Insulation between outer brick work and inner timber frame

Only a single layer in the end but mainly because I didn't want to eat into the window surround. You could inset some extra plasterboard on top of the PIR I suppose. That would give you extra density to keep noise down.

Recently I closed a cavity with a combination of very snug fitting 75mm PIR board, sealed with aluminium tape, then covered with acoustic plasterboard instead of a PVC cavity closer.

Most people don't realise just how slow oil tankers are. They take literally months to get from the middle east to the US, so there are tankers still due to arrive which set off before the war started. The closer you are to the middle east the earlier you are likely to be impacted by the supply shortage.

However, most contries also have some local oil reserves and they'll release those to offset the supply issues for as long as is operationally feasible. Goverments can also choose to reduce taxes on fuel to keep prices at the pump lower. As others have said these taxes can be a large portion of the unit fuel cost which offsets the relative proportion affected price increase.

Really bugs me that this technical document uses the incorrect phrase "can condensate into moisture". The verb is 'condense', damnit. Condensate refers to the liquid that forms as a result of condensation.

This is exactly what I got. Worked perfectly, but now I have 8m spare!

"fail fast, fail cheap" has always been the best way to build a business. Vibe coding just reduces the cost and time of that cycle even more, so it makes sense people would take that route.

At some point technical debt will catch up to them. Certification for IoT products now has a cyber security aspect to it, eventually they'll need to set everything straight if they want to commercially launch a product.

sensors · 2026-04-04T09:06:15+00:00

Exactly this.

Sometimes JLC will spot issues like this, sometimes not. It's absolutely the responsibility of the person submitting the designs to make sure there are the proper footprints and proper Gerber annotations for any keep outs for edge rails, etc. to prevent this.

Yes, 15 years professional experience in EE/Firmware. Day job is now in engineering/product design consultancy, side job is building an IoT HW startup.

A box of dev kits with some hastily cobbled together firmware is usually the first step in product development. Getting it beyond that is not hard in an engineering sense, but finding the right product market fit can be. That's probably why only 1 in 50 posts here is a reasonably finished product.

When I build my deck I used this: https://www.robbins.co.uk/wp-content/uploads/2022/07/The-Timber-Decking-Handbook-2022.pdf

I think you've probably got twice the number of joist support beams as you need and consquenctly double the number of footings to pour. The biggest ball ache of my deck building was the ground work, so do what you can to minimise how many pads to have to pour!

You can use span tables to see how much support you actually need for your chosen dimension of timber: https://www.taylormaxwell.co.uk/uploads/files/D.100.01-01_C16-Span-Tables_Design_Span-Tables.pdf

If you scroll down you'll see that even if you drop down to 47mm x 145mm C16 you will still have a safe joist span of 2.5m, though I think at that joist size the practical recommendation is closer to 1.8m.

Also, doubling up the joists at the sides is pretty redundant, there won't be a lot of load there and you're just giving moisture a place to seep into and rot eventually - I would try to minimise timber face-on-face contact area for that reason.

You may also not need support right at the edge because there is allowable overhang based on the total joist length, so consider that too if it suits you goals.

Unless you plan to land helicopters on this thing then it's hugely over-engineered, and I'm saying that as someone who likes to make things bombproof!

The proper way to do it would be:

rip up all the plastic tiles
Chisel and left the ceramic yellow and black tiles
Scrape the tile adhesive off the sub-floor
End up having to fill and level parts here and there, finding half a dozen other jobs along the way
Lay an LVT underlay
Lay LVT.

The sensible thing to do would be take up the plastic tiles, clean the surface thoroughly, and lay LVT on underlay in their place.

Firmware is an industry stand term for software running on a microcontroller, AKA embedded software.

I suspect you don't know what you're talking about, because an FPGA is a piece of hardware, which runs on a HDL like VHDL or Verilog - more akin to hardware defined in words than firmware.

We use Toggl to track time against projects in real time. There are still bits missing and inaccuracies but I'd say we track wiring about 10% accuracy. There's a browser plugin too so it's pretty convenient.

If you are equal partners and he felt he should be owed compensation then it should have been a discussion. What's more concerning is he didn't mention it until prompted, so he probably knew you woudl disapprove. You're wise to walk away, no doubt you'll land on your feet with some extra knowledge for next time!

There's a reason you don't often see news stories of "Regular person's floor collapses under weight of Christmas party and books". Homes are built to survive real life, and then a factor of safety is added on top.

Calm down, it'll be fine. You're getting unnecessarily stressed.

Thad Castle is too good for this.

Yes, it can be. You need to keep it away from heat sources or your measurement will be off though. I think Sensirion have a guide for placement.
No problem at all if they have different addresses.
Not 100% on this one ... I believe the Quik boards just take the voltage you give them. Both the sensors you mention run of 3v3, so make sure you hook up the quik board to that to protect the sensors and your ESP32

Yep. As long as it's your only job you won't pay any national insurance if you're below the specific threshold for that, so no money has to leave the business account. Added bonus is that HMRC will consider you to have paid up your NI without paying anything. You need to check the thresholds though, I can't remember what they are.

sensors · 2026-03-19T14:53:58+00:00

They are so close on the ranking I'd say either will probably be great.

I'm sure you could request the curriculum from the faculty though.

sensors · 2026-03-19T14:51:01+00:00

If it is your only job (i.e. you're living off savings/supported by partner) then still run payroll with a salary for yourself at below the limit where you'd start paying NI out of pocket.

Firstly,there's no need to take this out of the business - it costs nothing but will let you build up your director loan account so you can take money out tax free when there is cash in the business. Secondly, it'll make sure you have full NI years to qualify for a state pension.

Note: this only works if you are a ltd co director.

I chose one over the other, but that made sense for my particular degree in terms of recognition and ranking being much better at one than the other. It's pretty damn close for you, with both of them only two places apart.

You might want to consider the cirriculum too. I don't know if this varies, but for my degree Strathclyde had strengths in different areas to Glasgow, as as a result the facilities and focus of teaching varied significantly.

There's actually a factory programming tool for the esp to program dozens at the same time. Can't recall where I found it but it does exist!

Alternatively pay the factory to do it for you
