Do we loose points for melting the eggs? At any rate, it makes the foil stay on better. ;-) --Peter (19 years ago, 22-Mar-07, to lugnet.events.brickfest, lugnet.robotics, FTX)

Hello World, pbLua-Beta2 is out and 90% of my wishes are true now :D Running pbLua with OSX worked out of the box... 1. Flashing NXT and reboot the box once 2. checking for new NXT-Device (ls -la /dev/tty.usb*) 3. connecting with screen to NXT (...) (19 years ago, 21-Mar-07, to lugnet.robotics.nxt)

(...) I guess what I'm saying is '<<=', 'OP_ASL' and 'OP_LSL' are all the same thing (zero fill). '>>=' means either 'OP_ASR' (smear fill) or 'OP_LSR' (zero fill) depending on whether your target is signed or not. If you wanted direct equivalents (...)

(...) Will, If you do manage to combine RCX & NXT, I expect it will look mashed-up, but unlike all the other stuff at BF, this is not a how-does-it-look competition.

| | Adding syscalls/opcodes to NXT-G
|
|
One of the biggest problems with extending the current FW is that the NI compiler for NXT-G/NXTToolkit is not so flexible. In particular, one can't add new syscalls. Here's a suggestion I would be happy to hear your ideas on - the NXT-G compiler has (...) (19 years ago, 21-Mar-07, to lugnet.robotics.nxt)

I think one way to do this uses a differential (URL) and a pole reverser (URL). I don't have a picture to hand but the idea is simple. One side of the differential is connected to the low torque "input axle". The differential housing is connected to (...) (19 years ago, 21-Mar-07, to lugnet.technic, lugnet.robotics)
