Hello fellow e-foil builders. A new build from Norway.
A few years back, I started to build YAHS (Yet Another Homemade Segway). Unfortunately, that project was not very well documented. Couldn’t find an common place like this to share and get ideas, but here are a few videos of that.
YAHS Alpha, YAHS Beta, YAHS V1.0
Last year I saw a clip on YouTube of an electric hydrofoil and fell in love, so the dream of YAHEF (Yet Another Homemade Electric Foil) was born. Early this year I invested in a few basic things, like a 3D-printer and started to play with Fusion 360. During the year, more and more parts has been collected and now, I’m ready to start building and aiming to have my maiden voyage in April, May next year.

I will go for the Flipsky in my first build.

Battery
Using my old YAHS batteries for testing. Buying new ones later on.
Board
Chinese inflatable aliexpress.com. The only one they had was a sample, 180 x 72cm with 71x30cm hole. Ideally a smaller one is prefered but this one will at least get me started.

Well, haven’t seen any stock box. DIY is the way to go.

Remote Control
I’ve barely started with the remote control, based on @Hiorth design. The lid is changed to house a 320x240, 2.2 inch display and a navigation button. The goal is to have all telemetry, speed, heading, distance, remaining distance, various alarms, temperature on different parts and so on, available on the display in real time. More info will come.
