I built my HM 4.0 almost 6 years ago and it has worked great but I have always wanted to add one of the damper designs. I finally have my 3D printer tuned up and printed the AdaptaDamper. Since it uses an RJ45 jack, I really wanted to figure out a way to use an RJ45 jack on the HM as well. I used the guide to solder the wires for the servo and attached them to an RJ-45 jack. I tried the 4.1 and up pinout but the fan would run full speed and the power supply would brown out.
Then I found a thread that discussed how the HM 4.0 used the neg terminal on the fan to control the fan speed. Since the 4.1 and later pinouts use a common ground, this is why I was having issues. I ended up using a separate wire for the negative terminal for the fan and hooked it up to it's own wire in the RJ45 jack. It works perfectly now!
I ended up finding enough room to cut a hole for the RJ45 jack in my current case and have all the functionality in my original HM. This is sweet. Going to smoke up a brisket next weekend to try it out.
Thanks Bryan for continuing to work on this project!!
Here are a couple of pics of my AdaptaDamper and HM with the RJ45 jack.
