Hi, I am doing the radio, but I have problems with the power supply, which source would have to use? I am testing with 2 cell chargers, one has 5.1v 2A and the other 5v 850mA, testing with both does not turn on all of the 7219. When I post more advanced image of how I go,  also create a thread for rudder pedals, please if you can help me with that. Thank you!! |

Hi there Pablo. I'm using a PC Power supply to power the Radiostack. As for the rudder pedals I made them but i'm not quite happy with them, if i build a new one i will surely make a thread about them.

Hello and congratulations on your excellent work! could you please tell me how to connect the dual rotary encoders and the switch buttons between them and to the arduino please?
hope to hear from you soon!
Brian.

Brian. Hi there Brian I will try to make a sketch for you as soon as I can. Regards AlbEagle. |

How are you using a PC power supply to power the radio stack? I was under the assumption that the power was being provided from the 5V on the arduino?

I was under the assumption that the power was being provided from the 5V on the arduino? also how is the avionics master switch wired? is it going straight to the arduino so that when you switch it on it turns on the power to your radio panel? or is the power somehow wired into the computer power supply? |

This is the reason I am powering the displays separately with a pc power supply to be safe so nothing will happen to the Arduino board. * The master switch is connected the same way to the Arduino as all the others. Powering the radio through the main switch is achieved through Mobiflight. The reason why it has to be done with mobiflight and not with a switch is that the max chips used on 7 segment displays have to be initialized every time you power them on which means if you just power them off, you have to power off the Arduino as well and power it on again to be able to get the values. So it is because of the max chip that you can't just do it physically with a switch. The logic on the mobiflight is easy for instance, you say if Power switch is on and Avionics is on, than Com1 display = on. I have already programed it and you can download the mobiflight config file from the website. Regards AlbEagle |

I understand why you are using the computer power supply to power the panel but im uncertain as to how. I have never wired anything this complex, most of it I can understand ok but the power supply is confusing to me... not to mention it makes me nervous about catching something on fire! haha. Is there a way you could easily explain exactly how you wired it? I have several old computers laying around that I could easily rip out the power supply, are there any particular ratings I need to look for? Thank you for explaining how the Avionics switch functions I was actually hoping thats the way it worked. Your website is like the jackpot for DIY home cockpits, THANK YOU! |

Actually it is easy. Just check the picture below it should be self explanatory. If you still need help just let me know.  Regards AlbEagle |

wow that does seem pretty simple. Im going to attempt this.. if you never hear from me again its because I burnt down my house or electrocuted myself... haha THANK YOU!

Dear friends, above is wiring system of power supply of 7-segment displayes using the pc power supply. I need explain why is the green cable connected to com. Is the COM the same as Ground? Can I power up the Arduino with different power supply and the displayes from different power supply?
Thank you very much Filip Dymák (Czech Republic)

By PC Power supply you need to short Green with COM in order for the Power supply to work. You can power the displays from different power supply the the arduino, in this case you have to connect arduinos GND to this Power Supply's GND. |

also create a thread for rudder pedals, please if you can help me with that.
