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 ported it to the Arduino IDE. I’ll post a few of my most recent prototypes in the next couple of days.

DIY – Home Automation and Monitoring

I’ve spent the last couple of years learning digital design with the Arduino platform. The open source hardware and software communities have been immensely helpful and I could’nt have made much progress without their help.

I decided to use home automation and motion surviellance as the central theme for my self taught, hardware design education program. Today, my home has many sensors collecting data in each room and communicating status to my iPhone via Bluetooth devices. I’ve used an nRF24L01 2.4 GHz radio in a mesh network to coordinate each device.

I will document version 1.0 of my home automation system on “parttimemaker”.
