Gruezi/ Hi, (...) Instead of using the serial port, how about using the HP4**x IR port? I recall there being HP4**x programs that emulate IR remote controls which should be easy to modify (?) for general-purpose communications. Marco A. Assfalk de (...)

Hi all, I'm having some problems with me previously functioning handyboard. I'm using a standard board which has worked fine for nearly a year. Recently it didn't get any use for awhile and the batteries ran down. After charging them for 18+ hours I (...) (24 years ago, 5-Jul-00, to lugnet.robotics.handyboard)

(...) Not knowing what parts the HB uses, but assuming it is something like a polystyrene cap, then I think I have some in my component drawer. Send me your address, and I'll stick a couple in the post. Best Wishes (24 years ago, 5-Jul-00, to lugnet.robotics.handyboard)

| | Re: VECTOR 2X
|

This is my routine to use the Vector 2x with my board (see link below my name) with an I/O expansion board connected. You will need to change the I/O port #defines to work with the Handy Board I/O ports on your expansion board, but other than that (...) (24 years ago, 4-Jul-00, to lugnet.robotics.handyboard)

Hi Robert, It has been over a year since I have had the vector 2x connected to my board but if you follow the instructions that Tom Brusehaver posted in contributed software everything should work ok. You will have to connect to one of the motor (...) (24 years ago, 4-Jul-00, to lugnet.robotics.handyboard)

Hi all, I am currently fabricating my new HBoard based robot and have only gotten to the design stages. I have ordered a Vector 2x but haven't recieved it yet. I am not particularly well endowed with electronics or assembly language skills (very (...) (24 years ago, 3-Jul-00, to lugnet.robotics.handyboard)

| | HB Batteries
|
|
I am going to use individual AA cell batteries to power the HB mounted into two 4 cell holders. My question is this, if I use NiMh cells (1300mAh) rather than NiCd cells (800 - 900 mAh) how would this effect the HB ?. My current understanding is (...)

I have found that Maplins have only stopped stocking the 5% tolerance caps, they still do 10% versions. How critical is the capacitors value ?. I could probably try testing a batch of them in the shop using a multimeter but I couldn't guarentee how (...) (24 years ago, 3-Jul-00, to lugnet.robotics.handyboard)

I have got all the parts for building my HB except for a 6.8 nF 2% capacitor (component C6). Maplin Electronics have stop doing it and I am not sure where to try next. I am in the UK, does any body know if I can change the resistors in the infrared (...) (24 years ago, 3-Jul-00, to lugnet.robotics.handyboard)

I have three GP2D12s running on a Handyboard and they seem to run quite well in sunlight. In overcast or indirect light (shade) their performance seems identical to indoor light. In bright sunlight there seems to be a possible shortening of the (...) (24 years ago, 1-Jul-00, to lugnet.robotics.handyboard)
