Ok this is more of a bather than a post. Buckle up the ride will not be smooth! The US National Highway Traffic Safety Administration (NHTSA) in April 8, 2005 said it should be on all cars by 2008 and now trucks.. ok thats cool. Commercial Aircraft have had them for years BC (Before Cars) .. But in between those 2 camps there is a huge Black Hole. Whatever  you wish to call the tires, ie: rubber, skins, sneakers, and others. Tires are the most ignored, or understood part of your plane. You ...
Function Generator Image 1 This is one of thoughs things that just comes along. It is a B&K Precision 3010 Function Generator, it was 5 bucks at the local Goodwill. It did not have a power cord set and I'm never going to find one (image 2). Power Plug not NEMA Image 2 Hack #1 Image 3 Hack #2 Image 4 This connector is not the standard oval, its smaller. Over time I have seen some terrible hacks, good ol' Southern Engineering, Rigging, etc (please see images 3 and 4). But I'm ge ...
You had that pile of transistors and you didn't know if they worked? Well I know I have... So today while rummaging around Before we started Image 1 in my local pawn shop I spoted this old tester in one of the stores bins. I was labled in Spanish no less.  It was marked $14.95, but I got it for 5 bucks.. When I opened it up, I found out was rather crude, and nothing to write home about.   The Guts No Blood yet Image 2 The Schematic Image 3   THE PLAN: I would like to have ...
Ok what in the world of Microsoft and Windows and Linux is NFS and why do I need it... Really I'm very happy with SMB or CIFS,  or Samba (reversed engineered SMB) so why change to NFS?? SMB is a kludge, its what you see is maybe what you get. and it really is not Open... CIFS is single threaded which makes it SLOW! and NFS just works, and it's dam fast!!   History: NFS is a distributed file system protocol originally developed by Sun Microsystems in 1984, allowing a user on a ...
Well it looks like I found a working 5 volt supply that works!   It's a Lambda LXS-A-5-0V (a brick, and this is stock photo off the web)..  So I wanted to test the the power supply. So I grabbed  the Fuel Load Indicator, that I tore apart in my blog post NexGen: Hacking the Fuel Load Indicator. I hooked my +5 to pin 16 of the display and Ground on pin 17 and I got the following: Manufacturer: LAMBDA Model Number: LXS-A-5-0V Output Voltage: 0 - 5 vdc Output Current: 4 amps ...
I guess I am just a glutton for punishment, so my next victim is an HP Harrison 6284A power supply.  It seems in good shape so it should have been a safe bet. The only thing that I saw wrong was that the power switch lamp and push/lens cap was missing not a big deal as a small screwdriver will turn it on... So I hooked it up and put a meter on it.. The output is adjustable.  The meter pegged so I thought I was just on the wrong scale, fickle is the equipment god, and as I changed the s ...
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 ...
