I left the humidor project for a little due to work in Saudi Arabia, but now I am back, and I developed a new circuit that will include 18F4550 . The software is still in dev. state, but this are some of the new futures:

• it will support USB boot loader - so software can be changed via USB cable
• totally re-design of the software
• software RTC - no need for additional IC
• I2C extender for the LCD and RPG controll
• 3 PWM channels for light - so RGB leds can be introduced in to the humidor
• future USB connection of the humidor to the PC.
• up to 2 TECs, separate control, 2 inner fans
• fully configurable - so you can choose to have for example a direction relay for the each TEC or just cooling, to enable, disable each sensor, water pump, TECs
• new software to handle all the faults, including abnormal operations, hardware faults, alarms etc.

For now there is no estimated date for the release of the new circuit but work is in progress :):):). This is my free time project, when it's ready it will be ready :).
