Chamberlain Garage Monitor repair

As usual I love to go exploring in flea market/antique malls.
Last time I did find a new Chamberlain Garage Control. 
Of course the unit ended up in the flea market because not working.

Pokit

Long long time without writing something, I guess I'm really busy :)
However something happens in my world.

A couple of years ago I did find an interesting Kickstarter project and I decided to participate, Pokit.

It took forever to receive finally the product but in the end, finally arrived !
Few notes about it.

Simple timer

Sometime is not necessary to go sophisticated for some applications but at the same time, "easy is not always easy".

Here an interesting problem.
An old puppet contained a timer to turn on a LED for few minutes.
The goal is to replace the broken circuit.

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).
