Topic: Electronic component purchase, testing and interfacing Yesterday my whole day was spent on S P Road, Bangalore for component and accessories purchase. After spending 3 days for purchase I could get the bare minimum. I am using LM35 for temperature sensing, IRF830 MOSFET for current control of the heater. LF356 op-amp for scale changing of MOSFET gate input voltage. The DAC is giving the analog voltage of 0 to 3.41 volt. The threshold of MOSFET varies from 2 to 4 volts according to dat ...
Sadly, this great contest has come to an end.  This leaves the SteadyClip project unfinished as of right now.  I’ve had a great run, but I truly do need additional time to fully understand the microstepping of motors to get a complete design.  Right now, the motor drivers are functional and I am capable of accessing the IMU.  Eventually, this project will be complete.  When that happens I cannot wait to show it to the element14 community, and the rest of the intern ...
So here I am at the end of the Smarter Life Challenge, and I am happy to say that I had a lot of fun and satisfaction along this time.  Starting from a "crazy" idea to control appliances by brainwaves, things became more and more realistic up to the point of building a prototype that worked.  As I showed in the last update videos I was able to turn on and off a television set, a cable box, and I was able to change channels by only moving my eyes.  It all happens from the brain dec ...
Doug Wong Back to Doug Wong's VCP Profile   |  Smarter Life       Objectives The Smarter Life Challenge was intended to showcase PSoC4 technology and the Henrietta project addresses this requirement, demonstrating the kind of complexity that a PSoC4 can successfully implement. It does this with completely exposed but attractively mounted circuitry and subsystems. Additional objectives for me were to learn about the flexible and powerful PSoC4 architecture and the p ...
The Henrietta system is mounted in a picture frame to showcase all of her circuitry. She uses a servo motor to lift the window in front of her picture frame to provide access to the touch pad. The servo feature was included in the project to demonstrate how easy it is to control a servo motor from the PSoC4.   Servo Motor Demo Video The following video shows the servo motor in operation. There is also an oscilloscope to show the pulse width modulation waveform through the various position ...

Intelligent Wheelchair:

Posted by vu2iti Jan 13, 2014
My Wheelchair project needs obstacle detection along the travel path of the wheelchair. It is also needed to see that the floor is even and to detect stairs and dead ends of the floor for safety.  Three sensors are planned for this purpose. The positions of the sensors are as shown below: Figure 1. Wheelchair Sensor Positioning Ultrasonic forward looking obstacle detection Forefront obstacle detection is based on the reflection of ultrasonic pulses emitted from the ultrasonic transduc ...

Hello all,   Update on the complete challenge Here are some posts to get you started if you jumped into this challenge, and didn't get the full context: Smarter Life Challenge Competitors (thanks Joseph Man!) Review of first design week! Overview - week 2 of PSOC Design Challenge Overview, Week 3 and a bit Overview, week 4 and a bit Overview, week 5 Overview, week 6 Overview, week 7 Overview, week 8 and a bit Overview, week 10   !!ONLY 5 DAYS LEFT FOR VOTING!!

This posting presents a video demonstrating remote control of the Henrietta hardware from an android phone via Bluetooth. The android app was programmed using App Inventor, now managed by MIT. To keep operation as simple and intuitive as possible the app covers the whole screen with control buttons, avoiding hidden functionality behind scrolling and menus. All controls are always visible. This app does not display information like the PC app - but all information is displayed by the Henriett ...
If you like my project vote for "A Smarter Tricopter - Yuri Tikhonov"   Good day comrades! 1. Earlier this week, I was doing final preparations for the tricopter's flight. TODO list included: Firmware: many small but critical changes; Rx: completion of wiring; Tx: battery replacement; PCB: repair of a defective LED; PCB:  soldering of supply conductive tracks; ESC: brakes off, "Quick Start" on, etc..; ESC/BLDC: three-phase wiring soldering; ESC/LiPo: checking all units of t ...
Modular Panels    I have just prototyped a modular 8x8 LED matrix board. To show you how simple the wiring is I have made it on a single sided PCB. These panels can be joined together to form a larger display, chained together or be used individually. The video is of a scrolling background test. The background is set up as a wraparound cylinder with the LED display showing a selected portion.   The photo shows a mostly weeded board. The red circles highlight the dregs yet ...

Topic: PID in hardware Keywords: Op-amp, differentiators, integrators, simulation, TINA-TI For implementation of PID dual-supply op-amps are required. A positive supply op-amp can be used with the input given at the non-inverting terminal. In that case, the output is PI and PD for integrator and differentiator configuration respectively. But if the function slope is less than 1 the output tries to become negative for a differentiator. For a positive supply op-amp this gives a zero or err ...
It's been a while since my last update, I've taken a little break over new year, I did however find some time to write some code. It's pretty much all done bar managing the charging state and some power saving. I've taken my time to do this properly with a clean HPL layer and enough abstraction to make tuning easy.     The video shows a few different things, first the light coming on in vertical (rear light) mode after some 'movement'. Then it turns off after a timeout, with the lam ...
Do you ever feel like you're going around in circles?    This is just to prove that the LEDS on the Light ring are individually addressable and working. The speed of the chasing is varied slightly in the video. Variations of this simple theme can be used for lighting effects. You can chase one LED, some LEDs, all LEDs, use sectors, change colours and control brightness. You can even add various triggers such a proximity sensor.   I could even build a Solar system model wit ...
