Greetings all from Vancouver Island.
Happy New Year 2015.
Been watching the progress of this OPENROV project for some time.
Early last year (2014)started to gather parts for a winter project build.
Bought most parts separate however purchased the Controller Board V2.6 from OPENROV Store.
Early last year could not purchase a BBB anywhere for love nor money. Finally purchased one in Vancouver and took delivery in the summer.
Started to assembly mid December 2014.
I am cautious, knowing that sm components can be easily blown by static and/or mishandling.
I assemble components then test before going to the next stage.
Sequence so far;
Received BBB and loaded the image on sd via desktop, and placed in BBB, connected camera and powered up via usb into my desk top Win7 computer.
Went through BBB website and loaded drives (64bit) and displayed the Cockpit, works fine and repeats.
Disassembled the Tenda adapters (V1), powered both up using voltage regulator, wired a tether between them and tested to see if I could get communication between my router and laptop.
After getting the IP address correct, things worked fine.
Then I connected the BBB with the camera to one of the Tenda Adapters and connected the tether, then connected to the surface Tenda adapter then to laptop. Worked fine, laptop displayed cockpit with image from camera. So far so good!
Next stage to put Tenda Adapter on the Controller Board. Made modifications to the Board so as to accommodate the V1 adapter. Also at this stage soldered the 3 esc in place.
Wired the tether into 18 & 19 on J5 and connected 12v power supply to 4&7 grounds and 5&6/ 12volts.
Switched the surface adapter on , measured voltage at 18&19 on J5, 4.73volts.
On the controller board LED 1 green & LED2red came on. (So the tether voltage switches the power on the controller board.)
Checked voltages on J9 and J10, where the Tenda Adapter plugs in.(without adapter plugged in at this point)
Voltage on J9 4.98volts
voltage on J10 4.73volts.
I then switched off the surface adapter, thus powering down the controller board, plugged in the adapter board and switched the surface adapter on.
Led 1green came on, & Led 2red though dim at first came on the bright, no lights on the Tenda adapter board.
Measured the voltages again on J9 & J10...this is where I am flummoxed
J10 reads 4.73volts (great)
J9 the voltage has dropped down to 1.23 to 1.27.....what is going on???
Has any one else experienced this?
if so what is the solution
No BBB mounted at this time, waiting till I remedy the adapter voltages on J9 before I continue.
