| | How to get digital outputs from the handyboard???...???
|
|
hi everyone, i have been trying for the past few days to get digital outputs from the board but with no success. i have been trying to get digitals outputs from the SPI's pins (J6). i have poke to make the port as output port. but the problem now is (...)

| | Servos for the miniboard
|
|
I would like to use a servo to operate the throttle of a small gas engine. I am planning on using the miniboard to control the servo. Are there any brands to avoid? Are there any brands that are far better than the rest? Will just about any RC servo (...) (26 years ago, 10-Dec-98, to lugnet.robotics.handyboard)

| | Re: Stepper vs DC
|
|
It depends. if you are looking for higher top speed and more torque using less power, DC may be the way to go. If you want accuracy but don't want to deal with shaft encoders and the code overhead needed to precisely control and monitor your DC (...) (26 years ago, 10-Dec-98, to lugnet.robotics.handyboard)

| | stepper motors from 5 1/4 drives
|
|
Okay, another newbie question: What do I need to take out of the 5 1/4 drive, other than the motor to get this to work? Also, what about drivers for the same? Anyplace I can get more info on this? I have a bunch of old drives laying around. thanks (...) (26 years ago, 10-Dec-98, to lugnet.robotics.handyboard)

(...) Actually, steppers do have some advantages. 1) If you do not have encoders on DC gearhead motors (or wheels, etc) they are notoriously hard to position accurately. Steppers can be controlled very accurately. Most servo motors cannot rotate (...) (26 years ago, 10-Dec-98, to lugnet.robotics.handyboard)

Bastiaan: I wanted to suggest that you investigate the Ham Radio community. Some search words to help get you started include PACKET and ARRL. The first is one of the digital communications protocalls used in Ham Radio, and the second is an (...) (26 years ago, 10-Dec-98, to lugnet.robotics.handyboard)

If the data tx/rx modules can't handle TTL levels is there any reason to have the interface board at the PC end ?, why not replace the serial cable going to the PC with the rx/tx modules ?. Surely this should work. John (26 years ago, 10-Dec-98, to lugnet.robotics.handyboard)
