Beside some minor soldering issues and a defective connector most of the wall is working. After replacing two defective LED’s and one defective connector a failing row drove me crazy. As you can see in the picture below I forgot to solder one wire. This causes a whole row not working. This was sporadic. Then …
Here some pictures of the three power supplies for the wall. Each is rated at 5V 40A – So theoretically they consume up to 600 Watts. One of the power supply produces noticeable noise. Not sure at the moment if this is because one of the coils is loose or if the supply is defective. …
All power supplies are now installed. I checked all the connections and stride across the wall with a digital multimeter. After correcting some mistakes I turned on one supply after the other. It was a very crumbly feeling I must say, even after investing a lot of time to ensure that all connections were right. …
Last weekend was the time to install the panels at the museum. Since it turns out that the drilled holes are not so smooth as expected I needed to cover all holes with something to make the individual led’s more diffuse. Cut a long story short, I had to cover all the holes with transparent …
The last panel is now soldered and next activity is to install the panels at the museum. This will for sure be another challenge. Also this will be the first time I can see wether one controller for the screen is sufficient. Just in case I ordered a 2nd controller and modified the firmware for …
Beside soldering I am also working on the code. There will be several controller involved. One will control the LED panel. The Firmware for this one is already done. Then there is the liquid simulation and the VR 3D controller. This needs a very strong PC to ensure framerates above 50fps. First I thought that …
The framework for DeinBlau is under construction. In the pictures below you can see that there is already one row of panels installed. The whole framework opens like a door so maintenance will be possible.
After all panels are drilled I took some of them on my summer vacations. I used the early hours in the mornings to start finalizing the panels. To finish one out of the 48 panels I need one hour which means that I have to make the production more effective. The process is like this: …
The display of DeinBlau will have a final size of 3×2 meter. I choose MDF since the material is stiff and not too expensive. A big thank goes to Andy Enderlin who is a woodworker and runs his own company http://www.holzbau-enderlin.de/ He supported DeinBlau by cutting the MDF wood panels into slices. After marking all the panels I …
