The “Mr Redox” Home Energy Reactor (by )

So, I work from home, which means I spend a lot of time in my workshop.

It's a long, thin, building. The door opens into the metalworking area; moving along the building, we get to the electronics bench, then to my desk. As I've previously mentioned, I want to redesign the place a bit, but I'll still be spending a lot of time in here. I have insulated the roof successfully, but the second front in my war against chilliness is my rocket mass heater.

Death Head (by )

For the last year - maybe a little more I have felt that I am dying - I don't mean the ageing existential dread - I mean the feeling that my blood was thickening and clogging, as if it had hooks and barbs, but that if I was to get cut it would just bleed and bleed and bleed, that my heart was struggling with every beat but that there were so many of them that it might explode with the effort instead. My lungs have been fire, my ribs still hurt to breath as if I am breathing nothing but acidic smoke or drowning. My back hurts in new and unexpected places and this dull ache reminds me of the infected kidneys and sure enough my water works are... not right. My head often feels like it is literally being crushed or that ice water and electricity are somehow being poured into the brain casing. Then there are my muscles - so week, and crampy, twisting into painful shapes if not just the extremities going numb or tingling sometimes changing colour to match. My body feels like it has been shutting down whilst running the engine at full throttle. I actually feel like I am vibrating sometimes, my sternum is sore and even between my ribs... if I cough its like there are bands of barbed wire wrapped around too tight. And my eyes feel like they are being pushed out of my head by thumbs pressing in from the inside of my skull. My bones sometimes feel like they are splitting apart and even my teeth and scalp hurt. This is of course all on top of the pain I already had from old injuries, the chronic pain, migraines and the womb of doom.

It feels like I've been dying by degrees. Not helping this is the fact I do also have the existential dread - I have just had two and half years of everyone dying - so so many friends and family and the miscarriages and the almost dying myself. The spring especially this month is particularly horrendous for anniversaries and rememberings - including dad's and of course my last outing before illness and Lockdown was a funeral - the world beyond my door is filled with death.

But the absolute worst thing about all of this is that I can not dismiss it all as a panic attack - I did that in the summer and ended up being rushed into A&E - I am lucky I didn't have a proper heart attack - I am lucky once more to be alive. My heart really is struggling, I have been quiet sick since the miscarriages and then caught flu and/or covid on top. I have had seizures and my eyes are actually being pushed out of my head by the muscles at the back of them inflaming. My blood is clotting in a non good way and then not clotting when I need it to seal a wound. My breathing sucks - I sound like my dad who had COPD. My poor body is being pumped full of adrenaline so it is running at full throttle and it is tired - I am literally shaking myself apart like a poorly maintained piece of machinery.

I spent most of last year being unable to sleep flat due to my lungs and my hair keeps falling out.

I even got new allergies and warning sighs that my body was trying to reject parts of itself - like during my pregnancy with Jean - then there was the yellow skin - to go with the red blotches and weird blisters.

For 3 months last year - starting around now - I could do nothing much other than survive and since then basic parenting and washing myself have kind of taken up ever ounce of energy. My eye sight and hearing have both been affected and this too is not helping - it makes it like the world has receded from me - even with my new awesome glasses - and that is how ill I have been - I haven't even properly shown the world my fabulous sun glasses. I have been unable to write or draw or even craft - I began making tentative steps back to the things I love doing in the autumn but it seems like such a steep climb. Two weeks ago I attempted and completed my first commission since March last year - I managed it - I am starting to fight back - but it is unbelievably hard and I do not know where the bounders lay between physical illness and say - not seeing any of my friends for a year - most of them more than that as my mobility has been shot since the miscarriages.

The kids are helping me - we have started a family art club but I am feeling like the worst fail parent as my 15 yr old cooks food to feed the family whilst attempting GCSEs and the 10 yr old gets into trouble at school because they are obsessed with death and won't shut up about it. They both thought I was going to die and Mary got to see a full blown seizure and didn't know what to do and went to get help but everyone thought they were just doing a please play with me and so she came back and sat in the room telling me to stop and asking if I was ok and it was awful. And the poor Alaric too - they have had to take on everything -- including the basics of looking after my mum and trying to work and fill in the gaps of homeschool I got too tired to do - and there was a lot of it - I fell asleep in Mary's school club zoom. Alaric had the horror of watching me decline once more and feeling that everything is balanced on them and their ability to work and look after and fix and clean the house.

Alaric is somewhat crushed and I am more than aware of this and can do nothing other than attempt to make occasions out of everything. So today I am making a "Fake Away" of the King of the Golden Archers variety - so nuggets and burgers and milkshakes (yes that is me mucking around with the concept of Burger King and McDonalds!). The kids actually like helping with these events and tend to do their chores without arguing and they also know that these things sometimes get postponed if I am too ill - hell Jean got her birthday cake last week - her birthday is in August though Mary's happened on time - though her cake was rock hard in an attempt to make and not buy when too ill to really cook - she loved it and has been eating it with dairy free custard. This is how I fight back - it is a little lame that is true but then I am a lot lame.

But also the last couple of weeks the feeling I was dying started to lift. Obviously the seasons and things are changing so it could be the sunlight - but then I had the summer last year so I don't think it is that - I think that maybe all the medicine and things are working - I am classified as extremely clinically vulnerable and as such have already had my vaccine - I should have had weeks before I did but I got confused as I am trying to deal with 5 peoples worth of appointments and some of the clinics over lap. Three of the household are taking medicine and three are attending clinics - there isn't a complete overlap of the two groups either. Both kids now count as SEN I think and Jean is being supported by young carers.

A phrase keeps getting stuck in my head the Gloucester themed Beatrix Potter story - "I am worn to unravelling" - I am worn to undone - but the fight is on.

I now weigh the most I have ever weighed outside of pregnancy and that is some feet as I lost a couple of stone during the fever etc last year - so my weight has seriously been fluctuating with a 5 stone difference - I realise part of that is the thyroid meds (as in you can lit chart it to the dosage) but a lot is also my mobility (and maybe too many FakeAways coughs) and I was over weight to begin with.

Part of my fight back is trying to exercise - but seriously it is like trying to run a marathon every day when all I am trying to do is get up the stairs :/ but I am currently managing 3 odd km with crutches or half a km on the treadmill with out. I am using gaming (PokemonGo) and bribes (medals) and do gooding (charity challenges (or rather will be for this one)) to get moving again - before they went back to school the kids did PE with Joe with me and we found another youtube who does work outs to musicals (I found these easier to get into than Joes stuff that is obv aimed at the smol peeps).

This week has only involved one lot of blood tests and a panic at remortgaging - I have turned 40 and didn't get to have my big party but I got a purple coffee machine and though I am worried about the amount of waste it produces I have to say it is currently being my go to when things get too hard and it is like having a coffee shop in my home and mum only really likes coffee shop hot drinks anyway... we are struggling in every way except money at the moment - which is weird and I have to say money has definitely made a big difference and I can not lie about that - I have the home coffee shop set up and Netflix and iPlayer and Prime and Crunchy Roll and an epic gaming set up like we have never had before. But I often think that somewhere there is a me - trying to get through all of this without those things - and I have been in that place and in such a place it was impossible for me to fight back and all I could do was survive with lots of help. And so I want to help others - I have been trying - we have sent food and money to food banks, given resources to scrub hubs and the Hackspace to make PPE etc and I made halloween parcels for friends I thought might be finding things tricky but was too ill to even send Christmas greetings on line 0.o

Its swings and round about - but it is at least something and part of my fight back of me living is trying to make this world a better place.

So I am currently a Death Head but do have High Octane blood and hope a little engine over haul will help with things - it's just a little tricky as it has to be left running whilst the maintenance work is being done.

Recap - I feel/felt like I'm dying - probably because I actually was - trying to do more than survive and get myself as well as I can - have traumatised family due to the almost dying bit and not seeing any friends and family (big issue for youngest who needs kids to run around with and has been very lonely) - focus on family emotions rather than on grades or outside assessments. It is the anniversary time for lots of the deaths of people I love this month and also I will probably be hitting people up for sponsorings for charities to help get me fit because my arse is way too big. Also also all grown ups in our household have now been vaccinated first doeses for a few weeks which is an emotion boost even if it scrubbed me out for a week and a half (nothing like actual covid).

Electronics Projects (by )

So, my electronics workbench is a mess.

This is abundantly clear in the picture from my blog post on redesigning my workspace; the awkward layout is certainly part of the problem, but a deeper problem is that I don't do many electronics projects. So this big workbench is rarely used for its intended purpose, and thus accumulates junk, and thus isn't very inviting to start projects at, which adds to the fact that I'm a bit edgy about STARTING electronics projects, and a vicious cycle has set in...

The only electronic projects I did lately were the 12 volt DC power distribution system for the van and a 9:1 impedance transformer, but those were mainly mechanical builds; the electronics were trivial.

Insulating the Workshop Roof (by )

I work from home, in my workshop at the end of the garden. I have my rocket mass heater to warm it in the winter, but while the radiant heat from the primary heat exchanger is comfortable, as soon as the fire burns down it's freezing again, because the room's air temperature doesn't really rise.

Also, in summer, I roast in here; the sun beats straight down on the dark felt roof above, and my ceiling is just four layers of felt and a couple of centimetres of plywood, so on sunny days the wood above me reaches 40-50 degrees Celcius and roasts me with infra-red radiation.

BUT NO MORE!

Because over this past summer, I've finished insulating the roof. I did this by getting inch-thick foil-backed foam boards and fixing them between the joists, with twenty centimetres of woolly insulation above that. Here's a few photos to illustrate what I mean, taken when I tested the method at the end of last year:

Insulation around the chimney

There's a gap of about five centimetres above the woolly stuff, to allow air to flow. A big danger of sealing a roof up with insulation is that warm, humid air from the room beneath will manage to sneak up, past the insulation, reach the cold area above, and promptly condense, making it nasty and dump up there - leading to the roof rotting. So I left an air gap, and made sure that every area of the roof was ventilated. Since the roof is punctuated by wooden beams, this meant putting an air vent at the top and bottom of each "bay". In the summer, the air rising out of the vents at the upper end of the roof was pretty hot, too, so convection of air along the underside of the hot roof also helps to get rid of heat in the summer.

Thankfully, this meant that I wasn't roasted during the summer; and now I've mainly finished running aluminium tape over all the edges, so my warm air doesn't seep up and dissappear, it's also keeping the heat much better in winter. I've been running the rocket mass heater in the mornings and the room temperature has risen and stayed up for most of the day, thanks to the residual heat from the secondary heat exchanger now being enough to replace heat lost to the outside.

Also, it seems the aluminium tape makes a good electrical contact with the aluminium backing on the foam board, so my entire ceiling is a big radio-frequency reflector, which might prove useful in keeping all the noise-leaking computers in my workshop separate from any antennas I put on the roof...

Debugging poor home wifi at the Snell-Pym residence (by )

So, we have a fairly complicated network at home - the Snell-Pym Family Mainframe has a dedicated DSL link with a static IP for hosting various Internet-facing things, as well as providing internal services to the home LAN. The home LAN has the usual mix of desktop computers, the laser printer, and two wireless APs for mobile devices to connect to - one in the house and one in the workshop, because one can't get a good signal to both locations. And there's a separate infrastructure LAN for systems control and monitoring.

Now, we've often had on-and-off poor connectivity on the wifi in the house; this used to happen sporadically, usually for around a day, then just get better. The wifi signal strength would remain good, but packet loss was high (10-20%) so stuff just didn't work very well. TCP is poor at high packet loss; it's OK once a connection is open, but packet loss during the initial SYN/SYNACK/ACK handshake causes it to take a long time to retry on most implementations.

I went looking for interfering networks (we live in a pretty wifi-dense urban area) using an app called "Wifi Analyzer" on my Android phone, and it showed a strange network, always on the same channel as the house wifi (as in, if I changed the channel, it would move too). The network never had a name, and the signal strength was about the same as the house wifi; sometimes a bit stronger, sometimes a bit weaker. Read more »
