Color'er - update 1

Posted by delabassee Apr 30, 2016
While waiting for the kit to arrive, I've started to think about the mechanical aspects of the challenge.   Simple acts are sometime difficult to model as they're so simple that we don't really think how we perform them. The action of taking a cap off involve 3 forces (A, B & C), A & B are used to hold the 2 parts (sharpie & cap) and need to be performed at the same time while the third force (C) will take them apart and should be performed after A & B (while A & B are ...

So I have changed my mind a few times, but I think I have settled on something both achievable and more useful that the original.   Here are some of the ideas I have toyed with and some of their pro's and cons Header 1 Header 2 Header 3 The first design that sprang to mind is a  sort of ferris wheel system Pros. Cons. Simple Idea easy to implement easy to build a frame to let it stand space between baskets is necessary to access items inside The next option is a worm screw typ ...
1 The MPU6050 module is one of the main components in this design In my design a rotary frame is attached fore-arm and hind-arm  FRDM-KV31F is fixed to one part of the frame and MPU6050 shall be fixed in another one This is to provide status of the arm movement by comparing the discrepancy of two movement sensors Since I can not order same sensor as the one used in  FRDM-KV31F and this MPU6050 is in my stock For the purpose of testing the compatibility of my programming different typ ...
The Clear Walk project is progressing a bit slowly due to lack of parts and trying to find low cost solutions, but definitely seeing some effort expended. This past week I have been struggling to devise a 2-axis rotation mechanism for my mirror. Most options that might be strong enough and large enough seem to be very expensive. However, I think I finally came up with a solution that may be feasible on a budget. I can scrounge an old bicycle and use the front fork and steering race assembly. ...

Sensor Fusion Library 5.0 supports  the Freescale FXOS8700CQ low-power, six-axis Xtrinsic sensor, which is interfaced through an I2C bus and two GPIO signals. This is one of the key features for the implementation of this design, which requires the movement gesture capture and pattern matching. This library fusions the data of accelerometer and magnetometer, guiding the motor control for direction and auxiliary power.              ...

During the past week I have been solidifying the design and spending lots of time scouring the net for parts and scrounging locally. Although I have a pretty clear picture of what I need to do, I am having significant problems finding affordable parts. I need things like high torque gearboxes and large structures that can withstand high winds, and they just are not cheap, especially since they must look good. Consequently, the design is going to have to adapt to whatever I can find. Somehow it i ...
The Design This device is fixed on one side of injured elbow, Accelero/Magnetometer, The sensors can provide the motion status of arm, with pattern matching arithmetic, the direction and force applied on the actuator shall be calculated and timely modulation for PWM control on motors. This can add extra power for arm movement and improve the life span for injured arms. Of course, reduce pains if the elbow is still not healed. This is one kind of health care assistance machine, with gesture sensi ...
1. FRDM-KV31Fis supported by GCC, Keil, IAR and KDS. It is no doubt that Kinetis Design Studio is first choice. Updated version is 3.2.0 now.

A few things to consider with this project: 1) The motor is too fast - a stepper with a gear reduction would be a better choice 2) The motor is heavy - will probably move the motor to the mounting end of the main arm and use a belt or wire drive to actuate the folding arm.   I've been taking apart some old printers looking for appropriate gear components.  A nylon worm gear 1:100 would be perfect. ...

Description of the Device This device is fixed on one side of injured elbow, Accel/Gyro sensors fixed on this side of equipment can provide the motion status of arm. With pattern matching arithmetic, the movement of the arm is calculated. Base on the results, the direction and force applied on the actuator shall be calculated. Converted signal triggers PWM control on motors. This device can add extra power for arm movement,  and reduce pains if the elbow is still hurt. Original design h ...
Background Several months ago, my wife had a bad fall at her workplace which shattered her wrist, requiring multiple surgeries to repair, complete with embedded steel plates. As a result she has been forced to retire early, but it could have been worse and the next fall could definitely be worse. Almost half of all injury-related deaths among seniors in Canada are caused by falls. The cost to those individuals is the ultimate - their life, but the cost to survivors is also huge in terms of suf ...

Prelude Disability due to illness or aging should not be a limit to express the feelings and the emotions. And one of the preferred channels our soul communicates out is through art. People with disability may have several ways to express their art, but the most impressive form of art is, in my opinion, visual arts, like painting and drawing In this challenge, I'd like to give everybody the opportunity to draw   Architecture The project will be made up of two main components a eye tracke ...

Item Elevator Models

Posted by troush118 Apr 11, 2016
So since I made my introduction to my ideas I started with 3D models and brainstorming which would be the best way to set up this project. After many hours of sitting at the computer starring deep in the nothingness on my computer I think I have found a good way to approach.   The picture immediately below you can see a 3D model of a general shelf of similar shape as to what I would like to create.       The shelf I will be using is roughly 30 inches tall, 21 inches wide ...
It is only when you are directly impacted that you can realize that very simple daily acts are sometime virtually impossible to realize for people with disabilities.   I realized that when my young daughter, who is suffering from a neuromuscular disorder, started to draw. She had enough strength to draw but not enough strength to take caps of from her sharpie markers. This quickly became a source of frustration for her.   People suffering from neuromuscular disorders (e.g. SMA) have ve ...
Good day , welcome to the Smart storage blog.   Firstly I would like to express my thank and surprise to the organizers for choosing my entry, so here goes: The problem: I follow a widely practiced storage philosophy: place it on a flattish surface. This philosophy had a few floors (see what I did there), firstly there is fairly limited amount of flat surface in your home/office, secondly flat surfaces are by definition distributed in a horizontal plane, meaning that most thing you sto ...

Installed Software

Posted by armour999 Apr 9, 2016
Why not install the software while I'm waiting for the Kit to arrive ! The kit will include the FRDM-KV31 and FRDM-MC-LVPMSM. I am using a Acer laptop with Windows 10 installed.  NXP provides a robust library of software and information to support the FRDM-KV31. I might as well troubleshoot any issues with the software now. I think these may be the tools I need so here is a summary of the installations. For this blog I am using only screen shots until I have the hardware installed. Once I h ...
We were asked to submit a blog introducing our concept while waiting for the kit to arrive. It took me a long time to come up with some idea. Including a motor made it an interesting challenge. I have a friend at work who is legally blind but with special software is able to work as an IT Analyst. We talked about ideas for quite a few days but only could come up with ideas for canes that did not include a motor. Just about every idea I came up with included sensors but no motor.   So I beg ...
Well instead of beating around the bush about what I am creating for this challenge; I will be going over a very brief overview of my design idea.   Very Brief Overview:   For this challenge I am designing a system to mount on a cabinet (cupboard) that will allow elderly, handicap, and even just vertically challenged persons get items off those "out-of-reach" shelves. Be it you are handicap, elderly, or even just short this device will allow them to feel better because they will not ...
