Wiring up a tail light: How to keep it out of the way?

If you’re riding at night, you need a tail light. If you’re riding a lot, you want one that’s wired in, so you never leave it at home by accident and never need to worry about powering it. But how do you wire the thing up?

In the past, my solution has been to ziptie the wire to the frame and the rack, but more than once I’ve accidentally broken the wire while moving the bike around or arranging heavy gear. So now I’m trying something else: Plastic adhesive!

I taped the wire down over the fender, leaving most of it exposed, and then I busted out the JB-Weld.

Using some rubber gloves and a paper towel, I applied enough adhesive to cover the wire, then cleaned up around it to make a smooth ridge running almost the entire length of the fender. When that was set, I peeled off the tape and covered the remaining gaps.

The result: A wire that is as out of the way as possible, safe from corrosion, and won’t get snagged by rack equipment.

Improvised strap holders for Ortlieb Sport Packer Plus bags

The long carrying straps for these Ortlieb bags are really handy…

Until you want them out of the way. For example, when you’ve placed the bags on your bike and you don’t want the straps getting tangled in your wheels.

What’s a busy bike tourist supposed to do with these dang things? Unclip them and stow them inside the bag, every time? Leave them clipped, but drop them inside the bag, where they’ll get wrapped around bits of luggage?

Here’s a solution. It works so well it should probably be part of the original bag design. First, get ahold of a bag of extra Ortlieb doodads.

Then get ahold of two velcro straps. These are pretty common; you can find a dozen different kinds on Amazon. Using the same brass punching tool that Ortlieb supplies for mounting pockets and water bottles, poke a hole near the lip of each bag, on the side where the lid is connected. Then poke a hole through each of your velcro straps, near the buckle.

Use a nut, a screw, and a couple of washers from the spare parts collection to attach each velcro strap to one of the bags. You can now fold up the carrying straps, and secure them neatly to the lip of each bag, using the velcro straps like so:

It’s very tidy, on and off the bicycle. Now you can keep the straps attached and available all the time, but totally out of the way then you don’t need them.

Using USB-C to charge a Mavic Air?

Somewhere I got the crazy idea that it would be fun to bring a camera drone on my bike tours. Every bit of weight counts, of course, so I got a portable one called a Mavic Air.

It’s great, but it uses a custom battery that can only be charged with a large power adapter, and the adapter weighs half a pound. I’m already packing a 5-port USB charger that has one USB-C output suitable for charging a MacBook. That should put out more than enough voltage to charge the Mavic battery. Why can’t I use that?

Well, it turns out I can.

This is a little widget called a PD Buddy Sink. You can plug it into a USBC charger like so:

Then you can program it to ask for any voltage that a USBC power source can supply, and make it available. For example, 15 volts at 2 amps, which is enough to feed into this Mavic Air charger designed to plug into a vehicle’s accessory port:

I removed part of the casing to expose the wires, then linked them up to the PD Buddy Sink, like so:

Then I decided to get arts-and-craftsy. I formed a gross looking extension to the car adapter case, using some two-part epoxy and silicone glue. Now it looks like the adapter is digesting the PD Buddy. Mmm! Delicious!

Using my MacBook, I then programmed the PD Buddy Sink to ask my power adapter for 12.5 to 15 volts at 3 amps, with 15 volts preferred:

And after writing the configuration to the PD Buddy, I plugged it in, and presto! It started charging.

On the left, I’m using the 5-port USB charger to charge my MacBook, with a digital USBC power meter attached. The MacBook has negotiated for 20 volts and is getting about 19 volts. On the right, I’ve plugged the same USB charger into my Frankensteined car adapter, and it’s negotiated for 15 volts. Success!

(If you look closely you can see the adapter is pulling only 0.005 amps. That’s because the Mavic Air battery is fully charged.)

So, was it worth it? Well, I weighed my new Frankensteined adapter, and it’s a little less than 1/4th of a pound. So I’ve saved 1/4th of a pound, but I’ve lost the ability to charge my laptop and my battery at the same time, and lost the two extra USB ports that the power brick provided. Nah, it wasn’t really worth it. But I had a good time!

Books On Bikes: Michael Wolff: Fire And Fury

I general I want this site to be apolitical. But to give an honest review of this book I need to say up front that I’ve always been a social liberal (and a fiscal conservative), and if your leanings don’t match mine you won’t be able to relate to what I write here.

I understand how people on The Right in my country are unmoved – or trying to be unmoved – by the various character and behavior flaws that the media has unearthed in Trump, and paraded around in front of everyone for years. The Right wants the focus to be on political actions in office, not hijinks in past bedrooms, and I can see their point. But meanwhile, people on The Left, including myself, were wound up into a frenzy by the seemingly endless scandals about the man, and the humiliating disaster of his being actually elected. We believed – and almost all of us still believe – that Trump is so maladjusted and inept that he will eagerly destroy the country from the top down. That’s a lot of fear, and we need to deal with it.

And that’s why I say: Thank goodness for this book. I feel so much better after reading it. Not because of the fears it confirmed for me, but because of the suspicions and fears it has laid to rest.

All that crazy Alt-Right stuff? That was Bannon. Trump barely cares about it, and now Bannon is persona-non-grata to the White House. The executive order banning travel? That was Bannon failing to understand government, wanting to cause hand-wringing amongst The Left and make a personal splash. Which it did. The Left ate it up. Was it a shot across the bow to signal a strong, rigorous follow-up? No. It was exactly what it looked like: Half-baked incompetence, from a man in a hurry.

All those unfilled positions in cabinets? That wasn’t the beginning of a big, determined, “disassemble the apparatus of the state” push. That was the fallout of the Trump campaign so thoroughly expecting to lose that they had no plans in place of any kind for a transition of power, then remaining so dysfunctional that they could not assemble a plan before day one. Or for months afterward. Can you imagine Trump sitting down, perhaps with a piece of paper and a pen, and saying “Okay, let’s make a plan?” And then sticking with it? You can’t. And for good reason.

It’s true that Trump does not, will not, read anything longer than a few lines, unless he’s acting via a teleprompter. Not one-page memos, not policy papers. Lectures bore him. Presentations have to be slide shows, with splashy images, and no nuance. He cannot become even halfway informed about any complex subject on the presidential desk, and the people around him know this, and they spend all their time “managing” him. That might seem like a threat – he would be eminently exploitable – if he wasn’t thoroughly unpredictable and occasionally irrational.

I think Trump wanted the title, but not the job. He wanted to glad-hand and play golf, throw fits and fire people and lob insults, and have all cameras pointed at him all the time. That’s how he saw the presidency. The rest is bean-counting crap that he’d rather avoid. Better if he had not been elected, but the silver lining is that any other Republican candidate would have given the Republican congress far more power. Instead, they have spent a year feuding and lobbing insults.

I’ve already turned my attention away from any media he generates, and almost all media about him. I’m convinced that this presidency will spin its wheels and get nothing done for four years, and when the door hits Trump’s butt on the way out, he will be abandoned to auditors and lawyers like a chicken bone to dogs. There is a lot of panic these days that Trump’s kind of politics and relationship with the media is a new normal, but I see him as a correction: He’s the shirt-ripping self-sabotaging one night stand that the nation is having, after our steady boyfriend Obama broke up with us and tried to pawn us off on his friend Hillary and we rejected her in an angry display of pique. We don’t want your boring old scraps! We want fire, and fury!!

And here it is.

This book made me laugh out loud a dozen times. It was brilliant stress relief, and had plenty of food for thought. Government is too established, and full of too many sane people, for one grumpy old man to tweet it apart, and I really don’t have to worry so much.
