Electronica!!

WOW it Looks like a CD!!!

Well when my dad bought a computer when i was in middle school....i was very fond and fascinated by this device ..............the first thing i did was play games....more games......well at that time the comp's config was too bad pentium 1, 32mb ram, and then no video card thats it... I was always curious about the CPU or the cabinet where motherbaord and all the components are present....so one fine day i opened the Cabinet.........i was totally blank i didnt understand anything what was there inside the cabinet .........and then gradually i asked my cousins who were studying computer science.....they told me not to open it again......but i became even more curious when i knew what was motherboard , what was harddisk.......well first thing i did was removed the hard disk............from the cabinet....and then i slowly opened the harddsk outer part.....well thats the picture what you are looking at the old hard disk which i had spoiled......well when i opened it i said "WOW it Looks like a CD!!! and then i fixed it back ..and finally when i switched on the computer......................everything gone my DAd's files had gone everything even my games.....music.....................Everything....................oh that was the first time i thought to never play with computer components...............After 4 years i.e when i was in first PUC ....i assembled a computer.

FM Transmitter:


Well this is one of my first projects which i did it when i was in high school.......its just a FMreceiver and transmitter. Well it took 3 days to complete it......because it was my first project and i wasnt familiar with all the components..........well it worked and then first thing i did was i broadcastd my voice...........it was a total fun for me .....and then i used it as an wireless headset.....for listening to audio while watching movies...............it was awesome at that time.......
Actually i first did this on a breadboard and then to PCB.
Regulator or 4v battery charger:



Ok well after a long break i built this regulator .....i had a torch which had a battery of capacity 4.2v ......it was rechargeable... i meddled with the torch finally i couldnt assemble it back so i removed the battery and i wanted to manually charge it.... i mean having my own circuit to charge this battery, so i built this one, it just gives 5v dc output...and it takes approx 10hr to charge this battery.......it was an awesome experience with this project as i got to know how to rectify the A.C input.......and also the FILTER part.......still i use this to charge that battery.

This is my ELECTRONIC WORKBENCH
