ghostie arduino chanukiah

for xanuka this year, i made a little electronic chanukiah that i want to share! i know i’m not the only person who can’t do flame-based candles for some reason or another.

this chanukiah is an online simulation that you can run in any web browser, and it is, in my grandiose and objectively correct opinion, better than any other electric chanukiah out there right now.

lots of electric chanukiot do a decent job at emulating the visual appearance of a flame-based chanukiah. the goal with this project was to emulate not only the 🕎visual appearance🕎 of a chanukiah, but also the 🔥ritual experience🔥 of lighting the candles and watching them burn.

some neat features of the ghostie arduino chanukiah:

- candle representation: each candle is represented by a stack of LED lights, and you can make the candles any color you want! if you can express it with a hex code, it’s a valid candle color. there’s also two bonus gradient patterns.

- lighting the candles: you press a button to light the shamash, then you light each candle that you want by moving a slider that lights up its light sensor.

- watching the candles burn: after a candle is lit, the top LED begins to flicker like a flame! and after that, the candle slowly and semi-randomly begins to burn down- the top LED goes dark, and the next one in the stack begins to flicker, and so on, until the light goes out at the bottom of the stack.

- clean up: all the candles will burn out on their own over the course of 30-ish minutes(plus or minus like, 20. i should really optimize the burn pattern a little, lol). after that, you can stop the simulation and reset it for the next night.

it works great on both mobile and desktop, so put it on whatever device you want. a note for mobile users: instructions for use are in the “code” tab, on the top right!

MicroPython mit ESP32: Schaltungen entwerfen und testen mit Wokwi

Im heutigen Beitrag möchte ich dir gerne zeigen, wie du eine Schaltung am für den ESP32 online erstellen und simulieren kannst. Das ist besonders vom Vorteil, wenn du noch nicht soviel Erfahrung oder einfach gerade benötigten Bauteile nicht zur Hand hast. https://youtu.be/THfZxJQZW9Y Für diese Simulation verwende ich Wokwi welches ich dir bereits für den Arduino im Beitrag Arduino & Raspberry Pi – Online Simulator für Schaltungen vorgestellt habe. Hier möchte ich speziell auf die Programmierung mit MicroPython eingehen und dir ein paar Schaltungen und Kniffe zeigen.

Was benötigt man für Wokwi?

Das Onlinetool Wokwi ist kostenfrei und benötigst auch keine Anmeldung. Wenn du jedoch deine Projekte dauerhaft speichern möchtest, dann musst du dich anmelden. Ansonsten benötigst du nur einen Browser wie dem Google Chrome oder Mozilla FireFox (für diesen Beitrag verwende ich den Chrome)

Du kannst dich via Google, GitHub oder mit deiner E-Mail & dem Passwort anmelden / registrieren. Der einfachste Weg ist über das Google-Konto, jedoch möchte die Seite so einige Berechtigungen verlangt, habe ich mich für GitHub und der 2Faktor Authentifizierung entschieden.

Anmeldung / Registrierung an Wokwi via Google, GitHub oder E-Mail Einen Mikrocontroller benötigst du nicht, da alles, was du machst, quasi online geschieht!

"Hello World!" auf dem ESP32 mit MicroPython in Wokwi

Starten wir mit einem kleinen Beispiel und geben den Text "Hello World!" auf der Kommandozeile aus. Dazu kannst du nachfolgenden Link verwenden https://wokwi.com/projects/401020964205534209.

Ausgabe von "Hello World!" in Wokwi mit MicroPython am ESP32 Die Ausgabe erfolgt, wenn du im Bereich "Schaltung" auf die Play-Taste drückst. Zusätzlich läuft oben rechts noch zusätzlich ein Timer, welcher die Zeit der Ausführung anzeigt. Das kleine Programm beendet sich sofort, jedoch läuft der Timer weiter, das ist zum Anfang meist verwirrend. Der Timer bezieht sich quasi auf die Ausführung der Simulation und nicht auf das Programm! # Gibt die Textzeile "Hello World!" # auf der Kommandozeile aus. print("Hello World!")

Aufbau und Simulation einer Schaltung in Wokwi für den ESP32

Du kannst, wenn du nicht aufpasst, deinen ESP32 zerstören, mit Wokwi kannst du deine Schaltung aufbauen, testen, ohne dass du ein Stück Hardware in die Hand nehmen musst. Fangen wir wieder mit einem einfachen Beispiel an und aktivieren / deaktivieren eine LED. https://wokwi.com/projects/401022295974890497

Schaltung - LED mit Vorwiderstand am ESP32 in Wokwi Den Code kennst du bestimmt schon aus dem Beitrag MicroPython mit ESP32: GPIO-Pins steuern – LEDs und Taster. # Modul zum ansteuern der GPIOs am # Mikrocontroller import machine # Modul zum einlegen einer kleinen # Pause im Code from time import sleep # LED mit dem GPIO 32 als Ausgang led = machine.Pin(32, machine.Pin.OUT) # LED aktivieren led.value(1) # einlegen einer Pause von 1 Sekunde sleep(1) # LED deaktivieren led.value(0)

Piezo Buzzer in Wokwi in MicroPython programmieren

Du kannst auch die bisher gezeigten Beispiele in Wokwi nachbauen, unter anderem die Schaltung mit dem Piezo Buzzer, dabei wird der Ton dann vom PC abgespielt. https://wokwi.com/projects/401024173753518081

Piezo Buzzer am ESP32 in einer Simulation in Wokwi # Modul zum ansteuern der GPIOs am # Mikrocontroller import machine # Modul zum einlegen einer kleinen # Pause im Code from time import sleep # Buzzer mit dem GPIO 25 als Ausgang buzzerPin = machine.Pin(25, machine.Pin.OUT) # erzeugen eines PWM Signals buzzer = machine.PWM(buzzerPin) # setzen der Duty auf 512 buzzer.duty(512) # Frequenz des Tones 1000 Hz buzzer.freq(1000) # eine Pause von 0,5 Sekunden sleep(0.5) # PWM Signal & Pin deinitialisieren # damit wird zusätzlich der Ton deaktiviert buzzer.deinit()

Ausblick

Im oben verlinkten YouTube Video zeige ich dir einige Schaltungen und erläutere dir, wie du diese Schaltungen Schritt-für-Schritt aufbaust. Im nächsten Beitrag möchte ich jedoch wieder zurück zum "echten" Mikrocontroller wechseln und die erläutern, wie du einen DHT11 Sensor mit MicroPython auslesen kannst. Read the full article

Coding for Kids, apart from Scratch and Python

Coding and Algorithms is essentially about telling a computer what to do. Like most skills in life, programming involves:

Imagining to solve a big problem

How to break big problems into small step by step procedures and instructions

Express these steps precisely in a particular language following syntax

And learning the patience and mental agility to do the above two

So, what is really important for anyone learning programming is not the syntax of a language, but to learn the underlying algorithmic and logical thinking to solve problems. It is like learning to drive a car, the car doesn’t matter – it could be a Ford or a Toyota, what matters is: are you learning the basics of the use and control of clutch, brake, gear, steering, and acceleration or not?

So, pick your language – Basic Scratch, Advanced Scratch, Python, Java, Roblox, Unity, Minecraft, C#, C++, and many more.

Obviously, children won’t understand this easily. They are at the age of innocence and enthusiasm with a limitless energy to experience new things and do something exciting.  They want to engage visually and build and see what they’re building visually with immediate gratification. They don’t want to write boring extensive classes and interfaces and make packages that are released in one small service pack of a large software after one year. Working with children is far exciting as they will challenge you to show immediate output of what they’re doing in situations and tasks that need not necessarily have an immediate output. Children want to build everything that they see around them. So, we enable them to just do that, and we cleverly embed the most important logical thinking and algorithmic thinking part in the curriculum while they build exciting and engaging stuff.

And not all kids are the same! Some children are more into specific forms of thinking and creativity and while other kids are into different other forms of thinking and creativity in using their intelligence. For example, some kids we teach are into a lot of music and some kids are into a lot of environmental thinking and some are into games and puzzles. So, we induce that respective interest into our teaching and programming exercises accordingly. But, we don’t lose sight of the most important part that we’re here to teach kids – logical thinking, problem-solving and creative-building using programming. 

At UnicMinds, kids can start to learn coding from the below courses apart from Scratch and Python.

Space Programming (15 classes)

Learning to program and build games in Minecraft  (30 classes)

Doodle Programming in JavaScript (15 classes)

JavaScript App development course (30 classes)

Roblox Game Development (30 classes)

JavaScript/HTML/CSS Website Development (30 classes)

Arduino Programming for Kids (using online simulator and also real breadboard and Arduino Uno)

The most important thing is to keep the child engaged in learning programming, the language doesn’t matter so much. The child should love what they’re doing and in that process they will learn the problem-solving skills necessary for overall development.

Yes, most kids might still start with Scratch and Python. But, if you are bored and want to do something exciting, while learning the problem-solving skills, logical thinking and creativity, then kids can take these courses apart from Scratch and Python. For example, it is a good choice for kids to learn Java because it is a widely used programming language in academia and industry. It is used to build a wide range of applications from desktop, mobile and web applications. It is used well to build both backend and frontend applications as it has a popular GUI and also strong support among the developer community. 

Kids should first develop understanding of the basic building blocks to work around in programming such as variables, data-types, loops, logical operators, making a block of logical related statements, composing a program, using arrays, using smaller files and data structures, objects, classes and methods. The trick is to teach them this while engaging them creatively and visually. Not everybody can do that!

We often see a lot of children do courses in major institutes for one year or two years and then they never understand what is a variable. The point is: we are not here to teach syntax or a particular programming language to children. It is like learning a car, which car you learn in doesn’t matter – do you learn the basics of clutch, brake, gear, steering, and acceleration or not matters more than whether you’re learning a Ford or a Toyota! So, focus more on continuity, because that continuity drives the fundamental learning of logical thinking, problem-solving by breaking a big problem into smaller pieces of logical statements.

At UnicMinds, in teaching coding to kids, we focus a lot on providing children the building blocks of programming and logical thinking. If you’re looking for coding courses for your child, then book a free trial with us and understand our curriculum and methodology. Our curriculum is designed by industry experts and smart folks from Ivy league colleges. So, we don’t fool around, we know what we’re doing.

Hope this is useful, thank you.

Smart cities big data civic hackers and the quest for a new utopia, Anthony Townsend

============================

Trade offs of smart cities: efficient but preserve opportunities for spontaneity and sociability. Secure but not surveillance chambers. Open and participatory but provide support structure for those who lack the resources to self organize. Need to be inclusive. "The death and life of great American cities" Jane Jacobs - cities have the capability of providing something for everybody when they are created by everybody.

The unintended consequences of nee technologies dwarf their intended dedign. Motorization promised to save city dwellers from factory smoke but scarred the countryside with sprawl.

Cybernetics. Rio de Janeiro city control room 2012 - remote control city. Norbert Weiner.Jay Forrester - computer models for urban planning.

RAND New York fire department simulation. Oversimplification of model to suit limitation of the computer. Portland 2011 IBM system dynamics for smarter cities. Michael Batty Centre for advanced spatial analysis. Models assumed a closed loop moving from one equilibrium to another and no effect by the external environment.

Patrick Geddes - civic participation

Ebenezer Howard solution for urbsn renewal - start over. Price of city planning is cities built for cars. Tyler Cowen no more big breakthroughs "great stagnation". Hal Varian, rapid transformation.

The history of the internet. TCP/IP favoured by academics won over X.25 backed by telecommunications companies. Cisco, IBM, Siemens planning for smart cities is to cobble together internet of things, analytics, video communications no bottom up everyday people participation. Technology giants designs are 21st century upgrade to 20th century paternalism these design fail to realize the full potential of smart cities. The bureaucrat leaves out time, patience, detail, inter-relating past and future, human purpose, citizens above mechanical requirements.

Dodgeball- crowdsourced online city guides.

Internet of things- not only a system for remote monitoring but also a platform for citizen microcontrol of the physical world. Arduino gives us the tools to structure intelligence into the human scale objects we live in. A social technology that get people talking to each other. Cheap microcontrollers Arduino boards at $25 are networked into clusters.

Foursquare- local, social, mobile software

In 2007 hackers figured how to jailbreak the iPhone. In 2008 Apple co-opted the movement by launching the App store

We can ship laptops to the world's slums but can force anyone to use them. Map Kibera demonstrates how open source tools can empower them to create knowledge relevant to the problems they face. The advent of the digital age means that gatekeepers to information can be bypassed allowing for a new parallel information system to be created by marginalized citizens. Aa fashionable crowdsourcing has become in the developed world it is regressive. Governments may withdraw services as citizen-driven alternatives expand and allow governments to free themselves from the obligation equalize services for the poor.

Apps contests on open city data was a model that could deliver innovation wth nearly zero funding. Problem with apps contests driven by government data is they rely on programmers to define problems instead of citizens or government.

Problem of parochialism in government software procurement. Every city wants to support the development of a local technology industry. Reinvent the wheel and dress it up as an innovation program. Variations of the same service, subpar apps and different one for each town.

"Connected cities" Haselmayer

Contrast to situated software

Rebound consumption or Jevons paradox: improve roads or have driverless cars, same congestion as people buy more cars. Better power efficiency, costs lower, people buy new appliances

Effizientes Prototyping: Arduino-Simulation mit TinkerCAD

In diesem Beitrag möchte ich dir TinkerCAD von Autodesk vorstellen und zeigen, wie du damit dein Prototyping am Arduino effizienter machen kannst. Mit dem bereits veröffentlichten Beitrag Arduino & Raspberry Pi – Online Simulator für Schaltungen wo ich dir Wokwi vorgestellt habe, habe ich dir bereits eine gute Lösung gezeigt, hier soll es nun um eine Alternative zu diesem gehen.

Warum sollte man eine Schaltung simulieren?

Der Vorteil einer Simulation am Computer ist, dass du alle Bauteile vorhanden hast und dir nichts kaputtgehen kann, wenn du mal etwas falsch verdrahtest. Des Weiteren bist du mit einem Tool wie TinkerCAD (oder ähnlichen) viel schneller und effizienter. Zusätzlich kannst du hier auch mal etwas ausprobieren, ohne gleich tief in die Tasche greifen zu müssen und so deine Schaltung im vorn hineinplanen.

Anmelden an TinkerCAD

Damit du TinkerCAD verwenden kannst, musst du dir zunächst ein Konto anlegen. Dieses kannst du ein bestehendes Google oder Apple Konto machen. Oder du erstellst dir mit deiner E-Mail-Adresse ein eigenes Konto.

Wenn du angemeldet bist, dann kannst du über die Schaltfläche "Erstellen" (1) aus dem Untermenü den Eintrag "Schaltkreis" (2) wählen.

Erstellen einer einfachen Arduino-Simulation mit TinkerCAD

Im ersten Schritt wählen wir einen Mikrocontroller aus, hier kannst du zwischen einem BBC micro:bit, Arduino UNO R3 und ATtiny wählen.

Dieser Beitrag soll sich zunächst um die Simulation von Schaltkreisen am Arduino handeln, daher wähle ich diesen aus und platziere diesen per Drag'n Drop auf die Arbeitsfläche. Der einfachste Schaltkreis am Arduino UNO ist wie immer eine blinkende Leuchtdiode. Eigentlich benötigt diese keine Simulation, denn, wenn du eine LED falsch in den Schaltkreis einbaust, dann leuchtet diese einfach nur nicht. Jedoch benötigst du dafür lediglich wenige Komponenten und Code, und daher ist es der ideale Einstieg. Die interne LED ist am digitalen Pin D13 angeschlossen und an diesen verbinden wir nun eine LED mit einem 220 Ohm Vorwiderstand.

Der Beispielcode, welcher bereits existiert macht, hier genau das, was wir benötigen und daher ist unser kleines Programm und die damit verbundene Simulation schon fertig.

Programmieren

Den Code erstellen wir ähnlich wie in MakeCode oder Scratch mit vorgefertigten Blöcken. Hier findest du zu jeder verfügbaren Komponente einen Codeblock und somit kannst du sehr einfach und schnell dein Programm erstellen. Nachfolgend ein kleiner Codeblock zum Drehen eines Servomotors von 1° bis 180° und zurück. (siehe obiges YouTube-Video)

Fazit zur Arduino-Simulation mit TinkerCAD

Als Fazit zu TinkerCAD als Tool zur Arduino-Simulation ziehe, ich, dass dieses für kleine Projekte gut brauchbar ist. Was ich besonders cool finde ist, dass dieses bereits mit einer Vielzahl von Komponenten bestückt ist und somit schon einige Projekte simuliert werden können. Jedoch fehlt hier eine Möglichkeit diesen Code, als INO-Datei für die Arduino IDE zu exportieren, was ich leider als deutlichen Minuspunkt werten muss. Read the full article

-WIP-Technical Specification

• 1. Document Using sensors and projectors in combination with sound to create an interactive reality "ASMR" device.

The computational part includes: 1. Programming the sensor and devices connected to it, setting up the corresponding actions. 2. Programming the background image to be dropped by the projector, using the p5.js library.

Using Java Script language and P5.js library for setting up the visual image part. And use C++ language with Arduino kits to program the sensor to control the devices.

I will use Physical Computing techniques and use the circuits to connect the sensor and devices. Also, if it is possible, I will let the sensor make differences on the projector image as well. That will depend on how much I could take control of the sensor and the relevant coding problem.

I will use some of the knowledges from Physical Computing module and follow the tutorials of class, but also will look for the tutorials on YouTube. I have already found some of the tutorials for designing the background image projecting.

The specific data set need to wait after I decided which kind of the sensor I will use in this project. The choice of sensitivity and the type of sensor affects the exact method of operation in the interaction as well as the programming direction.

• 2. Code snippet

Below is the code fragment for the projecting part I have already done. On this basis, the animation and changes will be further enhanced to create a more suitable "hypnotic" effect. At the moment it is a loop animation with color changing, simulating the scene of hypnosis.

The code can be run in the P5.js online editor.
