wow! congrats on getting all that together. I dont think I'd have enough patience to deal with that many tiny surface mount components. The one time I soldered a single chip on a Honda pcm using the heat gun, other pieces got moved around--explitives were necessary. haha

Hello Julian, maybe you knew this already but from Jan 1st all purchases we make through AliExpress etc will have VAT added to the cost. Did you know that? (Sorry - this comment is completely unrelated to this video!) Any thoughts on it? I just prepared an order for some of those small "360" buck converters (hence thought of you!) and the cost was a bit more than I expected. Seems like the days of nice cheap stuff from China are coming to an end?

I think you would find it easier to use solder paste and an SMD hot air station than a soldering iron. I remember you using soldering paste before (you made that paste dispenser pusher) so wouldn't that get rid of some of the frustration of soldering all those SMDs with the side benefit of keeping them all straight?

You under-estimate the power of water vapor! Condensation will get into your box from microscopic cracks around the cables, and create a humid environment with over 90% humidity. You'll see a fog build up from the inside when the dew point is low enough. The only way to stop water, is to encapsulate in something. Your little module is screaming for a little epoxy love. An old fashion match box would be a good mold. You must have $1 epoxy from your revision of Dollarama we have here? one pack with do all 3. Then you put it in your box, and that's all she wrote...

@@JulianIlett That thin film of vapor will corrode the inside with it 1-2 years. Video tape it then. I'd love to see the damage after a year. The problem is that condensation will get worse as time goes by. Funny thing about water, it gets everywhere, and loves dissimilar metals in contact with each other, to setup a galvanic all-you-can-eat buffet, and munch on ions, until no more corrosion to be had!

This is a good reason to have both a couple of drain holes and a small air vent so there is at least some air flow. It’s the high humidity that causes the problems.

I take it you used two different SOT23 transistor pad layouts because you had less room on the top? Did you try rotating the top side ones 90°? It looks like you would have more room that way without the "V2" label in the corner.

I still vote for using fuses on those big "outdoor" batteries. Even if you used just one "big" fuse at the battery and everything connected to it it would be much safer. Use a 10A fuse or whatever your max current needs and it would be done for everything you connect. It would also cover your butt for home insurance if your fence caught on fire next time. The cost is minimal for an inline weather resistant fuse holder assembly (wires and all) from your local automotive store. Better safe than sorry with those big bad ass batteries! 8-)

It has to be said, that if you use ceramic sand filled fuses, it does reduce the likelihood of arc damage should a short circuit occur. The short circuit current of lead acid cells / batteries can be hundreds to thousands of amps. And if the short circuit occurs very near the battery, it can cause the battery to bubble and either violently vent, or burst. And you don’t really want acid spraying out, it’s not very pleasant... I use high rupture fuses rated at 5A, 10A, 20A and 25A on my large lead acid batteries, depending on what the fuse is protecting. After the high rupture fuse, for the smaller loads (like LED lights), I use 20mm or 1¼” glass fuses.
