Yes,the wiring configurations pictured above seem to be the most common ones.
I also have an older Nug Smasher kit which seems to use the "china/high5/qshop " wiring.
b2cvape replied and said they cannot produce a deep coil for the Graveda kit, and also confirmed that their coil is of similar depth to the Dab Ready coil (around 17mm). I will order that coil which will fit the Nug Smasher controller and report.
To repeat previous comments:
The Graveda kit has a shallow coil which will work but will need high coil temperatures, unless I produce a shorter version of the TB 202 for this coil.
This won't be any cheaper as the factory charges the same whether the piece is 18mm or 15mm long. I don't know if using the coil at near max temperature is OK in the long term. I guess it will have a shorter life span.
There are a couple of things I was not aware of before embarking on this project:
-the coil depth variability
-That China also has spring holidays and they are not working 24/7- who would have thought!!
So I've taken a short break myself to assess the marketing situation with this project. People are not biting with the pre-orders as I had hoped so I will have to take a risk and fund the first batch out of my own savings, and then try to sell it .
If i do that, I may have to take a different approach to selling this product- and possibly not through this forum as the stakes are different.
I know that soon after there are images of the product, some rodent will get it (badly) copied, as has happened with the Qshop products (which are themselves not exactly original!). I have spent a lot of time and money on this and I am not about to make it easy for them. It is unfortunate I cannot edit my own posts in this thread, which makes the forum even less suitable as a place to promote products like this, which are not easily patented.
So I cannot show the prototype here at this point and this creates a bit of a marketing problem
