We have developed various software applications to interface and program our Programmable Bricks. Please take note that these aren't that useful unless you have a Brick around to program! You won't be able to download without the password. Also note that you might need to download the latest version of Java (v1.3.1)--you can get it for Windows or Mac OS 9.x [ 5.2 MB ]. Special tip for OSX users: if you have problems downloading the OSX version of LogoBlocks, try holding down the CTRL key and then clicking on the link, and then selecting "Save Link Target As..."

LogoBlocks v3.5.1   ( 2002.12.20 )
 OSX

 PC

LogoBlocks is an iconic version of CricketLogo and YellowBrickLogo. It allows Cricket or RCX users to design programs by dragging blocks (each containing a bit of Logo code) from a palette and assembling them into a "stack," after which they may be downloaded to the Brick. LogoBlocks is part of our continuing project looking at Building Block Programming.

Check out the "readme" file included for more detailed information. If you use the OSX version, please note that you'll need to install the files in the "support" directory before use.


Jackal v1.7.3   ( 2002.07.31 )

Jackal replaces both CricketLogo and YellowBrickLogo. It runs on Java (v1.3.1), so you don't need Microworlds to use it. It includes features such as:

  • program a Cricket or an RCX in Logo
  • syntax colouring in the procedures window
  • internationalized for Spanish and Portuguese
  • built-in bus-device library downloading
  • the ability to remote-control a Cricket over the internet
  • customizable interface (skins!)
NOTE: On a Mac, if it doesn't open the first time, you might need to download swing - unstuff it, and put it into your "System Folder/Extensions/MRJ Libraries/MRJClasses/" folder


LogoGraph Mac

LogoGraph uploads numeric data from Crickets of RCX bricks and graphs it. Find out more at the LogoGraph homepage. Features Include:

  • Save and load data, export to Excel (teb-deliminated)
  • Zoom to any are of the graph
  • Support for Crickets and RCX
  • Title graph and label data
  • Print in color, save to PICT file

CricketLogo is the main application we use to program the Crickets in a varient of the LOGO language. Current versions run on either MicroWorlds or Java, for Mac and PC. CricketLogo contains all the constructs of a typical programming language (such as procedures, variables and control structures) but also allows for the control of the Crickets motors, sensors, and bus port. NOTE: you cannot use this unless you own a copy of LCSI Microworlds 2.3. However, this should work with the demo
