Bluetooth controller / amp.

I need to order some M4, A4 stainless, cheese head screws:

Any chance of changing the thread title, it's foul! ?

You might start with a brick or block built shed maybe to get a feel for it? Or a barbecue before that! ? I've used a Bricky tool. Tbh it's a magic bit of kit and ensures full fill joints of uniform depth. But it's slow (then so am I). The bloke who invented it, Noel, is a top lad and approachable: I reckon his string line holder device is actually on par with the Bricky tool! I've built a shed dwarf wall. That and a couple of infill walls, it was used too for a mate's conservatory, in brick. Only really used it with Celcon block myself. I'm oddly anal anyway that I go over my joints with a mortar gun. Not sure I'd fancy building a house with one though people have. I'd say keeping the corners vertical so as not to splay in or out is the real skill the higher you go. It was hard enough doing my gate pillars recently. I made a jig for that. Don't know if it'd pass muster on the corners of a house!

The 1000uF Cin is rated at 35V. Happy enough about Vout as dictated by R1/ R2.

I think SWMBO is angling for me to install a hypocaust. Overheard her talking to a mate, something about lighting a fire under my ar5e...

SWMBO's having the first bath..nudge, nudge ??

Slack git, what with me finally sorting out the heating in my bathroom... ?

@pocster & @joth will be along in a mo with their HA controlled laser shows.

I've literally just ordered a 2VA 0-15V. A couple of mm taller. https://uk.rs-online.com/web/p/pcb-transformers/7320364/ Same 5mm pitch pins but the secondary pin out is different. I need to cut one track and bridge another. Should have the trannie on Tuesday.

I used cheapo stainless deck lights £4.99 for 10 and LED strip as well in the reveal. All the "power" is outside the bathroom.

The 4 diodes of the rectifier circuit check out OK. This then from the regulator datasheet: R1 in this case is 270R, R2 is 2400R. Not sure about IAdj so I just plumbed in 100uA as a figure. Vout then calcs as 12.6V.....I think?

See a couple of posts back.

I buy my ducting here: https://www.drainagesuperstore.co.uk/browse/underground-drainage/ducts/electric-cable-ducting-coils.html Also had a few bargains off eBay and Gumtree for part used rolls.

It's a no brainer for me. Run in duct, even SWA. Darn sight easier to replace/upgrade later especially where the capable goes through a slab. If a control cable running alongside mains then just put it in a smaller duct within the big duct. You will need to consider how to form an air / gas tight seal where the cable comes up out of the duct into the house. Some favour expanding foam then silicone. I prefer this as it's "re enterable". The last two ducted services I've run, new water main and new supply to gates, I've had to core through an existing slab. A mission in both cases!

Tbh I've only cut some Goldscrews down with it so far. Still handy for that. The recip saw has seen the most use.

There was a site I'm aware of where they switched from oil to gas. Boiler room was underground. The old old tanks got ripped out, new gas boilers installed. The plant room was tarted up, everything was commissioned and running like clockwork. What somebody had forgotten to do was cancel the bulk oil delivery. The filling valves had been left in situ, above ground in the plant room wall. The oil pipes had just been cut off down in the plant room but not capped. All was good until the oil tanker turned up and made its delivery at silly o'clock in the morning. When the gas boilers came on they were greeted with a boiler room full of oil vapour... I've known a guy involved with it for 20 years now. Not his fault it happened and he's a sh!t hot oil and gas engineer. Unfortunately because of his surname he's forever been known as "Bomber" Harris. I was introduced to him as Bomber, took me probably 5 years to know his real name.

I know somebody who's just run an oil line underground...in green hose pipe! ? (No it wasn't me!)

Don't some Scots DNOs insist on red ducting for electrical?

Mate's got it. Funnily enough the same lad who's trying to build a CNC table. (I gave him a CNC board @Jeremy Harris gave me as a weird aside).

@ProDave how can you edit and it not come up that you've edited? Mods privilege? ? It's a Carlo Gavazzi Dupeline FPD 1901 220 channel generator. Allows 8+ channel comms up 2 wires. Should be about 8vdc on the comms line. About 30 years old the tech. No big deal I can replace with an updated unit that's about 3 generations on from this. Carlo_Gavazzi-G34900000230-datasheet.pdf

Ta. No Variac here. Just the assorted IR, Ohm and clamp meters, RCD & loop testers. Plus various "multi' and capacitance meters.

Intact? It's swollen and stinks to high heaven! Crispy is the word I'd use! ?Meters I have here measure up to 200MOhm. Open circuit on primary. This is all I get on the secondary: Voltage regulator us an LM317T. Going to start drawing it out.
