(...) I just uploaded a new nextscreen.zip with both versions of the NeXT Screen utility. The one which uses an image of the NXT now supports scaling via the right-click popup menu. You can scale from 1x to 4x with several fixed steps in between. I (...) (17 years ago, 11-Apr-07, to lugnet.robotics.nxt)

After one round with 25 Educational NXTs, I'm short 3 motors, a few sensors, some minifigs, etc. In the past few years, I've lost several RCXs. It's the nature of the beast. Half (...)

As usual, sets don't last a school term before some parts go missing. I can't find Technic Beam 13 (aka Liftarm 1 x 13 thick) in Md-stone color from either peeron or bricklink. Although, Briclink has some in pearl. So what are my other options to (...) (17 years ago, 11-Apr-07, to lugnet.robotics.nxt)

Michael Anderson had a great idea for an NXT tool for BricxCC. He envisioned a PC screen which would show whatever was on the NXT screen, only scaled to a larger size.

Hi Christian, (...) the RS-485 interface is directly connected to the AT91SAM7S USART, so you can choose the bit rate quite freely. (...) No, it is not necessary, P-Net is just a field bus which seems to be popular in Denmark, there are others which (...) (17 years ago, 10-Apr-07, to lugnet.robotics.nxt, lugnet.robotics.nxt.nxthacking)

Simple cheap MCU like ATMega didn't support this bitrate (as far as I know). To add an external devices (e.g MCU+SD-Card (...)
