Few of interesting notes:
Bic lighter middle dimensions: 66.625mm Highx25.4mm wide with a unknown thickness(not necessary at this point)
Battery compartment 50.8mm high, 1in wide, Unknown inches thick (do not care at this point). (modification to host required)
Module front measurements: external diameter Tip 12.4mmx9.525mm total height with a unknown diameter around the "screw on part" (will measure later) (modification to host required)
Button push momentary dimensions: 6.35mm diameter x 6.35mm height (external portion) Lead height roughly 3.175mm (internal component drilling required a 6.35mm diamiter drill head required.
Rocker switch replaced with mini-slide switch dimensions:
width<25.4mm (improvement) height~=6.35mm not including leads which are roughly 3.175mm (extension of host required by 3.175mm) thickness: very tiny compared to apparent thickness of host. Major improvement.
Wiring will be located on one half of the host (shown in picture i will add to this post)
Driver location: 2 spots available:
1 spot: on top of modified location for battery compartment (tight fit, modification might be required)
2 spot: behind the battery compartment only slight modification to middle of host required.
So far so good, just waiting on my sled.
