 | | 6V question - is this OK?
|
|
Is this OK for getting 6V to motors connected to the L293s? I tapped off the center of the battery back and get about 6V. I then soldered a wire at that point on the battery pack and then soldered the other end to pin 8 (Vs) of each of the L293s (I (...) (29 years ago, 20-Feb-96, to lugnet.robotics.handyboard)

Thanks to all who helped me restore my HB back to life. After shorting the battery pack on the board during the last assembly step, it turned out to be only the A1 processor blown. Also, a BIG THANKS to Prabal Dutta at Digital Micro System. I (...) (29 years ago, 20-Feb-96, to lugnet.robotics.handyboard)

Here's an interrupt routine I wrote to emulate Sony remote controls using the IR driver circuitry on the handyboard. The usage instructions are in the file. Note that you will need some IR LEDs and a little bit of circuitry like the one advertised (...) (29 years ago, 20-Feb-96, to lugnet.robotics.handyboard)

Hi all, I'm trying to compile an interrupt routine into an .icb file. However, when I run the as11_ic.bat file on my MS-DOS 286 machine, the routine hangs on the first gcc command. No errors, just goes away forever. Has anyone else run into this? I (...) (29 years ago, 17-Feb-96, to lugnet.robotics.handyboard)

Hi, Fred: You were right, Fred- changing computers solved the problem. I switched from using my Pentium machine to my old 386-33, and it worked fine. Some kind of timing issue?
