The radio is built along primarily functional, industrial lines; inspirations include aerospace hardware, military/government radio equipment and also Japanese Samurai swords. The radio is built around a standard stereo FM circuit board, connected to two analogue dials for volume and tuning, an internal battery recharged by a standard DC jack socket on the rear of the case. There are two speakers mounted coaxially at opposite ends of the casing in order to maximise stereo separation, facing outwards into omnidirectional deflectors.
The speakers may be fully retracted into the two halves of the telescopic tubular casing, and the deflectors form caps to seal off the speaker tubes. The tubular casing halves themselves slide inwards to completely cover and protect the recessed control panel and charging socket. The speakers may also be left open and listened to with the control panel closed.
The materials are polished black polycarbonate for the main cylindrical walls of the case, the end caps and the stand, anodised aluminium for the tubular bezels, speaker mountings, PCB bracket and control panel, and polished stainless steel for the control knobs, finger guard rail, handles and machine screws. The stand has black, synthetic rubber feet, and black, synthetic felt lining its upper surface, both to protect the polished finish of the main casing and to afford sufficiently low friction for it to be slid open and closed without lifting it off the stand. |

| Comments on methods used: |
Rotational sections; additive and subtractive extrusions; shells for outer casings; patterns of holes for the speaker grilles, mounting screws, control knob grips and slide bearings; swept sections for the finger guard and cap handles. Custom materials created with varied colour, pattern and reflective properties and assigned to various parts; all parts assembled and constrained, exploded and unexploded, for final presentation renderings; 3rd angle orthographic working drawing produced to scale with dimensions and hidden lines, with additional isometric overview without hidden lines. |
