A little while ago I acquired a Walkera Devo 7e from a friend, for use with my assorted R/C aircraft. This is a pretty dandy little radio in its own right, which speaks the Walkera Devo radio protocol. By doing nothing but reflashing it with Deviation firmware, you can add support for the Spektrum DSM2 and DSMX protocols. But if you're willing to pick up a soldering iron, you can accomplish a whole lot more for not too much money.
Long, long ago, when I first heard of Philips Ambilight, I thought it was one of the coolest silly things I'd ever heard of. Today, much later, I finally have gotten around to rolling my own Ambilight clone using an Arduino Nano and WS2812B strips. I did not have to write any code, because other people have already done it for me. Figuring out which people had done what properly took me the better part of a day, so I will now share my knowledge with you here. This should be a cross-platform (Win/Lin/Mac) solution, but I have only tested on Windows.
For quite some years now, my main mode of transportation has been a 1982 Mercedes-Benz 300SD, a base model-plus-sunroof 3 liter turbo diesel. This represented the budget version of the Mercedes flagship sedan, if you will, but still cost as much as a small house. I am finally moving up to something slightly newer, a 1997 Audi A8 Quattro. Like the Mercedes, when it was new, its price was similar to that of a small home. There are other similarities and differences, and only recently have I had the opportunity to make any kind of comparison.
Look, it's not that I regret buying the Audi... wait. I regret buying the Audi, any time I'm not actually driving it, which has been less than two months in a year so far. But maybe those regrets will vanish as I continue to iron out problems. It's that I really miss my Impreza.
Quite some while ago, I bought an Audi A8 Quattro for what seemed like a good price. It was not a bad price, it just wasn't a good price after all. It's been a learning experience, which is automotive slang for I should have spent more money. I haven't become an expert by any means, but I've got a good overview of the vehicle, especially the engine. This is partly because I used Google to translate VAG1 SSP2 105, 161, and 162, which are "V8-Motor", "Audi A8", and "ABS 5 ... Audi A8" respectively, and partly because I've replaced both head gaskets. The following text is adapted from some text I wrote in response to an email question, which came in response to a post on QuattroWorld A8 forum. I thought it might be of interest to others thinking about doing a head job on the 32 valve Audi V8 Motor.
Some little while ago, I picked up an e-Flite Apprentice, a fairly common foam "trainer" model airplane which is normally sold "ready to fly" with everything but the battery and charger. It was part of a lot of stuff that I picked up for ten dollars, and came without the radio. First I repaired it and mounted a HobbyKing HK-T6A v2 radio, but I quickly decided that it should be more than just a plane.
When I assembled my quadcopter, I always intended it to become a drone, that is to say, with autonomous features. The typical use case for the hobbyist is intelligent failsafe, specifically return-to-home or "RTH" capability. As I've assembled the parts to accomplish this, it's made me consider how to achieve the same thing for my plane.
Well, I finally built me a drone so's I could fit in with all the cool kids. What follows is a short description of my experience with helpful links for someone else who would like to build a substantially similar quad. I built basically the cheapest quadcopter you could use for anything more than just crashing into stuff, a SK450 whose parts were primarily sourced from eBay — and usually with the very cheapest parts.
I'm a big fan of the Fallout franchise, so when I discovered Fallout Shelter, I was happy to see a new member of the family. It's actually a pretty engaging little game, but it has some ugly flaws that I find frustrating, so I'm going to complain about them.
