So, I love the form factor of the iStick 50 and the 4400 mah battery life, but would like to start tinkering with nickel coils and the temperature control of the dna 40 chip. Has anyone tried to retrofit an iStick 50 with a dna 40 chip, or any idea how difficult or even dangerous this may be? I am confident with soldering, as I have made guitar effect pedals and wired electric guitars in the past. Any insight would be appreciated. Thank you in advance.
