Save the previous button reading to compare next time through loop

  greenVal = analogRead(greenPot);          //Read the position of the potentiometers
  blueVal = analogRead(bluePot);
  redVal = analogRead(redPot);

  if (state == 1) {                         //If button is on, set the state of each LED according to position
    analogWrite(green, greenVal / 4);       //of its correspoding potentiometer. Anolog inputs range from 0-1023,
    analogWrite(blue, blueVal / 4);         // while anolog outputs as PMW can be from 0-255. Therefore we must
    analogWrite(red, redVal / 4);           // divide the potentiometer readings by 4 to set the state correctly
    
    Serial.print("RGB(");
    Serial.print(redVal/4);

    Serial.println(")");
    
    delay(50);
  } else {                                   // If button is off, set all LED's to LOW/off

Affiliate Marketing: As Cost Effective As It Gets

Pay-per-click (PPC) advertising – like Google Adwords and Facebook – are getting more expensive all the time. While we invest heavily in Google Adwords ourselves here at LeadDyno, I can tell you that our click costs are constantly creeping up. Which means that next month, I know we’ll have to pay a little bit more to get the same results. Our affiliate program, on the other hand, is always profitable… because we pay our affiliates a commission based on the sales they bring us. Until they sell something, we don’t have to pay them anything. Affiliate marketing is also more scalable than pay-per-click (PPC) marketing. While there are a fixed number of relevant keywords that we (and you) can bid on and make money, there’s basically an unlimited amount of product that you can sell with affiliate partners.

A Quick “Plug and Play” With Your E-Commerce Provider

As you probably know by now, most affiliate tracking software is pretty complex to get setup! You won’t have any setup issues with LeadDyno. We designed it to be really easy to integrate with your website. Many of our E-Commerce integrations are “one-click.” For example, if you’re a Shopify store owner, you simply enter the URL of your store, give LeadDyno permission to connect with it, and you’re done. You simply do this once, and you’re ready to start rolling out links and marketing materials to your affiliates! We also provide complimentary setup help. We’re available to assist five days per week via phone, six days per week via live chat, and seven days per week via email.

Easy Marketing For Your Affiliates, Too

New prospective users often ask me how easy it is for their affiliate to share their link. It’s “stupid simple.” Here’s how it works… When your affiliates sign up with you, they’ll automatically receive an email from you welcoming them to your affiliate program. This email will contain their unique referral link. It will also contain a “one-click” login link to their Affiliate Dashboard. The Affiliate Dashboard is where your affiliate can share their link via email and social media with a single click. For example, when they click the Facebook button, they’ll automatically be forwarded over to Facebook, with a new post pre-populated, and their affiliate link already embedded! They can add a personal note or recommendation if they’d like – or they can simply click “Post” to get the message up on their Wall immediately. This “convenience factor” is huge. Affiliates are able to share their link early and often with their friends and colleagues. It really couldn’t be any easier. The Affiliate Dashboard is also where they can grab marketing materials like banner ads for their website or blog. The banners will already have their affiliate link embedded. So, your affiliate can simply copy the HTML and paste it to their site – or they can have their web developer do this for them.

Use LeadDyno to Track Online Marketing Success

Pay-per-click advertising is becoming increasingly expensive. With LeadDyno, you can use our affiliate program and gain a profitable commission without worrying about creeping costs. As one of the best tracking systems in the market, offering a comprehensive set of features, our software tracking program allows you to manage and observe results of your marketing endeavors. Providing complete information through the affiliate dashboard, LeadDyno’s customizable link tracking platform is easy to understand, responsive and effective. With the one-click sharing option, affiliates can now share their products on various social media platforms and integrate the plug-in on numerous e-commerce stores as well.

Use LeadDyno for Google Adwords Conversion Tracking, Too

I never really knew how Google Adwords was working for me until I began tracking conversions with LeadDyno. While I always used the conversion tracking pixel that Google provides, I always found it to be imperfect. That’s because I want to measure specific $$$ amounts and sales… while Google is only able to tell me if someone made it to a certain page. Like a sign up, or “thank you” page. That’s a good start – but I need more! Specifically, I need to know what somebody bought and/or signed up for… how much they purchased… and how long they stayed with us afterwards. This is easy to do with LeadDyno. All you need to do is create a new marketing campaign tracking link – as use this link as the Target URL within Adwords. Or, if you’re advertising on Facebook, just make sure the link that you provide Facebook with is a campaign tracking link from LeadDyno. Don’t just give Facebook the link to your homepage – give them this link instead. It’s pretty much the same thing as using an affiliate link to track the effectiveness of a specific marketing campaign. Because LeadDyno is already plugged into your website – and most importantly, your E-Commerce provider – you’ll have visibility into the entire sales funnel that was generated as a result of each specific advertising campaign you are tracking. I’ve been doing online marketing for the past decade, and I can tell you this is huge. It allows me to test campaigns quickly and easily. I’m able to let our winners run, and cut our losers short.

Holovect

Holovect – Holographic Vector Display

Kickstarter Page

The Holovect Mk II is a self-contained laser-based volumetric display system that fits on your lab bench or desktop. It is the perfect companion to a 3D printer and a stand-alone educational or promotional device. The Holovect Mk II is the first commercially available, laser-based desktop “holographic” display, capable of drawing 3D objects in air with light.

Holographic Starship! Beam on.
Holographic Starship! Beam on.

Holographic

Holovect images are NOT holograms but instead volumetric vector images projected onto modified air (i.e. projections in space). This distinction is due to the fact that a hologram is a recording of interference patterns on film or glass plates that contains three-dimensional information about an object (greek root “holo” means whole or complete, and “gram” means record). However, since Holovect images contain three dimensional information and are free-floating objects in air, they are most certainly holographic. They are real 3-D projections.

Mirage Technology

So how does it work? The principles are simple. When light travels between two different mediums in most cases you get three different effects to some degree: refraction (bending), reflection, and/or diffusion, depending on the different “refractive index” (RI) of the materials. An example of this are mirages, which occur when a portion of air has a different RI than its surroundings, causing light beams to bend and be reflected in unexpected ways. This can happen because of temperature or pressure differences from one region to the next.

With the holovect technology, we have invented how to control air within a box shaped section of  space to precisely modify the RI within specific regions to refract and reflect a laser beam. This modification raises the “albedo” which is defined as the proportion of the incident light that is reflected by a surface, as well as the refractive properties at the boundary between the modified and unmodified air. Therefore by simultaneously controlling the aim of the laser and the position of a modified air column, a computer can place a volumetric pixel or voxel of light anywhere in 3D space. Then by keeping a laser beam on as it aims from point A to point B a line is drawn which is a 3D vector, and by joining many vectors in a sequence a holographic vector object can be generated. The Holovect Mk II is capable of drawing a complete image 50 times per second within 

a 12cm by 12cm by 12cm cube we call the “drawbox”. Outside of this box things get messy, unpredictable and, in general, not useful.

VECTS 

“Vect” objects are the data-structure developed for the Holovect. Put simply it is a list of 3D coordinates that result in lines drawn in a head-to-tail sequence in space, which are compiled into vect class objects. The files are straightforward and easy to create using a variety of online tools, spreadsheets, or good old pencil and graph paper. Once loaded, vects can be rotated in three axes and moved around within the cubic canvas. These objects can be manipulated using the control knob, preset functions such as spin and move, or used within your own applications.

3-D printing pre-visualizer and Applications

Holovect  Mk II can be used to visualize CAD models in STL format before 3D printing. This can be done in two ways: importing STL files and convert them to vect format, or visualized directly. Depending on the desired visualization, converting the STL will result in a volumetric wireframe projection, whereas direct STL visualization slices the model into layers which is ideal to inspect for potential manufacturing errors and revise inner structure in hollow parts before printing. This volumetric pre-visualization ability increases design and manufacturing efficiency by saving time and printing material before committing to a long printing process.

Other applications include the visualization of 3D data acquired through a 3D scanner, or a computed tomography scan. Commercial applications could also include advertising and branding.

Beyond

As the community grows, our open source software philosophy will allow users to create applications that take advantage of Holovect’s glasses-free, touchable volumetric display. Games, tools and art applications are all in the works and should be available to users by shipping time. Moreover, the hardware will accommodate any advancements in 3D image capture and creation.

Risks and challenges

Our biggest challenge is producing enough units to keep costs low and maintain a large community of content creators. Your contributions will help our efforts and push this nascent technology further than even our imaginations can predict.

We have spent a year redesigning and streamlining the product and production line. We are ready to put considerable amount of units into the hands of developers, early adopters and enthusiasts. Help us make Holovect the standard of holographic volumetric displays.

Dwarf Fortress

Dwarf Fortress

Download Page

Dwarf Fortress (officially called Slaves to Armok: God of Blood Chapter II: Dwarf Fortress) is a part construction and management simulation, part roguelike, indie video game created by Tarn and Zach Adams. Freeware and in development since 2002, its first alpha version was released in 2006 and it received attention for being a two-member project surviving solely on donations. The primary game mode is set in a procedurally generated fantasy world in which the player indirectly controls a group of dwarves, and attempts to construct a successful and wealthy underground fortress. Critics praised its complex, emergent gameplay but had mixed reactions to its difficulty. The game influenced Minecraft and was selected among other games to be featured in the Museum of Modern Art to show the history of video gaming in 2012.

The game has text-based graphics and is open-ended with no main objectives. Before playing, the player has to set in motion a process which generates worlds with continents, oceans and histories documenting civilizations. The main game mode, Dwarf Fortress, consists of selecting a suitable site from the generated-world, establishing a successful colony or fortress, combating threats like goblin invasions, generating wealth and taking care of the dwarves. Each dwarf is modeled down to its individual personality, has likes or dislikes and possesses specific trainable skills in various labors. The second main game mode, Adventurer, is a turn-based, open-ended roguelike mode where the player starts off as an adventurer in the world and is free to explore, complete quests, or even visit old abandoned fortresses. The combat system is anatomically detailed with combat logs describing events like organs getting pierced, fat getting bruised and limbs getting severed.

Prior to Dwarf Fortress, Tarn Adams was working on a project called Slaves to Armok: God of Blood which was a role-playing game. By 2004, Adams decided to shift from the original Armok to Dwarf Fortress after the former became difficult to maintain. Adams calls it his life’s work and said in 2011 that version 1.0 will not be ready for at least another 20 years, and even after that he would continue to work on it. The game has a cult following and an active online community. As there is no way to win, every fortress, no matter how successful, is usually destroyed somehow. This prompts the official community motto: “Losing is Fun!”

Neodymium Magnets

The Differences in N-Ratings for Neodymium Magnets

The Differences in N-Ratings for Neodymium Magnets

Every type of rare earth magnet, whether neodymium, AlNiCo, or something else, has its own alphanumerical system for classifying strength. Each one is unique, and there’s no simple formula for translating a system from one magnet type into the system for another. 

Because the classification systems are so different, it’s important to understand each magnet’s rating system so you can prevent magnet failures and potentially costly or dangerous situations. 

Cracking Neodymium’s N-Ratings

Neodymium magnets are categorized by N-ratings, typically formed by an N, then a number, and then sometimes a couple more letters.

The N stands for neo, an industry simplification of neodymium. The numbers, however, are more complicated. In general, the number indicates the strength of the magnet, measured in Megagauss Oersted (MGOe). If a magnet has a grade of N-42, it has a maximum energy product of 42 MGOe. For every increase of 1, the magnet’s strength increases by about 1%. For example, an N-42 magnet is about 2% stronger than an N-40 magnet.

Once you’ve read the N and the following integers, you need to consider whether there are any letters after the numbers. These letters signal the maximum working temperature (the temperature at which the magnet will begin to lose strength) and the Curie temperature (the temperature at which the magnet will lose all magnetism).

Here’s what you can expect for each letter combination:

LetterMax Working TemperatureCurie Temperature
No other letters≤80°C320°C-330°C
H≤120°C330°C-340°C
SH≤150°C340°C-350°C
UH≤180°C350°C-360°C
EH≤200°C360°C-370°C


When using a magnet with an N-rating that includes letters, proceed with caution. Neodymium magnets that can withstand higher temperatures aren’t pure neodymium. In order to withstand high temperatures, the neodymium needs to mix with other, weaker metals. In general, the more heat resistance a neodymium magnet has, the weaker it will be. If you need a magnet with high heat resistance and high strength, you’ll want a magnet with a high numerical rating as well.

You’ll also need to keep an eye on your budget as these magnets are generally more expensive than those that aren’t designed to withstand high temperatures.  

Putting Your Knowledge to Use

Now that you understand N-Ratings, let’s practice. Say you have a magnet with the following spec: N-30SH. What do you know about it?

The N tells us the magnet is primarily made of neodymium. The 30 tells us its max energy production is 30 MGOe. Finally, the SH means the magnet’s max working temperature is about 150°C, and its Curie temperature is between 340°C and 350°C.

Get Your Hands on Neodymium Magnets

Since you know how neodymium magnets are rated, you should have a pretty good idea of what you need for your facility. Of course, our customer service team is standing by if you need help. When you are ready to buy, Apex Magnets offers a huge selection of neodymium magnets perfectly suited for a variety of applications. If you can’t find what you’re looking for, Apex Magnets offers custom magnets as well.

Self-Driving Cars Are Predicting Driving Personalities

In a recent study by a team of researchers at MIT, self driving cars are being programmed to identify the social personalities of other drivers in an effort to predict their future actions and drive safer on roads.

It’s already been made evident that autonomous vehicles lack social awareness. Drivers around a car are regarded as obstacles rather than human beings, which can hinder the automata’s ability to identify motivations and intentions, potential signifiers to future actions. Because of this, self-driving cars often cause bottlenecks at four-way stops and other intersections, perhaps explaining why the majority of traffic accidents involve them getting rear-ended by impatient drivers.

The research taps into social value orientation, a concept from social psychology that classifies a person from selfish (“egoistic”) to altruistic and cooperative (“prosocial”). The system uses this classification to create real-time driving trajectories for other cars based on a small snippet of their motion. For instance, cars that merge more often are deemed as more competitive than other cars.

When testing the algorithms on tasks involving merging lanes and making unprotected left turns, the behavioral predictions were shown to improve by a factor of 25%. In a left-turn simulation, the automata was able to wait until the approaching car had a more prosocial driver.

Even outside of self-driving cars, the research could help human drivers predict the actions of other drivers around them.

Thanks [Qes] for the tip!

Raspberry Pi Model B Gb

Raspberry Pi 4 Model B 4gb

Raspberry Pi Model B Gb
Raspberry Pi Model B Gb

The moment we’ve all been waiting for has finally arrived, and The Raspberry Pi 4 Model B 4G is now available from DIYElectronics!

The Raspberry Pi Foundation is a brand that just never seems to run out of steam, and after the release of the Raspberry Pi 3 Model B+, the brand dramatically grew in popularity due to the high level of functionality and incredibly low cost – two factors that are amazing for hobbyists like us. However, the recent release of the Raspberry Pi 4 has stepped up this offering even more, offering processing power and functionality that even rivals full-sized entry-level computers! This means that you, as a Pi Maker, have a lot more power to work with, opening up  so many more opportunities for building awesome projects that blow the minds of your friends, family, colleagues, pets and even yourself!

SO HOW IS THE RASPBERRY PI 4 BETTER THAN THE RASPBERRY PI 3 B+?

This is the question in everyone’s minds right now, and we’re quite excited to tell you all about the many small and large improvements that the Pi 4 is ready to bring to the table. So, in terms of upgrades since the Pi 3 B+, the Raspberry Pi 4 Model B 4GB SBC has been improved in every single way, from a more powerful CPU, to more RAM, to more video outputs, and so much more. However, to just mention these upgrades without digging further into the juicy details would do the Pi 4 a great disservice, so let’s explore the fancy, functional and fantastic upgrades a little more – in a convenient and easy to read bullet point format:

Vastly More Powerful CPU – As the main brains behind these little single-board-computers, the Raspberry Pi 4 has been equipped with an extremely powerful Broadcom BCM2711B0 Cortex A-72processor. This is around 4 times more powerful than the Cortex-A53 on the Pi 3 B+, and achieves this power increase by catering to many of the small bottle-necking problems that were simply unavoidable with the previous chip architecture. This means that you can expect much more power from the Pi 4, without any drawbacks, allowing you to really step up your projects in terms of both processing speed, as well as complexity.

Higher Capacity AND Quality Memory – While a lot of people will initially look at the increased RAM and simply think that it’s a larger size, some may not realise that the new type of memory (LPDDR4 SDRAM) also makes a huge difference. Additionally, with a full 4GB of RAM on this model, you can expect not just 4 times the speed, but actually quite a lot more due to the more modern type of RAM that has been integrated. This makes the RAM both larger than previously, as well as faster with a higher frequency, which of course translates to reliable speed and a genuinely amazing benefit that anyone who worked with previous Pi Boards will appreciate.

More Serial Capabilities for Makers – As you will all know, Raspberry Pi Boards are designed for Makers and those interested in learning, and as such always featured convenient UART, I2C and SPI buses to communicate or interface with various low-level modules, sensors and other components. And as Makers, we can’t help but drool over the enhanced serial functionality of the Pi 4, with 4 UART Buses, 4 SPI Buses and 4 I2C Buses – allowing us to really take advantage of the processing power for our strange, wonderful and sometimes whacky Electronics projects.

A MAJOR Step Up for Audio/Video Output – Raspberry Pi has always been a great development platform to work with, offering an incredibly wide range of functionality from basic low-level peripheral projects all the way up to full computer capabilities. However, one area in which Pi boards have always left users wanting more is in the audio/video output. With the Raspberry Pi 4 and the integrated VideoCore VI (6), however, this is a thing of the past, and you can now enjoy Dual 4K30 HDMI Outputs or a Single 4K60 Output via the Micro HDMI ports. Additionally, the PWM functionality of the Pi 4 is no longer shared with the analogue audio output on the 3.5mm AV jack, as it was on previous models, allowing users to take full advantage of all of the different audio/video output options – without having to compromise or sacrifice functionality in other areas.

Now, don’t get us wrong, there are certainly many other awesome upgrades that have been made to the new Pi 4, but we felt that the above were the most exciting few that we as Makers can really take advantage of. As such, let’s take a look at a brief summary of all of the new features and specifications of the Pi 4, and then some of the awesome use cases that you can expect to enjoy when you finally get your hands on one of these beautiful boards.

BuddyTag

BuddyTag

What is Buddy Tag?

Simply put, Buddy Tag is a child safety device that helps parents keep their precious children safe. It has an out-of-range alert to help prevent losing your child; a water safety alert to help prevent accidental drowning; a panic alarm for your child to alert you when in a threatening situation; and a personal ID to help reunite a lost child with their parents. Buddy Tag uses Bluetooth so it doesn’t have monthly fees.How does Buddy Tag work?

We’ve created a video demonstrating the proper setup and usage of Buddy Tag—click here to watch.How does the water safety alert feature work?

When Buddy Tag is submerged in water of about a foot deep or deeper, such as a pool, lake, or ocean, the signal from Buddy Tag becomes weakened. When the Buddy Tag phone app senses the weakened signal, it sounds the out of range alarm.Which phones does the Buddy Tag app work with?

Buddy Tag and its app are compatible with iPhones running iOS 9 and above and Android devices using Android version 4.3 (Jelly Bean) and above.How do I set up my Buddy Tag?

It’s simple! Press the button on Buddy Tag to turn it on. Launch the app on your phone. When your Buddy Tag should show up on the app, just touch it to connect it. There are many other features to make it even more useful for your daily life—watch our video to learn more about them.Can I connect to more than one Buddy Tag?

If you have a Brady Bunch, you can connect to as many Buddy Tags as you need. You can also customize the name of each Buddy Tag in our app, so you will know which tag is on which child.Can other Buddy Tag app users search for my child’s Buddy Tag device?

Once a Buddy Tag is connected to your phone, other Buddy Tag users can’t see your tag. If you want to let another caregiver track your child with the same Buddy Tag, you simply disconnect that tag from your app and let the caregiver connect to it.Can I share Buddy Tag with others?

Certainly. To lend your Buddy Tag to a friend, first disconnect that specific Buddy Tag from your phone app. Now your friend can put the Buddy Tag on their own child and connect to it with the Buddy Tag app on their own phone.What is the range of Buddy Tag?

The range varies depending on your environment. In an open field or a big open indoor space such as a shopping mall, Buddy Tag should work around 80 to 120 feet depending what phone you are using. But if you’re inside a house with many walls, the distance is reduced to about 40 feet.Is Buddy Tag waterproof?

Buddy Tag is now waterproof! Better yet, that allows us to provide a new water safety alert. See a question above for information about that alert.Will the panic button continue to alert me each time it’s activated?

Every time your kid presses the panic button, our app will sound the alarm on your phone and vibrate. (If your phone is muted, it will just vibrate.) At the same time, it will pop up a message on your phone telling you that your child needs you.How long will my Buddy Tag device last?

The battery inside Buddy Tag should last for over a year under normal usage. The battery isn’t replaceable because Buddy Tag is sealed to make it waterproof. When the tag’s battery is depleted, contact us to learn how to exchange it for a new tag ($10).How can I get in touch with you?
