These are very handy. They are simple angle brackets with one threaded and unthreaded hole. Use them for connecting PCBs at 90 degree angles, mounting accelerometers, gryros, etc. They can also be used on the universal plate set for mounting all sorts of sensors and such.
These are clear, self-adhesive silicone bumpers 8mm in diameter and about 2mm tall. These bumpers raise your PCB or project up off your desk which helps prevent short circuiting from bits of scrap wire floating about or setting a project down on a conductive surface. They also prevent your enclosure or PCB from sliding around. These clear silicone bumpers...
Metal long standoffs: 1" long x ¼" OD. Used to get your proto board up off the table. #4-40 thread. Fits most development boards with available holes. Don’t forget the screws, found below.
The elbow hinge allows beams to pivot on the edge of the profile with about 180 degrees of rotation. In other words, at fully-closed the two beams will be parallel to each other. The bushing that connects the joint works with a 3mm OD shaft if you want to run a shaft through several joints.
Actobotics is a robotics building system based around extruded aluminum channels, gears, precision shafts, and ball bearings. Thanks to the two standardized hole patterns, nearly all Actobotics components can be intuitively connected together. The wide range of components makes building complex electromechanical prototypes or finished projects a reality.
