IntroductionHi! This will be my tenth and final blog for the Design for a Cause challenge. It was a fun journey with a lot of things I've tried for the first time, from the fingerprint sensor to the RFID module. In the last 9 blogs I've covered everything regarding the build and general process of going through with this project. My initial plan with which I stuck till the end is to construct a device that will pick a key for us, depending on the door that we approached. I didn't manage to add a ...
IntroductionHi! This will be my ninth blog for this challenge. This is going to be the last blog where I will be making something, after this blog all that's left is to assemble everything into a single package and code it. The only thing left to make for the prototype is the key locking mechanism and adding a couple of reinforcements to make it all a bit more sturdy. I will also be adding the servo which will be choosing the correct key for us depending on the RFID tag that it reads.   I ...
IntroductionHi! This will be my eighth blog for this challenge. In the last update (Fingerprint Skeleton Key - Key Picking Mechanism Part 1 - Design for a Cause Challenge - Blog Post #7) I've started and finished most of the build for the key picking mechanism. I will be finishing up that part of the build in the next update, but now I will go and get to know the last module that I will be putting onto the device, the vibration detection module. Besides the module I will also test out the batter ...
IntroductionHi! This will be my seventh update for this challenge. In this update I will cover the key picking mechanism. In the sixth blog (Fingerprint Skeleton Key - Slider mechanism part 2 - Design for a Cause Challenge - Blog Post #6 ) I constructed the key holder and the spring holder mechanisms. The key picking mechanism will go on top of it and will chose the right key for us using RFID which I talked about in the third blog (Fingerprint Skeleton Key - RFID Module - Design for a Cause Cha ...
IntroductionHi! This will be my sixth update for this challenge. In this update I will tackle the main part of the build which I already touched on in the second update, and that being the slider mechanism for the keys. Just want to point out that for now I will be using plywood for several reasons, I don't have an access to a 3D printer at the moment, it's pretty sturdy for what it is and it's much easier to work with it than with metal, so for the purpose of keeping this project on tracks, I w ...
IntroductionHi! This will be my fifth update for this challenge, this will be a short update where we will take a look at some of the things that will provide feedback to the user of the skeleton key device. There are three different types of signals that I would like to incorporate into this build and that would be light, sound and tactile signals. Since this project is primarily aimed towards visually impaired people, sound and tactile feedback are of great importance, but having the light sig ...
Introduction Hi! In this update I will be taking a look at connecting a capactive fingerprint module to an Arduino MKR1000. I looked all over online, and could only find optical fingerprint sensors being connected to the Arduino, so I thought, why not give it a shot with a capacitive one, and if it works great! I want to integrate the fingerprint module to for now use it just a necessary switch, but will try using a solenoid in the device which would completely lock it. First, let's see what's a ...
IntroductionHi! This will be my third update for this challenge, in the last update I made first steps in trying to make the slider mechanism for the skeleton key. For this update I will be taking a look at the center of the project, the Arduino MKR1000, as well as RFID module, to be specific the RC522. As I've talked in my first blog (Fingerprint Skeleton Key - Concept - Design for a Cause Challenge - Blog Post #1 ), there were multiple ways and ideas for how my device would recognize a door, a ...
IntroductionHi! This will be my second update for the fingerprint skeleton key project. In this update I will explain what the slider mechanism is, about which I talked in my first blog (Fingerprint Skeleton Key - Concept - Design for a Cause Challenge - Blog Post #1 ) , as well as start making it. The first idea was 3D printing a lot of the parts for it, like the special key trays, but I will have to change my plans, since the makerspace is closing its doors for the summer until the 27th of Aug ...
IntroductionHi! This will be my first blog for the Design for a Cause challenge. I am extremely happy to be chosen as one of the challengers and would like to wish the best of luck to everyone participating in this challenge! This idea came to mind as a last minute idea to me. I was trying to think of the things people usually find annoying in their everyday life, and thinking how would a visually impaired person cope with a problem like that. In one point I thought of a normal key ring, somethi ...
