Part 5/7:
In one particularly nostalgic segment, the traveler recounts their experiences collaborating with sponsors for the development of these devices. They mention having up to five sponsors over time with investment ranges between $10,000 and $250,000. However, as time progressed, interest waned in further development or manufacturing.
An amusing incident is recalled about customs in Korea, where a customs agent appeared alarmed at the sight of the device, initially mistaking it for something dangerous. The situation diffused thanks to the intervention of a sponsor who provided a calming explanation, marking yet another amusing chapter in the narrative.
