> Yoyodyne was introduced as a fictional defense contractor in Thomas Pynchon's V. (1963) and featured prominently in his novel The Crying of Lot 49 (1966).
Btw, Lot 49 is a wonderful book and chock full of little cultural memes like Yoyodyne.
I'm not affiliated with the project, but I think would be unfortunate if someone was turned away using or contributing to the best or only opensource tool chain for a number of processors (eg the paduak family) because someone claimed the project was terribly run.
Please consider updating your comment.
The STM8S discovery board for this is $8 and in stock at ST and Digikey.This includes the target system and the ST-Link programmer. There are free commercial tool chains and the open source SDCC toolchain.
When was this? What version? Thanks.
Who show up three hours later and shoot your dog.
I use an Iwatani 35FW tabletop butane burner for wok cooking which works much better than my gas stove. It claims 15,000 Btu vs my stoves 7,000. I suspect both claims are inflated, but the Iwatani will boil a pint of water in 1/4th the time of the stove. The wok is acceptably stable on it and the flame pattern is usable if not ideal. The butane cans are well under $2 and will make several meals per can. It's a bit pricey ($100-ish now) but mine has lasted six years of frequent use.
Another director would have used practical special effects (models) to film dragging the steamship over the mountain and riding it down the rapids. Herzog dragged a real steamship over the actual mountain and he and the film crew rode it down the rapids.
In "Aguirre Wrath of God" the conquistadors war party lose half of their equipment when a flood sweeps one of the rafts away. This was not part of the script, during on location shooting an actual flood swept one of the movie crews rafts away with a lot of the equipment and props.
This set of blog posts that turned into a book is a great history of the underlying technologies that ultimately led to the computer, from the discovery of electricity onward. It's not a complete history of science, as it focuses on just one area, but it really brings out the nature of the interaction of discovery and practical development within their social context. I found it fascinating and enlightening.
The rim deflects inward as it contacts the ground. This is controlled by the stiffness of the rim. The deflection untensions the spoke. The cycle of tension/untension as the wheel rotates causes fatigue and also if the tension reduces to near zero allows the nipples to unwind. A thinner spoke elongates more for a given tension, so the rim deflection reduces tension proportionally less.
For example, given a thin spoke that elongates 5mm under tension, and a thick spoke that elongates 2mm, a 2mm rim deflection reduces tension 40% on the thin spoke and 100% on the thick spoke. So the thick spoke will fatigue and fail faster.
Ideally use the thinnest spokes that can deliver the desired wheel tension. This is not commonly done in cheap wheels because thin spokes have more windup and more spokes interact when truing so the build takes more time and care.
Official "Discovery boards" from ST include a programmer and debug connection for under $10, and cheap dev boards are plentiful. Open source C compiler SDCC, and free tools from ST.
There is also a very good Forth [0]. Even if Forth is not your thing the site has a lot of good information on STM8.
The book also has a good section on ingredients and techniques. Many of the recipes are available in her other books (all worthwhile, Fuchsia is my hero), but sometimes slightly simplified here for accessibility and speed.
