This is a visual inspection to see what I'm up against. So without delay lets get into it. Disassembly: First remove the foil around the rear of the bezel. Unthread the large black ring on the back of the connector. There is a large O-ring that will come out after the back has been removed. The RMI internally is divided into six sections.  I have described them from Front Face to the Rear Connector.  This is just to inspect the unit and see what I will have to plan for, as of yet I st ...
Ok, So you think you have a library, what maybe a dozen or so books lying and a few pdfs around? Well at the last big count I was well over 1000, some are still in boxes, and some lost forever. So you really should organize it. I Have a large collection of various book, Fiction (first editions of Robert Ludlam and Isaac Asimov), Cooking Books, Lots of Movies, DIY shows, well you get the idea. So you need to organize it. Your choices are very limited: Dewy (like in your local and maybe your scho ...
Well, here I am with another power supply. This time it is a venerable Lambda brick. Manufacture Lambda Model LM B-15 Serial Number D27233 Voltage Output 15vdc +/- 5% Output Current 80watts. I got this beast a  garage sale and for only 12 bucks now let us hope its really not just a brick. So the first thing I did was attack it with my tools, pulled it apart and gave it a good brushing to get rid of the dirt, webs, and just crud. I have included some pretty snaps, and I know how you lov ...
Well here we are again back at the MPCD this seems like  "The Neverending Story", oh well here goes. I had originally specified the MAX6955 LED display driver IC.  A problem came up and it appeared to only support Charlieplexing,  a technique to use fewer wires to drive your LEDs. Background: Just to keep you all up to date I have included the links to the other blogs in this series: Hacking the Navigation Computer Display, Software Overview: Nav IOP. New Analysis: As I have prev ...

I have talked about the Fuel load Indicator twice before, first here and then here. So here is the hardware design and its analysis. Analysis:  In my last blog I noted that between the display and the switches I am using about 25 pins + ground and power. So to recap here are the pins: I have added a second table which shows the I/O connections. The reason that I chose the STM32 was for its size. It can easily fit inside the enclosure (approximately 7cm square). The Plan: The Hardware: Si ...
Dang. I can find my go to WireWrap gun, a Gardner Denver 27100AB2.  So I know somewhere I had a few laying around (things you NEVER get rid of!). So after digging in my warehouse for a while I found three semi-dead guns and one with a bit and sleeve. I did not like the cable as it was badly frayed and the index was not working. So here what to do ( See the pretty pictures below; as I know you all like them ): Find and remove 6 Allen cap screws. Remove upper case and look around An aha m ...
Ok, you just installed Debian 9.5 with the Cinnamon Desktop. Now, what you can run a command with sudo it bitches and says your not in the sudoers file. So let's fix that first: open a root terminal,  so and it should look like this: harrison@whirlwind:# Now, let's add ourselves to the sudoers file. Please note sudoers is -r--r-- this means it is read-only and we have to change it to -rw----- ok? harrison@whirlwind:# cd /etc harrison@whirlwind:#  ls -l  sudoers -r--r----- 1 root r ...
It took a while, on Dec 25, 2014, I showed you a picture of my bashed Lambda power supply. This must of happened in moving. So with the advent of a few "Maker Spaces" and a brand new large lab at UTA (Univesity of Texas at Arlington) and a nice hydraulic press, I should be  able to effect repairs to the front panel and make it well almost new but I will still have problems with the meter lens as I have not found a donner. This supply has been my go-to supply for a lot of years and would lik ...
OK, so far I have shown you what you need, and what not to do, and never dos and just bad things that we tend not to do as programmers. Now I'm going to so you a program side-by-side Arduino vs eclipse using ANSI C.   Arduino eclipse /* C-3436A * *  C. Harrison Aug 30, 2014 Creation * */   #include "C3436A.h"   void setup(){   void modes();   Serial.begin(19200);   Serial.println("C-3436A awake");   void init(); }  void loop(){   int i;   // ...
Ok now the fun stuff. Now we can do something..  We still have a small mess to clean up now. It's the Arduino's Libraries. They are quite a mess so here is what we have to do The Arduino's IDE wants only to see two main functions: setup()  Setup is where you do something once. loop()  Loop is just that a loop. Now while in the loop() function you may call other functions. A function is nothing more than a subroutine, with a defined argument list, or none, and some return type o ...
Well my Linksys WRT300N Router was rattling.  Had something broken loose? I needed to find out. So here are the steps to take the router thing apart. along with pretty pictures that you guys really like. Turn the router on its back and lift and rotate the four feet out of the way. Gently pry the blue bottom plate off. (Go in from the front and use very small flat blade screwdriver) Gently pry the translucent bezel off. There are 4 clips holding it in. Turn the router right side up and ...
Ok well here is my Universal ATR box known as ATR.poly. This design covers both master and slave units. First, let me say that the Sterilite model #1961 has 8.75" x 5" of usable space for my baseboard. So here are my design rules: (1) All components will be plugged into the baseboard;  (2) There will be only one copper for both master and slave units; (3) The ATR.poly boxes are standardized. (4) The main components are plugged in so that means there are Female Headers with solder-tails moun ...
So I figured out what I need for the drill press. A nice sturdy X-Y table that I can move around manually and of course electrically. The bed should be about 12" square. So far this is just a pipe dream, but just maybe. DESIGN:   First I'll need two lengths of V-Rail, Aluminum 6063-T5, each one about 500mm long. Since I have a much smaller work surface I will have to get creative. I really only need to drill 5 holes at a time for aircraft instruments. Five inches is the largest circle ...
Wire, wire, wire; So here we go I have to straighten this mess up. The Problem: I have lots of Arduinos all over, and since I embraced NASA's EADIN Lite RS485 protocols for my RSS, and Now the Joystick, Throttles, etc. the hardware keeps piling up. A Solution: I should do this like we do in aircraft, and that is to use ATR boxes (see note 1), the problem is that now its big bucks. And then the rack, not to mention the connectors. Sticker Shock.  There has to be a cheaper way.  Hey, ...
