I published previously Arduino LiXXX battery monitor & altimeter + vario for JETI DUPLEX with Arduino Pro Mini and MS5611. It would be perfect to have all telemetry data and alarms available directly in the transmitter, i.e. without JETIBOX device. One of possible solution is to use radio with OpenTX firmware. Unfortunately, new radios with ARM processor (9XR Pro) don’t have JETI telemetry as the option in Companion software (ver. 2.2). But when you are looking for protocols available, FrSky D system is available in the menu.
I would like to present here my code for Arduino Pro Mini as the converter from JETI DUPLEX (non EX) protocol to FrSky D telemetry system.

I published already LiXXX accumulator monitor (PIC12F683 based LiXXX accumulator watchdog) and the similar project for JETI DUPLEX (PIC12F675 battery monitor for JETI DUPLEX).. All of the designs signalize voltage of three cells in LiPol / LiIon / LiFePo battery, either by buzzer beeping or by by values displayed on JETIBOX LCD and beeping through JETI Tx module.
Now I am introducing another option to have more complex data from RC model through the JETI DUPLEX 2.4GHz system.

It is perfect to have fast way to produce PCB. For those of us, who have CNC milling machine available, is to mill the „printed“ circuits one solution. It requires to have suitable milling machine with sufficient accuracy, working tool (HPTec V-groove cutter type 802.9 seems to be ideal for me, it is possible to buy at http://www.cncshop.cz/drazkovaci-freza-30-600-v-profil-typ-802-9 ) and of course the software, which can convert PCB design to G-code for CNC milling machine. As far as I know, one of the most widely used PCB design software especially among the enthusiasts is Eagle from http://www.cadsoftusa.com/. One of its feature is create the user language program (ULP), which can be used for many purposes and one of them is to generate G-code.
