|RayDialer||A local positioning system for robots, based on IR light beacons and empty beer bottles.|
|NerdpleXT||The mother of all NXT I2C sensor port multiplexers (show-off ;-). Supports 4 channel I2C, analogue pin and 9V-supply multiplexing. Available in three versions. Just a quickie...|
|pbLab Messofen||The successor to Messoefchen, an 18bit resolution measurement interface for pbLua and your NXT. Galvanically isolated for combined high- or low-side measurements. pbLua featured!|
A quick and dirty work for measuring the efficiency of non-isolated switching regulators. Saves a lot of
|Sharpliner||An external, bus capable 12F683 based, plug-in linearization and filter for Sharp distance sensors.|
|Legisplay||Need a bigger display? Here's a VGA or FBAS (video) interface for your NXT.|
(SPI 4 NXT)
|Need SPI on NXT? Need memory? Upgrade your NXT by interfacing a serial SPI RAM chip via only 2 wires. pbLua featured!|
|Sharp distance sensors||How to make your NXT measure liter per square meter. Which - in fact - is a length unit. Some assorted tips, hints, circuits, calibration and linearization.|
A Lego NXT based programming tool for LPC900 ICP.
|Servo||A little, cheap PIC controlled 6 channel I2C servo controller.|
|Laser Scanner||Distance laser line scanner with (some) daylight rejection. Distance is determined by analyzing 90° rotated (realtime) FBAS camera lines of a pulsed laser stripe.|
|Sharp Turret||A (nearly) realtime 360° optical radar-type environment scanner.|
|NeXTzwerg||An ethernet interface for your NXT. Can easily be upgraded to WLAN by attaching standalone WLAN bridges or router. pbLua- and Propellerized, what else ;-)|
Seeing is believing but listening is understanding.
A more advanced sound source following/localizing robot.
Upgrade of ChiChaBot, the children chasing robot ;)
|pbLua corner||There are lots of programming environments/languages available for Lego's NXT. Imho, pbLua beats them all...|
|pbCard||Need even more memory? Use SD-cards as (data acquisition) memory expansion. pbLua featured!|
|pbSerRAM||Need unlimited amount of transportable memory? Use anything that provides a serial interface (RS485/422/232).|
|ServoBus||2 wire powered servo bus. This brings the "drivers" to where they belong: The servos themselves. Minimizes cabling complexity.|
|Wii sensor||Attach a Wii-IR sensor to your NXT and see the infrared light of day.|
