Got my TE dual mod done today. Took me 5 hours from start to end (including setup & clean up)
The mod was successful but I did make a few mistakes. As sad as it may sound the only stuff I messed up on was the EASY stuff. I was in a rush and working in a office so no proper work area. When drilling the 24mm hole for the button on the far side I only eyed it and my forstner bit must have moved some so my final hole is about 1cm lower than the other 2 stock holes. Thinking back I should have drilled a pilot hole first.
The next big mistake is also the hole, it was taking forever with the forstner bit so I hit the throttle and went to super speed with my drill and melted the plastic, the big pile of plastic shavings that came out of the top was hot enough to merge with the outside bezel, so when I was done drilling I had this excess plastic that I had to sand away, so I got some scratches on the case from that. It really melted on there good, normally you can just break away plastic that has been cut but this was bonded.
Last mistake was messing up the artwork on one of my buttons, I took the buttons off to add some double sided tape so it would not spin anymore. I took my time on all the buttons until the last one, rather than pry it up with a screw driver and my finger I tried to use two screw drivers and it slipped so I bent the artwork for that button and now if I look for it I see the crease.
Other than those 3 things the mod came out pretty pro. I put the Cthulhu behind the terminal block for the buttons, that 1ft RJ45 cable probably would not have reached had it been on the other side of the TE PCB plus it actually worked better there.,
My unit was just COVERED in the red locktight stuff and glue on the connections, it took a very long time to get all that stuff out but luckily it does come out if you get it just right.
When I was finished at the 5 hour mark since I was at work I had no Wii/Gamecube to test the only cable I had made so far, so I went ahead and used up one of my generic white USB A-B cables to make a USB cable to test. I plugged it in for the moment of truth and it did not work… was kinda bummed out, but figured everything was ok and it probably was the cable. I tested it with my meter and sure enough one of the wires was not far enough up in the housing, so cut that one off and attached another one (this time without stripping the wire first, I assume I had the blade type connectors that will cut into the wire making it a lot easier to stick up in there) and 2nd time was the charm, lots of beeps as stuff was installing, a failed install warning (kinda was worried) but when I looked at my devices list the MC Cthulhu was on there and every button works fine.
Pretty sure none of my buttons are mixed up but hard to tell.
The 30Ga wire was a pleasure to work with, glad I got it, when turning the PCB over to mount it would have been a lot harder with ticker wire. My soldering iron was broken the tip as loose and moved about 3cm side to side so this effected accuracy and heat to the iron but I used it anyways as I was not willing to wait another day to do the mod when I finally had a chance.
Sorry no pictures of the work in progress I was rushing and too busy focusing to take them, but will get some final product pics up at some time.
