    Subject: Re: AOA
    From: "Richard Pike" <thegreybaron@charter.net>
    Why could you not make an AOA indicator using a fuel gauge assembly? The sender typically uses an arm that changes angle and sends a signal; instead of the wire and float, make a counterbalanced vane that would move in the airflow. Mount the gauge on its side, and now you have a needle that goes up and down at different vane angles. Ideally you take the gauge cover off and instead of empty and full, you paint on angles of attack up to stall. You could try something like this first: http://www.ebay.com/itm/Universal-52mm-2-Car-Fuel-Level-Gauge-Meter-With-Fuel-Sensor-E-1-2-F-Pointer-/401028163857?hash=item5d5f242911:g:sHEAAOSweuxWSo-T&vxp=mtr Looking at the sender unit in this set, if you cut off everything you didn't need, the sender itself would be about 2" across, plus however big your vane is. Once you got that to work, but say you wanted a lighted gauge instead, one that went up and down, you could try something like this: http://www.ebay.com/itm/Universal-Motor-Motorcycle-2-Fuel-Meter-Digital-Display-Fuel-Ratio-Level-Gauge-/201502529749?hash=item2eea7c98d5:g:nr0AAOSwYIhWlint&vxp=mtr Now you have led's that go up and down as your AOA changed. And if you repainted the face and mounted it upside down, you have yellow and red at the top. Then stick the gauge in a little holder that sits on top of your panel so it is in your immediate vision while you are on final: http://www.ebay.com/itm/52Mm-2-Adjustable-Swivel-Dash-Mount-Single-Racing-Gauge-Cup-Holder-Pod-Bracket-/172060327859?hash=item280f983fb3:g:F8IAAOSwGotWlXS6&vxp=mtr Seems to me a fairly simple exercise in making your vane assembly light and responsive, finding the best airflow location, and doing some calibrating. -------- Richard Pike Kolb MKIII N420P (420ldPoops) Kingsport, TN 3TN0 Would you consider yourself to be a good person? https://www.youtube.com/watch?v=VWcDXT6pH7A Read this topic online here: http://forums.matronics.com/viewtopic.php?p=452018#452018

    From: Herb <Herbgh@nctc.com>
    My first AOA design was to use a small nuclear reactor coupled to a scintillator...hooked to a high voltage shock device in the seat of the plane.... but the engineering would take too long... :-) so how about this...a linear potentiometer hooked to the air vane(some weather protection) ...two leads run to an indicator on the panel... the indicator being a Milli volt meter...in series with another small pot /AA battery to adjust the meter reading . Meter would be over laid with green and red markers... simply adjust the potentiometer on the dash into the red when stalled onset is sensed..

    Sounds good, you guy's let me know when you get them finished. It appears that my work is done here. :-) For me however, I don't have room on my panel for another gage, so some form of lights would work the best for me. Hopefully one of us "Kolbers" can come up with something that is worth doing.

    actually the voltage indicator bar/leds could be made to work.. I seem to recall the order is red , yellow and green .. Just turn it up side down.. didn't like my first idea?? The stun gun in the seat surely would be spot on??? :-) On 01/16/2016 09:21 AM, Larry Cottrell wrote: > Sounds good, you guy's let me know when you get them finished.

    Moving An arm past a bunch of solder blobs sounds like a bunch of drag and sticking. Let the wind vain turn a pot. (Potentiometer) It seems in the RC world there are progressive led lights that respond to changing voltage. Run 12 v and ground to the sides of the pot. And the center will vary from 0 to 12 volts when the pot is turned. You could limit the travel of the wind vain to limit the possible output voltages, or put resistors in series with the 12 v and or ground terminals of the pot. This would keep the center outlet of the pot voltages within limits of the led light bar voltage indicator. The total resistance value of the pot would be determined in part by the max or min current requirements of the led voltage indicator. IE: a 5 k ohm or a 10, 15, 50 k ohm pot. The greater ohm value of the pot and still be able to drive the led volt indicator will consume the least amount of power. Boyd young

    Subject: Re: AOA
    From: Herb <Herbgh@nctc.com>
    The cheapest, says frugal Herb, is the 3914 led 10 segment driver...the 10 segment led with green, red and yellow leds...two or three resistors..9 volt battery..or 12 volts if available and three wires going to the vane and pot on the wing or strut... The schematic is here: http://www.eleccircuit.com/the-led-display-voltmeter-in-probe-model/ and the circuit can simplified by removing and combining r2 and 3 into a 100k resistor..removing the two voltage leads...120 v and 1.2 volt range.. The pot will have the slider going to the probe...one end to 12v and the other to gnd.. the vane needs to be set screwed to the pot such that one can trial and error the stall point.. Then again...the 100k resistor or the 909k (100k is ok) could be adjustable and the pot could be accessible in flight... 2 dollar parts on ebay..circuit board can be some perf board with .1 spacing...think that is the spacing??

    No, a blood pressure gauge would not likely work. At least, I'd doubt it. T he gauge the inventor/seller uses is the Dwyer Minihelic II, model 2-5002. 0 -2" w.c. The commercially sold unit has a new red,yellow,green silk-screene d face. The pitot mast is a nice afternoon project. See the gauge below.

    Yep...2 inches of water(used these gauges with IBM and Storage Tech) is equal to 3.73 mm of mercury...and blood pressure gauges start at 20 mm of hg... not sensitive enough...

    Run one wire to the arm. make a "board" with > 4 or five wires sticking through the board with a solder lump I haven't thought this through.. but simply to enlarge on your idea, try a TPS. Throttle Position Sensor. They come in all shapes and sizes. Basically a rheostat.

    If you used a pot, or the TPS you could drive the light-bar and/or a sound generator. It could be fancy or simple. You could use a 555 timer, the pot input could change the tone frequency. It isn't a sound chip but the output pulses can drive an earphone or amp or whatever. You can tailor the duty-cycle, the frequency of pulses, etc. there are interactive software tools available free that will tell you what values of caps, resistors and pots to use. And how to wire it. Is really simple. -------- GeoB &quot;Members of Congress should be compelled to wear uniforms like NASCAR drivers, so we could identify their corporate sponsors&quot; Read this topic online here: http://forums.matronics.com/viewtopic.php?p=452044#452044

    I could imagine a group of Reed switches laid side to side with a 50 percent offset. One set on either side of the magnet. Pending on the physical sizes of the switches would determine the accuracy / resolution of the devise. .. A pots accuracy may depend on the size of the wire , and the tolerance in the led light bar. A 10 segment led bar set at 1 volt per segment, or a 10 segment bar at a quarter volt per segment. Big difference. Boyd
