I had to run by a Radio Shack on a few occasions for electronics components right up til their eventual closure.  They had the “electronics components” as a category, but they were largely supplying them from a small stack of cabinets, and not even all of that was populated, alongside maybe two or three types of ‘general starter electronics kit’.  Forget “building a radio”: the local place didn’t even have a full E6 resistors or magnet wire.  And their staff would be better trained to sell RC cars or cell phones (the latter of which was nearly half the store by 2012) than to answer even simple electronics questions.

((Note the lack of transformers even listed on those cabinets; at best they’d have a couple variable-voltage wall warts.))

Their online catalog was better in variety -- I got a lot of copper-plated boards during their going-out-of-business sale -- but it was nowhere near competitive with online sellers even before dropshipping ate the world.  In many cases you’d be looking at three- to five-fold markup over McMaster-Carr or DigiKey prices, even including shipping.

Which... kinda points to the issue with foone’s alternate proposal. A RadioShack trying to sell to hobbyist enthusiasts would have still had to compete with the internet, and hobbyists ended up being pretty fickle about large purchases, too, no matter how much brand loyalty they might have had at a day-to-day basis.

With good reason: those electronics components cabinets often had a 10-fold markup over buying the same from local used electronics shops or 20-fold from online vendors, but if you needed a D-25 or a stack of LEDs in a hurry you’d be willing to pay a couple bucks for the convenience.  And those really weren’t enough to keep the lights on or doors open at the scale -- even small family used electronics shops have to operate at a drastically different format.  Meanwhile, if you wanted to make even a moderately-complicated electronics circuit, you’d be looking at tens if not hundred of dollars in price differences between RadioShack’s local options and online sellers.

((And, separately, the modern education system had absolutely slaughtered any interest in low-level electronics pre-Arduino, and not just as primary or secondary school levels.  I’ve talked with post-grad EEs who hadn’t touched a component smaller than a NAND gate.  The internet has done amazing things for connectivity and community among hardware enthuisiasts, but we’re still a dying breed.))

But RadioShack’s pre-00s business model sold the small stuff like transformers and capacitors so that it could also sell the big stuff: sound systems, full radio kits, so on.  Even back in the 1980s, they were far more .  The point of selling mechanical keyboards, had they made it to today, wouldn’t be to sell a handful of 50-cent cherry switches for $3 each, but that they could sell a 50-buck mechanical keyboard kit for $200.  I think that would have been a more successful approach in retrospect... but it’d also be the sort of thing that would have been ‘successful’ on the scale of a few hundred stores at most, rather than the thousands that RadioShack was operating (and often locked into).

((They did sell Arduino and RaspberryPi-style kits, mostly MAKE magazine or Seeed-variant stuff, just around 2012-2013. But they were very much marketed at Young Children Educational Gifts rather than viable projects.))

Microcenter and some hardware stores have taken that approach, and they do exist -- though it’s still not their core focus so much as a way to drive other sales -- but they’re the sort of business that can only support a location or two per city, rather than the convenient strip-mall front that RadioShack aimed for.

Does anyone remember what happened to Radio Shack?

They started out selling niche electronics supplies. Capacitors and transformers and shit. This was never the most popular thing, but they had an audience, one that they had a real lock on. No one else was doing that, so all the electronics geeks had to go to them, back in the days before online ordering. They branched out into other electronics too, but kept doing the electronic components.

Eventually they realize that they are making more money selling cell phones and remote control cars than they were with those electronic components. After all, everyone needs a cellphone and some electronic toys, but how many people need a multimeter and some resistors?

So they pivoted, and started only selling that stuff. All cellphones, all remote control cars, stop wasting store space on this niche shit.

And then Walmart and Target and Circuit City and Best Buy ate their lunch. Those companies were already running big stores that sold cellphones and remote control cars, and they had more leverage to get lower prices and selling more stuff meant they had more reasons to go in there, and they couldn't compete. Without the niche electronics stuff that had been their core brand, there was no reason to go to their stores. Everything they sold, you could get elsewhere, and almost always for cheaper, and probably you could buy 5 other things you needed while you were there, stuff Radio Shack didn't sell.

And Radio Shack is gone now. They had a small but loyal customer base that they were never going to lose, but they decided to switch to a bigger but more fickle customer base, one that would go somewhere else for convenience or a bargain. Rather than stick with what they were great at (and only they could do), they switched to something they were only okay at... putting them in a bigger pond with a lot of bigger fish who promptly out-competed them.

If Radio Shack had stayed with their core audience, who knows what would have happened? Maybe they wouldn't have made a billion dollars, but maybe they would still be around, still serving that community, still getting by. They may have had a small audience, but they had basically no competition for that audience. But yeah, we only know for sure what would happen if they decided to attempt to go more mainstream: They fail and die. We know for sure because that's what they did.

I don't know why I keep thinking about the story of what happened to Radio Shack. It just keeps feeling relevant for some reason.

Components for a DIY BCI

EEG (Electroencephalography) Hardware:

The most basic BCIs rely on EEG sensors to capture brainwaves.

OpenBCI is a popular, relatively affordable option for DIY BCI projects. While it costs a few hundred dollars, it is one of the most versatile kits available.

NeuroSky MindWave or Muse Headband are other cheaper alternatives, ranging from $100-$200. These are commercially available EEG devices for consumer-grade BCIs.

OpenEEG is another open-source project that allows you to build your own EEG hardware from scratch, though it requires more technical skill.

Electrodes:

You’ll need wet or dry electrodes to attach to your scalp. Wet electrodes give more accurate readings but are messier, while dry electrodes are more convenient.

You can order pre-gelled electrodes online or even repurpose ECG/EMG electrodes.

Amplifier:

The signal from the brain is very weak and needs to be amplified. Most consumer-grade EEG headsets already include built-in amplifiers.

If you're building your own, you’ll need to add an instrumentation amplifier like the INA114 to your circuit.

Microcontroller (optional but recommended):

You can use a microcontroller (e.g., Arduino or Raspberry Pi) to process and transmit the EEG signals.

This allows you to handle signal conditioning (filtering noise, extracting frequency bands like alpha or beta waves) before passing the data to a computer.

Signal Processing Software:

To interpret the brainwave data, you’ll need software to process the EEG signals.

OpenBCI GUI or BrainBay (open-source software for EEG processing) are good choices.

If using a commercial device like the Muse headband, you can use their respective apps or SDKs.

Python libraries like MNE-Python or OpenBCI_Python can be used for more advanced data processing and visualizations.

Steps to Build a Basic DIY BCI

Choose Your EEG Hardware:

If you're starting from scratch, something like OpenBCI Cyton board is a good start. It’s open-source, has good community support, and includes everything from the signal acquisition to the interface.

Set Up Your Electrodes:

Attach electrodes to specific parts of the scalp. The 10-20 system is commonly used in EEG to position electrodes. For basic experiments, placing electrodes on the frontal or occipital lobes is common for reading alpha and beta waves.

Amplify the Signal:

If you're using raw hardware, you need to amplify the EEG signal to make it usable. Most DIY kits or premade EEG headsets have built-in amplifiers. If you're building one from scratch, the INA114 or a similar instrumentation amplifier can be used.

Capture the Data:

Use a microcontroller or a computer interface to collect and transmit the amplified EEG data. For example, with an Arduino or Raspberry Pi, you can read analog signals from the amplifier and stream them to your PC via serial communication.

Process the Data:

Use software like OpenBCI GUI, BrainBay, or MNE-Python to filter and visualize the brainwave data. You’ll want to filter out noise and focus on frequency bands like alpha waves (8–12 Hz) for meditation or relaxation signals.

Analyze and Create Control Mechanisms:

Once you have the processed data, you can start building applications around it. For instance:

Detecting Alpha waves: You can trigger certain actions (e.g., turning on a light or moving a cursor) when you detect increased alpha activity (indicating relaxation).

Training with Neurofeedback: Users can learn to modulate their brain activity by receiving real-time feedback based on their brainwave patterns.

DIY EEG Project Example: Arduino-based EEG

Here’s a simplified example of how you could set up a basic EEG using an Arduino:

Materials:

Arduino Uno

EEG electrodes (you can buy inexpensive ECG electrodes online)

Instrumentation amplifier (e.g., INA114 or an open-source EEG shield for Arduino)

Resistors, capacitors for noise filtering

Cables to connect electrodes to the amplifier

Steps:

Assemble the amplifier circuit:

Build a simple differential amplifier circuit to pick up the small EEG signals from the electrodes.

Use the INA114 instrumentation amplifier to boost the signal.

Connect to Arduino:

The amplified signal can be connected to one of the Arduino’s analog inputs.

Write an Arduino script to read the analog value and send it to the PC via serial communication.

Filter and Process the Signal:

On your PC, use Python (or Processing) to capture the signal data.

Apply digital filters to isolate the EEG frequency bands you’re interested in (e.g., alpha, beta, theta waves).

Visualize or Control:

Create a simple application that shows brainwave activity or controls something based on EEG input (like blinking an LED when alpha waves are detected).

Further Ideas:

Neurofeedback: Train your brain by playing a game where the user must relax (increase alpha waves) to score points.

Control Mechanisms: Use the brainwave data to control devices, such as turning on lights or moving a robotic arm.

Estimated Cost:

EEG Kit: If using pre-made kits like Muse or NeuroSky: $100–$200.

DIY EEG Build: OpenBCI costs around $300–$400 for more advanced setups, while OpenEEG might be built for less, but requires more technical expertise.

Challenges:

Noise Filtering: EEG signals are weak and can easily be corrupted by muscle movements, electrical interference, etc. Filtering noise effectively is key to a successful BCI.

Precision: DIY BCIs are generally not as accurate as commercial-grade devices, so expect some limitations.

Building a homebrew BCI can be fun and educational, with a wide variety of applications for controlling electronics, games, or even providing neurofeedback for meditation

Introduction Model rocketry is an exciting hobby that combines both technology and creativity. Model rocketry enthusiasts are always looking for new and innovative ways to improve their rockets, and one such way is by using an Arduino-based altimeter. An altimeter is a device used to measure altitude or height above sea level. The Arduino-based altimeter is an electronic device that utilizes the power of Arduino microcontrollers to record and store the altitude data of your model rocket's flight. The Arduino-based altimeter can be used for a range of things, such as measuring the maximum altitude of your rocket and ensuring that it deploys its parachute at the correct time. In this article, we’ll provide you with an in-depth guide on how you can build a model rocket altimeter using Arduino. How to Build a Model Rocket Altimeter using Arduino To build an Arduino-based altimeter for your model rocket, you will need the following components: - Arduino Uno R3 board - BMP280 digital pressure sensor - Lipo battery - PCB board - Resistors - Jumper wires - LEDs Once you have all these components, follow these steps to construct your model rocket altimeter: Step 1: Assemble the circuit Using the PCB board, assemble the circuit according to the schematics provided. Start by connecting the BMP280 pressure sensor to the Arduino Uno board. You can do this by connecting the SDA and SCL pins of the sensor to the A4 and A5 pins of the board. Additionally, connect the VIN and GND pins of the sensor to the 5V and GND pins of the board, respectively. Step 2: Add a switch To power the altimeter on and off, add a switch. The switch should be connected to the VIN and GND of the Lipo battery. Step 3: Connect the LEDs Connect the LEDs to the digital pins of the board, ensuring that the resistors are used to limit the current that flows through them. Step 4: Upload the code Once you have assembled the circuit, upload the code to the Arduino Uno board. The code is readily available online, and you can find it on the Arduino IDE or in various online forums. Step 5: Power the altimeter The altimeter should now be powered on, and you can test it by connecting it to the Lipo battery. You can then place the altimeter into your model rocket, and it will record and store the altitude data during the rocket's flight. FAQs About Model Rocket Altimeter Arduino 1. What is the maximum altitude the Arduino-based altimeter can measure? The BMP280 pressure sensor used in this altimeter has a range of 300-1100 hPa, equivalent to an altitude range of approximately 9,000 meters above sea level. However, the maximum altitude that can be measured by the altimeter is dependent on factors such as the quality and accuracy of the sensor, the barometric pressure of the location of the rocket launch, and the sensitivity of the pressure sensor. 2. How can I calibrate my altimeter? To calibrate your altimeter, you will need to use a known elevation location such as a mountain or hilltop. Once you get to this location, insert a battery and turn on the altimeter, then wait for it to stabilize before writing down the altitude data. Repeat this process a few times, and then calculate the average deviation between the readings. You can then adjust the calibration constants in the code to ensure that the altitude measurement is accurate. 3. Can the altimeter record temperature? The BMP280 pressure sensor used in this altimeter can measure temperature in addition to pressure, meaning that the altimeter can record both altitude and temperature data. You can even customize the code to record and store temperature data, in addition to the altitude data. Conclusion An Arduino-based altimeter for model rockets is an innovative way to record and store the altitude data of your rocket's flight. By using this altimeter, you can ensure that your model rocket deploys its parachute at the correct time, and you can also record its maximum altitude.

Basic Understanding of Arduino

Arduino

Hi everyone! In this blog post, I’m going to share with you some basics of Arduino, an amazing open-source platform for building electronics projects. Arduino is one of my favorite tools for prototyping and experimenting with different ideas. Whether you are a beginner or an expert, Arduino has something for you!

Arduino consists of two main parts: a physical programmable circuit board (often called a microcontroller) and a piece of software (or IDE) that runs on your computer. The IDE is used to write and upload computer code to the board. The code tells the board what to do, such as reading inputs from sensors, buttons, or online sources, and turning them into outputs, such as activating motors, LEDs, or publishing something online.

Arduino is very easy to use and learn. You don’t need any prior experience in electronics or programming to get started. Arduino has a huge community of makers, students, hobbyists, artists, programmers, and professionals who share their projects and knowledge online. You can find thousands of tutorials, examples, libraries, and forums to help you with your Arduino journey.

Arduino is also very versatile and flexible. There are many different types of Arduino boards that suit different needs and applications. You can also connect Arduino to various components and modules to extend its functionality and create amazing things. Some examples of what you can do with Arduino are:

- Build a robot that can avoid obstacles or follow a line - Make a smart home device that can control lights, temperature, or security - Create a musical instrument that can play sounds or melodies - Design a wearable device that can sense your heart rate or movement - Develop an IoT project that can communicate with other devices or cloud services

And much more!

What is Arduino?

Today, the world is developing so fast. But the question is, are we?

Today’s stunning technologies are used by us all the day, all the time. Sometimes, we are ourselves fascinated by what we are able to do by just the click of a button. But, what if, we could make all of that, ourselves?

INTRODUCTION

So, the question arises, how can I make fascinating technologies?

The answer is simple: Learning electronics.

And, how to start with it?

The answer is: ARDUINO

All those people who are interested in robotics or hardware engineering might be familiar with Arduino, unless you haven’t made anything from it yet. Arduino is a open-source (open to public) electronic platform based on easy-to-use hardware and software. In other words (for a simpler definition), Arduino refers to an open-source electronics board and the software used to program it. Arduino is a fantastic way for anyone to learn about robotics, hardware engineering and programming. Over the years Arduino has been the brain of thousands of projects, from everyday objects to complex scientific instruments. Arduino boards are able to read inputs — light on a sensor, a finger on a button, or a Twitter message — and turn it into an output — activating a motor, turning on an LED or publishing something online.

Excited to learn it? Here we go!

HISTORY

The Arduino project was started at the Interaction Design Institute Ivrea (IDII) in Ivrea, Italy. The project goal was to create simple, low cost tools for creating digital projects. At that time, the students used a BASIC Stamp microcontroller at a cost of $50, a considerable expense for many students. In 2003 Hernando Barragán created the development platform Wiring as a Master’s thesis project at IDII, under the supervision of Massimo Banzi and Casey Reas. Wiring was important for Arduino since it is based on wiring in both software and programming language. In 2005, Massimo Banzi, with David Mellis, another IDII student, and David Cuartielles, extended Wiring by adding support for the cheaper ATmega8 microcontroller. The new project, forked from Wiring, was called Arduino.

“Hardware becomes a piece of culture that anyone can build upon, like a poem or a song.”

-Massimo Banzi

WHY ARDUINO?

We know what is Arduino, but why should we choose it. There are dozens of other options out there, so why Arduino:

Arduino is an open-source electronic platform. This means that, not only can the public openly use the software and hardware, it can also constantly update and modify the hardware and software, proving Arduino to be diverse collection of boards. As a matter of fact, huge amounts of software libraries have been made by people at various communities to make the Arduino capable of working and behaving much better with more and more electronic components which are coming up.

Apart from that, Arduino is also one of the most cloned microcontroller boards out their. This means that Arduino is unexpectedly cheap. Moreover, Arduino gives a lot of options to choose from while building your project. It has several boards, some small, some large, each having their own features.

Not only that, the Arduino IDE (Integrated Development Environment) is an all-in-one software IDE, which allows us to program in the same language, for almost every Arduino board out there! This helps a lot as we do not have to download a different IDE each time we buy a different Arduino board!

Since Arduino is an open-source electronic platform, A worldwide community of makers — students, hobbyists, artists, programmers, and professionals — has gathered around this open-source platform, their contributions have added up to an incredible amount of accessible knowledge that can be of great help to novices and experts alike. :)

HARDWARE

Arduino is open-source hardware. This means layout and production files for some versions of the hardware are also available. Although hardware and software designs for the arduino boards are freely available under the copyleft license, the developers have requested the name “Arduino” to be exclusive to the official product and not be used for derived works without permission. Most Arduino boards consist of an Atmel 8-bit AVR microcontroller (ATmega8, ATmega168, ATmega328, ATmega1280, or ATmega2560) with varying amounts of flash memory, pins, and features. The most famous and common boards include Arduino UNO, Arduino Mega and Arduino Nano. The boards use single or double-row pins or female headers that facilitate connections for programming and incorporation into other circuits. This allows for the connection of wires with male heads and also the connections for shields. Shields here refer to special arduino boards that can be attached over other boards, so as to increase their functionality. Some arduino boards also include ethernet connections, while some are as small as your thumb! Special arduino boards like the Arduino Lily can also be stitched upon clothes, to make wearable devices.

SOFTWARE

Any hardware is useless without a software. We need someone to explain the boards what we need them to do. For this, we have to speak the board’s language. This language is known as machine code and it exists as a series of 1’s and 0’s inside the memory of the board or the computer. Although machine code might be great for computers, it is extremely difficult for humans to understand. Early computers in the 1940’s and 1950’s had what was known as an Assembler. The job of this assembler was to translate assembly language into machine code. Users could write instructions for the computer known as a program with numbers and things that almost looked like words. While it was still difficult to understand, the language was also unique to each type of computer. It was better than writing a machine code but having to write assembly and learn a new set of instruction for each new computer was quite burdensome. So, people began to create high-level programming languages in the 1950’s, such as COBOL, Lisp and Fortran. These languages did not talk in the native language of the computers, but relied on a compiler to translate the high-level language into something the computer can understand. A compiler is simply a program that does the above mentioned work. When you write a program in Arduino, you write in the combination of C and C++ which is a high-level programming language used to construct instructions for Arduino. Arduino has a special software known as the Arduino IDE (short for, Integrated Development Environment) which provides us an environment to write our code into and upload it to the Arduino board.

That was all about Arduino, and believe me, this was just an introduction. Further, we will be diving deeper into this marvelous world of electronics, made up of wires and pcb’s!

Do not forget to follow and share with your friends and colleagues. Stay tuned for further updates!

Till then, Keep innovating!!
