a regulated supply would be really nasty when you put the interface board in ZAP mode -- the supply would try to raise the level of the battery to 15v or whatever, and that would be bad. so unless you really know what you are doing, steer clear of (...)

(...) Isn't this a bit sweeping? Surely the problem is that a 12v regulated supply will not have enough headroom with a 9.6V battery. I use a 7.2V battery without problems (that I am aware of).It is not the regulation that is the actual problem but (...) (27 years ago, 5-Sep-97, to lugnet.robotics.handyboard)

I was just curious with all the talk about serial routines if anyone has sucessfully attempted a wireless data link to the handyboard to the PC. It seems like if you had a fast enough wireless modem with a clean enough connection you should be able (...) (27 years ago, 5-Sep-97, to lugnet.robotics.handyboard)

(...) They're working great for me, no such problems. I can send/receive and decode characters into numbers very easily.

[Jodi Seaborn] spake unto the ether: (...) Hi Jodi, the serial input routines (i.e., from some other source to the Handy Board) do work, it's just that the I/O is polled, not interrupt-driven.

Good question. Answer: DO NOT USE REGULATED ADAPTERS WITH THE HANDY BOARD. I will add this to the FAQ, because it is not obvious, but the HB power circuitry was designed explicitly for CHEAPO UNREGULATED WALL WARTS ONLY. sorry, Fred In your message (...)

Hi all, Just another (hopefully unanswered) question about the DC adapter: Do the specifications stated in the FAQ (18 volts unconnected) also apply to _regulated_ adapters, or only to unregulated? I'm asking this because I just bought a new (...) (27 years ago, 4-Sep-97, to lugnet.robotics.handyboard)
