Following up “The Open Lidar Project – Hack the Neato XV-11 Lidar” post, we are happy to tell you that the unit is hacked by user Hash79. He and several others (including major contributions from user Xevel) managed to crack both the 2.1 and 2.4 firmware’s output data, including distance info, angular data and checksums. The unit takes 360 distance data at 1 deg increments at 10 hz. It can range up to 6 meters. You can follow the whole saga here: http://forums.trossenrobotics.com/showthread.php?t=4470 .

Big thanks to RobotNV and Trossen Robotics (who both donated $100). RobotShop also offered the refund the cost of the robot if it was bought from them, but Hash79 had bought his unit from Amazon.

There is still an outstanding $200 bounty from RoboDynamics for using the unit for doing SLAM navigation from point A to point B in a room.

This project shows how to build a 60W solar panel using common tools and inexpensive and easy to acquire materials. It will guide you through buying the solar cells, building the box, solder the solar celsl together,  install the panel on the box, install a blocking diode, testing the solar panel etc. Check details on the link below.

This project shows how to build a 63W solar panel using plain materials. It will guide you through everything from building the frame to soldering the solar cells. The frame is build of plywood and solar cells is better to be soldered using a low wattage soldering iron. Finally you add the plexiglass  and your panel is ready. Check construction details on the link below.

This project is a wireless temperature and humidity sensor with USB interface based on obdev’s RemoteSensor example and their firmware-only USB implementation. The main change is the replacement of the analog sensors with a Sensirion SHT11 digital temperature and humidity sensor. The sensor unit consists of an ATTiny45 microcontroller, a SHT11 sensor, and a hoperf RFM12 868 MHz transceiver module. Check details on the link below.

This project is a capacitive touch sensing keypad with 6 buttons based on the QProx QT160 charge transfer proximity sensor chip. When a button is pressed the circuit provides some visual feedback, a clicking noise and translate the output into an i2c bus signal. Special mylar capacitors are required for it to work properly. Check details on the link below.

Mike Shatohin build this LED Ambient lighting named AmbilightUSB. It uses a ATtiny44, 4 RGB leds, 74HC595 and USB connectivity. It is able to analyze the computer screen color information and reproduce the screen colors on the back of the screen. The software is cross-platform and can be run on Linux or Windows. Check schematic and details on the link below.
