Here is a simple stereo headphone mixer that can be used for monitoring and mixing 2 sources. A very helpful device for online streaming. How? For example you are playing a keyboard on a band in an online stream and using a headphone as monitor. You can use this to mix the headphone output of you keyboard and headphone output of the streaming mixer so you can hear more of your keyboard.
If you are looking to control your audio with arduino, here’s it is. It uses TDA7419 chip which has a lot of features for controlling your audio. It has 4 input selector, bass control, mid control, treble control, loudness control and a built-in 7 band spectrum analyzer.
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.
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.
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.
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.
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.
