Everything I own is packed onto that scooter. One of my T-shirts has been bungied to the tripod on the back to dry it out after some last minute washing. The amazing thing is how much you can carry on a scooter by sticking a large duffle bag between your legs on the floorboard. So anyway, about the gear...
Let's talk about the mistakes first. I took jeans, combat trousers, two long-sleeve shirts, a belt and covered shoes. None of which I used but contributed to a substantial heft. People talk about the mountains getting cold. That's because they're used to 34C. For a Victorian, the mountains are never cold. There's only damn hot, and rather pleasant, and all of that involves shorts and flip-flops. I took Clare Bowen's fieldwork book. I read a bit of it. I carried it's one kilogram arse for countless kilometers, often on my back. Things to read is good, but they have to be e-books. However much waterproof I thought I brought, I didn't bring enough. What I needed was sturdy plastic bags to put things in, particularly documents and electronic devices. I had some, then got by with 7-11 bags. My backpack, a fetching Hawaii branded thing I picked up while at ICLDC4 this year, isn't waterproof. In fact it funnels water into places where stuff gets soaked. Everything that I took that was made out of relatively thick material was very difficult to get dry. Things that are dark are easier to dry because they heat up in the sun. My laptop is of the more powerful variety. I love it, but it's a bit heavy, particularly the power supply, and the battery life was a pain. A thin and light ultrabook with 8 hours of battery would have been lovely.
Phones. I bought a bunch of Doogee DG850s, a no-name Chinese brand but somewhat respected. All but one failed quickly. Some sort of issue with water and the touch screen, we're talking about drops here, not getting dunked. I subsequently realised that a much better plan is just to get old flagship phones second hand. I'm sitting on a small collection of Nexus 5 phones now, thanks to putting the call out to friends. This is probably the best phone ever made and I have a bunch of spare parts to fix them up.
I relied on paper-based notes. I found them convenient to take while doing recording on electronic devices. After one catastrophe, most of my notes were destroyed. There's two possibly solutions: Quickly transfer notes to electronic forms (I could always have just taken a photo of them), or find some way to do notes in the electronic domain. I'm less convinced by this approach, I've never seen anything as effective as pen and paper. So this is more of a 'method', but it does underscore the need for document protection as well.
Now let's talk about things that worked well. I debated whether I should take a full-sized tripod. You can see it's a burden on the bike. It was worth it's weight in gold. A mini tripod just wont hold a full sized camera well. I ended up using the tripod for lots of things when it didn't have a camera on it including drying clothes! I took a Panasonic Lumix FZ1000 mirrorless camera, and I bought a fairly cheap shotgun boom microphone for the horseshoe accessory. This camera was godly. The battery life was brilliant. I recorded everything in 720p video just because I could, because there was no penalty, because I should shoot countless hours on the 64GB SD card. The audio was excellent. The only fail was forgetting to switch the shotgun microphone on, doh. Yes, I lost recordings because of that. I might think up a way to fail that but of course it's reasonable to perform a test looking at the level bars on the camera screen before you go. I chose that camera because it was a combination of fairly inexpensive, had audio in, and had good video recording capabilities. It delivered in spades. I'm sure you could do the same with any number of other models, but certainly mirrorless integrated lens units have their place in this work. We're not swanning around pretending to be a fancy pants photographer. We want something that works. There may even be a compact unit that has similar capabilities but typically audio is the tricky thing to find.
The Shad Zulu SW90 waterproof duffel bag, 85L capacity. This was a bit pricey but it was made for motocyclists. It also has a fairly baffling array of straps and what have you but at the end of the day, it lived through two typhoons, one of them it was on my back, on the bike, in torrential rain and not a drop got in. Proper compact, roll-up wet weather gear such as coat and trousers. Mine were Blizzard brand. At the start of my trip I didn't both much, I don't mind getting wet, it's nice and warm anyway. The problem is your clothes don't dry in 100% humidity and you have to find places to put items so they don't get damaged. If you're wearing proper wet weather gear with sealed pockets, you can just carry stuff in side. I also developed a fondness for one part of shorts in particular. They dried out quickly when nothing else would. So impressive is this I need to list what I know: they were 69% cotton, 31% polyamide. Blue Harbour brand bought at Marks and Spencer. Marketed as being water repellent. Another great purchase was a set of Gondwana-brand trousers, marketed as being quick drying, they had zip-off bottoms to convert to shorts. In terms of T-shirts, if you stretch them and can actually see between the threads, they will dry. Everything else wont.
Miscellaneous: I took too many low quality USB cables. I needed fewer proper solid ones, 24AWG variety for charging. I took a large USB charging thing with zillions of ports on it. I didn't use it for much other than charging a couple of things at once and wanted to use the high-current ports. In future I will take a smaller unit, probably something like a travel adaptor, with a couple of sockets on it. I took an iPad. This was questionable. It would have been fine if I loaded it up with eBooks maybe. I tended to use it to browse the web but writing emails etc is better on a computer, and you can browse the web on a phablet. I will think on whether it's useful for next trip. One thing it would be useful for is to show videos to people, but then Apple doesn't make that easy with iPads, so again an Android phablet wins out.
I took care of data backup with an SSD in a hard metal case. It was very small. I periodically copied off my primary data (from SD cards and phones) and secondary from my laptop. I made sure it was left at home, in a safe place, rather than being where my laptop was. I will investigate the possibility of using the cloud as my backup. I didn't anticipate having the bandwidth to do so. In the end I just needed a cloud service with enough storage, my Google Drive is nearly full. So maybe I need to sign up to a commercial one for more space.
My home-made battery bank/charger was absolutely gold. It turns out that I needed this to use a phone as GPS nav on the scooter and it was just the right size to go in the front scooter storage area. I intended this to be solar powered. I took home made solar panels to charge the unit. I used it for this purpose once, the rest of the time I charged it on mains since usually I wanted to charge at the end of the day when I got back home. Solar was a nice thought but turned out to be impractical. I'm now upgrading that charger with an additional quick charge port for my phone.
I bought a sort of zip-up mobile phone bracket thing for the scooter. It was terrible. I had to tape it on so it wouldn't jettison the phone when I went over a bump! It also turned out not to be very waterproof, despite the fact that this was it's one job... next time I will use the zip-up phone bags. They may not look quite as snazzy but they're a known commodity. I have no waterproof solution if I need to be charging the phone at the same time... and I'm not convinced I need it. Riding the bike in torrential downpours is not something that should be done for hours on end.
As a summary of these findings: A heavy tripod is worth it. Be sure every bit of electronics is necessary and decent quality. Keep clothes to a minimum, you don't need a week, what you're not wearing can be drying. I found shoes too hot. Flip-flops are king. Go overboard on wet weather stuff. It doesn't take up much space when it's folded up. Waterproof pouches for documents and gadgets are a very good thing.
Finally, some things I wanted weren't easy to get in Taiwan. DEET-based insect repellent. They seem to believe that citronella will do it. Bless them, but they're wrong. Bring Rid from Australia, Australia knows about this stuff. Analgesics can't be bought anywhere but in a pharmacy and even then in surprisingly expensive packets of very few tablets. Bring a bottle of panadol and have done. Hay fever and what have you. In Taiwan they try to treat this with antihistamine tablets rather than nasal steroids which don't seem to be readily available. Again, bring some from home if you need, and occasionally I would have given my kingdom for a simple Beconase sprayer.
