Its yet another tech weekend for me and Kaushani. This time we have come up with a hobby circuit called the “Audio splitter” specially meant for laptops as we’ve taken the power supply from USB. Its implemented using TDA2822MDual OPAMP IC with internal feedback which gives a gain of 89 (39db).
It has separate volume knobs for each headphone(o/p) as you can see in the photo below,works on a 10mA current.Its based on a prototype designed by Vasuki Prasad,an ex MIT,Manipal student.
Main features:
1. Power supply from USB (5 Volts)
2. 39db gain and low noise (A bit of hiss sound when fully amplified)
3.Separate volume knobs to control volume of your choice on each o/p.
Ever Green rocked MIT with Deep Purple’s Perfect Stranger in Revels ’09. While the crowd was ponderously waiting for the problem with the equipments to be laundered,they came like a fire and swept the air around to a cyclone of thrills. Heretic was supposed to come but they didn’t turn up due to some circumstances. However, Ever Green expunged all the depression and kept the crowd alive. According to organizers, Opeth will be a wonderland for the next Revels.If it goes fine it will be awesome.So to all the music fans listen to Evergreen’s latest hit “Altar of Dreams” .
Eastern Battle of Bands is a part of “Revels” , a cultural fest of our college. It was held on 4th of March this time i.e on the first day. We were told that there won’t be any such event this time as there were no other bands and later told us (Zehen-thats our band) to give a half an hour performance.Just before the registration in the morning we got to know that a Band from NIT-K was coming and we got so excited as we were told that the competetion was on again.
Later in the evening while we were back stage another band from MIT turned up and we thought yeah…its gonna be fun now! The first band performed was from NIT-K.Inspite of taking so much time in sound check they managed to do pretty good.There were couple of moments when there music went so messy but i truly agree its because of our Marshall MG series amps (worst and cheapest of its kind).
Then it was our turn and we performed three songs.First one was ‘Khidki’ by Raghu Dixit ( Its a new band coming up with a project known as the Raghu Dixit project).Second was ‘Bande’ by Indian Ocean.I think the crowd enjoyed it and the last but not the least was ‘Nayan tarse and Emotional Attyachar ‘ from DevD.

And then the third band performed which i missed as i went to
have dinner.Later i was being told that we have actually WON
and there were two winners. We had to share with the band
from NIT-K.It was a awesome experience and with Rs 8-9K we
have now got enough budget to purcase our new Bass Guitar.
Me and Kaushani were reading the tutorials on Tkinter (its a GUI module in python for those who don’t know) and we thought of writing a simple Cross’n'Not game using that.We are just so called ‘Bathroom Coders’(plz don’t take the literal meaning) and so our code might seem a little inappreciable to the regular coders.Therefore, we firmly welcome recommendations,comments and suggestions wherever needed.
Here’s the code forCross ‘n’ Not V0.1 or you can even download from the link given at he bottom of the post.
P.S. Few exceptions will be raised when you terminate the application.Kindly bear with it as we are currently working on it and will come up with a better version very soon .Suggestions are always welcomed.
Thank you people....
