 | | Re: Firmware file version?
|
| (...) The first line of each file should be unique, and you should be able to use it to infer the version number. At least the first line is unique for firm0309.lgo and firm0325.lgo. You can actually decode the lines if you like -- they are header (...) (24 years ago, 26-Nov-00, to lugnet.robotics)

| | RCX firmware equivalent ?

I like the MIT brick concept, but would like to be able to use a open system approach to hardware and software. It appears (...) (24 years ago, 5-Mar-01, to lugnet.robotics.rcx)

| | Re: Custom Firmware, IR Problems, and Dead RCXs (long)
|
| I'm hard pressed to understand why one would need to continually transmit from either the RCX or the tower? Data logging comes to mind, but there aren't many cases where there is a need for this. Listening can, of course, be done continously. The (...) (23 years ago, 29-May-01, to lugnet.robotics)

| (...) For what it's worth, it's not actually that bad. I don't know the specs on the NPN transistor, but I suspect 1.14A would kill it almost instantaneously. One important factor you've left out of this equation is the 9V battery itself. We often (...) (23 years ago, 29-May-01, to lugnet.robotics)

This does mean that you could change the duty cycle, but you should be aware that it would be at the expense of noise immunity and would require a higher sampling rate from the (...)
