LEGO Brick Dimensions and Measurements

Posted by on Apr 21, 2019 in Uncategorized | 6 comments

The LEGO bricks are precisely designed to fit perfectly together. There is a 0.2mm gap between bricks next to each other. The gap between two bricks stacked on top of each depends on how careful to pressed them down. Of course there are several websites that show you the exact measurements, but some of them were a bit confusing or even broken.

LEGO 2×4 Brick (3001)

I enjoy working in 3D so I used Fusion 360 to create this technical drawing of the LEGO Brick. You can download the model over at GrabCAD and the PDF file from here.


LEGO 2×4 Plate (3020)

This plate is 1/3 of the height of a normal brick. You can download the model at GrabCAD and the the PDF file from here.


LEGO 1×4 Technic Brick (3701)

The technic bricks have a hole in the side for pin connectors or axles to go through. I had to cut open a brick to get the exact design of the inside tubes right. The model is available at GrabCAD and the PDF file from here.

Problem with flickering pixels on Philips BDM4350UC/75

Posted by on Aug 19, 2016 in Documentation, Uncategorized | 3 comments

I enjoyed the large 43″ Philips BDM4350UC/75 for two weeks now and the screen size is just wonderful. It is just like to large monitors in one. I discovered to problems, one just a bit annoying and another rather big issue.

The smaller issue is related to the power saving function. When I ran the all black screen saver on my Mac Pro, the screen seems to go into its own sleep mode of which it does barely ever awake. Sometimes I could bring up the OSD and this would bring the screen back to life. I got used to switching the screen off with its own power switch and turn it back on in the morning. This might not be such a bad idea anyway.

The bigger issue is the display of certain colors, or the lack there of. When I want to show light grays, such as RGB 193,187,194 I get vertical lines of flickering pixels. I took a photo of the screen to demonstrate the effect. We visited the dealer and tried the same color/image on their showcase model with the same result. There seems to be an issue with this Philips display. Be aware!
