Bathroom fan controller - tests and refinements

 

After building a prototype some more considerations did come up from testing and installation planning.

Trinket M0 - use the watchdog

What if is necessary to use a watchdog for some applications using the Trinket M0 ?

In this article some notes about to do so from the Arduino environment.

Bathroom fan controller - installation

After designing and building the first prototype for the automatic bathroom Fan controller, was time to install it in the bathroom.

Here few notes about what I did.

Bathroom fan controller - the idea

Ok, here a quick and dirty project.

The idea is to build a bathroom fan controller.
One of the bathroom I have has no windows, only a fan to remove the humidity.

I'm tired to have manually to turn it on and off, so time to make this automatic.

Internet Speed Monitor - part 2 - basic SW

 Let see in more details how to put together the basic  internet speed monitor contraption.
This article discuss setting up the Raspberry Pi.

Internet Speed Monitor - part 1 - specifications

Recently my connection with the provider for internet, has some problems.
Running some speed tests from different computers shows really erratic results.

I should have something about 12 Mbit/s downstream and 2 Mbit/s upstream, some tests shows up to 15 Mbit/s-1.5 Mbit/s, others down to 1 Mbit/s-0.25Mbit/s

Not easy to pin point the nature of the problem.

Lights show with Trinket M0

When needed a simple LED show, how to proceed from the idea to building ?

This article is more to discuss strategies and ways to approach a problem rather than describe in detail what is done (also if there is something about that too in it).

Arduino IDE settings for : Trinket M0

The Adafruit Trinket M0 is a small microcontroller from Adafruit, successor of the Adafruit Trinket (3V and 5V) and it can be programmed using Arduino IDE.

Home Automation - fixing Ha-Bridge

Are now years I'm using a program called Ha-Bridge that basically simulate a Philips Hue hub.

The peculiarity of this program is that can be recognized by Alexa and it can control my X10 lights via Heyu. I did set up this system in the 2016, as described in the article of this blog Playing with Alexa and Echo

X10 - AM486 - disable current sensing

At the time of the top usage of X10 there was lot of technical info on the net, today ... not so easy to find them.

I have to modify an old AM486 disabling the current sensing and I didn't find much around, so digging on my old notes here and some searches, I did come up with some info that I hope can be useful to others.
