SSAU0001 AT89C4051, AT90S2313 SimmStick MathCo Plug A AT90S2343 8pin AVR, pre-programmed w/IEEEFP into the I2C EEPROM SimmStick space, and you have powerfull, miniature controler.  I have the AVR Fp. The AT90S2343 works well for this and uses the x051/AVR host crystal for its' clk. Anon
SSUS0001 Electronic Elapsed Time Monitor This simple system provides a demonstration of a bare-bones DT-104 and the discrete I/O and EEPROM features of the 90S1200. It might have practical use as a "maintenance needed" indicator for construction equipment or similar items not otherwise equipped to log operating time. The single input is used to reset the elapsed time. Two pins are set as outputs and drive LEDs.
During normal operation the green LED flashes to provide an "ON" indication. The internal EEPROM tracks total operation time and is updated every 6 minutes. The yellow LED is off when elapsed time is less than 50 hours, flashing for times from 50 up to but not including 60 hours, and continuously on for times of 60 hours or more.

SSAU0002 An high-end SimmStick processor module Currently SimmStick processor modules exist for PIC and ATMEL processors. Why not using the same principle and pinout but with a high-speed SCENIX processor : 50Mips today, 100Mips very soon... That is my project : a new SimmStick-compatible PCB for SCENIX 28 pin processors, with an on-board high-speed ADC converter and extra memory. With it, DSP-class applications will be
possible with a SimmStick architecture! Project documentation

SSAU0003 PC controlled garden watering system A seven channel garden watering system based on a DT104 simmstick with an 89C2051.  Watering times are set up on a PC and down loaded via a serial port and stored in NVRAM.  Watering programs can be loaded and saved to disk.   Outputs are 24V AC for watering system solenoids.
Comment: PC software requires Microsoft Q-basic to run.  Watering computer software written with Bascom-Lt V1.20

SSAU0004 A simple sequencer This circuit emulates a device known as a drum sequencer, which consisted of a slowly rotating drum with cams which operate switches. It was conceived to control traffic lights in a school project, a miniature city, and as an excuse for playing with a PIC. The core of the application is a table containing the states of the outputs and the time spent in each state.

SSUS0005 Wireless Digital Thermometer A simple design which reports the temperature via any standard FM broadcast band radio at regular intervals. Commercial wireless thermometers are usually sold with only one receiver/display unit, and thus are limited to monitoring at only one location. My design allows any inexpensive FM radio to be used to monitor the temperature. Any number of monitoring locations can easily be set up. The unit transmits the temperature reading in the form of a tone sequence which can easily be interpreted by a human. Or,  by plugging the output of the FM radio into the sound card on a PC and running a program which I am developing, temperature data can be logged for later display/analysis.

SSAU0005 A remote control unit for the disabled This device was originally intended for the spinal injuries unit in a hospital, but would be useful for anyone who has difficulties operating buttons on a remote control or other device. The modular nature of simmstick is ideal for implementing this kind of design, as it allows the unit to be easily and cheaply customized for individual patients, while retaining convenience of PCB construction.
The unit can be controlled by any kind of switch that can be operated by the user (eg. breath switch, squeeze bulb). A series of LEDs are lit in sequence, each of which represents a particular function (eg. Nurse Call, Turn on TV). Once the desired function is reached, the switch is operated to carry out that function. 
In its current form, the unit consists of two DT101 simmsticks on a DT004 motherboard. One simmstick implements the LED scanning control, and the other accepts signals from the control simmstick and outputs infrared codes to control a selection of television sets. The LED display and other interface circuitry is implemented on veroboard which is plugged into the 30 pin socket on the motherboard.
Because of the modular design, it is possible to reuse the core control simmstick for different needs. For example, the infrared code generator could be substituted with a relay or opto-coupler interface, or the LED display could be replaced by a simmstick which generates audio cues for the visually impaired.
