Build a frame
- First prototype
- Second prototype (SMD version)
- Emulating MID
- HW1.0-beta1 (third revision)
- HW2.0 (4th revision)
Next step in the OpenBM project is now creating a frame to hold everything in the dash. So, what I did so far, is to get the original mounting frame for the 4:3 bordmonitor (16:9 will also work) and put additional corners in it, to hold the bm device only. Here is an image showing that corners made of alluminium. Please note that I neither have much experience in metal fabrication nor I have right tools for that, therefor the framing might look really ugly. However, it do what it should do, hold the thing together :)
On the backside of the OpenBM device, I placed a plate with wings to both sides.
As result the frame is able to hold the OpenBM device well. The only one thing left is to answer the question of how to build a holding ears or something like this to fit the this outer frame made of black plastic, as shown in the top part of the picture:
Put into Car
Since we would like to have a bordmonitor instead of our MID and Radio device, there is no space in the dash board for the radio. So, there is a need to put the radio into some housing, to make some space available for the bordmonitor display. The best way is to put the radio into the housing of original bordmonitor. However if no such exists, then one need to build one. Here are some pictures showing my self-made housing. I know they are very, very ugly!
I replaced this self-made frame with something more suitable and less uglier. Actually if one measure the distances very well, one can see, that behaind the BMW bordmonitor display housing there is enough space for the original BMW Professional RDS radio. So, I put it inside its original housing and put behind the display.
