My first shower

Yes - I'm a dirty bugger - this is my first shower ever. M'lady's water heater died yesterday so there was no hot water last night. Thus, this morning I went to the bus to get my shower equipment. I could have showered in the bus but as the shower base is being used to store screws etc, I didn't venture use the shower in the bus. Mind, I also need to install a shower curtain.

The good - I had a shower and managed to wash my hair, my body and came out clean. 

The bad - the shower unit is new (only been used once for testing) yet the hinge on the battery compartment has broken already. The hose connection from the pump unit to the output hose leaks pretty well.
  
I wasn't really expecting to have to fix the shower unit on its first real use. Thank goodness I didn't pay Amazon's rip-off price for it. I paid $18 rather than $35 because I bought mine on eBay. Same exact thing that Amazon charges more for. Having said that, duct tape is cheap and fixed the problem. I think a more permanent solution will be to put an external battery compartment.

It doesn't look elegant but it works which is the main thing. For the leaky hose connection, I suspect duct tape might not be the best answer. It's too flimsy to crimp the hose too tightly so I suspect the best would be to use a piece of soft copper wire and twist it slowly until it's barely tight. There might always be a leak there.

To use the shower, I half-filled my 3 gallon cooler with cold water then put a kettle full of boiling water into it. The result was luke warm - I could definitely do with two kettles of water. Having said that, I did manage to shower quite successfully. The key to good flow seems to be to mnake very sure there are no kinks in the hose. It definitely performed better today - with far more power than when I first tested my shower unit.

Showering like this definitely takes a while as it needs time to boil a kettle of water. The cooker works very well and the floor underneath does not heat much. I'd say the heat transfer is about on a par with the heat from my microwave.

The Coleman cooker cost me $18 from Walmart and the gas cannisters are $3 each. That's really not bad at all. The shower unit was $18 too. 

In terms of use, I used about a gallon and a half of water to shower. My hair is long and takes a while to shower. The key is to wet it, rub shampoo in quickly then work on rinsing it out before proceding to lower parts. Crouching in the shower worked well. Now if I was some bald dude then I can well imagine using maybe a gallon or less of water. I'm not a bald dude though!

I can honestly say that I really quite like this shower setup. I had thought it might be irksome or problematic but it all went together very nicely. The biggest improvement would be for the pump unit and the battery unit to be separated. Now I have seen some 12v versions of this which would work well enough if I had 12v in the bus. Right now, my unit runs off 4 D cells. 

In conclusion, the shower unit's construction quality leaves something to be desired. The efficacy is good. The cooler worked very well and works as a very handy limiter on the amount of water used. The gas cooker was slow and the kettle didn't hold enough water. The shower I had was very effective and quite pleasant though luke warm due to my cooking up only one kettle of water. The cooker needs some while to cool before being put in its box again. I can't imagine lugging the shower and the cooker if I was actually on a backpacking camping expedition but I suppose somebody woud. The nearest alternative is a gas-powered shower unit that costs $140 or over $100 more. This setup represents very good value and I'll keep using it.

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.
