Ever wonder how many components is the least you need to build a simple distortion effect for your guitar? The simplest I can think of will need 8 components. This is so simple that you can build the circuit even without using a PCB.

12W amplifier with TDA2008 IC
This is a very simple amplifier that can be used for your room sound system, kitchen or even for home theaters satellite speaker. It only requires few components at a very small board. It can operate at 12V supply. It can be able to deliver up to 12W at 4 ohms and 22V supply.
60-100W amplifier project
I have been wanting to build an amplifier like this but I have no time to build it so I thought I can just share this design and let you readers build it. The design is pretty much similar to Elliott’s Amplifier design with very minor tweaks. As usual I always simulate my design with simetrix to validate that my circuit is working correctly.
Speaker Protection Circuit
If you are an audio enthusiast like me who loves to build your
own sound system, this circuit is a must. This will protect
your expensive speaker from burning in case your DIY amplifier
breaks.
Simple Solar Charger with Volt meter
Here’s a simple solar battery charger circuit that I used for more than 4 months now and still works fine. The circuit is very simple and easy to make with universal board. It uses the LM317 linear regulator for the charging circuit.
Simple Automatic Solar light
Solar powered devices are getting more and more popular these days. It is renewable and Eco-friendly kind of energy. One on the most popular application of solar power is the solar powered street lights. I made a very simple schematic of a solar powered light that can charge and turn on the light automatically.
Adding Rotary encoder and a button to arduino
This is from my latest project arduino-controlled-bass-treble-volume-and-input-selector. I only created a separate thread for the rotary encoder and button part just in case you only needed that part on your project.

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.
