Welcome to week 19 of the Design Challenge series here at Element14! This week is all about the Make Life Accessible Design Challenge which is in its fourth week of competition. There is a lot of progress being made across several projects, and...
This week was mostly pondering mechanical issues and doing some metal bashing, although I did do some more parts ordering as well. I managed to scrounge a very old bicycle which is small enough that I can bend the frame - with a little persuasion fro...
After installing OpenCV, we are now ready to install PyGaze.First of all, let's install all dependencies (some depencies may have been already installed, but let's stay on the safe side)In a terminal window , type sudo apt-get install python-num...
Welcome to week 18 of the Design Challenge series here at Element14! This week is all about the Make Life Accessible Design Challenge which is in its fourth week of competition. We had a flood of updates in the past week, most of which were ver...
As mentioned here, here's what I am currently thinking doing.- side 'back' wheels would drive in one direction- side 'front' wheels would drive in the opposite direction- side wheel would have to move towards the sharpie to produc...
In my first update, I've mentionned that 3 forces were needed. Obviously, I can't really use 3 actuators (1 motor and 2 linear actuators or 3 motors...), that would be overkill for such a device. Ideally, a single motor would have to be able ...
While waiting for the kit parts to arrive, I've been collecting possible assembly components including an old CRT monitor stand and some oak strips/rods/U-bolts/etc.The structure needs to be sturdy enough to handle the weight of the tabletop and ...
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 t...
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 consHeader 1Header 2Header 3The first ...
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-KV31FFRDM-KV31F is fixed to one part of the frame and MPU6050 shall be fixed in another one This is to provide ...
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 ...
1 What drives this design is the innovative product of and FRDM-MC-LVPMSM by NXP Unlike most of the embedded MCU which is fully functional and appropriate for almost every circumstances FRDM-KV31FFRDM-KV31F and FRDM-MC-LVPMSM specilized f...
1. Introduction to KMSKinetis Motor Suite (KMS) is a bundled hardware and software solution aimed at enabling rapid configuration of motor drive systems and accelerating application development. KMS includes firmware targeting the Kinetis V (KV) seri...
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 ...
Previous postsPost 1 - Introduction PyGaze (the open-source eye tracking software this project will be based on) requires OpenCV for python. Installing OpenCV 3 is a multi-step (and even time consuming) process requiring you to install many depe...
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 part...
The DesignThis 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 mod...
