That's where I'm leaning, which means the entire class can be taught inside the classroom like most of the other classes are. I would think there should be a chapter each on each "thing" kids need to know about (perhaps homes, vehicles, measurements, debugging, PCs, etc.). In each chapter I would think it could dive down into the "systems" involved such as the cooling system for a car, or the plumbing system for a house or the electrical system for a computer. > phenolic impeller in the water pump detached from the shaft you learn > about cooling systems to say nothing of Chrysler's decision to use a > plastic impeller. Repair starts with debug. Debug ends with isolation of the failed component. But debug starts with understanding the systems & isolation of the failure. Without understanding of the system, there's no repair possible unless we teach the kids to just throw parts at the problem. Admittedly, a _lot_ of cars are fixed by people throwing parts at them! :) > Chrysler product also taught you not all threads a > right handed. My first Chrysler was a New Yorker which, as I recall, had reverse threaded lug bolts on one side, but normally threaded lug bolts on the other. Nobody told me this. After doing the one side, I wrenched off two or three before I realized "something" was very wrong on the other side. There were no "warning labels" in those days. :) > I'd guess the average high school kid knows as much about how a car > works as how their iPhone does. It's all magic. This is a good observation, where we could add a systems approach to how basic electronics work also (sci.electronics.repair). |

My first go around was with my '82 Firebird which was early in the computer controlled game. It would run fine, stumble at odd and inconvenient intervals, and then run fine. Carb problem. but what, with the oxygen sensor, etc. Of course, running down the tree the measurements were on the low side of the acceptable range. I finally pulled the carb. There was a solenoid controlled valve to control the mixture. The problem was what looked like a little piece of neoprene that would randomly hold the needle open. I didn't feel bad as the guy running the project was having problems with his Pontiac and it was in and out of the shop as they tried to debug it. His son was the service manager so they weren't screwing him over. Another friend bought a Cadillac around the same time that also turned into a shop queen. He went to visit the car one day to find all the mechanics standing around poking at the computer like it had fallen off a passing UFO. > Nobody told me this.

Most of them did have an L stamped on the end but who looks at the end of the stud when changing a tire? >> works as how their iPhone does.

We have a new library that finally opened after a year delay for the virus. It has a large and well-equipped 'maker space' that I'm hoping attracts at least some kids. There are several 3D printers, laser cutters, work stations, 3D scanners and so forth. I think there is a selection of Arduinos and rPis with peripherals too. The library also subscribes to Make magazine. https://makezine.com/ There a media labs and so forth for the kids that swing that way. The opportunities are all there and free except for nominal charges for the 3D printer materials. The question is what per cent of the kids will make use of it. I don't have high hopes. Like it always was the smart kids will have a field day. The rest will be watching TikTok videos and could care less. Like Shaw said when defining 'horticulture', you can lead a whore to culture but you can't make her think. |

In NC the amateur radio plates cost more , Last time I checked they cost between a regular plate and one of the plates with letters and numbers of your choice. There are other plates like clubs that also cost more than regular plates |
