Visolate is a nice tool used to produce the cut paths of a PCB and minimize the cutting work needed by CNC router. This is done by calculating Voronoi diagrams. On the link below find out how to use this tool and make a board using a CNC machine.

Following the past posts about OpenPicus project:
An new release is of module happened.
Web of things, opensource and WI-FI
OpenPicus community release the first Wi-Fi module called FlyPort. It’s small and integrates the Microchip PIC24F (256K Flash, 16K Ram) and the new Microchip Wi-Fi certified module.
FlyPort runs the Wireless Stack (TCP/IP version 5.25 from Microchip) and the Application layer. It’s provided with a confortable 26 ways Male Pinheader connector to let you prototype and test easily. Zero investment is needed to start, no programmers since there’s the Brutus serial bootloader preloaded on the module. Applications and libraries are opensource, so you can freely download from openpicus website.
Programmers have full control of the Wi-Fi module, Low power modes are available. Flyport act as powerful webserver (you can run even Ajax apps based also on graphic libraries) or it may send you email or send data to a remote server.
Claudio Carnevali, founder of the OpenPicus project, says: “We believe FlyPort is a revolutionary device and we’ll be able to achieve a price under 30 Euro soon. Wi-Fi is the natural wireless platform for the Internet of Things, because it doesn’t need any gateway and expecially when your application can control the RF transceiver to save energy.”

ikalogic.com just finished IKA-TACH project which is a contactless Tachometer based on ATMEGA48 AVR micro controller. Detection of rotation is done using a IR transmitter / receiver module. There is also a red led that helps point the invisible IR led. This tachometer is able to measure both low RPM speed and high RPM speed. Check construction details and KIT on the link below.
