Just checked both three (3) wire cables and of of the two (2) cables have a bad ground (black) crimp. Will try on Monday, when I buy another cable, and fingers crossed that was the problem.

That would explain the problem.

In order to work five of the six cables need to make good contact:

  1. 3.3v - Pin 1
    Without this the PicoBorg Reverse will not power up
  2. GND - pin 6
    Without this most things will not work, the Raspberry Pi might not even boot
  3. 5v - Pin 2 or 4
    Without this the Raspberry Pi will not boot up and the PicoBorg Reverse will not power up
  4. SDA - pin 3
    Without this you will see the error you currently have
  5. SCL - pin 5
    Without this you will see the error you currently have

Given your error and cable check I suspect that the SCL line has not made a good connection.
This upsets the I2C communications and means that the Raspberry Pi cannot talk to the PicoBorg Reverse.

A replacement cable should solve the problem.

Thank you for the quick response, quite excited to swap out the cable on Monday and fire up DiddyBorg.
Best regards,

I am not seeing GUI after remote login (HTML).
Remote display shows:
Loading PicoBorg Reverse on bus 1, address 44
Found PicoBorg Reverse at 44
PicoBorg Reverse loaded on bus 1
Setup camera
Setup the stream processing thread
Wait ...
Start the stream using the video port
Setup the watchdog
Press CTRL+C to terminate the web-server

Could this be a version issue? I have attached the diddyWeb.py code.
Any help would be appreciated.
Thank you,
-Bob

It looks like some of the lines have been split in the copy you have uploaded, starting from line 307.
I am not sure if this is a problem, but it might be worth fixing.

Are you using the correct IP address for the DiddyBorg?
You should be able to get the IP address using the command: hostname -I

Working now, i am in debug mode and using AC power and connected battery pack; however, not snapped. Once i made sure both + & - were coupled, it began to work, now i need to test at home as work has way too much 2.4 GHz traffic (250+ devices).

Wish you had a distributor in the United States, as I had to have a friend from UK purchase and mail to me.

You are missing out on revenue without USA distribution. I'd be glad to be your distributor in the states.
Thank you,
-Bob
