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, ...

I just salvaged this little jewel from an Aiwa AV-X120 Stereo Receiver, that sorta got crushed.  The receiver I had found at the Goodwill for 5 bucks. What I wanted were the transformer and monolithic power amplifiers. Along the way, the volume control got tossed in the to-be-saved tub. Now a few months later,  I uncovered it again and the light went on.  Now I need to do my homework before I can use this in NexGen's RSS-IOP audio controls (it will be buried in one of the boxes).& ...
This is a really nice find at my local pawn shop. I uncovered this jewel in the Dollar box.  It was sticking badly. It really needed a good cleaning. It was a Starrett model 436-1.  I retracted the spindle into the sleeve and then removing it. by continuingly rotating the thimble counter-clockwise. This took a few tries but finally separated it.  I used a lightweight oil and a new Scotch-Brite® Stainless Steel Scrubbing Pad to clean the spindle. I had to repeatably fully inse ...

You know you get the dumb look on your face and is this damn thing working? Ethernet has activity indicators, you know the two lights on the RJ45 socket. Well, we can do the same for Serial Ports remember that Arduino's are only 2 pins (rx and tx).  Factoid: I hate messing with RS232 connectors. So where does it say that You must use DB-9/15/25? really nowhere. So grab you an RJ45 Breakout Socket without magnetics from the web. So we have four (4) pairs to play with. BTW pairs are a goo ...
Stock Image of the Scroll Saw Image 1 Well ok,  this is kind of backward... I don't have a good picture of what it looked like before I started with its resurrection. I found this Moto-Shop 571-4 (image 1 is a web image. Mine was dirtier)  at the local Goodwill (they sell stuff by the pound). It cost me a big 5bucks, and I thought that it would be good to use to cut my instrument panel. When I first plugged it in, I heard the motor hum and the bar kind of move.. This meant the moto ...
This is a necessary evil of any lab, workshop. I have needed one for quite awhile. When I moved from New Jersey to in 1979 I left my floor unit with my bother. Imported yes, but well done, and morse taper removable chuck. So the other day Harbor Freight was having a Black something Sale and with the coupons and what not I pick this one up for about 40 bucks. Major Components Drill motor unit Drill Plate Base Column I did not really expect much. I opened the box, nothing missing ...
Ok for me this is off topic but it is something that I am meddling about with. I picked up a dead Blu-ray player with no drive, but it does have a nice RJ-45 and an internal WiFi transceiver sticking out of the back, and a neet black front panel. Now as it happens the thing also is written in Java. THE PLAN: is to make it see my NFS mounted library, and to play them like locally mounted media. THE ANALYSIS: I have included my configuration, see the table below. Checking around I found out th ...
The RSS has been well sort of like a trial by fire. Well to put it bluntly it was nuts, with too many moving parts.!! Sort of like an old Rube Goldberg Machine. What I needed was a better way. Enter Java. Java has been around for more than a decade by now, it 'is concurrent, class-based, object-oriented, and specifically designed to have as few implementation dependencies as possible' - Wikipedia. When It was first introduced I grabbed a book, and I liked what I saw, and over the years writing ...
