Saw an eFixx thing on this recently. The person they were talking to was talking about how important it is to match the connector manufacturer and crimp tool as while it should be a standard there are tolerance errors that have caused fires. I don't know how much to trust this as eFixx can be a bit of a sales thing for manufacturers pushing their product but definitely worth paying close attention to. MC4 connectors are a common cause of issues.

Any love for CCT (i.e. changeable white) LED strips?
-rick- replied to Alan Ambrose's topic in Lighting
If 4000k works from dawn to dusk for you then yes that’s a cheaper alternative. I’m mostly a night owl too, but I think there is value in having a way to subtly wind down near bedtime and the older I get the more I realise how lighting impacts that. absolutely. Mismatched temperature lighting is awful. Bulbs is the difficult aspect. LED strips are cheap and easy to do as CCT but I’ve still not settled on the best way to do temp changing bulbs as I’d rather not have smart bulbs but smart controllers, dumb bulbs. After the last conversation we had on this topic here I’ve started considering buying non cct bulbs and gutting them to replace the LEDs with CCT ones and controlling them with a custom controller as mad as that sounds because I’ve not seen products that do what I want. -

My aim for any new install is to have cct lights. I want them for three main reasons: 1. As dawn simulation to help me wake up even in the middle of winter with dark mornings. Using home automation to gradually introduce light over a period of time before the alarm goes off. Used to have a wake up light that does similar but expect an installed version with bright LEDs to be better. 2. As daylight augmentation during winter. I hate the dark days when cloud comes out and it’s dark enough inside to need to turn the light on but when you do the lights have such a different tone that I feel it better to close the curtains even hours before dusk. Again with automation and light sensors I believe it should be possible to have the lights turn on ct matched to the daylight and boost the light without feeling the jarring effect. 3. As dusk simulation. As per (1) but the other way round with ct moving from cool to warm as the evening goes on and help the body naturally prepare for sleep. In this case it’s moving dusk later during the dark months. * I’m not really bothered by multicoloured lights though do like the idea of having red low level lights come on dimly if I wake up and move around in the middle of the night. Suspect not worth the hassle and will just use very dim white for this. -
Well Blue Origin just landed their rocket on their second ever launch so a true competitor to Starlink might not be so far away.

I don't feel particularly well equipped to comment in detail on this but have to say that this doesn't feel 'right' to me. The upper level of the entry way just feels wrong and out of proportion. This is not my area so don't pay much attention to my ideas here but things I would try to see if it helped: 1. Reduce the size of the upper window significantly 2. Replace upper window with multiple smaller ones 3. Use a wider front door (possibly door with side lights) or add a window beside the door 4. Replace the canopy/wall with something softer/less boxy 5. Windows on the sides of the bit that sticks out (possibly in lieu of front windows) Overall, the original plan seems better to me but I do get the massing issue that others have raised and it could do with some refinement.

Combined client/bridge or bridge/access_point

The simpliest way should be to disable DHCP, make sure the IP address on the router is set to something that doesn't clash with the rest of your network (on the same IP range/subnet) and then move the ethernet connection from a WAN port to a LAN port. That should be it. -
Insulating a shed for laundry room?
-rick- replied to flanagaj's topic in General Self Build & DIY Discussion
You'll have electric in there so can put a tiny thermostatic tubular heater in there on a low setting keep as insurance for the really cold days (wont be enough without the insulation though). -
Welcome! That's an unexpected combination I have to say! 😆

Sunny Boy SB3.0-1AV-40 continually rebooting

Upon reflection I feel I should clarify this. All the 'transformerless' inverters I've looked at in detail in fact have transformers but I'm not saying that there are zero truely transformerless inverters out there. Electrically it's possible to create something truely transformerless. Transformerless has been used as short hand for 'doesn't have the whacking great 50Hz transformer'. -

I'm pretty sure you and Steamy know this, but transformerless inverters are not transformerless. The transformers are just smaller, higher frequency ones. The amount of isolation provided is down to the manufacturer and is a separate parameter. High frequency ('transformerless') inverters have got a bad rep, because it is newer technology and plenty of manufacturers made mistakes in there design but I think we should be at mature technology now, and the efficiency and weight/size advantages are not to be sniffed at. Victron who for years made a big fuss about how their traditional low frequency inverters were so robust have now launched high frequency inverters (MultiRS/InverterRS) and have stated that they are now comfortable that the technology is robust enough (though admittedly even their first revision of the MultiRS apparently had issues). Most newer inverters now that promise high efficiency >97% are likely to be high frequency as low frequency has inherently more losses. -
They realise that they are far behind and if they don't start building a network (and learning how to run it) they don't stand a chance so yes they are throwing money at it. But my general concern with them does seem to be that they have too much money so are building very traditionally and not doing much different from the Boeings of this world. I expect that will mean that even once they have a reusable rocket it will still cost a lot more per launch than SpaceX and they will have to spend a lot more time and money fixing that (if it's fixable). Even their pockets aren't deep enough to launch 10's of thousands of satellites using those high cost launch platforms. Amen, though don't expect the Chinese systems to get licenses to operate in the west (and that brings up another point, Starlink has been buying up all the radio frequency licenses building an even bigger wall around themselves).

Not sure how relevant this is to self-builders as I haven't seen their name come up here, but I'd guess any reduction in capacity has knock on effects: https://www.constructionenquirer.com/2025/11/04/building-control-giant-assent-ceases-trading/

I doubt any competitor will be truely competitive until they are launching on reusable launchers (like SpaceX). Before that the costs just don't add up. Other reusable launchers are coming (Blue Origin has its second launch scheduled this week) and RocketLab are working on one but SpaceX has a very large head start.

So long as you know what you are doing. From experience, you are going to discover something that doesn't work through double NAT (wifi calling, video conferencing, some random app that you need to make something work) at the most inconvenient time and have to rush to rejigger things. So I suggest grasping the nettle earlier at lesuire rather than in a frustrated hurry after wasting a couple of hours trying to figure out why it isn't working.
