LEGO GBC Module: Pneumatic Tower

LegoGBC presents us his latest GBC module, a Pneumatic Tower which was inspirated by Akiyuki, but with a 90 degrees angle.

“It uses a single switch and 2 cylinders. Because the air will always go to the cylinder which job is easier, the movment sequence works perfectly with one switch.
2 PF M motors are used to compress and change the switch’s position, (2 because one PF M was too slow and I don’t have an XL motor)

It was very hard to build the body of the crane as the cylinders try to “escape” from turning the gears.”

Lego GBC ROD now with instructions!

Do you remember the Lego GBC ROD module?

It was made by the Spanish Lego GBCer Parda (Who also made this fantastic article with tips for GBCs). A while ago he asked me to make the lxf file for it, so users could download it and use Lego Digital Designer to build it.

Well, here it is the LDD File! Download it here!

Some extra data about this GBC. Here you can see how it started:

It was the very first Lego GBC module I did!


Well, it is not exactly the same but similar :). And it was done without any kind of instructions :D.

New Lego GBCs

Here at YB we are always glad to present new Lego GBCs. ANd today is one of that days. The youtuber 05yattaran has posted some new and elegant Lego GBcs in his youtube page:

Although this module may not seem to be technically complicated, when we aproach to the rear part of it we can see the gearbox which changes the speed.

GBCers used to used a Lego Speed Regulator for this function but it is an old piece and not easy to find, so this solution is brilliant!

This second module is not as complicated as the previous one, but I like it as well. The colours used and the style of the Lego Pieces he has used has impressed me.

Thank you for your Lego GBCs!

The Witch Lego GBC

Pg5200, a known man here at YIHARUABLOG, has published a new GBC recently.

It may not seem so mew. It is just a wheel. But the Lego Witch and the design are very original. This is another example of how to make an original Lego GBC.

Philip Verbeek’s Lego GBC 8

First of all and sorry for this:

#Ihatethenewyoutube which doesnt allow me to do anything with my Yiharua account. I must connect it to Google+, which I have never planned to have. After that it obligues me to do a new channel in order to use my account. WTF!!!??? I cannot use the old one anymore!

Why do I say this? I wasn’t able to comment in Philip’s lego video for this reason. And I wanted to denounce Youtube.

Well, after all this, here you can see the last video of one of the greatest Lego GBC contributors of this blog: Philip Verbeek:

I hope you liked it!

Abd Philip, my comment in youtube (In the shit it has became…) would be something like this: Those wires are magnificient. Very clever modules as always. Congrats ;).


The latest genius by Akiyuki

Akiyuki, as most of you know, is the most succesfull Lego GBC builder in the world. His latest creation is a ball activated module. A really clever idea, which is typical on him. I am pretty sure you will enjoy the video ;). 

Lego GBC Wheel Module

We have a new Lego GBCer! And it has started to post his GBCs in youtube. I bring you an example of his creations: A Lego GBC Wheel

I hope you liked it! I highly reccomend its Youtube channel!

Lego GBC Jumper Module

An image is better than a thousand words:

Lego GBC Jumper Module

Today I present you my Lego GBC Jumper Module. Basically it consists of a bar connected to a shock absorver. When pressure is left, all the force is released and the ball is fired.
This is so far the most complex GBC I have ever posted (There are many “big fails” that I will never publish… But much more complex). Besides this in that small space we can find two links going up and down and a ball remover.

Apparently it has no errors. The only small problem happens when the ball is elevated. Sometimes it doesn¬īt fall to the launcher.

I am very proud of this module. It has been many months in my mind, undergoing continuous changes, until I have solved them. In part, the previous module (Which you can see here) was made to cheer me up, because this was all a puzzle.

The original idea for the kick launcher comes from Philip Verbeek (The European Akiyuki… He has some impressive GBCs. Ought to see them). The music of the video is owned by Alasdair Fraser. I hope you enjoy it.
