Kicad Vs Eagle PCB

I have been using the Eagle PCB for quite some time now for my PCB designs. It is very easy to use and there are many libraries and projects that can be downloaded on the internet. But due to some changes on eagle that made recently, I decided to switch and look for better alternative. Upon searching, I found this software called Kicad. It seems promising, feature packed and best of all its free!

Arduino Controlled Bass Treble Volume and input Selector

Last time I have posted about how to control the LC75341 IC using arduino nano. And I also posted about how to modify the bass response of the LC75341 IC. This time I will be building a home amplifier for my TV, it will also feature a bluetooth reciever so that I can play via my phone.

LC75341 Bass response modifications

Last time I have a blog post regarding on how to control the LC75341 tone control using arduino. I never really tested the performance of that IC until recently I got time to play with it. My initial impression was not good. The bass sound seems very thin and I can’t get the “boomy bass” sound that I wanted. Maybe its just me but the bass sound is thin compared to my little JBL flip bluetooth speaker. By the the way, the kit was from E-Gizmo’s digitally controlled tone control. I have investigated and model the circuit of the LC75341 tone control for simulation and the simulation results confirm what I am hearing.
