Review of the LG OLEDs -- it's time for a 4K HDR TV, but it still thinks it's a TV

A decent impression of an impressionist

I recently purchased an LG 4K OLED HDR TV. In spite of the high price, I am pleased with it, and it's made old HDTV look somewhat dull. There is now enough content to upgrade.

Read my review and also my comments on how the TV hasn't yet figured out that many of us just want it for streaming.

Tales of an Electric Car Road Trip and Supercharging strategy

I digitally removed a score of instagrammers trampling these lovely flowers.

This month we took an electric car road trip in the California desert to see the flowers. The idea of a road trip in the desert with an electric car would have been crazy not too long ago. Now it's becoming possible, soon it will be easy, but there's still lots to learn.

A taxonomy of the many choices in flying cars

Hoverbikes are their own special category

There are over 100 companies out there developing small VTOL "flying cars." And they're all making different decisions on several important design choices. I've written a breakdown of the key design decisions and what they mean, which forms a sort of taxonomy.

Nvidia simulator and Safety Force Field and other news from GTC

This week I am at the Nvidia GPU Technology Conference, which has become a significant conference for machine learning, robots and robocars.

Here is my writeup on a couple of significant announcements from Nvidia -- a new simulation platform and a "safety force field" minder for robocar software, along with radar localization and Volvo parking projects.

Visit to Lake Berryessa "Glory Hole" spillway gallery

A minor local spot of interest here is the spillway for the Lake Berryessa reservoir. Unlike most spillways, this one drains from the top on the interior of the lake. It is called a "Morning Glory" or "Glory Hole" spillway. From time to time, the lake level gets above that spillway, sometimes far above, and it creates something that looks completely wrong, like a hole in the fabric of space time. So we went up to photograph it.

Where's my flying car? Coming in for a landing...

Opener predicts the Blackfly will be for sale in 2019

Readers all know I love robocars and write about the tremendous effect they will have on our lives and cities. But a new technology, running about a decade behind but now real, is coming which could have even more dramatic effects, the e-VTOL or "flying car."

Autopilot review Update

Of course, just after releasing my review of Tesla Autopilot they announced new pricing and features, with some explanation of what "full self drive" is.

For now, it turns out it's still driver assist, but on city streets. It's an interesting question if that's a good idea. I offer some additional analysis and updates.

I still want better luggage solutions

The more you travel the less luggage you want to take. Our world where a laptop and phone can almost do it all, combined with the cloud, is helping. But sometimes you have to bring stuff in checked suitcases.

When you do road trips, especially outside the USA, you learn that most cars don't have the trunk space of North American cars, not even close. You're lucky to get two rigid body suitcases in the typical small car, 3 needs a car with special capacity.

We need a world where open source robocars are possible

An early student robocar at Stanford

We all love open source. But the usual rules of open source break down if every vehicle deployed on the road has to have gone through a complex and expensive safety certification process. You can't just download, patch and go.

So we need other solutions to allow the world of the tinkerer/hacker and the innovation and superior function it can provide.
