001 : J.A.R.V.I.S
Personal home assisant designed for modualarity and costomization with mesh networking to have every chip in your house work around you. This one controls 6 appliences and 3 sensors. Using a server as a middle man the different boards that serve different purposes can communicate with each other to create one cluster network of your home that is made for the express purpose of budgeting electricity usage, money, comfort, and time.
| OBJECTIVE |
The objective for me personally was to learn a little bit more about cross controller communication and more about PCB fabrication. As a product it's objective was to help reduce energy usage and waste as well as create something that would help turn any home into a smart home.
| TECHNICAL DETAILS |
The first thing I did was create a list of requirements for function which I followed with a bunch of components that can be used to initiate the action required for that function with a BOM (bill of materials). For example the requirement of having light control to switch on and off from anywhere was met with relays. I created a prototype using my breadboard and after it worked I created it on the PCB using EASYEDA.
| PCB DESIGN |
JARVIS, inspired by Tony Stark, is a all in one home automation system that uses 5V relays to control 6 appliances of your choice as represented by light bulbs using an ESP-32 controlled by Amazon Echo Dot’s Alexa as well as your phone using bluetooth, wi-fi, or manual switches. So if there is no wi-fi you can use bluetooth, if there is no bluetooth you can use the manual light switches, the status of the connection is indicated by the three red lights on the PCB. This can be voice controlled with alexa, or you can use your phone which will also display the temperature and humidity using the DHT sensor, can alert you if there is a fire using the flame sensor, and can alert you if there is a gas leak using the gas sensor. I designed a case to be made using a combination of a 3d print, screws, command strips, wood, and acrylic glass. The design is made to make the control panel fit in a home in terms of aesthetic and feel. The combination of minimalism and naturalism to provide a modern and natural feel to it. The command strips are for mounting without damaging the wall, screws to secure the 3d printed case to itself and mount the pcb with spacers, the wood is simply a small block that creates a horizontal divide to prode a geometric and architectural inspired shape, and the acrylic is for the light from the LEDs to shine through and diffuse.
| CASE DESIGN |
| OUTCOME AND FUTURE CHANGES |
I do plan on making a new and improved version with small and simple changes like having the microcontoller control either two or three apliences like a two gang or a three gang switch and be placed right on top of it and inside the wall wiring fixings to make it unnoticeable and invisable. Additionally there will be holes for the PCB pillars and screws to be mounted. Each switch pair would have its dedicated controller and the sensors in its own box. This is because I had alot of trouble creating trunking to wire the bathroom and hallway lights to the main board in the room which creates an unappealing and unnecessary addition as the controllers can communicate with each other wirelessly through mesh networking.
