 | | Broken charger board...still broken

Hi all, just in case anyone feels like helping, I thought I'd post an update on the current (and very sick) state of the charger/interface board I accidently turbocharged by plugging the 120V adapter into a 240V outlet. As stated in a previous (...) (22 years ago, 27-Jan-02, to lugnet.robotics.handyboard)

I am working on a robotic blimp project. I've acquired the Garmin GPS25-LVS receiver and I want to use it with the HandyBoard to control the blimp. Does anybody have a schematic that would show how to connect this GPS system to the HandyBoard, and (...) (22 years ago, 24-Jan-02, to lugnet.robotics.handyboard)

Thanks to all who offered help. But I'm afraid I may need some more... In response to some questions: Yes the pop came from the board, not the wall-mounted adapter, and yes, I do have a voltmeter. But it hadn't occurred to me to check the testing (...) (22 years ago, 23-Jan-02, to lugnet.robotics.handyboard)

I thought originally you were interested in building .icb files, not rebuilding the pcode file. If you want to rebuild the pcode, you need the HB distribution of the pcode, which is at (URL) . There's also a makefile that has the flags for building (...) (22 years ago, 23-Jan-02, to lugnet.robotics.handyboard)

Hi all, yesterday I mistakenly plugged the 110V/9V AC adapter that feeds the Charger/serial interface into a 220V power supply (I live in NZ but used to live in the US and have a weird mix of appliances, converters, and transformers). After a few (...) (22 years ago, 22-Jan-02, to lugnet.robotics.handyboard)

Howdy Fred, Yes, I did download the zip file from the HB site. As11_ic.bat is present. One question I have is with regards to the various references to Rev 2.1, Rev 2.2, et cetera, in the README file. How do these references relate to my V1.21 HB (...)

I don't have any connector in the J11 space (middle right edge of the expansion board). All I have are 9 holes in the board that are in the same configuration as the bottom of the sonar module's 9-pin male connector. So if I solder the bottom of the (...)

There was a very undetcible component-side solder bridge between pins 2 and 3 of RP4. I might not know until tomorrow when I can get a replacement for RP4 (apparently I'm not very good at desoldering, and I didn't see the bridge at all until I (...)

Hi, Thanks for your reply. RP4 has the part # 88102G, and adjacent pairs of pins have resistance of 1k (ie, 4 discrete resistors). Ok, Tell me if this sounds really strange... R15 is installed, but tested at about 1k ohms, not 47k. I remove the (...) (22 years ago, 16-Jan-02, to lugnet.robotics.handyboard)

Sam, can you check the serial input circuit. if this is not correct, then the 6811 won't stay in boot mode. make sure RP4 is a 1Kx4 resistor pack (4 discrete resistors) and not a 1Kx7. also make sure R15 is installed. see (URL) . also, try putting (...)
