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-...
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 diagr...
So why do I need a version 3? Version 2, takes forever to print and the printers are in the library (still closed). So that leaves me to go look for a better solution.
Along comes The Container Store. They have an acrylic box (Kid's Shoe Box, clear a...
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, but since I am using an Arduino I ne...
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 c...
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. ...
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 s...
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 i...
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 i...
I have been waiting a few months for this little gem. So without further ado, let us get to the pictures
1 The Box?
2. Instructions?
3. Raspberry PI 4
4. 16GB Module with OS
5. A little plastic case for the thing.
6. Power Sup...
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 ...
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...
This subsystem is part of the Pilot Controls (node id 100) consisting of the following subsystems. Inter-subsystem is handled by CAN.Side StickThrottleLanding Gear Lever lamps and sensorsRudder Pedals with differential braking.The subsystem consists ...
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 h...
I find my parts in a relational database. Why a DB? Well I have a lot of parts, everything from hardware, printed parts, and electronics, to avionics. Now, this is a pain. So there are a few tables that need to be created Info, Manufac, Category, and...
In this post, I will be talking about my switches which are done with an interrupt on Arduino Mega's pin#2, and just to keep my head on straight the interrupt service routine's name is isr2. First, let me digress. The Fuel Load Indicator has two (2) ...
These three images are from "Embed With Elliot: Debounce Your Noisy Buttons"
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...

I have blogged about the Navigation Computer Display's Keyboard here. I was moving a 6821 PIA to its resting place and checked my Databooks where I found a pdf copy of the 6800 application manual. where they had a 4x4 keyboard interface. It was b...
This is now round two. last night I wondered if I popped the MCP23017 or, is the scanner software bad? So the first this I did was to stick an MCP2327 on a breadboard and ran the scanner. It still said No I2C address found. As I relooked at the...
Well, I am working to get the Indicator done today or tomorrow, the slight tremors in my hands make Wire-Wrap a real pain. I will not get to a point where this will be buttoned up, as there will be a lot of jumpers! I also have to trim down the inter...
This picture on the left is just to remind you all of what I am trying to get working. Each HDSP-2131 display has 24 pins that give you 48 pins to deal with. Now let us complicate the issue the pins come out on a 30-pin connector of which 4 are...
Well, for starters there are problems with the Arduino CAN bus library, as ANY node in the system can be a master or a slave. Currently, the Arduino CAN supports a SLAVE - MASTER, relationship. On the MCP2515_CAN module, you have the following connec...
