This Twin Audio Visualizer is nothing other than amazing. It includes a Teensy microcontroller board that drives 2 displays simultaneously at a very high speed. Combined with a Teensy Audio Board, it is capable of doing a frequency analysis of the Audio in realtime to create a Stereo spectrum analyzer of 69 Channels.
Yep you understood me correctly! 69 channels in stereo…so that’s actually 138 frequency bins. On top of that, we will be displaying a stereo VU meter on the second display.…

Got my pcb proto ready. This is a Audio Visualizer that will be available as open source. It has two display. The first display will show a stereo VU meter, the old fashion way: imitating a needle.. while the other display has several features one of those is a stereo 69 channel spectrum analyzer…and it’s really fast! so that’s 140 channels in total! ( L+R VU, L69 +R69)
The pcb will include hardware to implement line in, line out, mic in…input for potmeters and switches and two outputs for pixelled matrix or ledstrips………..So…

The last two years, I have been designing and building Audio Spectrum Analyzers and I sold more than 100 PCB’s. This means that more than 100 units where build successfully. I asked people to send in a video of their analyzer while playing a specific song. This video shows a compilation of some magnificent builds. It contains several versions from my oldest, the 14 channel MSGEQ7 analyzer to my newest, the 10 channel analog analyzer and everything in between.…

White Noise
This is the most common and well-known form of noise. White noise is comprised of an equal amount of every frequency, all played at once. It happens in real life when your TV or radio makes static noise. However, because of our ears’ frequency response, we perceive higher frequencies as louder, so it doesn’t sound particularly balanced to most people.
Pink Noise
Pink noise is essentially bass-boosted white noise, where the amplitude decreases as the frequencies get higher.…

This Talking Clock is based on @Brian Lough Tetris Clock. I added a wav/mp3 player enabling you to play sounds at set times. I also added a webserver to change settings, two text tickers to send you message out to the people in the room and I included a function to use this clock even without access to a WIFI network. All in all, I added some extra features to a already nice design.
This video is sponsored by @PCBWay They make great PCB board and offer good assembly service.…

This is my digital version of an old riddle. A Farmer needs to take a Fox, a chicken and a sack of grain to the market. On the way he needs to cross a river in a small boat. In the boat there is only space for the farmer and 1 object a time. Without supervision, the Fox might eat the chicken or the chicken might eat the grain. How can the farmer get all items to the market? Depending on what country you are in, the version of the story might have different characters.…

To explain about his Talking Arduino Timer, Imagine working at the office from nine to five punching numbers in a computer the whole day…All you have, to hold on to, is your coffee break! Fortunately, it is not that black and white for most people. We do have something in common though. There is a time that each and everyone of us needs to take a bathroom break. At some point, all the coffee we drink needs to leave the body, doesn’t?…

Make music with this Stereo flyback ZVS driver. You can drive 2 flyback transformers to create a 2 channel sound ( Stereo ). You can use square wave music as the sound course.
It’s a fun little project that you can use to create awesome videos. Also, you will learn how to drive Flyback transformers; a technique that was used in old TV sets but if becoming less and less every day.
You can use any flyback transformer that you would like.…
