m-BITBEAM

This is source repository of m-BITBEAM parts. It is based on bitbeam-lib openscad library, which is append as sub-module under the scad directory.

Parts must be shifted to right position, to good positioning in LDRAW type software.

Parts naming

There is simple as could be naming key for files and parts naming. This could help you to understand what kind of file, resp. part is it.

bb-drv-mbkitronic-th
                   ^---- subtype if is needed
          ^------------- additional values of part
     ^------------------ type of part
 ^---------------------- main group or category of part

group

There are some main groups, the base group is bb, which means bit beam, so this is printed bitbeam parts. With ws group, only they are in STL release file.

bb - bit beam
co - complete part - typical bit beams with some other parts like sensor or special wheel supports.
nut, ws, sc - nut, washer or screw
sen - that is sensor
pin - plastic pin
shaft, t-shaft - shaft

type

Type of part, that could tell you, what kind of beam, sensor or driver it is.

a - L shape with defined angle
b - Beam
bd - board (Arduino, OctopusLAB, etc.)
gr - Gear
h, o, d - Beam frame with specific shape
t, x, u - Beam with the specific shape, which looks like T, X(+) and U
sen - Box for sensor, driver or other separate electric part
wh, pivot - Wheel and special stabilization ball.
tr - piece of track chain

subtype

Some part have defined sub-type.

sm - Smooth, that means version without too much holes.
th - Thin size, that means height of Beam is one half of unit.

value

Value is short as possible which represent specific of part. That means number of each beams - size, type of sensor etc. Examples:

bb-b-20x1 - Bit Beam 20x1
bb-a90-3x4 - Bit Beam L type 3 for one arm and 4 for second with 90 degrees angle.
bb-sen-rwc - Bit Beam box for rcw sensor
drv-mbkitronic - electronic part Motor Driver from Kitronic for BBC Micro:bit.
bb-drv-mbkitronic - bit beam box for motor driver
sc-M4x20 - M4 screw 20mm length

Releases

Avery tagged commit is released by Travis, and two "binary" files are created:

m-bitbeam-stl-X.Y.Z.zip which is printed STL files.
m-bitbeam-parts-X.Y.Z.zip which is parts library for LDRAW type software.

Authors

This work is created or based or more authors. So all parts is tagged as work of Collective Authors, they are in AUTHORS file.
