Server chronicles - upgrade RAM and HD to the System76

It is time to upgrade the System76 server.
The original configuration had 4 GB of RAM and 2 HD SATA in RAID 1 of 2 TB,

with the upgrade I'll bring the RAM up to 32 GB (the maximum  RAM this 7 years old mother board can handle) and I'll install 2 4 TB SATA HD in RAID 1 or 2.

Server chronicles - HA temporary server (UPDATED)

Among many other services, my server hosts some HA services to control my X10 lights and some operations.
Since my glorious server need to be rebuilt and as usual I don't have time, I needed to find a quick solution for my X10 server.
I decided to use a spare Raspberry I have around and create a temporary HA server, until the main one will be restored.

Server chronicles - planning - UPDATE !

Well, it was matter of time.  

An hard drive in the server died during the latest thunderstorm.
It is time to do some maintenance to the system, very probably rebuild it from scratch, a good time to reinstall only what is really needed and  a full upgrade to the latest version of Linux.
After 7 years of continue service 24/7 I would say it is time 😁

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.

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.
