(...) I just noticed that the Polaroid Specs say that the transducer pulse current is 2 A. 100mA idle. Since it was mentioned previously that the HB's VR is rated for 1 Amp, how would this affect the sonar? Perhaps whatever is left of the 1A (...)

| | Interfacing PICs and Basic Stamps to Handy
|
|
Since (I think) it is fairly easy to interface the HC11's SPI interface to a PIC/Basic Stamp I & II this is probably easier than creating a custom RS-232 interface. Has anyone done anything like this? Sean R. Cunningham (28 years ago, 28-May-96, to lugnet.robotics.handyboard)

Hi, I am trying to install the polaroid 6500. I use the schematics I found with the sonar.c file at this site. It doesn't work, I dont understand the Motor power connection why does it have 4 pins ? One motor only uses 3 pins ? I think the sonar (...) (28 years ago, 26-May-96, to lugnet.robotics.handyboard)

(...) Randy, I'm having trouble making the TOC2 work with Pcode_hb, something trashes the output whether I disable IR-Xmit or not. Do I need a new Pcode in order to divert TOC2 to my own use? I'm treating OC2 the same as I treat OC3, but only OC3 (...) (28 years ago, 25-May-96, to lugnet.robotics.handyboard)

(...) All system power, incl. motor pwr, already runs through the existing polyswitch. They're not too fast, so I'm not sure if they'll save you. the motor chips do have over-current protection of their own, though it has been known to fail from (...)

| | Fuse on motor power cables

My current robot platform is a hacked toy and does not have ideal motors. I am concerned about toasting my motor driver chips. Can I put a polyswitch fuse in series in the motor lines to protect against this? They don't seem to be polarity (...) (28 years ago, 24-May-96, to lugnet.robotics.handyboard)

Hi all, I have not worked with the handy baord much yet but I also feel that it would be nice to have a few more digital i/o ports available. I guess that is short, sweet, and to the point. sherman@plains (28 years ago, 23-May-96, to lugnet.robotics.handyboard)
