Well the next victim is my LAMBDA LP 411 FM.. This needs the ER.. Picture 1 tells the tale.  I need a new meter new binding post (black) I should have that at least. Also the current meter needs both a new lens, and scale the meter itself looks ok.  The meter looks like a standard 1.5 inch GE movement (ebay).  The current limiter shaft is bent, I don't know if that can be fixed.   By looking at the yellow triangle it said 81/82  but the orange tag says: 1972/73.   M ...
Well here we are now trying to get some power supply working for NexGen. Well I have luging this beast around for more than a few years, and I need some juice for my projects. It seems that my Kepco JQE-6-10 output stage took a dump. BTW if you have a service manual for this unit please let me know..  I would love to make a copy. So... This one was on top of the pile... ok I plugged it in and nothing.. So I checked the fuses and they were both missing so I tossed in the two fuses and bang ...
Figure 1 Nomenclature Number TYPE H6L Teledyne / Part Number SLZ9145 National Stock Number 6610-00-960-7863 Boeing / 737 / Part Number I have had this VSI for about 1 year now and I couldn't sleep so I thought it would be good time to tackle this. This VSI (Figure 1)  was built for Boeing on a 737; Type H6L. This unit works on air pressure, so I will have to modify it.   THE DISASSEMBLY: The case is drawn aluminum with a cast bezel. We will dismantle the unit. Please pay close atte ...
Manufacture Part Number Miss Parker Hannifin 219-100-001 Innovative Solutions 9D-00659-1 SW 7H-659-79419 Manufacture & Part Numbers Table 1 I have had this Fuel Quantity Indicator  (Figure 1) for about 6 months or so. I have been stonewalled from ISI from getting any info. During Cockpit-Fest it was suggested that I cut the unit apart. Well this unit is solder sealed and I don't have a fire ring.. So out came my Multi-Max (Figure 8) and put a metal blade on it.. and well it took abo ...
Well here we are again, I know your going to ask me why am I making a post just for this dam cable??? The cable that had a short in it. Figure 1 THE ANALYSIS: As you may know back in February I said "It looks like there was a whisker shorting out the Blue.. GROAN: Ok the fix is painful. I have to cut down the shrink wrap and then the electrical tape and two layers of shrink wrap over the Blue it self." So being lazy I did repair the cable by opening the green layer and the re-soldered the blue ...
Well it has been a long time coming so here is the embedded software design. RSS block diagramFigure 1. The Plan: The Arduino must send and receive information asynchronously, via the byte serial USB host connection, on Port 1. This connection It must receive and respond to the RSS_IOP commands It must send data to the RSS_IOP when something changes Basicly you need 1 Arduino Mega per tuner. It has lots of Digital I/O, and its cheap! The protocol must be easy and expandable for all typ ...
The Plan Part 3: Ok the interface card is now wired up and hooked to a computer so we get on checking the software switch states. So I hooked my arduino to my radio interface, added the jumpers and plugged in the interface cable and then generated a truth table from that data (see figures 1,  2). int frac[] = {20, 5, 8, 2, 16, 4, 1, 9, 10, 18 };   int huns[20][2] = { {13, 0}, {9, 108},{11, 109}, {5, 110}, {27, 111}, {16, 112}, {30, 113}, {2, 114}, {23, 115}, {8, 116}, {28, 117}, ...
THE PLAN (Step 2):  Well the first thing we need is a piece of Vector Board, about 4" x 4"  or about 10 x 10 cm ( Do not buy any cheap crap off of ebay.. It must be FR-4, glass-epoxy ). Vector Board before for clean up Figure 1 I need cut 2 holes in the board about  2" x .5" (Figure 1), or you can use a DB25 punch if you are lucky enough to own one, $$$$.  I cut the two holes with my Dremel mult-tool, but it is very hard to control, I now have to clean it up, any way, with ...
THE ANALYSIS: The radio head C-3436A was used in the 1960's. It is used for both VOR and ILS. It has three (3) ARC connectors in the rear. I had built some cables for the unit a few ago but then never did anything with it.  So I need to test the RSS so I pulled out this unit. I am going use the term "Hacking" loosely as I am not going to damage the Control Set in any way.  Radio Control Set Figure 1 The Radio Control Set Opened for Testing Figure 2 Radio Control Set Interface F ...
So what am I supposed to say; A time ago, in a different space, and time, I started designing  a new canard aircraft, The Phoenix2000. In New Orleans before I move to Dallas, Tx so it has to be over 20 years ago. My original web site for it has a date of 1998 but that's about 10 years after the fact. I had built a dual channel, redundant FADEC, Full Authority Digital Engine Control, connected to FORD Taurus 3.0 engine. This means no mixture controls, you don't have to worry about things lik ...
Ouch... Where do I start.. Questions: How many power plants? ie Engines, APU, RAT, etc. Is you system going to be AC or DC based? What will be the prime voltage? 12, 24, or 48 volts Is there a ground power port? (makes life easy) etc... Well here is a overview of my airplane. You will notice that it is a twin. There are two alternators, and starters. You see  my alternators have had the diodes ripped out of them so the unit produces AC at 400Hz which is accomplished by applying a 40 ...
Ok I am going review some of the RSS as it is changing but in a good way.. Figure 1. RSS Block Diagram The RSS_IOP has a lot of jobs (review): Physical radios themselves. The radio's interface system  (arduino cards). Driving some intruments (flags, lights, etc) The interface to NavGroup intranet ( and decoding messages). Morse Code generator. FAA radio data base. (mySQL) Radio simulator. Line of sight calculations (between radios and aircraft) Crew audio station(s). Mov ...
Ok Now Lets all take a deep breath in an I will begin... Ok I have been dissatisfied my the state of flight simulation. It really bugged me that most planes have on than one seat, ie.. pilot, copilot, reo, nave, weapons, etc. Then I remembered a game called Star Trek that we played on the TCNJ, a computer network in NJ. each team had a captain, weapons, helm, engineering, science, transporters, and a few others that my old brain can't recall. BTW all this was played on a PCxt and the big 360 ...

Ok, it seems that we are back where we started from talking about the RSS_IOP. There have been so many changes that we may as well just start over. So now I can share with you the major data structures  from here forward. So lets get started. rss and tuner radio_xxxxx typedef enum _Radio_Types {   G3717,   C614L8,   G1981,   G3490,   G4214 }Radio_Types;       struct rss_s {   char * device_info;       & ...
