Is this the end?


It certainly looks like the end of the road for my cheap Walmart microwave. I count 5 bullet holes in its carcass. Seriously, how can Walmart sell junk like this? After a little over 2 years use the bottom of the microwave inside was very rusty. It lay idle in a dry location for a further 2 years then when I set to cleaning it up, the pan had holes in it under the paint. No wonder every time I cooked, the countertop was covered in nasty looking water.

Today was one of those days when little was accomplished. Mostly that was because I am not really all that well. I didn't go to Lowes (hurrah). I did trim a little of the excess steel from the fridge to make some blanks to cover the apertures under the top front flashers. I started that a little late in the day and despite a spectacular mishap that went to show why only fools would take the guard off an angle grinder, I managed to cut two rectangles of steel.

Once I'd cut the steel, I ground the rusty bits back to clean steel then sprayed both sides with zinc paint. The zinc spray can started dripping and dribbling paint which was annoying but on the other hand this is exctly why I do prefer a brush and pot of paint. There's just no point in wasting a 65c brush for a little bit of painting though. Spray cans are handy for quick, small touch ups and that's about it. I decided on rectangles on the basis that they're easier and faster to cut. As long as they're mounted in the right places, they should have a balanced look. I'll have to trim the top outer corners to match the curve of the roof and I'll have to trim and indentation for the CB aerial. Other than that, the steel should be fine as it is.

As the paint was drying I turned my mind to the rear turn signals and switched one of the lenses over so that unlike the right turn signal, the left now has no arrow. It didn't improve matters. I suspect the bulb could be the problem in the left turn signal. It just seems dimmer than the right turn signal.

By the way, the right turn signal is a completely new unit that I installed last year as is the right hand reversing light. I'll have to replace the bulb to see if it improves matters. Really and truly it doesn't matter to me whether the lens has an arrow on it or not. I just hoped I could make it brighter. So, it looks like a new bulb but I won't stop there. I'll see if I can get some of that silver reflective Christmas wrapping plastic foil and fit it inside each of the light assemblies to improve the amount of light coming from them. These things just aren't visible enough for my liking in daylight.

By the time the light began to go, the paint on my steel plates was not fully dry so I put them inside the bus. I would have liked to have installed them today rather than leaving tape over one of the apertures. Having said that, there's always next weekend and the tape should keep rain out.

I looked at the ground beside the bus. That'll need a good clean up when I finish working on the bus. I have a feeling I'll spend an afternoon picking up trash from the yard! The plan for the big piece of fridge is to cover the lower door window aperture at the back of the bus. I'll have one piece that I'll trim to weld into the aperture. Once that's welded, I'll fill the space behind it with closed cell insulating foam then either use rivnuts and screw a sheet of steel over the inside of the door or rivet a sheet of steel there. On the whole, I think rivnuts make more sense as it allows me to perform maintainance if needed. I just hope I can make my welds waterproof.

I am very disappointed with the amount done today. I know I have overdone it today. I know I overdid it yesterday too. I wanted to go to Lowes to get my final plumbing part. I wanted to put two stop nuts on each bolt for each barrel. I wanted to plumb the shower barrel in fully. I'm still looking at plumbing the handbasin. I just hope I can get everything completed by the end of the month. My dad was griping that I hadn't completed it by April of last year, which was my original completion goal! I think my original target was a little ambitious given that I had so much to learn and that I'm such a perfectionist.

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.
