Cheap DIY USB Audio interface for online streaming

In this new normal, most people shift to online content like seminars, meetings and specially churches.

Here is my current project designed to give you better audio for online streaming. It is basically a link to your analog mixer to your computer. It is also known as USB audio interface. What made it different to other products in the market is the integration of sliding fader for better volume control. For church online streaming, you have big volume difference between the band performing and the pastor preaching, the sliding fader makes it easy for such volume adjustments.

Simple stereo mixer

Here is a simple stereo mixer for you that can be easily built. You can mix 2 stereo sources.

About the Circuit

The Circuit is simple and uses only 1 opamp. This can be powered by a 12V DC or a 9V battery.

Using SNAT inverter Mode 1 for Solar

SNAT inverter has 3 modes, mode3 is basically used for solar power system and mode1 is used for UPS function. I have been using this inverter for more than a month on my home solar power setup and used it on mode3. But this mode 3 have some problems when using the inverters built-in ATS(Automatic Transfer Switch). This is the function where it automatically gets power to the grid when the battery gets very low.

My Home Solar Power project

I have been experimenting on solar power for years but it is only recently I decided to go full speed and spent big. I want to share this project so anyone who want to DIY their home solar power project can follow.

Our country has the most expensive electricity rate in the whole south east asia so, investing in solar power is a no brainer. Sure it is a bit expensive but ROI is only around 3-4years if you do it yourself.

Understanding Battery Balancing – is it important?

In the world of electronics, nothing is created equal. This is also applicable to batteries. A 10AH (ampere-hour) rated battery is not exactly 10AH in actual. This variation on capacity is a big problem when connecting battery in series because the battery with least capacity will be the first to full charge and full discharge. This is where you need a battery balancing circuit.

DIY Simple Cheap Automatic Solar backup power system for 12V System

Solar power is a renewable energy from the sun. But there are times that is raining for several days and during those days, our solar power might not be sufficient for our needs. On this project we will create an automatic solar backup power system to automatically connect to the AC grid when the battery level gets very low.

LM1875 120W(30W+30W+60W) 2.1 channel amplifier | Cheap and easy to build

Here’s a simple 2.1 channel amplifier for you home. it uses TI 20W LM1875 amplifier chip. It uses 4 of it so it can produce a total of 80W. It can output up to 30W with a bit higher THD. Maximum attainable power is 120W total.

Adafruit oled library problem Workaround

My latest project includes an OLED display with 128×64 resolution and 1.3inch size. In search for a library, I found Adafruit oled libray problem. The display does not seem to work with this library. Upon doing some research, I gave up and do this work around instead.

iRig Audio interface tear-down

Out of curiosity, I tear-down this iRig audio interface that I used sometimes to record my guitar solo. I didn’t expect the circuit to be complex since this device is cheap (must be fake), only cost around $3.
