ESP8266 Wearable Access Point

I wanted to create a couple of wearable devices using the ESP8266 for a SEAWare MeetUp. The first thing I needed was a wearable Wi-Fi access point. My first wearable project would use the access point to coordinate communication between my iPhone and other ESP8266 devices.

I decided to use a lanyard to hold both the battery and a very visible ESP8266 circuit board. I included an 8×8 matrix LED from Adafruit that use I2C communication (needed for he ESP-1). Features included:

  • ESP-1 access point
  • 3.3 volt lithium ion battery
  • 8×8 LED matrix
  • 2-position DIP as a power switch
  • iPhone to select different scrolling text messages

My next couple of posts will describe the wearable name tag with its OLED display, gyro-accelomter (posture sensor) and IR LED switches.

ESP8266 ESP-1 Internet of Things

I’ve recently started working with the ESP8266 model ESP-1 Wi-Fi web server, web client and access point. It is an incredibly powerful microprocessor with an equally powerful Wi-Fi radio. Its 32 bit, 80 MHz processor has lots of memory (compared to my ATMega328) and at around $2 US, its hard to beat.

You can use several different development environments but the ESP8266 community has┬áported it to the Arduino IDE. I’ll post a few of my most recent prototypes in the next couple of days.
