Lego 42053 Volvo EW160E (Review)
This is my first review of a Lego set. Thank you for watching!
Pros and cons:
– Very good design and good detail
– It includes 2 pumps (one large and one small)
– The large pump works really good

– It’s a little bit wobly when you use the large pump
– It’s difficult to use the switches.

But overal it’s a very nice design and a good piece donor.

How I make my removable stickers for Lego creations 

Hello everyone! I am stickering my Lego bus and I need to make custom stickers. I also made stickers for the ANWB Rally Service Truck and for the Lego Medi. Here is a step-by-step instruction how I make my custom stickers:

Material list

  • normal paper
  • scissors
  • double sided tape
  • Adhesive (one side sticky) window film


  1. Design your stickers on the computer and print on normal paper.
  2. Cut out your design a little bit bigger.
  3. Take the double sided tape and stick your design on one side.
  4. Peel of the other side of the double sided tape and stick it to the non-sticky side of the window film.
  5. Now cut out your design how you want it to be.
  6. Peel of the paper (from the window film) and apply your sticker to the Lego piece.

MA app (Carriage Return problem)

Today I spend the whole morning to make an app for the Lego Medical Assistance, I’m building. The app must send a file to the robot which the robot can read. The file from the robot needs a Carriage Return (Enter) and Line Feed.

CRLF NXT The NXT only reads numbers which are divided by a Carriage Return and Line Feed.


The problem was that Appinventor ( don’t place a Carriage Return. It places only the Line Feed between two lines when you type in ”/n” (for Line Feed).

LF NXTAppinvenor only place Line Feed.


So I tried it a differend way. I make a list called Medicines and tried to save that. And it worked! But the only problem was that it now placed ” around the numbers.

CRLF NXT2It now placed ” around the numbers. But the problem with the Carriage Return is solved.


The NXT doesn’t read the ”. So that was another problem. My mother found a solution on the Internet. You must use a replace element for the text in Appinventor. You fill in the file and what you want to replace. I wanted to replace the ” for nothing so at the ”replacement” I place a textbox with noting. And now I have a file which the NXT can read 😀 .
