School? I could have called it Soldering 101, or Soldering For Dummies, but hey what do we do when we need to learn something that is a skill?, Well we go to a school. The word school is just a formal place of learning. So why do we need school for soldering There are a few reasons: You need to learn the best practices. You need to learn what solders to use and not to use. You also should understand how not to solder and why. And finally, you should understand the tools you need.   O ...
Protocols again? Are we ever done talking about protocols? No not really. And BTW this is really RSS version 2!  RSS v1 can be found on my other wordpress blog. This version eliminates most of special hardware and its bus and chassis. Most radios heads can be handled by a Arduino Mega256 as it will handle two radios or that is one radio head. If the Mega256 can't handle the job I can then use the Stellaris Launchpad from TI.    We will use one of my Gables G-3717 Dual Nav Head ...
Ok so what the heck is a RSS? The RSS is a central location in the simulation for all of the radio stuff. The Analysis NexGen can handle any type of radio interface, but not limited to ARINC-410, ARINC-429, MIL-STD-1553, or any thing else you can dream up ie. Sub Space Radio in Star Trek. The 5 in 1 pictured on the right is a ARINC-410 head, they are cheap and plentiful on eBay. Radios with dials general fall into the other category of other ie. you are on your own.  The ADF pictured on ...
Dah Rules! The selected processor must support all of the I/0 natively ie. no I/O Expanders. There are more out there, but I own these, with the exception of the Pi. The processors to be in the selection are: Ardunio Duemilanove Ardunio Mega TI Stellaris Launchpad Raspberry Pi Beagle Bone The Solution must be integrated with the Radio SubSystem or RSS. There must be two sets of protocols developed. Between the Control Head and the embedded processor. Between the embedded processor and ...
The Plan Continued. We need to pick a embedded cpu. The requirements are:   It must handle all of the GPIO (see part 1 for the I/O Table), or about 20 pins. It needs a USB interface for a data link to talk to the host. It needs to generate the BFO signal. It needs a PWM output to drive the meter. It needs to have a protocol designed for it. But I has to fit in to the Radio SubSystem or RSS architecture. We need to design a interface card. It should have a relay for the Dial La ...
.This is the ADF Control Head that I chose for my project.  It is a Collins 614L-8. they are plentiful on Ebay The Analysis    The Unit is tuned via a 400hz syncro transmitter. So it looks like I will have to find a replacement for the synchro.  The Loop Switch in the upper left must be rewired and the switch logic for the Band Selector Switch behind the Tuning Knob seems ok, but that will have to be verified. The Gain Control is just a 5k pot,  and the Function Swi ...
