  IC with Botboard 2
 
Does anyone have experience modifying IC for use with the BotBoard 2? (i.e., changing address for the beeper, etc.) I have been able to get IC to download and run, but I would like to customize it to fit the hardward on the BB2. On a related note, (...)

  Servo Question - Cirrus
 
I have a Cirrus Cs-20 BB Sub-Micro Servo that I have been using for testing. I was wondering how this servo compares to others like Futuba and others. Since I know how this one behaves, I can use that info as a comparrison. What Futuba mode is (...) (26 years ago, 18-Jun-98, to lugnet.robotics.handyboard)
 
  Re: System interupt problems?
 
you are correct, you are just attaching yourself to the beginning of the interrupt service routine, and the job of formatting system flags is taken care of by the ISR. however, i do see something that may be causing numerical errors. in the code, (...)

  Freewawre IC Error
 
I just got my hands on a beautiful old monster of an AT PC (Cost=$0). I figured, why not transfer IC over to that computer, and use it in my workshop instead of programming the 'board on our main computer and then bringing it down to the basement. (...)

Thanks, I already know of these. I think I might just try and build one myself. Finding all the h/w will be the hard part. (...) ---...--- Shoot-to-Win Protect the 2nd Amendment ---...--- (26 years ago, 18-Jun-98, to lugnet.robotics.handyboard)
 
  RE: System interupt problems?
 
(...) I'm pretty sure that since the Handy Board also uses TOC4 as its system interrupt, that it takes care of clearing the interrupt. My code just gets linked in and gets executed before the Handy Board code (though I don't know what the HB code (...) (26 years ago, 18-Jun-98, to lugnet.robotics.handyboard)
 
  RE: Walking robot - Related Topic
 
Mike, I have actually seen only 3 reasonable quality walkers on the market (the 6 legged kind) but I have to admit that I haven't searched that far recently. Lynxmotion ((URL) do one which looks to be pretty good quality however it is a bit (...) (26 years ago, 18-Jun-98, to lugnet.robotics.handyboard)
 
  RE: System interupt problems?
 
Tim, I just scanned your code, so I might have missed it, but don't you have to clear (or set) a flag in your interrupt routine to reenable the TOC4 interrupt? Mike ---...--- From: Timothy B.

  Re: Handy Board Header
 
I once ordered male ED7xxx series and they work ok. I do like them. I never tried the female ones. According to HB manual, the Digi-Key parts are: 929974-01-36-ND - female 36 pins. 929834-01-36-ND - male 36 pins. Regards, -Pandit ---...--- (...) (...)

  Re: Hot Wire Anemometers
 
(...) Actually, I'd want to modify the curve. Stock, the cars run very rich. For people interested in getting the most hp out of them, we'd want to be able to lean the engine out a bit (along with reducing the intake restriction). But this is (...)

  Re: Hot Wire Anemometers
 
(...) Not to mention that the sensor that is already built-in to the car is probably non-linear as well, which means that the software in the car's computer is already set up for that specific curve. If you were to replace it with another (...) (26 years ago, 17-Jun-98, to lugnet.robotics.handyboard)
 
  System interupt problems?
 
I need some help! We have a handy board hooked up to some decoders, which we will use to help track our robot as it moves across the floor. We have to do a few pokes and a peek to read the decoders, but we've got it all set up and it works (...) (26 years ago, 17-Jun-98, to lugnet.robotics.handyboard)

(...) Mass airflow sensor on a Eagle Talon/Mitsubish Eclipse/Plymouth Laser. Hmm..it sounds like it might be a lot more work to actually get something like this to work reliably in a car where all of the above can vary by a great amount. -Paul (26 years ago, 17-Jun-98, to lugnet.robotics.handyboard)
 
  RE: Cheap air flow sensor
 
(...) I'll have to check this out. We havn't actually used hot-wire-anemometers recently, partly because we havn't had the need, and partly because vortex-shedding flowmeters are all the rage right now. My memory is they are not linear, but that the (...) (26 years ago, 17-Jun-98, to lugnet.robotics.handyboard)
 
  resistor network
 
One more question. Are the resistor networks common bus or isolated? Thanks (26 years ago, 17-Jun-98, to lugnet.robotics.handyboard)
 
  Re: Handy Board Header
 
make sure you get FEMALE header for the HB itself. The only male header is for the LCD, to plug it into its female socket on the HB. It looks like the ED72xx parts are MALE. You probably want ED71xx for female. Please note I haven't ordered ED7xxx (...) (26 years ago, 17-Jun-98, to lugnet.robotics.handyboard)
