No photo again but today's work didn't merit it. Two things were achieved but only two.
Those that can cast themselves back a couple of blog entries will recall that I ran out of rivets putting the steel plates over the sites of the old schoolbus flashers. Well, today despite feeling quite yucky from working, I replaced the four screws used temporarily with rivets then sprayed over with grey paint. Not very exciting but worthwhile.
My other accomplishment or rather the reason I consider myself to be the world's biggest sucker stems from an experiment I carried out today. Those with very long memories will recall I bought a pair of electromagnets from China some months ago. It has already been established that no matter what polarity current was supplied to it (which would normally alter electromagnetic polarity), the electromagnet never would change polarity. In fact, it seemed to be both polarities simultaneously. Two identical electromagnets would not repel each other. They would just attract. Similarly no matter which polarity of permanent magnet was introduced to the electromagnet, the electromagnet could never be persuaded to repel the permanent magnet. Pretty strange and rather useless.
Today I tried the electromagnet for its attractive purposes. Fail again! It would attract but as a 9v magnet, it would attract from around 1/8 inch but very feebly. It would grip something strongly but was utterly useless in all other respects.
My goal is to engineer a way of opening the bus front door. What I'm trying to do is to lift the locking latch on the front door opening mechanism. Carpenter did employ an electric door opener but my bus has only a manual opener. Had I had the electric version, I could have simply tapped into the circuit with a remote opener. Looking around those would set me back $500. That's just too costly!
Clearly I was a fool to believe any Chinese electronic gizmo would actually work. I do buy bits from China but that was my first electronic gizmo. Oh well, lesson learned. Don't buy any electronics from China.
Looking around, there are some linear actuators on sale. That would make the door an electric only affair. That would make exit in an emergency somewhat interesting so I'd have to put some way of bypassing the electrical system. Sounds interesting though!
Motorhome self build project. Built and designed by one person over the course of about 36 months. The base is a 1994 Carpenter school bus. The end result will be a low energy consumption motorhome.

A rainy day
I blundered today. When I went out to the bus, it was dry. While I was inside, it began to rain. I had hoped to derust the other side of my steel plates then to paint them ready for welding tomorrow since tomorrow is alleged to be going to be a dry day. We all know the weather forecasters speak with forked tongues though!
While I was in the bus, I sat down and completed my second 20A cable. The one terminates in a NEMA 6-30R which will plug straight into the NEMA 6-30C when the battery compartment is completed. Construction in failing light was not easy but was completed fairly swiftly. I have to say it doesn't look at all bad. It was confusing that the hot/cold pins had no markings other than X and Y which meant I had to look it up to see which wire should go where. I'll doubtless get the same issue when I wire the NEMA 6-30C.

Meanwhile, since the lottery is now up to $900,000,000, m'lady wanted a ticket so I headed to the store and bought two tickets. I don't so much believe I stand a chance of winning but I'd love to see somebody win $1,000,000,000 and be a billionairre for a day - before the IRS takes 50% and the state takes their 20%, leaving them with probably $400,000,000. It'd be hard but I'm sure that by economising they could just about live on that money! For myself, I"d be happy with any amount
When I went out I planned to stop off at a place where barrels were on sale. Oops... I was in thick traffic and missed the turning so I carried on to Lowes (hiss, spit). There, I realised I'd forgotten the piece of tubing I'd cut to take to Lowes for sizing! Still, I had a look at various plumbing bits. Then I looked at hooks from which I could hang my bucket. Looking at them, they would have had a difficult job coping with the lip inside the skirt on the bus. I passed on buying a hook. That was fortunate as it so happened.
On the way back home, I passed the sign where used barrels were on offer. The actual place was a long way down a lane. Down the end of the lane was a downtrodden looking mobile home. In the yard, a big dog barked noisily while some 15 gallon barrels stood to attention. The fellow must have seen me arrive and opened the door as I approached. He was very pleasant and didn't have change for my $20 so rather then buying two of his $8 apiece 15 gallon drums, I bought 3 with my $24. They had contained some kind of brownish liquid wax. That was slopping about inside the drums so I made very sure the caps were screwed on firmly in order to avoid spills. Clearly the fellow worked where such barrels were used. I'm very happy with my barrels. I suppose I could put 3 grey water tanks or two grey and a black just in case I decide to put a flush toilet some day.

30 or 45 gallons of waste water is a very attractive idea because that puts me squarely into boondocking territory. I can carry fresh water in jerry cans and to be honest the risk of tampering with fresh water supplies accessible from the outside is low but nice not to have. Indeed, with the waste water, a faucet could empty that into a bucket or a hosepipe.
Looking around the bus today, I noticed a tag from a conversion company. I've never noticed it before but it looks like it was Tennessee hillbillies that did the conversion. Clearly some kind of professional hillbilly conversion.

Now that I have the barrels, all kinds of possibilities open up for plumbing. Of course, the things I would have liked to have done didn't get done. The path is there to go way better than just a bucket.

An electrifying decision!
Again, it was another exhausting day down the salt mines. So much so that after work I didn't even glance at my bus. I'm so glad I did so much over the summer!
Remaining are some minor things inside the bus that I can take care of this weekend plus the electrics and plumbing. As far as plumbing goes, dealing with waste water is easy - gravity takes it down to a tank I'll place under the bus (or a series of tanks, even).
As far as electrics go, I've been mulling over all the options. Those considered so far.
1. Plug the bus into a campsite power supply and have 4x120v sockets. No water heater, no electric pumps. This is by far the cheapest option.
2. Put a generator with the plugin option. Downside, diesel generators start at $2,000. Gasoline generators start at $100 but to get one big enough to power my microwave or kettle, its $300.
3. Put a wind generator. This is an interesting, off the wall option. It seems wind generators generally have a poor reputation at small sizes and low altitudes. That's without mentioning they start at around $300 for something that's just an electric motor with a fan blade attached.
4. Use batteries. There's quite some disagreement about how many are needed. One person will swear that my microwave will set the batteries on fire while somebody else claims to have done it with no problems. And batteries start at $80 apiece.
The general route map I've worked out is this...
1. Go for option 1 initially.
2. Slowly build up toward option 4 with plenty full load testing. During this phase, batteries will be charged while plugged in .
3. Investigate solar and wind options.
4. Investigate generator options.
The problem with solar is flexible solar panels are around $189 for 100w. Wind is a different problem altogether that I have not fully researched. It's looking as though the available wind turbines just aren't that great. But a 100w panel would charge a 100ah battery in 12 hours of full sunlight. This means that with partial sun I'd need 2 or 3 panels per battery. Assuming 4 batteries would be fine, that's 10 panels at $189 each for a grand total of $1890. That would pay for a $300 gasoline generator and 700 gallons of gasoline to power it!
Given that I'm unlikely to be boondocking that much, solar power seems just a little wasteful. Wind power looks more promising especially since the wind also blows at night. Backed by the $100 generator, that might be an acceptable solution. As far as I can tell, solar just seems to be somewhat of a scam. It works but it's uneconomical and the greens have scammed everybody into thinking its viable when honest cost analysis says its not.
Wind has three options. The first is a vertical axis turbine that I raise on a pole after parking. The second is a horizontal axis turbine that I raise on a pole after parking. The third is an array of plastic tubing on the roof as a wind collector, channelling the wind down plastic tubing to a smaller, more powerful turbine underneath the bus.
