Interesting, the experiment they send us at my daughter’s school. It is a simple experiment to do with our children and introduce them to the wonderful world of science, although with this we may be conditioning them.

Recovering an old Linux computer
I continue with the repairs of PC and devices although this cannot be considered in itself a repair. But it is something that they ask me more and more. Install some operating system that makes them work on computers with old hardware.
And although I tell you a little about the decisions I have made in this specific case, it can be extended much more. I will try to update and leave what I have done every time the case is presented.
Follow the series of articles on computer repair. Common things that anyone can fix in our house like when the computer turns on but you don’t see anything on the screen.
DIY projects to recycle a CD/DVD reader
Today it is common to have old CD or DVD players at home that we no longer use and are a great source of hardware for our DIY projects.
I will disassemble a CD player to see the pieces that we can take advantage of and leave a list of very interesting (Instructable) projects that can be done with each of the pieces. The links are projects in English, but little by little I will try to reproduce them and leave you all the documentation in Spanish.
This model is quite old. I think it still works, but since I have 6 or 7 more it has been sacrificed for the article 🙂
How to install APK on Android
I take advantage of the round to fix mobiles that I am doing to explain and document many actions that friends and family usually ask me. In this case I explain how to install APK applications on Android.
I go straight to the point, if you want to know what an APK is and when you may need to install one, go to the end of the article.
In my case I will reinstall Play Store that works badly on a mobile that we will use without SIM for my father-in-law to play. I can not open it, or even factory reset and I find it much faster to install the application directly than to see what happens to the smartphone or flash it.
Build Rosetta and Philae with your children
If you want to spend a weekend teaching your child more about space, astronomy, science and aeronautics, I let you a collection of resources that ESA (European Space Agency) has hung for teachers and children.
You can take advantage of the fact that the subject is not very old to introduce to your child. That an object has been sent from the earth to a comet at 500 million km and that it travels at 60,000 km / h because it has to impress you. Well, this is what the Rosetta Mission has done with the Philae probe.
Wooden outdoor games
I met twice this year with classic wooden outdoor games and activities for children during events at village parties. They are games made of wood, very basic and simple things that they love. Some to play alone and others to do it in pairs or as a team.
I want to ride some for summer so I can play with my daughters and my nephews, taking advantage of wood that we have that are being spoiled by having outdoors. This article is a compilation of those that I have been able to take pictures and those that I remember. There was one day that there were so many people that I couldn’t take pictures. In all games we can make many variations of both rules and variations in construction. The notes are as a reminder.
SIM card sizes. How to cut a SIM card
This is a modification I made a long time ago, when I bought my old Nexus 4 and I needed to cut the SIM card. It may seem outdated because most new cards come precut but the truth is that many of us still have old cards and we can save a few dollars and with this hack.
And we will also use the article to talk and explain the sizes of the SIM cards.
I receive my Nexus 4 from Google. I’m going to try it and I realize that it uses micro SIM 🙁
The logical solution is to go for a duplicate SIM card, but they charge $5 (yes, it was free before) So you have to find a homemade solution and this happens to cut the card at home to convert the mini SIM into Micro SIM.
