A shortish maintenance video where I replace my Falcon's original fan, reflow the solder points on the back of the expansion port in the hope of improving reliability and have a chat about the latest version of DFB1 (revision 4) and try to figure out why it might not be working...
0:00 Introduction
1:20 Quick aside about the DFB1r4
1:50 Removing the bottom case
5:33 Starting to remove the bottom shield
7:45 Random reminiscence of taking the Falcon to university
11:06 First time board bottom reveal
12:00 Changing the fan
21:50 Removing bodge wire
24:40 Reflowing the expansion connector
30:21 Buzzing out the DFB1r4
35:21 Fail!
