  We present a novel solution to automated beam alignment optimization. This
device is based on a Raspberry Pi computer, stepper motors, commercial
optomechanics and electronic devices, and the open source machine learning
algorithm M-LOOP. We provide schematic drawings for the custom hardware
necessary to operate the device and discuss diagnostic techniques to determine
the performance. The beam auto-aligning device has been used to improve the
alignment of a laser beam into a single-mode optical fiber from manually
optimized fiber alignment with an iteration time of typically 20~minutes. We
present example data of one such measurement to illustrate device performance.
