Today while i was cleaning my room i found old radio under my bed. I think its my dad. I was just sitting and suddenly something cameup in my mind. I was thinking if i could change .my old radio to iphonedock.
I used some spare parts that i found in my house like Arduino,speaker,amplifie and some led lights.
At first i removed old parts from it. After that i replace old speaker with new one. Then we add dock in it.
I use Fiio L11 from Parts Express to dock and get sound from it. It enable charging and get sound output when plugin.
I use TEA2025 amplifier circuit to amplify the sound.
I made the display by drawing it on my computer, then printing it out on a sheet of paper placed behind a plastic window. I used LED’s on the back to indicate volume and source selection. The LED’s is controlled by an Arduino.
The diagram for led
I have successfully turned my old radio into an iphone dock.
