Looks like it will work, made 24.
Now to get the Bubble-Licious.

Someone else attached the ribbon cable.  smiley-zipper

I don't think you are going to make money from this when it is so simple to make your own using copper clad board.
I would never use your method.


303  Using Arduino / General Electronics / Re: Why connect arduino GND and power supply 0V? on: August 06, 2014, 05:03:52 pm
In your circuit you must have a common ground.
You could use an opto isolator ( google it) then you would not need the common ground.

It's a simple board, I have been caught on simple boards before  smiley-sweat
This is what I am going to try, what do you think?

One row of pins on the wire wrap socket is going to be used as one row for the IDC connector.

Have you seen 24 pin IDC connectors? I have lots of 26 pin which would work, just won't use 2 pins
305  Using Arduino / General Electronics / Re: Bobuino2 Must have on: August 06, 2014, 12:51:53 pm
Your version is very much better.

I am going to try the DIP to 26 pin IDC board adapter, for ribbon cable to the Bubble-Licious

6-32
#6 screw 32 threads per inch
#6 = 0.1380" (3.5052 mm)

Thanks Bob:
I am checking out my new Bobuino2s.  
http://www.crossroadsfencing.com/BobuinoRev17/

No more memory or ram limitations.
Lots of I/O, a RTC, RS232, level shifting, bread board area, and comes with SD card stuff.

You got me on the Comm1 jumpers but it only took me 30 seconds to pull the shunts.

Even comes with a 5 minute air supply for underwater work smiley-wink
I was just kidding about the center LED being off shade  smiley

I highly recommend the Bobuino2 PCB to those of you who need a UNO comparable, all in one product with lots of memory.

P.S.  We in Canada like 6-32 mounting  holes for the stand-offs, but I did have some 4-40s so I guess it's OK.


308  Using Arduino / Displays / Re: New "Bubble" display! on: August 04, 2014, 03:47:26 pm
Even though the display pins are relatively long, I like the idea of using Wire Wrap sockets as they can be mounted on the outside of a front panel.
Socket pins are long enough to go through the thickest plastic panel.
With the female header idea, you can simply unplug the PCB from the socket pins if needed.

we'll get the wires secured
Grey wire wrap wire will be less obvious.

To me, it comes down to the things I have right now, on hand.
I have used both equally well.

I like that the dimensions of the 8 digit display are only 1.25" by 0.3" with only 5 wires !

311  Using Arduino / Displays / Re: New "Bubble" display! on: August 03, 2014, 07:57:03 pm
Here is an image to front panel mounting of the displays.

Show us a drawing of your circuit with labeled values for components.
Show us a picture of your wiring.
313  Using Arduino / LEDs and Multiplexing / Re: 9x9x9 LED cube on: August 03, 2014, 02:43:12 pm
I think the very middle LED is a bit off shade.
Please replace it.
 smiley-draw

Better get a plexi glass box around this soon !
314  Using Arduino / Displays / Re: New "Bubble" display! on: August 02, 2014, 09:16:22 pm
No he is wrong.
I don't want 30, I want 35 (if he lets me).

These will be great as a very small foot print 8 digit panel mount displays.

See the duty cycle section.
Other great reading here.
