seaside visit

The beautiful ocean…..

speaking of which, I am planning a build a unmanned surface vessel to deliver cargo to my friends, because I want to save some postal fee. For 1.67 USD, you can deliver a cargo under <2 kg to my friend’s nearest 7-eleven? nah that’s too expensive for me.

so here is my plan:

maybe add a solar panel on top for recharging during day time.

this basic design can allow me to deliver not-so-important cargo to my friend with the high risk of losing it….

Well, sometimes 1.67 USD is a good investment.
