|
| Hello world, To richardv@abac.com, I am eagerly awaiting your results. To joe.doubek@privy.com, I'll keep you posted.

| | | | | Re: dual servos
|
| I'm a newbie at this, but I just read yesterday on a web page that servos want a signal (20 ms = ?? degrees) every 50 milliseconds or so, and if you stop sending the signal, they "go limp" and don't "hold" position tightly, but are deenergized and (...)

| | | | | capacitor question
|
| I was just wondering about this - are you supposed to heatsink capacitors when soldering? My gut feeling says "no", except that my ECE TA seems to disagree. Any thoughts on this? (Sorry, this doesn't have too much to do with the handy board - (...) (28 years ago, 16-Jan-97, to lugnet.robotics.handyboard)

|
| [problem 1: voltage on motor chips when no motor voltage applied] This is normal, because the motor chip INPUTS have +5v signals on them. These signals "bleed" into the motor chip power supplies. This isn't dangerous, but it isn't particularly good (...) (28 years ago, 16-Jan-97, to lugnet.robotics.handyboard)

|
| I located a 9.6 volt 700 or 900 mah battery pack at Radio Shack and the one on the parts list is just 500 mah. My question is, will the charging circuit work ok with either of the above battery packs from Radio Shack? Thanks Bill Rose (28 years ago, 16-Jan-97, to lugnet.robotics.handyboard)
