===== Project Synopsis =====
This list is an attempt to define each of the various projects underway in Tom's world.

* **DEGAS** - this is a web server and one wire temperature network consisting of an Atmega128 on an old hub card, an Avcom EasyLAN web server and a power regulator mounted on an old 8515 processor card. The entire hardware package is inside an aluminum chassis case. As an emergency temperature monitor, this was resurrected in June 2008 for use at Stoneybrook to monitor the HVAC system.

* **MEISTERSINGER** - this will be a Downing Place master controller with 2 uarts from a QYX card which is Atmega128 based. One UART hooks to the 485 network, the second UART attaches to the PC.

* **DaVinci** - This is an Atmega128 with an enc28j60 hooked to it. The compiler is WinAVR. This was initially started in Stoneybrook in Oct 2007 after learning WinAVR in an Atmel AVR class in Tampa.

* **Tracy** is a hub card wired to an enc28j60. Goal was to develop an AVR based web server. The compiler used was the AVR.

* **Hopper** is designated to replace the Bluebird Fred monitoring system. It has an onboard DAA, a text to speech engine, an Atmega processor and a one wire LAN.

* **Kahlo** is the microwave controller. Atmega164 with DC-DC, One Wire, analog interface out RJ45 pins. The analog consists of an op amp and  transistor for common relay driving, an OptoIsolator IL5 for driving the magnetron relay, an optoIsolator IL5 to detect door open, a buzzer, keyboard and LCD.

* **Rembrandt** is an embedded Linux Stamp based on the AVR32.

* **Loge** is an Atmega164 based card with 3 onboard 5 volt relays. A set of NO contacts from each relay is brought out to a terminal strip. Loge also contains an RS485 network for intra device communications.
Derivatives of Loge are:
  - Furnace selector
  - Fish pond water management
  - Crawl space ventilation timer with temperature and humidity sensing

* **Venus** is an Atmega128 based card for interfacing an RS485 network with an RS232, typically attached to a packet controller and radio combo. Venus will act as an RS485 bus master, polling slaves for status. Although Venus is a standalone controller, the ultimate will be to supply a web server with status information as a GUI interface to the network.
