Hello FC! As a long time lurker here and on several other threads, I have found this forum and everybody's input very useful. Now it is time for me to jump in.
I received my E-Nano from Andy about a month ago, and I absolutely love it. It has been put through its paces as my daily driver, and exceeded all of my expectations (which were high, based on everything I had read here).
I have only one small issue, which is that the connection between the main A/C wall plug and the dimmer switch seems to be a bit finicky, for lack of a better word. When picking up or setting down the Nano, the light bulb will occasionally flicker or momentarily go out. Wiggle or reposition the power cable a little bit and it goes back to normal. I have not been able to get the light bulb to stay off for long enough to test whether or not the heater is affected. Aside from being a little annoying, this issue hasn't affected the overall performance of the unit.
I was able to isolate it, I believe, to the dimmer switch, as when I set the unit down on a flat surface and wiggle the power chord immediately on either side of the dimmer switch, this is the only way I can recreate the flickering problem, and even then it is very intermittent. The connection between the Nano itself and the power cable is very solid and does not produce the flicker when agitated.
I took the back panel off of the dimmer switch in order to test the voltage throughput, which at level 10 came out to about 115v. Can somebody tell me if ~5v is a normal margin for error? I was using an older voltage meter which may not be of very good quality.
While I had the back panel off, I noticed that one of the 4 solder points on the back of the dimmer switch looks different than the other 3. I suspect this to be the source of the flickering problem, so I snapped a couple pictures. I'm hoping this may be as simple as either touching up the solder point or replacing the dimmer switch. I have checked on it several times over the course of the month of regular use, and it looks the same as it did the first time I looked at it, which indicates to me that it is not degrading from use and is safe to use.
I have seen that some of you are pretty knowledgeable about this stuff -- electrical, etc. I am not! Please chime in and let me know what you think. I have also e-mailed Andy, and will let you all know what he says when I hear back. Thanks in advance!
