Internet of Things (IOT)

Getting started with IoT on AWS, Arduino and ESP8266

After the recent outage on this server where the site was down for many hours (and days), I’ve decided to go back and post important tutorials on my WordPress site so that knowledge is accessible anytime to anyone and should not be dependent on my server being down.

As such, I’ve begun writing the primer and you can read it here:

Thanks for sticking around 🙂

Arietta – ARM9 Mini Module

Came across this awesome new ARM9 Mini Module running at 400MHz:

Comes with Awesome set of features:

Main features

  • CPU Atmel AT91SAM9G25 SoC (ARM9 @ 400Mhz)
  • DDR2 Ram 128 or 256 MByte
  • Power supply: 5VDC via microUSB or 3.3VDC using the PCB pads
  • Line levels: TTL 3.3V (NOT 5V tolerant)
  • Operative temperature range:
    • ARIETTA-G25 (128MByte RAM): -20 +70 °C
    • ARIETTA-G25-256 (256MByte RAM): -0 +70 °C
  • Size: 53x25mm
  • PCB layers: 8
  • RoHS and REACH compliant. Low EMI
  • Availability: > 5 years
  • Designed and Made in Italy

I’ve reproduced this from their main site here:

Things getting exciting!!!

MicroPython – Python for Microcontrollers

I was greeted by an awesome message from my pal Aman when I logged into Facebook:

and that led me to this page:

Looks very cute, has met all of the stretched goals that will now allow it come with support for WiFi, Ethernet and low power wireless support through Libraries. The form factor is very cute and this looks as a promising platform to introduce students/makers to the fascinating world of Embedded and Python.



The price is decent and competes with Raspberry Pi, Arduino and other dev boards. I particularly love the form factor which makes it suitable for IoT projects. Hoping for it to arrive in India soon.

Thanks Aman for the pointer 🙂

Eclipse release IoT stack

The IoT (Internet of Things :P) space is getting pretty interesting. Eclipse (one of my fav IDEs) has now released a powerful IoT stack for Java developers to build awesome IoT applications.

This is getting interesting 🙂 I need to try out a demo… Hey, they even have a live demo page setup here that’s playing with the Raspberry Pi:

Happy IoTing 😛

GDG Dev Fest — Using Chrome Serial API to talk with Arduino

I happened to present a talk at the Google Dev Fest Hyderabad that took place this Saturday, 5th October, 2013.

I’ve uploaded the slide decks used and also the code used in the demo. Please find them below. If you need any help on implementing these, please reach out to me.
