I just made another wood-mod with the 75C and one 26650. Not as perfect as I would like but it's all handcrafted.
It is oak and Grenadill. And it became big...
This is mine for now, the small one beside it is a DNA30 which I love and use all day. Actually I am building another DNA30 with an analog Poti for the Wattage settings. I made the DNA75 into a Golden Madrone wood block (carved by hand), it runs from two 18650 in parallel mode. Hope you like it.
