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.

Robotics encourages curiosity and teaches students how to think critically—skills that are essential for the future.

2. Planning the Setup

Before starting the Robotics Lab setup in school, it's important to plan carefully. Schools should look at the available space, student needs, and budget. It’s also helpful to talk with teachers, school leaders, and parents to create a shared vision.

3. Design the Space for Flexibility

A robotics lab should be designed to support different kinds of activities. Think about:

Movable tables and chairs for group work.

A safe storage area for tools and kits.

Computers or tablets for programming.

Open areas for testing robots.

A flexible layout will help students feel comfortable working in teams or alone, depending on their project.

4. Choose the Right Tools

Picking the right tools is key for a successful Robotic lab for kids. Students of different ages will need different kits and learning tools. Some basics include:

Beginner robot kits (such as LEGO or mBot).

Microcontrollers like Arduino or Raspberry Pi.

Laptops or tablets for writing code.

Sensors, wires, and motors for building.

Optional tools like 3D printers for design projects.

Try to choose tools that can be reused in many different lessons or projects.

5. Match the Lab to the Curriculum

To make the robotics lab effective, connect it with what students are already learning. This means including robotics in math, science, or computer classes. Schools can also add new lessons focused only on robotics or coding.

This approach makes the lab part of everyday learning, not just a special activity.

6. Work with Experts

Getting help from a professional company can make the setup easier. A good Robotics lab in your school partner will provide:

Help with planning and layout.

Supplies and kits for different age groups.

Training for teachers.

Ongoing support and updates.

They can also help schools keep the lab up to date as technology changes.

7. Train the Teachers

A robotics lab is only as good as the teachers who run it. It’s important to train teachers to use the tools and guide students through projects. Training should include:

How to use robotic kits.

Basics of programming.

Tips on managing student projects.

Ideas for linking robotics with classroom subjects.

Trained teachers will feel confident and excited to bring robotics into their lessons.

8. Keep Students Involved and Excited

Make the lab fun and interactive. You can do this by organizing:

School competitions or robot races.

Exhibitions to show off student projects.

Team-based challenges.

Awards and certificates to celebrate creativity.

When students are excited, they learn faster and build stronger skills.

9. Plan Your Budget Wisely

Setting up a robotics lab can be affordable if planned right. Make a budget that includes:

Tools and equipment.

Furniture and computers.

Training for teachers.

Maintenance and upgrades.

Schools can also look for grants, CSR funds, or partner with STEM education companies for support.

10. Keep Improving

Once the lab is up and running, check how it’s working. Ask teachers and students for feedback. Are the tools helpful? Are students learning better? Use this information to make improvements.

Also, stay updated with new tools or trends in robotics education. Technology keeps evolving, and your lab should too.

Conclusion

Setting up a robotics lab is one of the best ways to prepare students for the future. It teaches real-world skills, encourages innovation, and makes learning exciting. With the right planning, tools, and support, schools can create powerful spaces for students to grow and explore.

From building simple robots to solving complex problems, students will gain the skills they need for tomorrow’s jobs. Robotics education is not just about machines—it’s about building thinkers, creators, and leaders of the future.

◢ #unknownews ◣

Nowe zestawienie interesujących treści z branży IT już na Ciebie czeka.

Naucz się, jak efektywnie przetwarzać dane tekstowe w terminalu Linuksa. Skondensowany kurs dla adminów, programistów i devopsów.

1) Przegląd 22 najlepszych innowacji z targów CES 2025 w Las Vegas https://www.zdnet.com/article/ces-2025-zdnet-best-products-2025-01-09/?utm_source=tldrnewsletter INFO: Jak co roku, na targach CES debiutują nowe technologie, których nie znaliśmy wcześniej. W tym roku było sporo integracji z AI, ale i rozwiązania związane ze smart okularami, monitorowaniem zdrowia i wiele innych. Artykuł omawia 22 subiektywnie najciekawsze z prezentowanych innowacji.

2) Zbackdoorujemy Twoje backdoory! - kolejne sprytne zakupy domen https://labs.watchtowr.com/more-governments-backdoors-in-your-backdoors/ INFO: Pamiętasz grupę badaczy, która kupując wygasłą domenę za kilka dolarów, przejęła rejestr domen MOBI? Chyba im się spodobała ta zabawa, bo wybrali się na kolejne zakupy. Tym razem kupili ponad 40 domen używanych wcześniej w popularnych webshellach. Okazało się, że niektóre backdoory nadal starają się łączyć do wspomnianych domen. Część złośliwego oprogramowania znajdowała się na serwerach rządowych. Ich eksperyment ujawnił około 4000 stale aktywnych backdoorów, które wykorzystują wygaśnięte domeny, które dało się przejąć.

3) Hackowanie interfejsów sprzętowych z Arduino (film, 15m) https://www.youtube.com/watch?v=OlNeXY6SopM INFO: Nie każde urządzenie posiada wygodny panel sterujący, czy możliwość sterowania nim z poziomu aplikacji mobilnej. Czasami mamy do czynienia z interfejsem wymagającym kilkunastu kliknięć w menu w celu aktywacji pewnej funkcji. A gdyby tak to zautomatyzować? Film pokazuje, jak wykorzystać Arduino do sterowania dowolnym urządzeniem. Tutaj autor prezentuje automatyzację chińskiego monitora, ale jest to tylko przykład, który z łatwością możesz przenieść na inny sprzęt. Nie znam się na elektronice, ale ten materiał mnie wciągnął!

4) Zbuduj własną elektroniczną pogodynkę - Raspberry Pi i e-papier https://informatykzakladowy.pl/pogodynka-zrob-to-sam/ INFO: Autor przedstawia projekt budowy samodzielnej stacji pogodowej wykorzystującej płytkę "Pimoroni Badger 2040W" z e-papierowym wyświetlaczem, który ze względu na niski pobór mocy zapewnia długi czas pracy na baterii. W artykule znajdziesz opis zastosowanych rozwiązań zarówno hardwarowych, jak i softwarowych. Nawet jeśli nie planujesz budować swojej własnej stacji pogody, to ten tekst może być dobrą inspiracją do wejścia w świat budowy własnych rozwiązań IoT.

5) Dodajmy autopilota do Volvo... z 1993 roku https://practicapp.com/carbagepilot-part1/ INFO: Autor podjął się wyzwania polegającego na dodaniu funkcji jazdy autonomicznej do zabytkowego Volvo 940 Estate z 1993 roku. Wykorzystał do tego projekt openpilot. W artykule opisano przeprowadzone modyfikacje mechanizmów sterujących, takich jak hydrauliczne wspomaganie kierownicy czy hamulce. Sprytna przeróbka.

6) Jednozadaniowy asystent AI - zrób to sam. Szybki przewodnik (film, 3m) https://www.youtube.com/watch?v=1zBym4evzus INFO: Film pokazuje, w jaki sposób w bardzo krótkim czasie (dosłownie w 3 minuty) zbudować swojego jednozadaniowego asystenta AI, bez programowania i bez zewnętrznych rozwiązań no-code, w pełni wyklikując wszystko w Claude od Anthropica. Asystent wykorzystuje własną bazę wiedzy i bardzo prosty, lakoniczny prompt informujący jedynie, jakie jest jego zadanie.

7) Globalne skanowanie portu TCP 80 - co mówi o internecie? https://redhuntlabs.com/blog/open-port-chronicle-what-port-80-revealed-about-the-internet-project-resonance-wave-12/ INFO: Standardowy port protokołu HTTP (czyli 80) nadal jest powszechnie używany na całym świecie. W ramach badania "Project Resonance" zidentyfikowano ponad 71 milionów hostów, które posiadały ten port otwarty. Jakie usługi tam słuchały, jakiego typu urządzenia to były i co nam to mówi o tym, jak wygląda współczesny internet? Ciekawe statystyki i wnioski.

8) Nie każdy użytkownik posiada iPhone'a - zróżnicowana wydajność urządzeń mobilnych https://calendar.perfplanet.com/2024/not-every-user-owns-an-iphone/ INFO: Podczas testów aplikacji często zakładamy, że wszyscy użytkownicy pracują na najnowszym sprzęcie wysokiej jakości, często dochodząc do pewnego uproszczenia, że użytkownik posiada w miarę nowego iPhone'a. Statystyki pokazują jednak, że użytkownicy z Androidem, często uruchomionym na sprzęcie słabszej jakości, to nadal ogromny odsetek użytkowników. Istnieją kraje, gdzie przeciętny użytkownik posiada telefon 3x słabszy od najnowszego iPhone'a. Jak więc przeprowadzać testy wydajnościowe? Warto zacząć od uświadomienia sobie, jaki jest realny rozrzut użytkowników danej platformy w Twojej grupie docelowej.

9) Tworzenie dynamicznie aktualizującego się Claude Chata bez użycia API https://thoughts.jock.pl/p/dynamic-claude-chat-automation-guide INFO: Korzystasz z funkcji projektów w Claude od Anthropica? Działa ona super, ale każdorazowe uploadowanie nowych, zaktualizowanych danych do kontekstu może być męczące. Niestety, to rozwiązanie nie posiada swojego API, więc automatyzacja procesu wydaje się trudna lub niemożliwa. Claude potrafi jednak dynamicznie czytać dane z Google Drive. Możesz wykorzystać wspomnianą funkcję do aktualizacji bazy wiedzy swojego asystenta. Ten artykuł wyjaśni Ci, jak to zrobić.

Understanding ESP32 Pin Configuration: A Developer's Guide

The ESP32 microcontroller has become a cornerstone of IoT development, thanks to its versatility and powerful features. One of the most crucial aspects of working with ESP32 is understanding its pin configuration and capabilities. Let's dive into the essential aspects of ESP32 pins that every developer should know.

GPIO Pins Overview

The ESP32 boasts up to 34 GPIO (General Purpose Input/Output) pins, but not all are available for use in most development boards. Some key points about ESP32 pins:

GPIO 6-11: Reserved for internal SPI flash connection

GPIO 34-39: Input-only pins with no internal pull-up/pull-down resistors

ADC Capabilities: Two 12-bit SAR ADCs, supporting 18 measurement channels

Touch Sensors: Up to 10 capacitive touch GPIOs

Special Function Pins

Several pins serve dual purposes or have specific functions:

Boot Mode Pins GPIO 0: Bootloader mode when pulled low during reset GPIO 2: Connected to on-board LED in many development boards

UART Pins GPIO 1 (TX) and GPIO 3 (RX): Default UART0 communication Often used for flashing and debugging

SPI Pins VSPI: GPIO 5 (CS), 18 (CLK), 19 (MISO), 23 (MOSI) HSPI: GPIO 14 (CLK), 12 (MISO), 13 (MOSI), 15 (CS)

Best Practices for Pin Usage

Strapping Pins Always check the strapping pin status before using GPIO 0, 2, 4, 5, 12, and 15. These pins may affect boot behavior if incorrectly configured.

Input-Only Pins When designing sensor interfaces, prefer GPIO 34-39 for analog inputs as they're input-only and less susceptible to noise.

Pull-up/Pull-down Configuration

ADC Usage ADC1: Can be used with Wi-Fi/Bluetooth active ADC2: Only available when Wi-Fi/Bluetooth is disabled

Common Pitfalls to Avoid

Don't use GPIO 6-11 in your projects as they're connected to the internal SPI flash.

Avoid using strapping pins for critical functions that can't be changed during boot.

Remember that GPIO 34-39 don't have internal pull-up/pull-down resistors.

Be cautious with voltage levels - ESP32 pins operate at 3.3V.

Conclusion

Understanding ESP32 pinout is fundamental for successful project development. By following these guidelines and best practices, you can avoid common issues and make the most of your ESP32's capabilities. Remember to always consult the official ESP32 technical reference manual for detailed specifications and updates.

UYPP: Ben Ruel's Garage Garden

Back in March, we announced the winners for our Unleash Your Potential Program, in which six participants got to configure their own System76 computer to use for their awesome projects. This first awesome project is the Garage Garden, helmed by awesome project-er, engineer, and mighty green thumb Ben Ruel. We sat down with Ben to see how his project has been growing on the Meerkat.

Can you tell us about the Garage Garden project? What's it all about?

I spent a career with the Coast Guard and came up here—my final tour with the Coast Guard was in Juneau. Being in southeast Alaska, we’re constrained with what they call off-the-road systems, and the only way in or out of town is by boat or by plane. So all of our food comes up here by barge for a small nominal fee, or by aircraft for an incredibly large fee.

When I came up to Juneau with my wife and kids 11 years ago, we noticed that by the time our produce gets up here, it’s lived on a barge a week, two weeks out of Seattle, and you have no shelf life left on them. We started trying to grow food within the first year of getting here, and we came to the conclusion pretty quickly that with 300 days plus of rain every year, outdoor growing wasn’t really a viable option. That’s when we started a hobby farm in a garage growing some stuff in soil under fluorescent lights, as odd as that sounds.

Since then, we’ve progressed into hydroponics, but we’ve done it very manually. We go out every other day and take readings by hand, so I’ve been doing some research about building IOT devices that will talk back and automate some of the readings. My dream would be using it to actually control the concentration of nutrient solutions that we use. The overall goal is we’re going to build the hydroponic monitoring network of IOT devices, and use the Meerkat as a control center for the devices and a repository for all the data. We’ve also been doing some investigating behind the scenes into whether or not it could grow enough legs to become a business.

Is there a specific type of produce that you’re starting with?

We’ve been all over the road. Right now we’ve got lettuce. We’ve always got some kind of green leafy vegetables whether it’s any variety of lettuce that will grow hydro, some bok choy and tatsoi, and we’re growing kale like it’s going out of style. We’ve grown cucumbers to the point where I think I’ve harvested 65 pounds of cucumbers off of 4 plants over the last couple of months, but we’re really constrained by our size.

I live in a relatively small 3-bedroom house, and we’re just using a one-and-a-half car garage as our grow area. Right now I’ve got two tents. As funny as it sounds, cannabis is legal in Alaska and has been forever—my wife and I don’t touch the stuff, but because it’s been legalized, the infrastructure and the supplies that we need are freely available. We’re growing tomatoes in a tent that’s designed for marijuana growth. It works really well. It helps to maintain efficient temperature control; you can maintain temperature and humidity, block out extraneous light if you don’t want it, and cycle the lights on and off.

Depending on whether it’s too hot in the summer we’ll run the lights at night, and in the wintertime we’re looking for extra warmth, we can shift the cycle and run the lights during the day. Our big benefit up here is that, because Juneau’s all on hydroelectric power, electricity is really cheap.

What variables are being monitored?

With hydroponics, there’s a good number of parameters that you’ve got to try and keep track of. You’re basically diluting nutrients in a solution of as pure water as you can get. You want to keep track of things—your pH can’t be too acidic or too alkaline, for example.

The other big parameter is the electrical conductivity, or total dissolved solids. You want to make sure you’ve got the right concentration of nutrients, and that your nutrient solution isn’t salting up. As you’re adjusting pH back and forth, it’ll start demineralizing salt, so tracking that data gives you a good indication for when it’s time to dump the reservoir and start over.

We’re doing it manually now. I go out every couple of days and we take samples, and sit down and log it into a spreadsheet. The Meerkat acts as a control center for programming devices, keeping a repository of the programming for the IOT devices that we’re using (Arduinos with the esp8266 chips) as well as running different database programs as Docker containers, so that they can be spun up and knocked down fast enough as we try and figure out what the best way to move forward is. We’ve got a couple of database servers that I’ve been playing around with, trying to break from traditional SQL and looking at NoSQL type of databases.

I’m not an IT guy by trade. I’m more of an electronics guy, so I’m kind of doing it as a study-by-night type of project.

What has your experience been like with the Meerkat so far?

I’m actually completely blown away by the Meerkat’s performance. It’s astounding what that small form factor and footprint is able to do. I’ve used Linux for a number of years, and basically everybody’s heard of System76. I’ve seen Pop!_OS before and never really played with it all that much, but I’ve actually grown to love it. The feel, the ergonomics, the interface, and even down to the color schemes that come bone-stock right out of the box. They just make more sense to me. I’m looking forward to the COSMIC update after researching that to see how the differences in the workflow will affect things.

What software are you using for this project?

Right now we’re writing in Docker containers and running the Tick Stack from Influx. We’re also running Telegraf, Protograph, Capacitor, playing around with the Time Series Database, I’ve got a container running MongoDB I run with SQLite, and there’s a couple different IDEs I’ve got loaded on there as well for programming Arduinos or esp8266 chip flashing.

How was the setup process for the machine?

It was up and running within 10–15 minutes of pulling it out of the box. I actually took it to work, too. We do a lot of work with government agencies, and I’ve been doing a lot of microwave radio repair. I’ve got a pretty small workbench at our shop here in Juneau, so using the Meerkat to drive all of our test equipment to control the radio while logging data coming out of the radio, it was perfect. It had enough horsepower to remotely control the test equipment. I wasn’t pushing it all that hard, but setting it up and going back and forth between having it at home or at work, it was negligible to get it up and running.

Stay tuned for further updates from Ben Ruel’s Garage Garden and cool projects from our other UYPP winners!
