ESP8266

Este é o meu protótipo conceitual de um SmartWhatch feito com um mini-microcomputador tipo Arduino: NodeMCU Esp8266. O display é de oled 128x64 e utiliza uma pequena bateria de um celular antigo e a pulseira é de elástico interno de poltronas residenciais e alguns fios são reciclados também. Eu estava pensando em comprar um relogio digital de led, pois ele era diferente do usual e mostrava as suas peças internas, pois era transparente. Foi aí que descobri o Arduíno e montei primeiro um relógio de matriz de leds e inseri no meu robo que que está na parede do meu escritório. Então decidi fazer um relógio de pulso ou Smartwhatch. Pensei em fazer algo diferente do usual. Também queria algo simples, mas criativo. Não foi nada fácil lidar com todos os problemas estéticos, de montagens e os relativos a um software legal. Foi importante a minha experiência como artista plástico, informática, fotografia e escritor de ficção-científica. Depois de muitos dias de trabalho árduo ele já funciona e recebeu alguns melhoramentos. Mas ainda resta implementar algumas funcionalidades. As sua função atual é de um relógio constituído de mostradores digital e analógico em animação através de um display oled. Ele poderá ser modificado ou ampliado mudando-se o seu programa atual de código aberto para poder acessar a internet, Bluetooth, alarme e automatização residencial etc. Tem sido muito interessante este trabalho de criar utilizando o NodeMCU Esp8266 e por isto muitas ideias estão vindo.

PS.: Foi feita uma primeira atualização do relógio: o display oled teve a sua posição modificada 90 graus no sentido anti-horário para assim desobstruir a frente da conexão mini-usb e permitir modificações futuras no programa do relógio. Também foi adicionado um carregador de bateria interno, e um botão interruptor do display oled para economizar energia da bateria. Assim o smartwhatch só mostrará as horas quando este botão interruptor for acionado.

Talvez agora eu só adicione ao relógio módulos que possam ser utilizados para alguma forma de arte. Esta resolução combina mais com a minha formação de artista plástico.

Fetching or posting data over the Internet is one of the main core functions of the IoT device. Doing so over HTTP is better implemented in NodeMCU ESP8366 Arduino libraries, but makes things more difficult for HTTPS requests. In this post, I will talk about the most common approaches used by the community and will show you the method to make Secure HTTPS Requests to URL Using NodeMCU ESP8266. No special certificates or fingerprints are required to manually code the program using this method.

HTTPS Requests to URL Using ESP8266- What are CA certificates?

- HTTPS Requests to URL Using Fingerprints - secure but annoying

- HTTPS Requests to URL Using client.setInsecure() - easy but unsafe

- HTTPS Requests to URL with the IoT framework

- Generating a certificate store

- HTTPS Requests to URL Using ESP8266 Source Code

- Conclusion

HTTPS is a method of requesting HTTP over a TLS (formerly SSL) connection. By doing so, the data sent between and behind your computer and server is encrypted and secure. The good news is that this protocol can be used in conjunction with the ESP8266 WiFiClientSecure class. The bad news is those common methods have some major disadvantages.

First I will discuss the two most common methods, and next, I will describe the generic solutions to their problems.

What are CA certificates?

Before diving into the details I will briefly describe the basic principles of secure HTTPS requests in general terms.

Generally, there is a certificate for each website.

The reboot controller (far upper corner of photograph) is an ESP8266 device which sequences the shutdown, power-off, and restart of the Raspberry Pi used as a Home Assistant controller. It leverages some circuitry built into a home-made UPS mounted on the same rack. The reboot is triggered by an Adafruit IO web page.

Looking a little worse for wear, looks like it's been left outside! I love this little WiFi microcontroller, it's so versatile! This was the core of my breadboard Geiger counter project.

Auf diesem Foto kann man leider die Uhrzeit nicht so gut erkennen.

7-Segment-Anzeige Grove TM1637 mit Microcontroller NodeMCU LoLin V3 ESP8266. Es wird über WiFi eine Verbindung ins Internet aufbebaut und von einem NTP-Server die aktuelle Uhrzeit geholt. Danach zählt der Prozessor selbst weiter und zeigt die Uhrzeit an.

Nachdem es technisch funktioniert hat, habe ich selbst aus Klemmbausteinen ein würfel-förmiges Gehäuse gebaut.

We need them for the new MagicShifter 3000 but they can also be used for fashion ;) I love thos ESP8266 modules :)

I really enjoy working in a professi0onal team now :
