Xander has released the V2.0b2 version of the ROBOTC Driver Suite.

• I changed the min, max and clip functions to macros and renamed them to min2, min3, max2, max3 and clip.  min2 and min3 are for two and three numbers respectively and will work with any type.
• I’ve added support for the MicroInfiniy CruizCore XG1300L with two example programs.  One is a text only example but I got a bit fancy with the second version and made some graphical representation of the data from the sensor.  Try it, you’ll like it, I’m sure.  The new driver is called MICC-driver.h, the examples are MICC-test1.c and MICC-test2.c
• Fixed MSDISTsendCmd() in the Mindsensors DIST-nx driver
• I added MSMMUX-test2.c to show how to use MMUX with a daisy chained sensor (DIST-nx)

Notice courtesy of Xander:

The electrical specs of these things are pretty impressive: they can handle a load of max 10A at 18V, while only pulling 1mA from your NXT’s batteries. If you look at the picture on the left you’ll see the small cooling fin; I would suggest you keep that somewhere on the outside of your robot if you’re going to run that much power through it, though. This device is about 5×4 units big.

Their price will be $24.95 each and are due to be on the shelves around mid-June.

Using this Relay Driver, you can control up to 2 Relays using NXT.
Instead of Relays, you can control high current motors also.
While controlling motors, you can control speed as well.

What is the GardenBot?

GardenBot is a garden monitoring system. This means that you put sensors in your garden, and GardenBot will show you charts of the conditions in your garden — so you can see the world the way your plants see it.

With all the steps you need to build one of your own… the GardenBot is a great summer project. And, it’s easily expandable too. Add wireless, expand your garden size, make it solar powered… tweet your garden stats. The options are endless…
