Drool! New Technic Set Pics!

Friday, January 5th, 2007

Not exactly NXT-related, but given that Technic and Mindstorms are like milk and Oreo’s!

I just came across this posting and saw pictures of what looks to be upcoming Technic sets.. The Bulldozer looks pretty slick, comes with a IR remote and by the pictures, appears to have some very interesting small motors… Anyone have hi-res scans? Pass them on!

Winners of Challenge No. 1 - “Throw Me!”

Friday, January 5th, 2007

I’m very sorry for the long delay (real life issues), but finally I found the time to make the list of winners in our first NXTasy challenge. The image above is of “Spinner”, the award winning robot by Combat_Israel. This robot throws the ball 11 meter away. Combat_israel wins a digital compass sensor courtesy of HiTechnic.

The best 5 throwers are - Combat_Israel (430 inches), James German (204 inches), Rp181 (153 inches), msim (122 inches) and Todd Edmands (96 inches). All five will get a 25% discount coupon for online purchase in mindsensors.com.

The details (contributions, prizes, winners etc.) are found in a new page, which you can reach from the “Challenges” link on the top of NXTasy homepage, or directly using this link.

Lego S@H sale - NXT set, parts and other goodies!

Friday, January 5th, 2007

 Edit: Sorry folks, it appears that this deal is no longer available :-(   I received notice of it and I can confirm it was live because I personally ordered the colour sensor, some cables and other parts which were all processed at the discounted price… Guess it was a (very) short term deal (or mistake). 

Quick!  These deals may not last long, but the NXT set (and some other items) are in sale at Lego Shop at Home (at least for Canada!). If you are looking to buy a NXT or add to your collection, this may be your chance! Here are some items:

(Note - all prices are quoted in Canadian dollars)

  • NXT set $249 (from $349)
  • converter cables and connector cables down to $9.99 (from $14.99)
  • Rechargable battery $49.99 (from $69.99)
  • Compass sensor $46.99 (from $59.99)
  • Colour sensor $46.99 (from $59.99)
  • Note -the Compass sensor is listed on hitechnic.com for $46.99 (and the colour sensor may be the same once the price is listed) - so these two may not be such a hot deal.

There is a total of 93 items including those listed above.  Looks like I might just go after that colour sensor now!  Not sure how long the sale will be on…  http://shop.lego.com/SalesAndDeals/Default.aspx?va=1 

Not eXactly C

Tuesday, January 2nd, 2007

Please visit the Not eXactly C website (http://bricxcc.sourceforge.net/nxc/) for an important beta release (b19) which fixes a serious problem that can cause NXC files to be overwritten by generated NBC code when you download an NXC program within the BricxCC integrated development environment (IDE).

In beta 17 and 18 I had added a -N command line parameter to NBC which allowed the NBC compiler to save the intermediate NBC source code to the specified filename.  Unfortunately, BricxCC was using an undocumented -N parameter for a completely different purpose already (during the download operation) and I mistakenly thought that -N was available for use as described above.  The new beta release renames this relatively new option as -nbc=.

It is possible to work around the bug in beta 17 and 18 by always saving the active editor window in BricxCC after executing the download operation.

The latest test release of BricxCC (see the download link in the NXT News section of the BricxCC page) should be used along with the latest NBC/NXC beta release.

Most of the new features and bug fixes in beta 18 and 19 are a direct result of user feedback via email.  Please feel free to send me any questions you may have or reports of any problems you may encounter. :-)
