ESP8266 + IR Receiver + IR Transmitter

When I was using raspberry pi, I bought a IR transceiver module for Arduino. and used it for several years. IR transceiver

And this year, I am interested in ESP8266, so I bought another IR receiver, IR transmitter.

Installed.

Install esp8266 and voltage converter on breadboard.

Install IR receiver and IR transmitter in front of tv

My Raspberry Pi 1

• Bought : ₩58,000 2013/04/24

  • with : PiFace, BOARD, I/O EXPANSION, RASPBERRY-PI (₩48,570)

• At First : install raspbian. tested relay, and tested led on PiFace

• As a IR Remote controller : telegram-bot-try2, 2019 May IoT project

• As a Thermal sensor : finally just read DHT11 temperature/humidity and send it to the server.

  bash

  #!/bin/bash
  
  export API_URL=https://public-api.dgkim.net
  export API_KEY=----
  
  export DHT11=/home/pi/git/rpi_sensor/src/test_dht11
  
  export HUMI_TEMP=$($DHT11 | tail -1)
  
  HUMI=$(echo $HUMI_TEMP | tr "," "\n" | head -1)
  TEMP=$(echo $HUMI_TEMP | tr "," "\n" | tail -1)
  
  TIMESTAMP=$(date +"%Y-%m-%dT%H:%M:%S%z")
  
  echo "HUMI $HUMI"
  echo "TEMP $TEMP"
  
  
  curl -X POST "$API_URL/v1/temperatures/" \
  -H 'Content-Type: application/json' \
  -H "X-API-KEY: $API_KEY" \
  -d"
  {
    \"temperature\": $TEMP
  }

• Today : Turn it off.. and remove SD Card from it. Please Rest in Peace my raspberry pi.

Story

I wanted to implement automatic LED light, when I approach kitchen.

Prepare

• ESP8266 compatible board. (I use ESP01 board this time)
• WS2812B LED Strip (5v addressable LED)
• HC-SR501 PIR Sensor (body detection sensor)

Wiring

• WS2812B

  • vcc : to USB 5v positive pin
  • gnd : to USB ground pin
  • data : to GPIO1 of ESP01

• HC-SR501

  • vcc : to USB 5v positive or 3.3v
  • gnd : to USB ground pin
  • data : to GPIO0 of ESP01

Result

Bought Pico PC

I bought Pico PC via indiegogo fundraising several months ago.Oct 2022 - Bought Pico PC

Long-waited Pico PC is just arrived today

First impression

Booting the box.

Next. the boring win10 boot sequence starts.. (before installing ubuntu, let’s see what is win10, what it looks like)

Showing User’s application in Show all applications

On ubuntu, when you press Super key twice or press Super+A, you see applications installed on host. But, not all applications are installed via dpkg or snap. for example, Postman and Bitwarden doesn’t provide installers instead they provides something like App Image.

I place such programs in ~/Applications. and I want to run this kind of program conviniently using Super key like Spotlight search in Mac.
