NXT-G support for Power Function

Friday, September 14th, 2007

I’ve asked mindsensors.com regarding NXT-G support of PF motors via their NR-Link. Indeed, the NR-Link can remotely (via Infra-Red) control PF motors. Here’s their reply:

NXT-G block for NR-Link, has groups of macros for RCX/Train/PF motors. From the ‘Action’ pulldown, select the device you are going to talk to, and from the ‘Macro’ pulldown choose appropriate macros.

The NXT-G blocks are located here.

GPS and the NXT

Thursday, September 13th, 2007

I have allways considered communicating with a BT GPS using the standard firmware an impossible mission. Reason is that the standard firmware has it’s own standard for building messages over the BT serial port. Well, Antonio didn’t think so… and managed to overcome these. From his email, I understand that there’re still some small problems with this NXC code - but it does stream NMEA data (the default GPS textual format) to the NXT. With his permission, I uploaded the code for firmware 1.04 here. In a coming post I’ll try to explain in more detail the problems I thought will make this impossible.. and how Anotoni solved them!

Now I only need to find enough time to make a NXT-G block which follows the same strategy and simply returns world coordinates… Well, since I have no BT GPS it can be a bit difficult.

ANxT challenge extended to October 1st

Friday, September 7th, 2007

A new high-score in the 3rd NXTasy challenge! Lren has reached a bofy/weight ratio of 24 - passing 222Doc previous score of 21. I’m very pleased to get this new contribution, as the number of participants is still too small. I’ve decided to extend the ANxT challenge deadline till October 1st, so if anyone thinks he can still beat Lren - go to the drawing board!
