Yemen, The Congo
A couple years ago I read a book about the origin of AIDS. It's called The Origin of AIDS. True to form, the book is a straightforward analysis of all the facts, in detail that leads the reader to think about other things. Honestly, a lot of important aspects of the development of the AIDS virus are at first glance pretty tangential. At any rate I'm now reading a book which covers the Belgian colonial period, filling in a large gap of history that The Origin of AIDS left me with. It's called King Leopold's Ghost. I recommend it. Both authors make very incisive points about the personalities and situations in their books, which lend themselves to a deeper understanding of humanity (or lack thereof in some instances).
The twin cities Leopoldville (modern Kinshasa) and Brazzaville were the seat of both the origins of colonial rule in the African interior, as well as the origin of AIDS. Interesting! And not entirely coincidental.
At any rate, these books have made me intensely interested in Africa, a place which I had up to this point written off as a horrible place that I would never visit. I probably still won't visit Africa, but I can at least learn about it with satellite imagery and Google searches.
Google is good, but I found this music on accident. It is excellent but not African. Play this as you look at the rest of the collection I've made below.
It turns out that there is a subculture of "Sapeurs" who dress up in suits in the equitorial heat. Very interesting.
This slum I found in Brazzaville is almost entirely abandoned, its roofing tin having been salvaged leaving husks of former households. Literally hundreds of former households, now empty. I would really love to know why. This is the sort of question the Google cannot answer. I mean, they didn't even street view it. My guesses include outbreak of disease, or perhaps government eviction of squatters.
*Probably due to the fallout from the Second Congo War.

This is a village outside of the main southern town in Yemen. Its intense imagining the lifestyle there. Seriously poor. Maybe it's cool, but I bet it just sucks. View Larger Map
Then there is this stadium, in the middle of nowhere. The parking lot is just desert with a road around it. It is about 45 miles away from the nearest city, in a place where there is obviously plenty of open space right next to the city. It reeks of royal excess but there is not a royal family in Yemen.

Socotra is an island south of Yemen which is actually closer to Somalia. It has really unique wildlife, with heaps of endemics, in a similar fashion to Hawaii. However, it is not volcanic, which means that at some point it was connected to a continental body. This means that Socotra probably started out with significant diversity, which ended up speciating from the mainland flora and fauna. It is beautiful, but I think I'd rather go back to Fiji for diving. Also you can't just go there and explore, as it is ... well I don't know what it is but there aren't rental cars.

Yemen
I eventually panned over to western Africa, and then onto Yemen by accident, as it's really close by. Yemen is interesting for a few reasons:- It's basically a desert, but people live there.
- It is incredibly politically unstable, and there have been numerous civil wars since the early 1990's. Currently the federal government only has control over about 1/3 of the country's territory.
- Apparently the US' eye of Sauron is turning on Yemen due to a resurgence of Islamic extremism. Sometimes I think they deserve each other. Blech what a mess.
- There is some strange shit you can see in the satellite imagery, discussed below.

Australian Retail
Wait wait, I found it for $20 (before shipping) on an online AU hobby shop. But the point stands. Expect to pay 2~3x the US price for things in AU.
I want it to router out my skateboard for weight savings.
Street Views Germany
So Google Street Views did manage to map some of Germany before giving up due to NIMBY concerns. Look at this country house. So nice.

Samsung WDJ1555C Repair
we use cloth diapers so the washing machine is really essential. A while ago it started hesitating at low speed under heavy/wet load. I thought the belt was loose, so I tightened it, but the problem persisted. I noticed that the motor was not spinning, but instead just jerking and hesitating. It is hard to tell this though, as all parts are black - so I put a small piece of yellow tape on the small pulley and watched it not go.
A view of the main PCB (power control board?) which I believe is the actual point of failure. Electric motors require the most electric current when they stall (see here) so I suspect that this is a current delivery issue. Since it wasn't the motor, I bet it is this. One of the capacitors looks kinda puffed out. This part (MFS-AUJ2RC-00) is AU $200. Note that the parts list linked to above mislabels this PCB as MFS-AUJ2RC-S0, which is actually the front control unit with the spinning control knob. I checked the label on the actual part and this main board is definitely MFS-AUJ2RC-00. I'll order it next week I guess.
Brief motor swap steps:
- Get behind the washer with at least 1 m of space from the wall.
- Unplug the washer.
- Unscrew the 4 phillips head screws holding the rear panel on. This rear panel is just grey sheet metal with a wiring diagram on it.
- Set the panel aside.
- With a 13mm socket and extension, loosen the bolt which is obviously holding the motor in place, just to the right of the small pulley. Completely remove this bolt. There is a plate-nut that it goes through which should stay in place once you remove the bolt. (You can kinda see this nut plate in the photo below, near dead centre of the pic far below). Only one bolt holds this motor on.
- To loosen the belt, squeeze the two sides of the belt together.
- Slide the belt off of the very large pulley just using your fingers. It doesn't loosen to the point where it comes off on it's own - a little force is required.
- Push the motor down gently until it swings away from the previously bolted area.
- Slide the motor towards you (out towards the back) about 2.5 cm and it will fall off of the two plastic studs which hinge it to the drum. It is heavy ~7 kg so be ready for this.
- Finagle the motor out of the back of the washer and disconnect the wire harnesses and ground strap. Note that you shouldn't pull on the wires, only put force on the plastic plug ends. A small screwdriver is needed to gently push the larger plug prongs out from the back, then wiggle time.
- To reinstall, the only tricky bits are:
- There are two plastic "caps" which adapt the holes on the motor to the smaller plastic studs which they slide onto. These caps should be either on the studs, or in the mount holes when you go to put it in.
- Getting the belt back on the pulley is tight. You will need to "walk it on" by first putting the loose belt around the small pulley (about half way out on it), then place what you can of the belt onto the large pulley. To get the rest of it on, manually rotate the drum (towards the part of the pulley which is not yet mounted) using the large pulley spokes as handles. Don't worry too much about damaging the belt - they are tough. But if it takes a lot of effort, the motor probably isn't pressed into the right swivel position. Try pushing the motor up to relieve tension and try again.
- Lining up the 13 mm bolt with the nut plate hole is hard. Take a few tries, swivelling the motor just a bit and try again, threading it by hand till you feel the threads bite and go in a bit (1 turn if you're lucky).
- Tension the belt by prying with a screwdriver until it gives a nice "twang" sound when plucked (quality beats quantity they say), then tension the 13 mm bolt fully. It doesn't take much torque, but seems hard to break too so you'll be right.
UPDATE: This machine was sold to us as "new but damaged in transit" seconds. What they didn't tell us is that it had a refurbished brain in it, which had been damaged by a careless repairman. So it was used. Australian business ethics standards are a bit low. The brain was bad, and the gel that the main PCB is embedded in had been damaged by the repair. A new brain (MFS-AUJ2RC-00) fixed this washer. It has 15 unique plugs (!) which you will need to reattach. If you want to borrow a working motor to see if that is your problem, get in touch via the comments and you can use my leftover one. If you can prove you have kids and use cloth diapers, I'll give it to you.

Denmark
Wow Denmark. Very neat. Even the piles of dirt I found were very neat.

Australia is sloppier, less particular, more rugged.
