| Actually Jake, I'm having a similar problem right now, with regard to loss of RAM capabilities. I've been testing a new Polaroid 6500 sonar (which now works!) on the HB and I've got it hooked up through the exp. board. I tried to run a simple (...)

|
| Bob: If you have major problems with the handyboard you would have better luck with a logic analyzer than with an oscilloscope, however, I have build two handy boards successfully without any of these tools straight out of the box.

| | | | | Required tools for assembly
|
| Can somebody please tell if it is absolutely necessary to have an oscilliscope for the assembly of and H board? If so, what are my INEXPENSIVE options/suppliers?

| Hi I use a Polaroid sonar ranging modul with the HB and the expansionboard. It all went well, but by mistake i put the digital in from J12 to a digital out. Since then i get the result -1 and the sonar isn't clicking. I've tried with another sonar (...) (27 years ago, 18-Mar-00, to lugnet.robotics.handyboard)
