Here is the conundrum. I have been mustering broken URSA MINIs with a view to eventually combining enough bits to make up a complete camera. One is an URSA MINI 4.6K which presented with a substantially damaged upper case with the top broken out.
The described history was that it had functioned after its accident but had since succumbed. In the course of its journey, something must have jolted into place. It was fully working when I decided to power it up to see what was left of it that worked. I was mainly after the SSD recorder it was wearing.
I was minded then to move its inner workings across to a Mini Pro core frame which is identical. The Mini Pro itself was dead. On taking apart the URSA MINI I find that the front piece which supports the sensor PCB and the lens mount is also substantially damaged with small pieces falling away.
The lens mount itself was loose but it may have been left that way following exploratory visitations. With this part having to support the weight of lenses, sticking together the many pieces of broken magnesium alloy castwork with JB weld won't cut the mustard.
It must have had a very substantial accident, like left on a car roof and fallen off type of accident or crashcam maybe.
I had hoped to transfer this entire front piece because the seal of the sensor and IR filter would not be disrupted by the move. It would also match the left side cover and monitor. However it is also fractured. So the sensor board itself has to migrate to the good URSA MINI PRO front. This is where it gets complicated.
The URSA MINI PRO front also contains a ND filter wheel assembly. The URSA MINI PRO left side cover and swing-out monitor is completely different with more electronic bits and pieces attached. The URSA MINI left case and its screen will bolt up to the URSA MINI PRO core frame but the added filter wheel assembly takes up more space and fouls the side cover.
The display screen connection appears to be the same however the touch controller may be routed differently. The ND wheel would be nice to have operating but the rest of the functions will be just ornaments in the side cover.
There is a lot of dust inside the URSA MINI 4.6K. It looks like it has faithfully earned its keep. The URSA MINI PRO case was clean inside but caved in at the right side cover with the main PCB having been sprung in at least 5mm inwards and then rebounded back. It seems unharmed to the eye but that smack in the gizzard was near the main processor with all its many little solder joints begging to fail.
I shall have to have a good think about this or pack all the loose pieces in a box and wait for some more busted URSA MINI 4.6K cams to come along in the fullness of time.
