SIM card sizes. How to cut a SIM card

SIM card Sizes. SIM, mini SIM, micro SIM and nano SIM — Wikimedia

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 It may seem outdated because most new cards come precut but the truth is that many of us still have old cards and we can save a few dollars and with this hack.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.

Aireless Tires wheels

Non-pneumatic heavy machinery Tweel wheels

This is one of those topics that I like even if it is not a DIY. It is not topical, since it has been talking about this type of airless wheels or non-pneumatic wheels for a few years, I think since 2002 approximately.

If you have never seen a wheel of this style it will impact you especially when you watch some videos and discover what they are capable of withstanding. I leave one for you to enter into matter. It’s from Michelin Tweel wheels.

How to start a beehive into a glass jar

We have already seen how to make a DIY beehive and now I leave a modification or extension that we can make to a hive as a curiosity. The idea is to get a honeycomb in a jar or glass bell.

It is a very interesting science activity to show children. Although I have seen this product for sale, here I present it in a didactic way as a way to teach children and adults the ins and outs of hives.

How to make

I collect this information because the original page where it was published and that it linked no longer has the article.

The technique is very simple although we need to have a hive, of course.

Place a bell, with strips of the hive so that the bees begin their work.

How to make gel ice packs

You do sports? No? Well, surely you know someone who does and that comes full of bruises, overloads, etc. and that they say the sport is good 😉

The other day after a long workout, I came home with knee pain. At home I had a 3M cold and hot gel pack but why buy a bag if we can make it?

How to make homemade baby wipes

If you are a father, you will use wet baby wipes and it is one of those things that from the tests you know that you will continue to use them forever.

I bring a tutorial on how to make wet wipes, which we can use either with our baby or for domestic use. A great and really homemade DIY.

The wipes we have obtained are very cheap, although it will be difficult to replace the commercial ones with these. Yes, it is true that if you have run out and the stores are closed or you have gone on a trip or your baby has some type of intolerance to chemicals that carry the commercial wipes, then this tutorial may come in handy.

PCL or polycaprolactone (Plastimake, InstaMorph, Friendly Plastic)

If this is the first time you hear this name, you are in luck because today you will be surprised. The PCL is a thermoplastic plastic that we can mold with our hands when heated around 60 ° C and that hardens in the cold and we can repeat the process again and again, hundreds of times.

Plastimake, instamorph and friendly plastic

When it cools it becomes hard and tough, it does not conduct electricity or heat, it is not toxic and it is biodegradable. It seems the perfect solution for our inventions does not?

It reminds me of Sugru, but being able to reuse it and it seems to be more difficult to manipulate. Although of course being able to reuse it again and again is a very important point.

Look how the magic happens …

DIY beehive

Oscar Perone, sent us this tutorial about how to built homemade beehives some years ago, to publish it in the spanish web. I reproduce it literally. Enjoy it!

The beehive I propose

It is possible to do beekeeping without knowing anything about it, manufacturing our own material with waste wood and populating our cheap hives with swarms that we will capture for free. The result will be an automatic beehive that will only open to harvest.
