We have another source of Total Energy Compensation (TEK) probes on the market. It can be bought in our Pit.Lab.Shop. Both types of the probe are available:
- probe for horizontal mounting on tail.
- probe for vertical mounting on the fuselage
Probes has length 170 mm and about 11 g weight. Are sold with 2,5 m of silicone hose and plastic connectors. Bigger connector is for easy disconnection the probe after flight, the smaller is for connecting with variometer's pressure sensor nozzle.
The probe allow to compensate changes of kinetic energy made manually by the pilot pulling or pushing elevator stick. Pulling the stick, we made the glider climbing in cost of it's kinetic energy. Not compensated variometer (without a TEK probe) will indicate climbing, because glider in reality will go up, but it is not caused by thermals. Compensated variometer except static pressure will receive from TEK probe also negative dynamic pressure. The negative dynamic pressure is proportional to speed and change of it also will be "visible" by variometer. So correctly compensated variometer should not indicate changes of altitude made by elevator. The probe will work with SkyAssistant and with all other variometers.
Today Rémi send me plans for the Pitot probe and some pictures of his work.
The plan of the probe:
Some users ask about possibility to turn vario signal off. I can code it on "hard" without possibility to change, but it is'n my style. I like all to be configureable :-)
My proposition is anoter configuration window oriented on PPM. Some of that functionality exist in message window, but is "message type" oriented. Here is the same, but from other point of view: "ppm value" oriented.
One of the friends ask me about 100A current sensor for his OSD. He needs measure up to 100A and sense the signal by Analog to Digital Converter (ADC) with 2.5V reference voltage. I can prepare that sensor but it is good idea to present method of modifying sensor parameters to obtain requested parameters. Especially it consist ADC reference voltage, because every project can have other demands. On the current sensor schematics I calculated parameters for 5V ADC.
