SMPS-PSU Hack

Using a Standard Computer SMPS and Making a Decent Powerful PSU from It 


Power Supply for LED projects or Power hungry projects can be pretty challenging especially when you want to try out if your IDEA works. 

Further, PSUs can be really expensive. So, In this project I built myself an decent 450W PSU using old Computer SMPS laying around. I added USB so that i can even test out SBC’s, etc. 

Specifications:-
10x 5V 30A (Shared) Output [0.1” Male  + Female header ]
2x 5V 30A USB Output [0.1” Male + Female header ]
10x 3.3V 28A (Shared) Output
8x 12V 20A (Shared) Output [0.1” Male + Female header ]
4x -12V 0.8A (Shared) Output [0.1” Male header ]

Input: SMPS 240V 450W

P.S > HIGH POWER THRILLS BUT KILLS. Be Aware of what you are doing.

Smart Bike Smart Rider (SbSr)

Sponcered By Element 14 Community as part of IoT On Wheels Design Challenge


SbSr is not just a IoT project but a assistant or a personal touch that you own bicycle will give you. The concept is to make you bike more than just bike, more like a friend.

The genesis of the project comes from a overall shift in trend towards motorised vehicles rather than riding bicycles. Bicycles are now a small community of riders who enjoy riding or a a professional community who train for excellence.

There is a overall shift in fitness trend with introduction to Smart Wearables like FitBit, pebble, Xi Band, etc. But still, If you want to go to gym, you most probably would go on a motorbike or a car, even if its just half a mile away.

This project aims to take the best of technology, gel it together and make a product which would help start a trend of biking (as another fitness measure) just as the Wearables Electronics did, Fitness trend.

Wireless Pen Drive 

Wireless Memory Stick based on Linkit Smart 7866 Duo


What's more fun than getting rid of storage devices occupying my damn USB ports ( @all MAC users You know What I mean ) 

The IDEA was to make a Portable Battery Powered Small Module that I can add memory to and access the memory remotely over WiFi or while connected to my router. 

So there are many wireless storage devices like SanDisk that costed me about 3K INR !! hey but where is the fun of learning there ?
So, I went with buying a Linkit Smart 7688 Duo Board that costed me about 1.6K INR and as I already had a 64 GB Memory card laying around. While I used 2 18650 Batteries I extracted from a damaged old Laptop battery :) 

Specifications:-
1x 64GB Class 10 (90Mbps+) Micro SD Card
1x Linkit Smart 7688 Duo Board 
2x 18650 Li-Ion Batteries
1x Battery Charging Module With Protection Circuit

3x3x3 LED Cube

Fun project to demonstrate Modular Electronics 


This was a quick-fun project I did within an hour, just to play with the LED's and to show a concept Modular Design. The design is broken into LED cube section as well as a MCU (Control Unit) section. The LED section can be used as a generic module with any development board. where the control section can also be used generically.
Finally, I think this is a perfect project for people who are starting in embedded and definitely a Embedded C refresher/ learning exercise. :)

Specifications:
27 Blue LEDs configured in 3x3x3 fashion
Msp430G2452 used as application processor

Smart Commode

This was a project made as a pert of Intel-IoT Hackathon in Bangalore India (Quarter Finalist)


Project SmartCommode focuses on Informing people about health of their kidneys by monitoring parameters like Renal Stress, Renal Failure and Cardiovascular stress based on the conductivity of Urine. An average human has an conductivity of ~21mS but in case of renal stress that value may go beyond ~30mS which, if regular, means improper function of kidneys. Smart Commode is an small add-on module that can be fitted in any of the public toilets and will start measuring the conductivity, color (Work in Progress), temperature (Work in Progress) and PH (Future Work). The above information is logged on Cloud which will run basic data analytics.
In future users will also be able to see their kidney's health directly on their Bluetooth Smart enabled mobile phone.


Specifications:
Intel Edison Board
Custom made fluid latch and release mechanism
Custom made cheep Sensor Probes
LED + Sound indicator for people

SBC-IoT

An IoT Edge Router/ Node Using Beagle Bone Black SBC


The aim of this project was to make an IoT Node out of a Single Board Computer. Many IoT applications need a sensor node which can store data locally, run some local data analytics and display data on some LCD module but meanwhile be connected to cloud and also be able to connect loads of sensors and other devices. Well, I thought the best candidate for it maybe a cheep user-friendly Single Board Computer. My choice was a 45$ Beagle Bone Black.

My First attempt at Energy Harvesting 


I made this prototype for understanding and experimenting with the plethora of free renewable energy available to us. The Prototype used 2 6v/300mA solar cells to deliver 5v/500mA for charging cellphones. I was able to get 5v/650mA at peek noon time and about 5v/200mA before sunset. I was successfully able to charge my mobile and could even run RaspberryPi using the power source.

Linear Breadboard Power Supply Unit

My attempts at BreadBoard Power Supplies 


I try to make many of them as they are really important for my breadboard projects. The first prototype I made was a breadboard plug-on power supply unit. Powered by 7v/3000mAH power supply unit. Later I made a smaller Power Supply Unit(PSU). Both of them have Linear regulators from TI, filter cap and protection diodes for reverse polarity. Currently there isn't any short circuit protection, but I have plans to add that in my next prototype.
