This is my very first project when I was in college simply because it is simple and the parts are readily available. It can be easily built using breadboard or universal PCB because it only requires few components. It uses a very popular op-amp 741.

Audio signal clipping/peak detector
If you want to have an indicator for your amplifier that tells you that the signal is clipping then this is the one for you. This circuit can be used at the input or output of the amplifier. You just need to change some resistor values to make it work.
ATTINY817 UART with PuTTY
In this article I will show you how to use the ATTINY817 XPLAINED to communicate via UART using PuTTY software. This is very useful when you want to debug your hardware using your PC. This comes in handy if your hardware have no display and other means for human interface.
Simple Guitar Distortion Circuit
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.
