Auto Fill Circuit for Laser Cooling Loop – Ethernet Data Logging

Here is an automation solution with a ethernet usage. The code and diagrams are also there. This is something that covers many aspects of engineering in one project. Try such things out to learn, only after you have mastered the basics.

“The Ethernet connection is based on an XPORT form Lantronics. Basically it lets you use a serial port to send things over Ethernet. A PIC microcontroller with an A/D converter digitizes the pressure, the pressure set point, the high and low pressure alarm points and the supply voltage (since everything is ratio-metric). “

DIY Radio Control Electronic Projects

This project, called “Simple-Timer” is a programmable Timer and electronic switch with an integrated LiPo Battery Monitor that is based around a PIC microcontroller.

Simple-Timer

The “Simple-Timer” includes a fairly accurate timer that is programmable (via pushbutton) by the user and can be programmed to time a 5, 10, 15, 20,25 or 30 minute event. When the timer/switch is enabled (tap small pushbutton), the onboard LED indicates the output is active by lighting solid (the circuit also outputs the same voltage as your supply/battery voltage using a PN2222 NPN transistor or a high current MOSFET).

CAn Remote Automation-Control with AVR

CARACA is a home automation project based on a net of interconnected programmable circuits suited to perform different tasks like switch on/off appliances, decode commands from Ir remote control units, control thermostats, measure temperature and more.

CAn Remote Automation-Control with AVR

Every node of the net communicate each other through a robust protocol (CANBus), and the status can be monitored by a PC possibly connected to the Internet.
