Your transponder has to have software that accepts ADS-B+, and your GPS has to have software to output ADS-B+. Without the plus it is not legal. So you have to determine which software version added that protocol for both the GPS and for the transponder.

The switch is rated for 2 amps at 24 VDC. That probably equates to 3 or 4 amps at 12 volts. If an indicator lamp is chosen that uses less than 1 amp, it should be fine. The switch is avai lable as either normally open or normally closed. There is a 50-50 chance of getting it right. The original poster probably wants the normally closed s witch. Another concern is selecting the correct operating temperature. And there is the life expectancy issue when subject to the vibration of a 2 cycle eng ine. -------- Joe Gores Read this topic online here: http://forums.matronics.com/viewtopic.php?p=477046#477046 ________________________________ Message 3 ______________________________ _______ Time: 07:48:51 AM PST US Subject: Re: AeroElectric-List: Re: Simplest way for a go/no-go 2-Stroke E ngine Temperature Ind From: C&K A tiny keychain size infra red thermometers for $12. might be more useful and less trouble to set up.

This is probably an adaptation of the 'capacity sensor' widely used on touch pads for manual controll inputs. It senses a change in capacity. The two electrodes attached to the outside of the tank form a capacitor in which the dielectric is composed of tank material and air. When fuel fills up the air space, the capacitance goes up sharply and the electronics senses this. For metal tanks, they need to penetrate the tank wall to get at the change in air-to-fuel capacitance.

Still have to watch the max temp, though. Another option uses the Analog Devices thermocouple conditioners in a on-off switching mode. https://goo.gl/7ufeaL Here's a simplified schematic . . . Emacs! Instead of driving a heater control relay, one could drive an LED indicator light directly from the signal conditioner's output . . . This would let you connect directly to the cylinder head with appropriate thermocouple material.

Okay, looking closer reveals that this is a capacity fuel gaging system, not just a level sensor. There is a whole new class of liquid level capacity transducer products out there. Recent developments in resolving capacity has spawned a variety of low cost instruments that will measure capacitance with good accuracy down into the picoFarads territory. There's a pretty simple methodology for using pic/arduino DIY processors to implement your own capacity liquid level measurement system wherein the sensor is nothing more than a twisted pair of wires with insulation impervious to the liquid being sensed. For the product cited above, the sensor is either copper foil electrodes on the outside of the plastic tank . . . or some analog built into the probe. This could be paired with a comparator that drives a 'tank full' indicator light.

(He has some pretty terrific fuel level sensors, as well for the experimental crowd.) You install this detector at whatever level in the fuel tank you choose, and it alerts you when the liquid level drops below that point. The LED indicator is normally green when the level is above the "bingo" level, and if/when it drops below that point, it flashes red for 10 seconds, then goes solid red. Installation seems dirt simple, and it seems to work with just about any liquid. There's a video demonstrating it on that page also. Currently on sale for $69.95.

Only really use it when I want to run a tank dry. If the tank sloshes, then I do get some false alarms when it is bumpy. I use my float gages to alarm at 5 gallons left.
