What I did: I answered the questions below to better understand my final project.

 

 

 What will it do?

The device that allows you know if a parking space is available or not. Usually a person can see a red or green light that tells the driver if there's a free space, in this case either there is a light or there isn't.

 

 

Who's done what beforehand?

There are similar parking space detection systems like:

A) The invention relates to a free parking space detection method comprising: a step of sending, from a user to a server, a free parking space request specifying a location; a step of image capture apparatus situated in the vicinity of the specified location capturing one or more images of a parking area comprising a plurality of parking spaces and being associated with the apparatus (US20060220911A1)

 

B) An underground parking lot lighting control system using IP-USN is provided to predict the progressive direction of the vehicles and minimize energy consumption (KR100935736B1)

 

 

C) A method is disclosed for managing a parking lot. In one disclosed embodiment, the method includes receiving parking lot data. The embodiment of the disclosed method also includes transforming the parking lot data into parking lot information, the parking lot information including information about a moving parking lot object. Further, the embodiment of the disclosed method includes transmitting a map of the parking lot to a mobile interaction device, and transmitting the parking lot information to the mobile interaction device (US6816085B1)

 

D) A method for directing a vehicle to a parking space within an environment is disclosed. The method includes selecting a parking space from a collection of parking spaces within the environment, further selecting one or more lighting devices within the environment based at least on a location of the selected parking space, and sending a signal to the one or more lighting devices to generate a lighting pattern visible to a driver of the vehicle, where the lighting pattern directs the driver to navigate the vehicle toward the parking space. In addition, the vehicle may be navigated using radio navigation algorithms based on beacon signals broadcasted from streetside devices, such as lighting devices or parking meters (US20140320318A1)

 

 

 

What will you design?

I will design a parking lot model in Autocad so I can cut in with the laser cutter. I will also design the circuit boards and program. I will design and laser cut a small model of a parking lot to test the device. I will use the CNC router to cut the reflectors needed for the project (I will also design them). I will design the circuits needed for the device, I will also weld its components. I will code the program needed to control the device.

 

What materials and components will be used?

The material needed for the model is MDF. I also need a L928 Modul Driver, Open MV M7 camera, Raspberry Pi 3 Model B+, a WIFI NodeMCU ESP8266 (to test), two Motor Stepper NEMA 17, A receptor and transmissior Modul RF 433 MHZ, two phenolic plaques, two rechargeable lead acid 6 batteries, two 5x5 cm mirrors, pins, button,  two 10k resistors, three 220 resistors, 3 Leds,  one VREG 5V, one VREG 3.3V,  Atmega328, 16MHz,  six capacitors, two 22pf, jumpers.

 

Where will  they come from?

Sparkfun: Open MV M7 camera (65$)

Mauser: Raspberry Pi 3 Model B+ ($40)

Japo Electrónica: two phenolic plaques, receptor and transmissior Modul RF 433 MHZ ($30)

 Steren: two Motor Stepper NEMA 17, L928 Modul Driver, wo rechargeable lead acid 6 batteries, a lase light pointer ($65)

Fab Lab Puebla: ins, button,  two 10k resistors, three 220 resistors, 3 Leds,  one VREG 5V, one VREG 3.3V,  Atmega328, 16MHz,  six capacitors, two 22pf, jumpers, MDF.

 

 

How much will they cost?

Less than $200 dollars

 

What parts and systems will be made?

The circuits, the model,  the programs.

 

 

What processes will be used?

Computer aided design, laser cut,  electronics production,  electronics design,  networking communications.

 

 

What questions need to be answered?

How to program the light?

 

How will it be evaluated?

If the device recognizes where the is an available parking space.
