This is my newest mini, the "Crayola From Hell"

at the end you will want to put the endcap of the marker into the writing end cap and tape it because in the crayola markers there are holes in the cap, this will plug them

the last pic is this mini alongside its partner in crime "The Highlighter" with butane and ammo

tell me what you guys think

take the insides out of the pen and marker, keep the end cap and lid of the marker, you wont need anything from the pen but the tube

wrap tape around one end of the pen until there is a snug fit in the end of the marker (non writing side) stick in so half the tape is showing, and tape over that to hold in place

attach wires on piezo to t-pins, stick t-pins in marker so the gap is small enough to make a spark but large enough to ignite the fuel

thank you, The butane is the fuel
I do need to work on close up pics more, I should have used my new camera. It has a macro setting for better close ups
