Ouch! My sore arse...

Now I know what a gay man feels like! My arse is still very tender after sliding down those stairs the other day. Indeed, it's now a nice shade of purple. I did wonder how close to the purple of the galley area of the bus it is but it would be hard to color match and I'd have to get somebody else to hold up the color matching cards. I don't think the world is quite ready to see my bare arse!

Today I fully intended to get to work on the coil for the front door unlocking system but as soon as I got to the thing, the glue had failed where I'd glued the enamel wire to the brass tube. That was addressed by cleaning the glue off the tube and the wire then wrapping aroud and spraying with varnish. That should hold it. If not then I'll have to go back to taping it.

Meanwhile, those with longer memories will recall my bathroom vanity. I'd cut a hole in some wood to make the original kitchen fixture back around January and then subsequently recycled the wood when I built the current vanity to include the original handbasin that came with the bus. As that handbasin totally lacked any means of securing it to the vanity and as it also had two large holes for water piping that I coudn't easily fill, I removed it and replaced it with a piece of OSB cut to size.

Today - even though it was pouring with rain, I took that OSB to one of the abandoned sheds on m'lady's land and sprayed it white. The paint dried to touch dry astonishingly quickly given that it was - as I said - pouring with rain. 

Having sprayed both sides, I took the OSB to the bus and set it in place. I'll screw it down tomorrow. It had been dark, rainy and overcast all day so by the time it was dry enough to put in place, it was already dark.

The plan is to stand a jug and a bowl on the vanity top. Think back to the Gary Cooper westerns where in the hotels there was a chamber pot in the room and a bowl with a jug for washing. This setup gives me so much more flexibility because after washing I can just open the emergency exit door (conveniently situated to the left of the toilet) and simply chuck the water out. In more regulated climes, I can empty it into the bucket underneath the vanity ready to empty at leisure. Now the downside of this arrangement is that unlike an ordinary handbasin, I now have nothing that doubles as a urinal unless I use the shower. Fortunately I do have my bucket and I suppose that could double though it'd have to be scrubbed every time it was emptied or it'd begin to smell. On the other hand since Walmart buckets are $2.50 and the lids $2, it's no hardship to treat myself to a new one every now and then.

Thinking about the front door unlocking mechanism, if the current electro magnet idea doesn't work then I might work on some kind of cam mechanism and an electric motor. That stands a reasonable chance of success though it would have to be designed such that it doesn't remain in the unlocked position.

When the rain finally stops, I'll be able continue with construction on my battery compartment. That will first require the battery compartment floor components to be derusted, painted and welded into the compartment. Then I'll paint the whole compartment. The sides will be thinner and riveted in place after the whole thing has been welded underneath the bus.

I realised I should try to get the bus retitled as soon as possible. I need to get the plumbing under the bus completed which will basically be a downpipe going to a U bend then down to a tap that I can close when I don't want to let water out. Being closable also means it's a way of keeping critters out.

Cooking is an interesting thing. For cooking, the answer could be electric, gas or tea-lights. I've been reading about cooking using tea lights and how many preppers use tea lights for their cooking needs. I already know how to blanch almonds using a candle and a spoon but this is more interesting. I like the idea of using tea lights as the worst that can happen handling a tea light is that it melts in the heat or bounces on the floor when dropped. Unlike liquids or gasses, they're much more controllable. They also keep almost forever and the biggest thing of all - they're pretty darned cheap. Now the downside is soot but as I was already going to have to install some kind of exhaust vent, it shouldn't be a great problem.

Thinking about exhaust vents, I could put one at the top of the window I filled in or I could make a hole through both layers of the roof. On the whole, I suspect they both have the same number of problems. The biggest will be leakage and then insulation. I don't think welding will be a good solution for the vent. 

Purple Heart? #nissan #baddesign

I was injured in action both today and yesterday hence its unlikely there'll be much done on the bus tomorrow.

Yesterday I was unloading my Xterra when I encountered the second of two disastrous design errors Nissan made. The two hydraulic arms that cost $80 each and hold the tailgate open had broken. This is the most assinine design ever as hydraulics always break. Then to imagine they'll last more than the warranty period! Those things broke straight after the warranty expired on them. That leaves the tailgate as a disaster waiting to happen.

Needless to say, that disaster happened yesterday when I encountered the second of Nissan's disastrous design decisions. The corner on the door is deadly. That, I can assure you, is really painful when you run into it with your head. Imagine standing underneath it when the hydraulics break - that could be deadly.

There really should be a class action against Nissan for this stupid piece of design. You can see clearly how dangerous that corner is. In my opinion, there is no finer tailgate than one that splits in the middle and opens to each side.

Today's accident involved slipping on wet stairs in the rain and sliding down the stairs to the ground. Quite a bumpy journey that left me covered in bruises. Fortunately I won't miss any paid work this week but I will miss my voluntary job. I'll also suffer yet more delays in working on the bus.

One of "those" days *sigh*

Today was a day when nothing went quite right. I woke with a headache which is never a good portent of things to come. After a leisurely breakfast of yet more Xmas dinner leftovers, I went outside and noticed the sky was overcast. Clearly no welding today because the instructions on the welder say do not use in rain and rain was forecast.

The steel I cut yesterday has bright orange rust spots on the freshly cut edges. That's not welcome but not unexpected. I didn't treat the edges as they'll have to be welded anyway. The rest of the steel is fairly rusty so I'll have to sugar blast the whole lot to clear the rust. Then I'll have to paint it with rust killing paint then scrape the areas to be welded and weld it all together then put yet more anti-rust paint and then a topcoat. I did, however, remeasure what I'd cut and aside from probably having to trim corners to fit around bolt heads, it's pretty much the right size.

Next I looked at the schoolbus flashers. I need  to switch the amber and red around so the ambers are on the outside. That was something I could do relatively easily so I hopped up on the hood and started undoing screws for it was a simple matter of switching the lenses around. Wouldn't you just know it! One of the screws refused to budge and the cross head became a cone. I'll probably have to drill it out now. At that point I said that given the way I was feeling, it wasn't sensible to proceed and packed up for the day.

I looked at my old red LED sign that had been broken in my car. The actual sign still worked but the mounting was broken. As I need a car cigarette lighter plug, I cut the cable off and tossed the sign in the trash. It was sad to see the sign go but it had paid for itself and I'd had a couple of years use out of it. I used to put that sign in the back window of my car and rent it out on fiverr.com as advertising space. People would pay $5 to fiverr to advertise their product for a week and I'd get $4 of that in my Fiverr account. After a very, very long time I amassed enough to deposit in my bank account and by the time they had charged me a fee to deposit into Paypal and Paypal had charged a fee to deposit in my bank account the money was even less and I figured given the time and the chargers on charges on charges, it wasn't worthwhile. So, yes - to the people who ask - I did make money from Fiverr but in the end it works out at about $2.50 per hour so it's really not worth the effort.

I checked out my solar panel and connected it to an electro magnet which then failed to pick up anything despite the panel voltage being around 16.7 volts. I'm really not that impressed with this solar stuff, to be honest. It all sounds phenomenal - I mean - who doesn't like the sound of free electricity? The reality is somwhat less than satisfactory. As an experiment a few years ago, I connected a powered off mobile phone to a panel and left it on a windowsill, facing the sun, for a week. At the end of that week, I powered up the phone and while there certainly was power there was only enough for about 15 minutes usage. I'm going to plug on with solar but I'm not going to be fool enough to believe that it's going to be majorly worthwhile. It might - if I covered the roof with panels - charge my phone every day but I doubt that it'll do anything more than that. Indeed,  as I said before - the amount of money spent on solar panels to charge batteries would pay for a generator and a whole load of gasoline which would charge the batteries in a fraction of the time, day or night.

My solar panel - for those who're interested is allegedly 12v at 5A. I have yet to see it do anything bar make a tiny light bulb glow very dimly when exposed to direct sunlight. My idea had been to connect the panel via my ciagrette-lighter socket in the cab to the battery to allow it to keep my battery topped up. I fear that the LED on the cigarette lighter socket might use more power than the panel can supply in a day!

The electro magnet I started the other day still needs to be completed. I'll have another go at that another day. I'm not feeling that glowing positive feeling at the moment what with the cloudy weather and the absence of success. This wonderful two weeks off for Christmas has turned largely into two weeks confined to the house due to the weather. Still, I have another week left - there's a huge oppotunity there for the weather to change its mind and give me glorious sunshine and dry days.

Out of curiosity I put the meter on the lighter socket and got 12.3 volts. Clearly something amiss there. The voltage should be higher - something in the region of 13.8v given that the batteries were charged a week ago. There could be some form of resistor or zener diode in the lighter socket, limiting the voltage to 12.3v. It's good to know! I suspected putting a solar panel on as a battery mainatiner wasn't going to be simple. Nothing ever is which is why though I was all in favor of an all electric bus I'm beginning to veer towards as little onboard electrics as possible. Indeed, I might even rethink this battery compartment and possibly just have a compartment for the main breaker box. That'll be a load lighter and smaller. It also means I can rivet most of that silly hillbilly cable compartment door shut and just use part of it as an access panel to my breaker box.

Thinking more about batteries, I discovered a source for C size NiMh cells. There seem to be people putting them together in blocks of 10 to produce 12v batteries with 10,000mah (or 10Ah). There seems to be something called a DC-DC converter which takes whatever voltage and outputs at a constant voltage. Thus, as the power in a battery declines its voltage will drop. The DC-DC converter maintains the voltage at a constant level, presumably at the cost of amperage. That answers my questions about how supercaps can be used. As their power level drops, so too does their voltage.

Given the low amount of power I need, given that I'm really only charging my phone, my $50 tablet and a $20 mifi pad, I'm really wondering what kind of power storage to use. Realistically, I probably don't even need a battery compartment for that amount of battery power! Still, I'll plug on because I might want to expand later.

Another epiphany

Toda started with the usual tummyache after eating too much on Christmas day. Then I headed outside to do battle with the metal that I dragged out of the bushes a few days ago that looked like an ideal floor for my battery compartment.

Cutting thin metal is always a challege for my angle grinder - which is now working perfectly thanks to the new carbon brushes and I went through several grinding disks. Good job I bought a second 10 pack of disks a while ago! Just look at the state of the disk I've just been using.

I cut the steel construction I found a few days ago, cutting the edge off one side and cutting it in two such that when two edges are welded together, the construction will be approx 18" by 29" which is about the size of my battery compartment.

As the steel had some handy folded edges, these will act as a strengthening bar down the center of the compartment. Very useful. I had, however to trim the excess fold off as it is somewhere water is likely to collect.

While cutting the floor of the battery compartment, a thought came to mind that has occurred before - namely why I'm even putting a battery compartment. I definitely need access to my main breaker panel and that's always best under the bus. Other than that, I can store the cables more securely inside the bus.

Given that I'm not putting a big house battery, the point of a battery compartment is somewhat questionable. Having said that, it does set me up for future expansion.

Thinking about batteries I was wondering about using NiMh batteries rather than lead-acid or lithium. Lithium batteries are just horribly expensive. NiMh batteries just don't seem to be available in 12v. This is a bit annoying! Out of interest, I looked up NiMh AA batteries and found I could get 48 for $24 and 3,000mah each. If they were put in sets of 10, giving 12v per set then I'd get 4 sets at 12,000mah or 12Aah. 

Thinking further about the NiMh idea, 6v would be way easier to work with just 4 batteries put in series. The downside is that all the charge controllers are set up to charge lead-acid or lithium batteries. To my mind, NiMh is way better than lead-acid because it doesn't gas and can be completely discharged without harming the battery.

Given that the only power I'd need would be to charge my phone, tablet and batteries for my LED lantern and my shower pump, I could probably get away with just D cells and a solar D cell charger. The D cells could in turn power a USB charger. Heaven knows how long that would take to recharge my phone though.

There are a whole load of different options out there for power. My favorite for cooling and for refrigeration at the moment are fans powered solely by solar power and a fridge powered solely by solar. The cold could be maintained in a fridge by simply using freezer blocks. The fans need only to remove heat when the sun is shining. As for the rest, lighting, the shower pump and phone charging - these can all be done from NiMh D cells. For the moment though, I shall continue the plan to install the battery compartment and the shower outflow.

Meanwhile, in a stunning development, the bathtub that m'lady often complained about has vanished. It didn't so much vanish in a puff of smoke but more behind a garden tractor and was hauled to one of the junk piles in the back yard.

It certainly looks better without the bathtub. For those with long memories and the ability to hunt through this blog, the bathtub came out of the original construction. It was used for most of the last year as a handy trash recepticle and had it not been full of trash, would have been easy just to carry.

Things are definitely progressing. The last thing done today was to paint the underside of the new bathroom vanity. This vanity will not have a sink. Instead it will have a removable plastic bowl that can be emptied either into a bucket or down the shower and hence into the bucket under the shower or onto the ground.
Apparently emptying water that's been used for hand washing is frowned upon. That seems to be just plain bizarre to me but I suppose if dumping grey water was approved, people would stretch it further and dump sewage too. Honestly though, as long as its buried properly even sewage can be disposed of outdoors without harm to the environment.

problems, problems, problems

It's one of those days. It started with a return of my stomach virus which wasn't entirely welcome but not unexpected. I don't expect to be fully well again until probably March. I work with children and they're extremely generous with their virusses.

Today's only activity was to complete the 20A cable I started to construct last night. At 30 feet it turns out to be a bit on the short side. I'd thought 20 feet would have been plenty but I need more. I"ll probably get another 30 feet of cable after Christmas. For the moment, what I have will suffice to complete my welding. Welding will, of course, have to be done on a dry day. That's not today.

Meanwhile, the blogging application I used on my Nexus won't install on my RCA tablet and the application I used for the last few posts decided when the tablet went to sleep to delete the entry I had just typed. Clearly local auto save was not a feature built in! Thus, I'm using the blogger web interface and lots of data.

In other news, mentioning my stomach virus to a friend elicited the response that as I've been ill so frequently over the last couple of months, why didn't I see the doctor. The aswer is simple - I have only a part time job that doesn't pay enough to pay rent or buy health insurance. Ineed, if it were not for the generosity of my lady, I'd have nowhere to live other than on the street in my as yet unfinished bus conversion. Every penny I have that does not go on fuel to get to work, goes on the conversion. This is why progress is so slow. I just can't do it that fast when I can spend only $100 a month.

The more right wing amongst my readers will ask why I don't simply get a second part time job or get a full time job. That's harder than you might imagine. Over the past 12 months my applicaions have yielded one single interview. That was with a local college and the interviewer asked for a bribe. Now aside from the fact I can barely afford to live, let alone pay bribes, a company that has employees that routinely ask for bribes doesn't sound like employment that's going to last more than a day or two after they figure out that I'm not going to pay them a percentage out of every paycheck. A second part time job isn't going to work because where I work is so far from any centers - that's in the rare instance that "open availability" isn't demanded. Open availability means one has to be available 24x7 at the drop of a hat for part time work. Basically being unable to work for anybody else! Yes - employers really do that and its very common.

So, right now, I'm just plain stuck. It seems to me that applying for jobs doesn't work in the vast majority of cases. Those interviewed usually seem to know somebody in the upper etchelons of the organisation and I've always kept myself to myself.

Last year, I got a few interviews but several were cancelled as soon as they discovered my gender or race was not to their liking. I had no idea  that gender or race had any impact on administrative work! Surely ability to do work is far more important than gender or skin color? This year, I can add bribary to the list. Things really aren't looking too good for South Carolina employers - racist, sexist, demanding bribes and God alone knows what next!

Recovering slightly from my stomach bug, I headed to the bus to discover the brass tube that I bought yesterday was an ideal fit for my latest magnet. I glued some magnet wire to the end of the tube in order that it doesn't slip while I'm winding the coil. I'll probably do 12 layers of coils and see what happens. No particular reason why I'm doing 12. It just sounds like a good number.

Rainy day at the Chicken Ranch!

No - not that kind of chicken ranch - the kind that actually has chickens that lay eggs! It's pouring down rain like there's no tomorrow. Indeed, after my hot shower this morning, I've had several cold showers since that made my hot shower seem somewhat arid in comparison.

Being a rainy day, I went shopping after my voluntary work this morning. Stopping off in a few places, I found that the Geek Squad won't work on tablets. I was, fortunately, referred to The SmartPhone Medic. Arriving there I found that they couldn't tell me anything because the boss was away. That begged the question as to why the place was even open and staffed since the staff seem so purposeless.

The next stop was *spit* Lowes where I got some copper tubing to make the base for the coil for my magnet. While there, I looked at the price of cables. $1.15 per foot for 20A and $1.89 per foot for 30A. Needless to say, since I want to set up for both 20A and 30A I bought 20A cable. Now, I don't really see a true requirement for 30A though internally the bus is wired for 50A. I figure a microwave will draw 10-12 amps and a fridge - if I install one - will draw 2-7A.  That's 19A and I can always unplug something if I need to use more amperage. Now I bought 30 feet of 20A cable. That worked out at $34.50 whereas a 30A cable the same length would have been $56.70 - that's appreciably more. I also got a 20A double pole breaker just so I won't accidentally overload the cable if I end up plugging into a 100A, 50A or 30A supply. 30 feet should do for most things. If I need longer cable then 20A is going to save me a bundle. Ready made 20A cable of 25 feet was $80 which I thought excessive! Admittedly I had to buy a 15A plug and 15A socket so theoretically I'll be overloading them. The truth is though that they're made the same as a 20A but with the live pin angled differently. I needed 20A cable in order to supply the welder. If I need more cable - say another 30 feet then the savings with 20A over 30A are much larger.

The general plan is to be able to use 20A and 30A. That's way off in the future though. Right now the plan is to get the bus operational as a motorhome. There's welding to do but that'll have to wait until a dry day. Putting the cable together is a breeze that can be done in approximately 20 minutes. Initially I'll put a 15A socket on one end but after I've got everything done, I'll switch that to one of my Nema 5-30/6-30 connectors.

The big battle is to get things done enough that the bus is operational. Then I can get it retitled as a motor home. Speaking of retitling, today I took advantage of the deluge to visit the DMV to get the retitling papers. As I suspected, nobody wanted to get wet so I popped in to ask which forms I needed. The reeptionist pointed to a seat and told me somebody would be out to help and within a minute or so, a very helpful lady arrived, asked what I needed, zoomed off and returned with some papers. It was all very civilised and very quick.

Once I have the cable/battery compartment completed and a battery installed powering USB and 12V devices, I"ll be ready to retitle. There'll be a lot of tidying and rearranging to be done inside plus installation of roller blinds or drapes as well as the shower curtains but it's all getting tantalisingly close!

Small achievements building toward success

That's the way to do it! Today of note were several achievements in an otherwise dismal, dreary, wet day. I'd like to be able to claim major success but I didn't do anything major. The major stuff all accomplishes itself as it's all reliant upon the small but insignificant steps.

The first thing I did was to make a coil out of some wire, put my new permanent magnet inside and run 6v from 4 D cells through it. The magnet did twitch. Clearly I need to find some copper tubing slightly larger than the magnet in order to wind enamel wire around it. That should allow the magnet to slide easily and should give years of use. I just have to wind the appropriate number of coils around it.

The next success was more basic and less exciting though vital. I tried my old angle grinder without success. Banging it I could get a few spins from the motor before it stopped. I had a brainwave and changed the other carbon brush. I"d already changed one because it was broken. Voila! The thing worked when I plugged it in. Clearly that problem has been solved for the moment. The other one has a problem based around a loose connection. When I need it, I'll tighten that connector.

Lastly, I hunted around in the bushes on m'lady's 4 acres and found a nice piece of steel. It needs some de-rusting but cut with the angle grinder and welded, It;ll make an excellent bottom for my battery compartment. Unlike the hillbillies, I'll drill holes for water drainage. I'll also see about putting a lip over the door to stop water penetration.

The final solution to the power and cooking problem is, unfortunately, going to have to be a gas cooker where the microwave is currently situated. The microwave is rusted and beyond salvation. I"ll have to install an extraction fan - probably a 12v fan running off my small battery. I could run that through the window I blocked up or put a roof vent. On the whole, the window seems more accessible. I thought long and hard about other solutions but this seems to be the only one that makes financial sense. To spend $3,500 on lithium batteries, $300 on a generator or $500 on lead acid batteries to run the microwave or $40 on a gas cooker. That's $10 cheaper than buying a replacement microwave. The big bonus is because I've already done the electrical work, I can still use electrical appliances when plugged in. There's also nothing to say I cannot later just remove the gas cooker and install solar arrays, generators and solar panels.
