GPS Units = Show road steepness?

Also Zen's idea that you can make enough of ANY bicycle component to qualify it for custom fabrication is WAY over the top. You have absolutely no qualifications to be able to make that comment, so Unless you've had direct conversations with the senior design staff at Garmin you might want to keep your ****ing mouth shut. yeah yeah, we know, you sent them an email and they told you they were using devices from the Mirochip DSP family, right? I wonder if he knows what it cost to manufacture custom chips that will be outdated next year because someone gives their's another feature. A custom ASIC doesn't go obsolete until the manufacturer determines it no longer meets the requirements, ****ferbrains. Speed averaging for display isn't the world's easiest problem and they are doing that in a continuous update. Your stupidity know no bounds. Average speed is calculated by distance over time. That's two numbers that are constantly updated, and a simple math function that constantly updates a third. That number is converted to a display map. This is difficult? Maybe for you. Since the altitude problem requires two inputs minimum to an ADC there is no possibility of making a custom chip. wow....no, calculating altitude doesn't require two DC inputs. A barometeric pressure sensor has one analog output, ****ferbrains. Even calculation through GPS is done by a serial data transfer from the GPS receiver to the microcomputer, unless of course you can give us a link to a GPS receiver that has an integrated shift register designed to mate with a data bus (yeah that would make all kinds of sense for a device that processes data rates as slow as GPS....derp) And he doesn't seem to know what a gate array is or what it does. It's pretty clear, I know way more about it than you do. I've written VHDL for FPGAs, and not just once. I've been on a team that developed segmentation and reassembly chipsets for sychronous optical networks. The combinatorial logic device that was part of the chipset was a 240 pin Altera chip. |

The cost of those 2 screws is not their material value but the time of the worker who has to screw them in. Or a combination of the two :-) But the point was that the elimination of the screws reduced costs sufficiently that the company saw fit to made a cash award for the suggestion. -- Cheers, John B. |

And/or the slight slowdown of production time required to put them in. - Frank Krygowski A guy I worked with on the FB-111 test program got an award for installing two mounting bolts from the other direction as with the bolt heads out it took for ever to remove and replace the object while with the nut end out it took only minutes. As an aside, that airplane was a whole bundle of horrors as far as maintenance went. -- Cheers, John B. |

In my 1965 all the dash controls are diecast zinc. On a 1966 they're chromoplastic. I always imagined that somebody retired on that change. That was probably either the design department's innovation or perhaps engineering :-) -- Cheers, John B. |

Years ago, while an undergrad, I worked summers at a US govt installation that shall remain nameless. They had an employee suggestion program, which offered cash prizes. This was during the second 1970s oil price shock, and saving energy was big. One of my cow-orkers submitted a suggestion to remove all the olive drab paint from the windows of the building where he worked, so God's free sunlight could reduce the need for electricity. He got a cash prize. Several months later, our hero submitted a suggestion noting that classified material was handled in the building, and someone without the appropriate clearance might look in through the windows. He got a cash prize. Except for all the money wasted, there's a certain beauty to that story. That guy played the system like a fine violin. |

I surmised that you enjoyed arguing about it because you continue to do so. To be clear, I haven't been arguing with you. For an example of my argument style, refer to my exchanges with tom. Rather, I enjoy the conceptual discussions. If you started on code structure, you'd put me to sleep. Hard times indeed, when an exchange of insults is sold for the price of an argument. A proper argument requires, well, arguments: propositions supported by logic, based on articulated facts. Animation is good, but rancor and invective are not required, nor seizing offense as though it were higher ground. I think Monty Python did a bit on that. I have seen firsthand, in those I love, how a little brain injury can rob a person of any ability you can name, and some you can't. To walk, to speak, to remember your childhood, to remember whether you had breakfast, to plan ahead, to hold one's tongue, all can be lost. Some say "there but for the grace of God go I". No matter how you say it, it is well to recognize that there is no natural law that prevents such a thing from happening to any of us. I try to remember that before I post. A "draft" feature in the newsreader helps. |

On the other hand I don't know how these previous "quartz" clocks were designed and constructed so I would be working from a point of zero understanding of what happened. |
