Well here is my VME rack on the right. This is my Test Rack, it really does not hold all the cards, I need another 2 cards. The CPU is working and has been tested. The blank slot in the bottom is for an IDE controller with the drive cable coming out of the front panel. Rotech STILL has not gotten back to me. Bummer. I only have one Mega that I was not using and it has the female headers soldered down. And I can not wire wrap to it, therefore I have no way of connecting my Arduino Mega to my DB- ...

Back to The Project14 homepage Project14 Home Monthly Themes Monthly Theme Poll   Ok so time is ticking on by so I am reducing the complexity by only using an Arduino Mega R3 with two 16 bit i2C expanders. This will achieve my short-term goals of 25 x 25 matrix with the flying probe. This will not be client/server, nor use configurati ...
Ok, so the work continues on three fronts. BBC microbit no guts no glory. Underpowered, Lack of any real I/O, Banana Plugs that don't fit into the holes - Almost Trash. Arduino, found the code, for a self-contained cable tester, but has no flying probe and no easy configuration changes. VME possibility of a finished client. Trying to decide to run Intel or Sun Sparc. Found a Zycom DID 6U board with 64 bits of random  Digital I/O, Rotec gmbh seems like they just want to ignore me. Maybe ...
I got home on this past Friday evening, having a really bad day of "STUPID PEOPLE" at my VA Hospital in Dallas, and found a package outside my door. After I opened it I found a T-shirt, silver antistatic bag with something in it, batteries, and battery holder. Well after poking around in the bag I couldn't realize I got it for this entry. And after a while, the lights came on. My VME rack system is still a ways away, so I will use this SBC to do the lifting by substituting TI 2x sixteen-bit i2C ...
Last night I woke up about 4 AM and realized that I don't have to use any Arduino(s) for the Cable Tester.   I remembered that I had picked up a VME chassis with a bunch of Rotec I/O cards. The final configuration will  be 256 channels (half input and half output)  So here what I'm going to do. Parts: 32 channel Output Card(s) DIG 32-Ok (I have 4 of them) 32 channel Input Card(s) DIG 32-IS (need 4 and I have 6 of them) Interface Cables RTC-K-049/4M (need 8 and I have 10 of them.) ...

Some cables are downright ugly! And the worst ones don't have any pinout. Want List (Dream Big): Hardware Expandable /  Software Ex ...
