Turns out that this is common in Japan for tea fields. They mount big fans on poles all accross the field for it (you provably have to zoom in to see them)

Hey! Props to you for trying something new. While the through hole components look OK, soldering large gauge wire can be quite tricky, especially if the soldering iron is not powerful. What soldering iron do you use? In these cases especially, it is important to wick the wire first, wick the soldering pad and finally assemble the two. Raising the iron temperature for this can also be useful (I sometimes use 400° or a bit higher). It is counter intuitive, but hotter iron means quicker soldering job, and less heat in the surrounding area (e.g cable’s insulator)

The green and orange colors are quite typical of the phoenix contacts brand. It’s not a perfect match, but this model is very close: https://www.phoenixcontact.com/en-us/products/printed-circuit-board-terminal-sptaf-1-7-35-il-1861988

For edits whithin a page, I use inkscape. Both program combined have covered all my needs until now.

Looks great!

If your are looking for pur aesthetics, I would recommend trimming the resistors/leds, and bending their leads before putting them on.

If you’d like some inspiration this guy has some of the best looking hand crafted electronics I’ve ever seen.

Nice! Could you explain what it is or where to find more information about it? I was not able to find information online

We are working towards having a product properly packaged. This is a prototype that is not mature enough yet to justify the cost/time to package it. Moreover, this custom chip is used to measure ultra low currents (down to femto amps), so any packaging could potentially interfere with the measurement capabilities (-> no epoxy). It is however protected by a large shielding box, but it’s no use during assembly/modifications :/
