Hi every one..I am new to this group!!! I need some help, could any one tell me how to do the speed control of dc servomotor with digital encoder using pic...
Believe it or not, the problem was with the plane, not the operator. The tail is attached to the fuselage with a carbon fiber tube and this had came loose. I...
Tom, why don't you try SecureDigital cards? They can be driven using SPI, actually I am doing it using an IsoPod, but it is pretty easy if you have SPI in...
I've been wanting to hook up to my parallel port for years. I'm worried that I will fry something. What documents should I look at that will give me...

Krish, Your question is a little non-specific, but this might get you started... You will need to use the CCP feature to capture the encoder pulses, then ...

Hi Giuseppe, Can you give us some more information about how you interfaced the SD cards to a controller? Can you give some examples with a Bsic Stamp or a...
When you're running a serial line straight out of the sending device, they usually run the signal at 5V or less. If you go the 485 route, the signal gets sent...
John, it is not *so* easy, you are right. First of all, I didn't ever used a SPI port, so bear with me. Isopod has hardware SPI (like pic and others, about...
I purchased the JVC LIon batteries you recommended in an earlier SRS meeting, and also got the CH-830 DC/DC charger module. Have had great fun with the setup...

I have been looking for a coporate sponsor because I have very little budget (i.e. what I find in the cushions of the couch) for robotics. I have been asked by...
I dunno. ... From: Karl Lunt [mailto:karllunt@...] ... If you don't remove the PCB on these batteries, do they still charge (and discharge) properly,...

If you get a chance look up Steve Jobs demonstrating a Mac laptop when the lithium battery decides to go exothermic do so. It is quite an interesting show :) ...
Some very important corrections. RS485 does not in fact use positive and negative voltages. RS485 uses differential voltages riding on a common mode carrier...
Sorry, it was a couple of years ago on one of the Apple Inc pages. I don't think they would keep it around for posterity :) But I thought you may be able to...
The RS485 standard is a little more robust than just a higher voltage. It uses a differential line transciever to increase the reliability. Basically, two...
Hello, I am currently attempting to link my Motor Mind C to my BS2p40. I have written the program that is attached bellow to run the Motor mind. However, I...
Gabe, for one thing, you cannot issue the GOSUB command without a corresponding RETURN statement. Your example, as shown here, will blow the BS2 stack after a...

Rather than considering the ripple to be parasitic, could you count the ripple pulses to use the motor as if it were an encoder? Perhaps the biggest problems...
