This is a simple pencil rig i made in blender.
pencil rig v1 from Nathan Anozie on Vimeo.
These are some steps i took in making this:
making armature
2 bones midway
1 bone at origin
add origin bone so its translate channels match with world axis.
ex when its translated in pose mode:
duplicate origin bone twice to make mid bones.
make it easier to see mid bones ontop of each other (envelope view adjusting envelope/head/tail radius). view wireframe mode
parented one mid bone _b to second mid bone _a. parent mid bone _a to root.(select child then parent >> ctrl+p keep offset)
so move root moves all bones.
parent pencil mesh geo to innermost mid bone. select mesh then mid bone b then ctrl+p parent bone option.
-add widgets for bones
circle >> square >> triangle (from square merging 2 verts with alt+m >> center) (for making widgets switch to solid view to see faces)
assign widgets to appropriate bones>> check on display wireframe for bones. then put widgets in last layer >> select them >> m >> pick last layer
-clean up
make mesh unselectable (arrow icon in outliner)
switch to solid view
could hide relationship lines when done (in n panel >> display)
(on the side for making pencil >> started with cylinder >> adjusted dimension/scale to get rough proportions >> selected cap edge loop extruded with E (to select edge loop alt+rightclick on edge in edge mode) >> merged extruded vertices to center alt+m)
Happy Rigging!
