ESP8266 experiments – making a simple development board

Sunday, October 4th, 2015

The ESP8266 based WiFi modules introduced last year have made making WiFi connected sensor nodes much easier – and much cheaper.

In this article I describe making a small development board for ESP-01 modules, and taking the first steps with it.

Since new users kept asking that same question over, and over, again, I thought I’d write an article answering their question…

When sending products to Mikronauts…

Please remember to identify yourself and the product!

RPi2 + 10.1" TFT Review @ http://Mikronauts.com

(image used for illustration purposes only – the “No Signal” – this is NOT the display I received)

I received a package yesterday with a 10.1″ LCD, HDMI adapter board, and some accessories.

The “To” part of the address was filled out correctly :)

There was no “From” address :(

Even worse, there were no identifying marks on the LCD panel other an an FCC ID which was for another product, and a piece of masking tape on the HDMI adapter board that said 1024×600.

I tried the tracking number, and that did not give me any information on the sender.

If you sent this care package, please identify yourself so I can credit your company in the review!

(knowing the tracking number, or what the accessories were will identify you)

 

Raspberry Pi IoT Experiment #1: LDR & ThingSpeak

Raspberry Pi & IoT – a perfect match!

This article is about logging illumination levels to an IoT service using some inexpensive Light Dependent Resistors.

I tested three LDR’s with different pull down resistors at the same time to see which would give the best results with low and high lighting levels, and posted the Python code for logging to the ThingSpeak IoT service. Plenty of charts for you :)

A Quick Look at Temboo (IoT) Service

Tuesday, April 28th, 2015

I have been checking out IoT service providers to see which ones I might want to use for my Raspberry Pi based DAQ experiments.

Today I am taking a “Quick Look” at Temboo.com to see if it will fit my needs – and if it would fit makers needs.
