Geoff Messier's Projects & Ideas
The dAuratus board is named after dendrobates auratus (aka the green and black poison dart frog) which is currently acknowledged to be the smartest of all frogs. This is my AVR MCU board that serves as the platform for most of my home hobby projects.
A VDD of 3.3V is provided by an ADP7104 regulator able to accept a VIN of up to 20V. Includes a switch for turning VDD on/off which doubles as the hardware reset mechanism for the MCU.
Pins for interfacing to external devices:
|PA0-PA7||8||The USART and SPI default pins.|
|PC0-PC3||4||Timer, CCL default pins. USART/SPI secondary pins.|
|PD0-PD7||8||Comparator, ADC, DAC default pins.|
|1||PA7 (SS)||PC0 (MOSI)||GND|
|2||PA6 (SS)||PC1 (MISO)||PD1|
Named after the Northern Leopard frog, lithobates pipiens; a frog that can help keep gardens healthy by eating pests and is currently threatened in Alberta.
Implemented using a dAuratus board with the following functionality:
The central bbb interface to the home network. Named after Bufo marinus, the largest known toad.
A wireless protocol built on top of LoRa.
A simple filesystem for the external FLASH chips used on the dAuratus board. A play on will-o-the-wisps or ignis fatuus which were flashes in swamps scientifically attributed to the spontaneous combustion of marsh gas.
A controller for 12VDC fans to adjust their speed and gust pattern. Used to create air movement in a grow box to strengthen the plants and prevent fungus and/or rot.
