Building a radio stack? (Read 753 times)

Hello guys...

Need some help.  I am wanting to build the basics of a pit..have some toggles, buttons, fans etc etc...and also a radio stack.  What I am wanting to do, I have no idea how to.  I am wanting the following:

2x Displays for Radio Freq
2x knobs to adjust display
AP controls (knobs, no displays, just to adjust altitude, AS, VS, heading, and buttons to activate each of them)
1x button to switch between COM1/2

Can anoye help me figure out what I need to buy???  I am using a KE72 (well, will be when I order it after next payday) to interface all my other switches with it.

What I need is for someone to basically tell me EXACTLY what I need...but keeping it as cheap as possible.  I am wanting to stay under $100, and will drop the displays if need be.

Anyone willing to help?

tunatuk,

Hi and welcome to both SimV and the Homebuild Cockpits Forum.

Unfortunately $100 sounds like a little "light" budget for the radio stack.  Seven segment LED displays are not cheap nor is the electronics to drive them.  With a LOT of electronics skills and a good scrounge......... you MIGHT be able to come up with stuff.... but if you had those skills... you likely wouldn't be asking the question  Wink.

One option would be to go "virtual" and use an old monitor to display radio displays via holes cut in the MIP facing.  But that wouldn't get you the controls...just the displays.

A Phidgets LCD module would get you a display and 8 digital inputs, 8 analog inputs, and 8 digital outputs.    That would likely create one "radio" when you added pots for frequency control and a couple of buttons for radio fuinctions.  Likely would have enough left over to become the AP controls.  The 8 outputs could light led function lights to indicate button pushes.  Check out the "Cockpit Building Resources" sticky at the top of this thread for info on Phidgets.

I use four Goflight VRP "radios" for the radio stack combined with a RP48 for the audio panel.  Somewhat expensive....but pretty realistic.  VERY easy to install and configure.

The KE72 is a great interface board....... VERY versaitile.

Hopefully someone else will have some suggestions here too soon for you.  Also check the past threads for likely topics.

best,

......john

If I understand this right, you don't want to access the radio stack on the sim ... if that's the case, then buy the seven segment displays at http://www.em.ca/~cockpits/main.htm CSI.  They sell the segments for 1.00 USD each and the holders for 5.00 USD each pre wired for the EPIC modules this is a Canadian Company shipping from North America.  HAGSTROM modules do not support 7 segment displays.

Hagstrom also has the modules for rotary encoders, NOT rotary switches, by using the rotary encoders you can assign the key board to see right rotation as the PLUS + key and the left rotation as MINUS - key functions.  Hagstrom  has informed me that they are capable of making a module for the 7 segment display, but I have not inquired further.

I am a new owner of the KE 36 USB and Break out board, don't forget to get two of the breakout boards, they hook up the switches to non solder terminals, then transmit the inputs via an included ribbon cable.  Setting up the commands is done through a windows interface, so you don't need any code writing skills.  The manual is VERY informative, you'll be really happy with any Hagstrom product, a good warranty and FAST support.
