In addition to connectors, the speaker has assembled a collection of rugged racks initially designed for air transport, which serve as sturdy chassis for electronic setups. These racks, made from heavy-duty aluminum, can be modified with additional plates to create custom enclosures or platforms. The speaker envisions outfitting these with components such as power supplies, motors, and drivers—indicating plans to build or restore sophisticated electronic systems, possibly for automation or radio projects.
