This is a how-to I build a typical node, this will show you my methodology. You will need to gather your goodies. In this case, I will need the following: ( this is a complication of the Info, Manufac, Category tables the only thing not included is the Quantity column.)   Product Name Quan My Part Number Manufacture Part Number Enclosure, Polycarb 1 104-00001-00 Nam Ngai Hong 605RS Arduino Mega 1 35-00002-00 Arduino Mega 256 R3 "    "  Mount 1 95-00001-00 Arvan Meg ...
I have talked about this radio back in the day. Please See NexGen Simulator Blog Index iii. You will see 13 prior entries. So why 14? This post is using my current schematic for the wiring which will do the decoding very straightforward.  The C-3426A schematics and pinouts are included in  TM 11-5826-215-35, "Field and Depot Maintenance Manual Receiving Set Radio AN/ARN-30D", (page 15). As you can see below the data from the head is from ARC-158115 (19pins) which is connected to DB25.1 ...
Ok, what is a protocol converter, and why do I need one? Well, a CANaerospace frame is defined as an 8-byte message with the first four (4) bytes comprising the header and the remaining four (4) bytes as Message Data which is type-specific (see diagrams). The codes for the header fields are listed in a book by NASA  AGATE data bus / Michael Stock Slight Systems, Interface Specifications for Airborne CAN Applications or a good overview in a slide show presentation. Since the two services ...
I have been down this road before but now I have the final solution. I found it in my old Motorola M6800 Applications Handbook, section 5-1.1.2 NonEncoded Keyboards. It used a PIA or Peripheral Interface Adapter, since I am using an Arduino I don't need the PIA.  But I will replace it with an I2C 16-bit I/O expander, MCP23017. As you can see I drive the data lines Data-0, 4 with a high. When there is no key closure nothing happens but if a key is pressed 1) the active line is seen on its co ...
I have been working on my C-3436A radio for quite a while after it worked I took it apart to install it in its new home and I could never get the damn thing to work again.  So with way too much time on my hands, I decided to ring out the damn cable once and for all.  Now I can report the job is done. KiCad helped me see my mistakes. This cable is really two cables each terminated with DB-25Ms at one end and ARC connectors at the other. One cable was just DB-25M to a 19 pin ARC connecto ...
Well, a lot of folks have written about the SN74HC595x as an 8-bit shift register. The major use is to expand ports in the Arduino. (image 1) This is the classic way to expand your Arduino for 8 more ports, without resorting  I2C or CANbus.  But what if you need 16-bits as I do? But as you can on the left see by connecting the QH' output of the first shift-register to SER input of the second shift register you can end up with a 16-bit shift register. By adding other shift-registers yo ...
STATEMENT:  I have a problem refreshing, the  20 odd displays in less than 1/4 second each, which would let them seem that there all bright, but they will be dim, to begin with. So multiplexing is now out for the 7 segment displays, but I still will multiplex the four 16 segment displays. SOLUTION: I found an IC that handles eight 7-segment displays and it has a built-in SPI interface. The device is a MAX-7221 which will give me a solution for my problem. As you can see in the block d ...
Well, here we are back again, with the Fuel Load Meter. This thing has given me nothing but grief. So I am going to take another whack at it. I still have to make sure that the wiring is correct. and then write the code. The problem I was/am having is the 30 pin connector that goes to the display.  This is a Never-Ending-Story not to be confused with the movie with the same name (German: Die Unendliche Geschichte). It seems like you take one step forward and two or three backward. This tim ...
This unit is most likely made by YIHUA.  The 853D is broken down into three functional blocks. SMD Rework Wand. This has a digital temperature control and has interchangeable tips. Solder Station Wand. This has a digital temperature control and it is removable via a 5-pin Din Plug. (I intend to buy a solder removal gun with vacuum) Power Supply (0-15vdc) with Digital Voltage Readout but set with a potentiometer. It also has an analog current meter. The Test Switch has two positions: Th ...
Hi Gang, I just compted a schematic pinout for the Mega, Enjoy If you want to use it you can find it at www.NexGen-Simuattion.com  give me a day or two I just erased it but you still can use it. open in Gimp REMOVE BLACL Vertical and Horizontal lines export it as a BMP. and import it with your symbol edittor. ~~Cris ...
OK, I have worked the past few days on getting the RED lamp wiring finished. I have decided to get my 1Hz blink rate from a NE555 timer, instead of messing about with Arduino Timers or delay()! The Red Lamp can be 24vdc or 5vdc. The only thing that I am concerned about would be 25vdc and its ground which really needs to be at the logical ground but as Murphy Laws, state that anything that can happen will, so I might make a rev to this sheet to remove the transistor driver and replace them with a ...
This subsystem is part of the Pilot Controls (node id 100) consisting of the following subsystems. Inter-subsystem is handled by CAN. Side Stick Throttle Landing Gear Lever lamps and sensors Rudder Pedals with differential braking. The subsystem consists of the following: Landing Gear Control Lever (CANid: 1175) 3 Red Indicators (CANid: 1400, 1, 2 ) 3 Green Indicators (CANid: 1403, 4, 5) WOW, Weight on Wheels, (CANid: 1176)  this sensor, prevents Landing Gear retraction while on the ...
Well, as you all know I love junk and test equipment even if I don't have a use for it now. Maybe 4 years ago I was at a garage sale where they were selling a lot of IC's etc.  He said, "Would you like a power meter?" I think he gave it to me for about 5 bucks and he had a pile of them. It did not have a cable or a probe. So I thought how hard will it be to build a probe for this thing?? So I went looking and here is what I found. Hewlett Packard Jurnal June 1915...Digital Power Meter Of ...
Header 1   In this post, I will be talking about my switches which are done with an interrupt on Arduino Mega's pin#2, and just of keeping my head on straight the interrupt service routines name is isr2. First, let me digress. The Fuel Load Indicator has two (2) switches and each has two (2) positions for a total of four (4) switch selections. So how do I generate the interrupt? One way is to connect the four wires (a, b, c, d) to the Arduino and then use a quad 2-input or-gate, SN74LS32. ...
Why do I say aftermath? Well to put it simply it might have been a bit of an overreach.  I spent more than a few days trying in vain to get the display board pins identified.  So here are some videos for the Fuel Load Indicator.  First up are the function switches. These three images are  from  "Embed With Elliot: Debounce Your Noisy Buttons"   There is one more board and that is the Signal Conditioner. This is a small board that connects to the switches and ...
