    Another reason for Open Source. Patents, trademarks, and copyrights provide protection by denying anyone else the right to infringe. They are both good and bad. They protect the sometimes large investment a company makes in R&D by allowing the company to realize a profit over time. That is the good part. The bad part is they stifle innovation and keep prices high. Whenever the market is distorted, there will be winners and losers, but in the long run we need this type of regulation. However, I think Fluke made a mistake in this trademark and it has cost Sparkfun and their customers a chunk of money. The solution is to overhaul the intellectual property laws, but that won’t happen overnight.

    Remember, “If it works, its a Fluke”

    I already wrote “I will not throw spit wads in staff meetings” 100 times, now I need to look up how to spell DUNCE.

    Reading the circuit diagram correction notes a second time, Bob realized it said “mark should show cap”, not “Marge Simpson shower cap”.

    We can’t present at the venture capital meeting while wearing the same shirt. We need to somehow demonstrate some individuality.

    Accuracy can be thought of as how repeatable is each pulse. Consider the mythical monopole magnet and detect only the rising edge. If you label that as 0 degrees, will it always be 0 degrees, or will the reading wander from 359 to 1 degree? Will it wander from 350 to 10 degrees? How will RPM affect accuracy? I think it would be fun to build a car distributer that will use a knock sensor to advance timing for max engine efficiency under all conditions for a vintage engine. Part of that project would be to know where the crankshaft rotation is to less than a degree. I don’t have to measure each degree, I can interpolate if the readings have accurate repeatability.

    These are trying times for many people. A little kindness goes a long way. I am not a government employee, but I appreciate what you are doing. Thanks!

    Why not use a combination of old technology and new for the VSI. You have a barometric pressure sensor, so add another barometric pressure sensor inside a tuna can with a very small hole in it. Vertical speed will be a function of the difference in the pressure readings. Empty the tuna can, install the sensor, epoxy the wire hole, solder or epoxy the lid back on, and drill as small a hole as you can for starters. As you know, mechanical VSI gauges are just an aneroid barometer with a small hole in the bellows and they work quite well.

    If we want better results for next year’s Consumer Electronics Show booth, we have to increase our marketing budget.

No public wish lists :(
