The utility room

 And so it begins..

24/1 Cleared a bit more garage, worked out levels and soil pipe. From the internal wall, the slab is highest along the adjoining wall, so had to removed some floor, and trimmed 2; 1 10mm, one 4mm. The floor then sloped and lost 40mm nearest the car door, vs 25mm opposite the internal wall.

25/1 Cut joists, fitted hangers, cut insulation. Extra support under joists nearest internal partitions, and 1 under trimmed joist (-10mm, but calcs still ok) which sits under the washing machine.

26/1/21 Secured base to garage floor, fixed 2 hangers in the wrong place, fitted deck. Filled gap between house and utility (3 hours!) Ran conduit for new supply. W/m mains cut into deck ready for partition. 

27/1. Rafters are not parallel to house wall. Put up outside partition rail + some uprights. Wired the earth in. More screws required! Ordered workstops + cabinets.

28/1 finished base of internal skin. Put up 2 boards of external skin. Removed existing sockets off wall and put 3 new on 2 boards. Moved tools and put up a small bench.

29/1 pm doubled up 2 joints on osb. put up ceiling rails + some spans

30/1 corrected ceiling rail on outer skin - 13mm too low. 2 ceiling sheets. Internal PB rails and 1 sheet. Dis board, temp feed + 1 light.

31/1 finshed osb top/bottom rail, ceiling rail, ceiling spans. Cut all metal uprights, but several left unconnected to the ceiling to allow PB to be carried in and twisted easily. Ceiling FG + 2 walls (mistake - should have done this yesterday, but didnt want to get covered in FG) Run out of base rail.

2/1 --

2/2 loft tidy, fit remaining ceiling plasterboard. Ran in most conduits, pulled supply cables. Chased in sockets and fished between. 

3/2 move garage light switches  temporarily,  install outside water  pipe.  Clean wall, glue plasterboard (all afternoon for 3 sheets - use low expansion foam next time. About 9L of glue per board comes from 15kg + 9L water ie 15kg for 6m2.  Too much. Tried 4.5kg + 2L for 2m2 and still too much. Mix up pretty thick)

4/2 install sockets in glued plasterboard, build loo temporarily and set up waste.  Screwed down floor + finish floor around waste.

5/2 Cut light holes. Fitted rails for internal skin.

6/2 moved garage light switch from utility to garage with temporary extensions. Added permanent live to garage light and put in a socket. Put door opener back onto original trafo. Framework for lobby and temporary plasterboard. 1 sheet of plasterboard and osb plus insulation. Drilled hole and fed conduit for shed. Final piece of ceiling plasterboard fitted. Removed trailer wheel, tidied and moved all 12mm osb to be fully upright by screwing it to the last sheet. Most had developed a bowed middle. Moved remaining 7 sheets of plasterboard into the utility. Worked out where utility door will go.

7/2 --

8/2 fitted utility door and main door, boxed out frame, light switches.

9/2 Finished utility door. Fitted loo frame/door. Misc bits. Tidy. 

10/2 pulled all remaining wiring. Lights in. Looked at window location. pm --

 15 working days to date.

11/2 cut & glued plasterboard around arch. Cut frame for window. Cut a sheet of osb3 to finish run to door and wall above bench. Tested quick setting joint filler, about 8 years old and it was fine! Taped and jointed wall side of utility. 

12/2  pm stitch drilled for support below lintel. 26mm board, 760 long. Mortered in with fresh cement. 

13/2 Fished congealed lighting. Wood for worktop, wood for hooks, fire extinguisher. Finished hook wall (needs insulation) Finished pillar/ reveals. plumbed outside tap. Sealed gaps between slab and floor - removed plot and replaced with wood to allow better draught seal.

14/2 -

15 cut window opening, block hole, render up sides to fill gaps and tidy (red dust everywhere) 

16 make sides for window to make thickness to 150mm- oops should have been 163mm. Fit support on window underside.  Fit window. Test 11yo bag of Weber render by putting a scratch coat on the top reveal to fill in the large gaps.

17 1/2 day. tidy, fit sill, fit window. Bit of a devil as the frame twists, so catches on opening

18 2 layers of silicone around window inside. Framed and insulated. Worked out where basin will go.

19 pm install loo

20 am plumbing for basin

22.5 days to date

21-

22-

23 dummy install of pan. Seems frame is twisted and can't get pan level. Moved cooker and pulled back 15mm outside tap feed and rerouted it into utility.  Added 16mm per to hot. No joins. Fitted manifolds,  connected outside tap and loo. Tried drilling a hole through the bricks near the loo with the intention of leaving a threaded rod for future pan retention if plugs fail, but can't reach by about 100mm. 

24 1/2 day. Manifolds now live. Leak on soldered joint on outside tap,  but now considering moving tap to inside shed. Plumbed basin.

25 changed plugs at top of loo bracket to those provided. Much more solid than 100mm hammer in. Moved outside tap to shed. Glued most of sink waste. Fitted plasterboard around window and installed sink.

26 <1/2 day. Installed window grill, glued soil pipe. Replaced loo top wall plugs. 

The bricks have the first web at 40mm, so can use plugs of around 60mm ok. If they have anti rotation tags on the head, file a flat for them. 100mm hammer in dont work. 80 generally OK.

27 test soil pipes. Reinstall loo partition. Install light switch.  Chop 10mm off manifold brackets else worktop of 40mm may not fit. Metal for cistern partition. Hole for 32mm waste.

26.5 days

Diesel garage heater

There are a bunch of these heaters sold under lots and lots of names.

This one in for repair is a Kende spark 30, 28kW, on wheels

There was a small fire that ruined the wiring and destroyed the photocell (LDR) Parts are readily available in the USA, but not in Europe at anything approaching a fair price. The PCB got toasted when the wiring shorted to chassis. The PCB is live chassis. There is just an on switch.

Very simple operation. The fan and ignitor run all the time via a triac. If no flickering is detected by the LDR (either the flame or ignitor) it shuts down in 2 seconds. To reset unplug for 10s.

The LDR choice doesn't seem critical so long as its change off resistance is enough keep the schmitt NAND from triggering. See the circuit for some figures. I had to replace the Q3 transistors (generic BC547) and the IC CD4093

Grain mill

 Not a part 2 of the home made grain mill, but a how-to-use-a-bought-one

The wooden one I blogged about just wasn't able to crush the grain.


A cardboard chute to funnel the grain. A large socket on the wing nut instead of the handle.

About 30 mins for 8kg.

Plumbing

 Moved the Caleffi 533251 3/4 with manometer from the HW system to the incomer.

Turns out it was quite blocked. Fitted ~2012

Ordered another complete valve 533651 as  it was the same price as just the cartridge, and gave me more options if my body was damaged. RX a 2018 vintage. Thanks.

Use molegrips on the bolt head to remove it. Tricky enough in the vice. Will need to jiggle it a lot and lever it with a screwdriver. Can be removed in situ ok. Not a lot of water inside.

Tidy enough. Wiped the body out and put in the new one. A smear of silicon. A bit of chrome missing. New one isnt chromed. 

Cleaned the old one with carrefour descaler. 5 mins for the screen, and 2 x 5 mins for the body, turning it. Has dulled the brass.  In future try half strength for 5 mins.

Hedge

 Cut the hedge nearest the hoogle bed and the south one. 5 hours. Had gone wild with the damp warm weather. About 3m2

Then thinned the goat willow on the north boundary which was giving too much shade to the fruit trees.

Dyson Max brushes not rotating

 If the brushes on you Dyson hoover stop working, you've probably worn out a pair of contacts. Initially test the brush head. I used 16V as it was to hand. It takes ~1A. Polarity nmot important.

Follow this video https://youtu.be/UafhshE0Th8?t=120 and remove the clear dust collector (use the open button to first open the door, then press some more and wiggle and the container comes away, rotated around the front nozzle.

You can see the 2 contacts on the right. Clean and blob some solder.



If you pull the cover on the other side, you can test for a connection - about 5R, on the red and white twisted wires. There are also 2 hidden filters, so clean those under the tap, dry, replace.

Asustor NAS UPS

It's stormy here in the Pyrenees this year and we are experiencing a lot of brownouts. The brownouts are long enough that the NAS reboots and then grumbles for a while whilst it verifies all the files.

A small UPS was needed, but not something that is going to cost the planet. I have several UPS, mostly APC and they are shockingly wasteful. So much so, that I use the best one on the PC and turn it off when the PC is off. The rest of the time I don't care about the energy it wastes as the solar panels 'pay'

The NAS uses a 5.417A/12V external psu and a barrel plug. I contacted Asustor a few years back to ask what the tolerance was for the 12V input. They refused to answer the question. Reading between the lines, they didn't know. I guessed that the 12V was used to just power the hard drives. Picking a few SATA disks at random, the spec was the standard +/- 10%, meaning 10.8V to 13.2V. This almost fits quite nicely into a standard lead acid battery. Li-on is no good as 10.8V is pretty much fully charged.

The AS6202 takes ~1.5A at 11V, 25% cpu & ram, 2 SATA disks. Using a fully charged, 20 year old Yuasa 7Ah/12V (measured capacity 3.5Ah) I got the following. The battery was connected to a Y connector with the normal psu. A 1n5400 diode and a 2.6A fuse.

SLA 12.38V off load. 

PSU off. SLA 12.03V. Volt drop across ammeter 0.17V, across diode 0.811V. 10.98V to NAS. Bleed through diode when psu on <0.2uA

I'm not going to get a lot of battery back up, but brownouts are avoided. I'll charge the battery monthly (disconnected)

In due course (!) I'll put LVD protection for the battery.






Some of the items in the house are supported by a Victron Multiplus II which is semaless in keeping the power on, but not the NAS. The NAS is wired to the router, and the router is a lightning conduit. I don't want lightning to get to mul

Mains detection

A long story, but I needed to detect the position of the switch in the kitchen that enables the kettle to run off PV surplus. I'd always managed to detect it in software, but I now need the physical position





 Very simple. A 817 opto coupler. A 4n7-10n X/Y cap and 100R in series with the mains. A 1N4148 inverse parallel with the diode. A 22u tant across the output. Pull it high with a 10k to +5 and you have a detector that consumes about 100uW. Sure there's a bit of 50Hz ripple at 0.35V but it's well below CMOS threshold.
..1 month later
Seems I hadn't tested this across a big enough input voltage. At 240V, the opto output was falling between the ESP32 thresholds. A 18k across the 22u tant gives 0.9/2.1V. Just ok. Design needs a re-visit.

Hoover

 Last week the cordless Hoover made so much noise even ear defenders where not enough.

It was vibrating so much the dust box was coming off on its own.

Opening up didnt reveal anything, and the vortex/motor assembly was quiet once removed.

It was bought 8/6/2020. 2.5 years later and the fan blade was thick dust.

Motor part number.




Never did get to the bottom of the noise.
