I need help... (moving vlog day 1)

[James]

The day has finally come for Linus and Yvonne to move into their new house. It was challenging...

Let’s let everyone watch the video shall we?

[Reegan]

I think someone forgot to blur an address, unless it really didn't matter. I would take a screenshot but incase it was accidental, I don't wanna highlight where

[Amit Samanta]

What is the sound system they're  using?

[Persius25]

Anyone have any idea what shelving was used for the cat wall? Trying to diy something similar.

@LinusTech you mentioned that, the plumbers dont wanted to mount pcbs near copper tubing
actual plumber here: get a plastic box, and connect an earth cable to the pcb
or the water + copper will ruin it quick enough

Electronics engineer here.

 

Connecting an earth cable to the PCB won't really do anything as far as corrosion resistance goes.... _{(Grounding a board doesn't stop galvanic corrosion from happening, in some cases it can worsen the effect to be fair.)} Secondly, galvanic corrosion is only a problem if the board is submerged together with the pipe, but submerging electronics is often not a wise move to start with. _{(the wires out to the vales is often also galvanically isolated if they are solenoid valves, if they are servo valves then it can be a different story.)}

 

Grounding the board for electrical safety reasons in case the PSU fails is however a different story.

 

In regards to water damage however.

Putting the PCBs in an enclosure to protect them from potential leaks is a wise move, and I won't say anything against that. _{(but the "or the water + copper will ruin it quick enough" is an inept statement for the shown installation.)}

 

Condensation from the pipes dripping onto the boards is also not a worry, since under floor heating systems are warm, condensation rarely happens on pipes used in these installations, for the very fact that they are above room temperature, or at ambient if left unheated during summer. Never do they get cold enough to go bellow the dew point. _{(if they get cold enough to go bellow the dew point, then the plumbing is incorrect. Since "underfloor cooling" is wonderfully inept to the point that cooling more or less always is provided by a separate system, with an exception for ice rinks.)}

 

So other than leaks, there is no reason to water proof these boards any more than they currently are. _{(Especially since a lot of "water proof" enclosures tends to trap moisture and make corrosion worse... So my recommendation is a splash proof one.)}

Wouldn’t conformal coating provide at least a “better than nothing” water resistance to an otherwise bare board?

Conformal coating is usually how PCBs are protected from water out in the field. Since water has a large tendency to get into any enclosure over time. _{(unless one also includes a properly dried desiccant. But I wouldn't call conformal coatings "better than nothing", I would call a water proof box as "better than nothing" while a conformal coated board is "the correct way to do things." but an appropriate enclosure is also usually desired, if we are talking about water proofing electronics in a marine environment that is.)}

 

However, conformal coatings have some downsides, usually that it is a pain to remove when one has to repair a board. And it usually also provides poor protection for connectors and buttons. But that is a risk one has to take.

 

But for the boards in the video, a splash resistance box is already overkill.

 

Since underfloor heating systems aren't really all that pressurized and won't leak like other water pipes in a house would. _{(some intentionally are having a slight vacuum on them to make leaks go into the system instead of out. And then one can have a pressure gauge to inform of any increases in pressure and potential leaks.)} And they also don't have the issues of condensation, so yet another thing one don't have to protect them from.

 

In short, there is a larger risk that the pipe to the nearby boiler bursts and sprays water onto everything in the mechanical room, not just these two cheap relay boards but also the ubiquity switches, servers, UPS _{(even more at risk if the leak leads to a couple of inches of flooding)}, and anything stored in there as well.

 

So I frankly wouldn't bother about water proofing them in the slightest. They aren't much at risk, nor are they controlling anything exceptionally vital. _{(since one should generally have an HVAC system to account for the exceptionally slow nature of underfloor heating.)} And it isn't like a lot of other stuff in the same room isn't at a larger risk as is, so the water shielding priorities might have to look elsewhere if one deems such as an issue.

I saw what you're talking about and it said Ontario, so not his home address.

[dsteketee]

So what are you using to control the AV equipment remotely?

[Arika]

I'm really starting to like this Dan guy, perfect amount of sass and dry humour 

[Zodiark1593]

I’m willing to bet that quality control caught something that needed blurring before release, hence the late release. 
 

My bunny would love to have been the one dismantling all the packaging material. Should’ve asked me to send her over.

(warning, may damage the baseboards, and you may find random pellets on the floor)

[OppugnAll]

Might better in later video, but did anyone catch which SecretLab chairs they're using, I was considering purchase. Didn't know if should go leather or fabric, current plan leather for spill resistance.

[tkitch]

Can anyone explain why, in a theater that they're trying to make as DARK DARK DARK as possible...  There are a buncha chairs with GIANT GLOWY RGB STRIPS UNDERNEATH THEM.

 

Seems counterproductive.

[Alex CS]

Does anyone know where to get those theater seats? They look amazingly comfortable

They said it was Valencia chairs so presumably anywhere that sells the chairs seen here.
