- a motion sensor board (MCCU=ATTiny45) networked to a bridge board with a blue LED as one of its components.
- In this iteration of programming, I edited Neil's Make files and C-code from these weeks:
- Embedded Programming
- Input Devices
- Output Devices
- As a person moves into the range of the motion sensor, the LED flashes once when someone enters the sensor's field, flashes twice when someone leaves the field. The MCCU sleeps when no motion is detected.
- So instead of characters being sent to the bus board (as in Neil's program example from E.Networking and Communications), the LED is triggered to flash. This communication was achieved by switching the ribbon cable wires (for transmit/receive) to reflect the communications between MCCUs.
- Further iterations are to yield a solar-powered, motion-sensor connected to RGB-LED strips.
- Their function is to bring lighting and a sense of safety, without surveillance, to public areas with limited to no lighting.
- Applications could include small parks, alley-ways, bus shelters, pedestrian bridges, etc.
- The full project proposal can be found at Principals, Practices and Project Management.
- Rapid Prototype of the Encapsulation for Circuitry and Wiring,
- designed in SolidWorks and printed with the Ultimaker 3D Printer, using PLA filament:
My final project, proof of concept, is composed of the following:
Here's the hand drawing of my proposed device's encapsulation from back in February:
The boards fit snugly inside, but I need to waterproof the housing and the circuit boards as well to ensure the viability and long-term functionally of the device, as Neil described during my final project presentation (the slide and video can also be seen in this clip):
I believe that Neil misunderstood the photos in my slide, so allow me to provide an explanation of what can be viewed in the clip: The circuit boards and ribbon cable are floating in space on the slide so their details can be SEEN for your viewing pleasure, ONLY. When the circuits and wiring are inside the housing, they can't be seen because they are enclosed INSIDE the housing. This is a rapid prototype with forthcoming iterations as the device is being marketed to the State of Michigan's Department of Energy as a public lighting solution. I will incorporate Neil's suggestion for also encapsulating the circuit boards themselves, for more robust functionality as the device will be OUTSIDE in the cruel Michigan winters. I want it to be built to last and Ford tough, etc. You don't have to be a Stanford d.school or MIT graduate to understand and apply the processes and strategies of rapid prototyping and design thinking.
The device will be installed at this location, pending city approval after the sidewalk and sitting area has been renovated:
