  IC installation problem
 
Dear Sir, Iam getting started with my project. At our lab we are having freeware version of IC (version 2.8). We tried to install the commercial version 3.2, but we are facing some problems. We tried to install from the site you told i.e (URL) you (...) (26 years ago, 19-Oct-98, to lugnet.robotics.handyboard)
 
  Re: platform choices...
 
If money is not an issue, Mondo Tronix' Robot Store has variuos robot bases. One is large enough to hold a laptop and a great many sensors. --phil (26 years ago, 19-Oct-98, to lugnet.robotics.handyboard)
 
  RE: platform choices...
 
From the pictures, it seems that this is a vehicle called 'Hercules' (or something close). I have seen it at the FAO Schwarz store recently. I have no details on how the truck operates, though the details on the box indicated that it can raise and (...) (26 years ago, 19-Oct-98, to lugnet.robotics.handyboard)
 
  Re: waterproof seals (a bit OT)
 
(...) A little off the wall, but would it simplify the sealing if you could pressurize the inside to something close to the pressure outside (equalize pressures). A miniature CO2 cartridge with a release valve may help. Mike (26 years ago, 19-Oct-98, to lugnet.robotics.handyboard)
 
  platform choices...
 
Hi: When I was in school, we built an autonomous mobile robot based on a six wheeled, 'electric ride-on toy' from Toys-R-Us. It had a sturdy metal frame, two nicely geared motors, a decent battery. It worked fairly well and could carry a large (...) (26 years ago, 19-Oct-98, to lugnet.robotics.handyboard)
 
  Re: Address locations port d and y0
 
it's in the faq, at (URL) you do is write to 0x4000, 0x5000, 0x6000 depending on whether your latch is attached to Y0, Y2, or Y4 (respectively). e.g., "poke(0x4000, 0xff);" will set all the bits of a latch attached to Y0 to 1.

  NEC V40
 
Sorry to intrude, I would like to check with people of this list if any one have used the NEC V40 ucontroller before. I'm doing a project on this and have problem programming the timer and intrl3. Kind reply to me personally at (...) (26 years ago, 18-Oct-98, to lugnet.robotics.handyboard)
 
  Address locations port d and y0
 
Ok I've had another read of the FAQ, as well as a close look at the schematics for the handyboard and the expansion board. Correct me if I'm wrong, but I think I can use d0-d7 along with Y0 or similar and hook these into a HC374 to get some digital (...) (26 years ago, 18-Oct-98, to lugnet.robotics.handyboard)

  File Types
 
Hello, I need help with the file types used by the handyboard. There are c, asm, icb, and lis files. How do I work with them? For example, I downloaded the compass.icb and compass.c files from the HandyBoard Site. Do I need to download both of them (...) (26 years ago, 17-Oct-98, to lugnet.robotics.handyboard)
 
  RE: waterproof seals (a bit OT)
 
Mathew, I dont know if they would handle 103 psi but the drive shafts used in RC boats are sealed where they go through the bottom of the boat. If you put your motor in a sealed enclosure with the shaft coming into the enclosure you may be able to (...) (26 years ago, 17-Oct-98, to lugnet.robotics.handyboard)

I'm having trouble assembling the serial board. When I do the test(see snip below) I only get about 5 volts. When I try and run the downloader, I don't see the green light come on.

  RE: waterproof seals (a bit OT)
 
You could do what they do for aquarium filter pumps -- use magnetic transfer. Put a bar type magnet on the motor shaft and put a similar magnet on a propeller just outside the hull where the motor is. Since propellers require low-torque it works (...)

  Re: waterproof seals (a bit OT)
 
(...) 200ft is about 7 ATM, roughly 103psi. Your're gonna need some really mean seals, and some serious current to turn motors within those seals. Lots more current than the 293's can handle. Probably easier to do what the big ROV's use. Take (...) (26 years ago, 16-Oct-98, to lugnet.robotics.handyboard)
 
  waterproof seals (a bit OT)
 
I'm interested in building an underwater ROV and am wondering if anyone has any insight on buiding waterproof seals for the motors.(I'd like to eventually be able to go down 200 ft or so). I realize this is a bit off topic but hope that someone may (...) (26 years ago, 16-Oct-98, to lugnet.robotics.handyboard)
 
  Digital Outputs
 
Hi all, I'm looking to try and get some digital outputs from the Handboard. I've read in the FAQ that this is possible using HC374(?), but I'm not sure how to do this or where to hook bits up to. Has anyone done this with some pictures or something (...) (26 years ago, 16-Oct-98, to lugnet.robotics.handyboard)
