Bathroom fan controller - tests and refinements

 

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

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.

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.

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).

A family size UV sterilizer - the electronic

At this point what is needed is a timer to control the lights and also a switch used for safety and to start the operations.

In this article I will discuss  about how to design a circuit capable to "read" the rotary dial and relative code.
