This is a project that can prevent people from touching their phone during the work .
that’s how it gonna work :
- set time on the computer
- put the phone on the input device
- if someone remove the phone from the device, the output device will be trigger and shoot a “bullet” .
Out put: a nerf gun, a motor and a rubber band
in put: weight sensor, phone holder .
For my final project I am tossing us either further develop my door bell or starting with a new idea.
1 – The new idea – Physical controls for a digital world.
This idea adds physical elements reminiscent of the typewriter to the laptop. Intended for writing, the physical interface slows down the writing process and forces us to move.
This project would require an Arduino capable of inputting information into the computer, such as the Arduino Mini. I believe this is called a gpio breakout board. When pulled the level would trigger a switch and trigger the return key of the computer.
2 – The old idea – Ding Dong Knock Knock Door Bell
As there is limited time to refine the project before needing to produce a video and instructable I may be better off refining my door bell this would include.
- Connecting it the internet and use IFTTT to trigger an email when the door in knocked
- Miniaturising the circuit to fit within a case. This would allow me to create a instructable article around a more refined design.
My final project will be on the same trajectory as the stroking porcupine, my last project. Using a capacitive sensing system, I want to create a vertical garden that represents one’s emotional wall.
Everyday, in our interactions with others, we gauge/warm up to/distance/trust/close off/let in others. Similarly, pods of grass loosen/appear with a nice gentle stroke and hide behind the with hard slaps.
- Build a 12″x 12″ frame for a “wall” that stands upright
- Make a square insert of grass that would become the capacitive sensor
- Run conductive copper tapes in the back of the square and fill with dirt&grass
- Complete the circuit by connecting the copper tapes to Arduino shield
- Determine whether it’s a slap or a stroke by measuring the length of the touch with capacitive sensing grass
- Use a motor for pulling in the squares of grass when they’re slapped
Grass wall retracts:
Still need to define how to make the grass square slide back and forward (servo? belt?).
For my final project, I’d like to make a hidden Nerf/disc gun in an enclosure that looks like a speaker box. The speaker box would be able to shoot the disc and send audio, particularly to shout “Heads up”.
I have a few ideas of how/when to activate the gun and sound:
- Shoots, then says heads up
- Heads up, then shoot (normal case)
- Shouts heads up, but nothing shoots.
- Productivity tool – monitors computer usage
- Spend too much time on Facebook, get shot
- Ignore emails, get shot
- Messaging – incorporated into Slack/Messenger
- 2 people can shoot each other
- Serious version… Shoots every time there is a gun death in the US
- Uses an IFTT to a website counter for gun deaths
- Nearby activated
- Add in sensor to shoot when nearby
Depending on the activation method, the internal sensors will change. However, first step will be to create mechanics to shoot discs. I am planning to take apart a toy gun like below to utilize the mechanics and set it up into the enclosure and activate from arduino. Most likely a servo motor to activate a trigger/spring.
I will also need wave shield to generate audio inside the enclosure.
I am going to improve my guitar concept.
I will build an integrated ring with mic, battery, neo-pixels, and processor all built in. It will be super simple; just place it under the sound hole, and start playing.
I plan to use my 3D printing skills to make a nice simple structure for my components to sit in.
- Miniature Metro Mini Arduino
- Electret Mic Input
- NeoPixel Strip
- 9V Battery Clip
- Pretty Toggle Switch
Sound Reactive NeoPixel Pendant
Sound Activated NeoPixel Ring
Fascinated by IoT and other wireless technology, I started with getting an HC-06 Bluetooth module.
Attaching the Bluetooth with the Arduino came next. I started by researching, building and applying codes to the Arduino circuitry. After a number of iterations with trials & errors, I started getting some headway with the connection.
Why stop at using an app when you can command by using voice, ‘Lights on’ and ‘Lights Off’ was what I was aiming at. Delving further into every instructable ever I finally managed to get to a workable point.
After changing this circuit, making tweaks in the code and searching for more Instructables, I finally got it to react to my voice.
The video to show the same.(Even though google does not understand my voice.)
Now that I have a successfully connected Bluetooth module, I wanted to take it to the next level. One way could be attaching a relay transistor arrangement and connecting to a REAL device, say a light/fan/coffee machine. I wanted to take a different direction and tackle another issue.
I wanted to make a light go on, whenever I got a new e-mail on the school email, just cause I tend to miss those all the time and why not. This is where the actual fun started.
After much research and deliberation, one of the possible ways could be to use multiple platforms and ways to make this happen using the resources I already had at hand.
- IFTTT is a tool which works on the basic if this then that principle, essentially I enabled the tool to; Whenever there is a new mail on email@example.com then send a web URL(through the maker for DIY projects) to change 0-1 on my host(antriksh.96.lt).
- Hosting a webpage/ making a temporary domain is simple but delving into SQL databases/ writing the PHP script is something I have no experience at, a genius friend helped me with the same. This essentially meant that IFTTT could send a call to change variables on my domain every time it detected a new e-mail coming in. There is some stuff going on at the backend,some of which I understand and most I do not.
- There is no existing application on the google marketplace that supports such a custom framework. So I started getting into making one. Using the MIT App Inventor(Only for android, IOS does not support app making like this).
- After placing, replacing and then replacing code blocks I got to a prototype which I can use with the app. Getting into the basic of the emulator is easy, but you can make full blown complex apps on these. My thing was very basic(not for me, though).
- Now I will try and experiment with this App in use on an android phone.
For this assignment, i built an innovative switch, which is a level sensor. this sensor can sense imbalancement and give output under different circumstances.
That’s how it works: the liquid in plastic ball is salt water, so every time it touches copper tape from above it creats an working circuit and light up the LED.
For the application of this device, the tack driver can install it on the top of the trunk, so it will alert the truck drive when the cargo in the trunk is unevenly distributed which can cause severe consequence during sharp turns.
