That is a tough question for me to answer. It seems that just about every application in which I have seen encoders like this use indents. But I suppose there might be applications in which these would not be preferable. Maybe you can find two encoders that have the exact same footprint and mechanical specs but one has indents and the other doesn't? That would mean you could design one board (or perhaps use the board you already have) and just change the BOM.
This seems like a really cool device. But I am wondering, are there any plans to offer this exact same thing but without the LED?
I can envision quite a few applications where this would be really handy. But the price is a bit high if you don't need/want the LED.

I just want to be clear. Does the Neutis Development Kit include the Neutis Module or do you have to buy that separately?

Yes, good luck. I will definitely miss your videos and learning articles.

Having an option for the female connectors at the breadboard end would be nice.
Tutorial - SparkFun Inventor's Kit for micro:bit Experiment Guide
I was working through the experiments in preparation for working with my niece this summer when she visits. I found a slight issue with experiment 8: Using a Servo Motor.
The experiment shows connecting the servo power connections to the power rails of the Micro:bit. These are 3.3V. But the servo is more likely to want something closer to 5V. In my case, the servo behaved erratically. I tried another servo and that one did not work at all. I could tell it was getting the correct signal and power was connected. It just wasn't happy.
I first connected a capacitor in parallel with the supply pins of the servo. That helped a lot. But it still wasn't quite right. I then grabbed a breadboard power supply and connected the power pins on the servo to the 5V output. I then connected the ground of the supply to the ground of the Micro:bit. This worked perfectly: with both servos. The 3.3V signal from the Micro:bit was high enough to work. The servo just needed a bit more voltage for its supply.

You mention you will cover three ways to configure the PI. But I don't see a link or anything to the tutorial. Am I missing something?

I would be careful about advertising that maker map. I did not check all the sites. But the ones around the Austin, TX area are seriously out of date. Five out of the eight shown have no active web site associated with the web address provided by the tool (I get a 404 error when I click on it). One of these is the Techshop in Round Rock. I think just about everyone knows all of the TechShop's went bankrupt a few months ago. Another is a listing for SXSW Create. This doesn't exist anymore and the listing states it is SXSW 2013! The remaining ones don't really look like makerspaces. They look more like retail stores that provide materials for makers.
It is interesting that one makerspace that is still active in the Austin area is NOT on that map: http://atxhs.org/wiki/Welcome_to_the_ATX_Hackerspace_Wiki
Perhaps it is too new to be on that map?

How about adding some type of capacitive touch switch to either the candles or the flames? Then you could "light" the candles just by touching them. I would bet your niece would get a kick out of that.

I am curious about the large doll in the background. What is THAT?!
