PIC NIC Ethernet Controller
PICNIC is a project to add 10BaseT Ethernet controller to PIC17F877, and it can run as an network-enable device.
This project is based on tristate's PICNIC product. And I just change the temperature sensor's circuits to improve the precision on A/D convert and add another Temp-Sensor channel.
Features:
* Build in Realtek RTL8019AS Ethernet Controller IC (10BaseT)
* MAC address are configurable via rewrite the 93C46 eeprom.
* Build in RS232 serial interface can connect to any host, and Transfer/Receive via network by UDP protocol
* LCD interface, can show IP address and any message by UDP protocol
* Drive the output port to I/O or H/L, could be used as an extension.
* Build in WWW server to show and change the configuration.

Build your own LC Meter and start making your own coils and inductors. This LC Meter allows to measure incredibly small inductances making it perfect tool for making all types of RF coils. LC Meter can measure inductances starting from 10nH - 1000nH, 1uH - 1000uH, 1mH - 100mH and capacitances from 0.1pF up to 900nF. The circuit includes an auto ranging and "Zero Out" function to make sure the readings are as accurate as possible ... [more] |
