The idea behind this project is to have a laundry basket that tracks the laundry as it goes in and out of the hamper, and whether or not the laundry basket is full. This operation would also lead to some added features as the tracking of laundry can provide data to the user about their own clothes and how often they are used and washed.
Speaking broadly, the lighting controller measures the surrounding lighting level in an ADC conversion, stores the measurement in memory, and sets the brightness of an externally connected lamp by pulse with modulating the lamp's power line […] as the surrounding brightness increases, the lamp's brightness decreases.
The company I work for designs and manufactures various types of sensors and meters. I wanted to do something that I could really relate to or directly apply to my work. I wanted to crate my own power monitoring system using the Dragon 12 board.
The need for a fully automated, timing based execution system, for nutrient delivery to plant life spurred the idea for this project. […] The automation needed to provide a way to fill a bed with nutrient rich water up to a predefined level and then soak for a given time period. After the soak interval the bed needs to be filled to the point where a bell siphon engages and drains the plant grow-bed.
The Digital Meat Monitoring Device is a prototype of a meat temperature reading product which determines when a beef steak cooked in an oven or barbecue reaches a certain level of doneness. […] The temperature of the steak is displayed on the 4 digit display while it is cooking. Once the selected doneness is reached the LED flashes the color of the selection.
The project involves the design of a flex-sensor glove used to translate movement of the hand into PC control functions which are input to a host via the com port. The glove could be used for gaming purposes, reducing strain on the wrist by enabling the user to simulate a press of a control key while holding the hand flat on a surface or upright.
I designed and constructed a temperature control system that can keep 20 gallons of water at a steady temperature. The system inputs are one temperature sensor and two water flow sensors. Its outputs are two pumps, a heating unit, and a chiller unit. […] In the future I will use this system to regulate the temperature of a salt water aquarium.
The Sentinel required the building of a platform which rotated and held a weapon in place, learning new programming languages, and learning to use open source webcam applications. In the end it receives video input and is able to remotely stand watch over an area using outputs driven by the Dragon-12 board.
This project is to design a digital thermometer that can display the current temperature at any time. The temperature is displayed by LCD at the press of a button. [...] The temperature sensor can detect any change of temperature in the range -55°C to 150°C.
