A year ago, former #Oprah TV talk protégé, turned #MAGA minion, Dr. Phil was flying high amidst partnering with #Christian programming empire #Trinity Broadcasting and launching his own media #network... a year later, he's buried in #bankruptcy and blaming his former partners...

#Variety spills the tea at the link...

The jist of the tale is Phil MacGraw's on-air programming never found carriage on any major platforms like #Hulu , #Comcast or #YouTubeTV , and his #OverTheAir programming went from exclusives from the Professional #BullRiders & #NancyGrace to tired low rated reruns of old Dr. Phil episodes. Last year the Bull Riding Network pulled out abruptly, moved to the #Fox subscription platform and is now suing #DrPhil for failing to pay his #AltRight rights fees.

In fact, tone of the article documenting the multiple failings and fading popularity of Dr Phil make him sound like kinda beaten alpha male loser that would go on the Dr Phil show to talk about his many embarrassing #Texas sized probs to Dr Phil

Broadcast TV Simulator Keeps the Nostalgia Flowing - Watch out, Gen X-ers — there’s a nostalgia overload heading your way, courtesy of ... - https://hackaday.com/2024/09/26/broadcast-tv-simulator-keeps-the-nostalgia-flowing/ #homeentertainmenthacks #classichacks #raspberrypi #overtheair #broadcast #goldenage #antenna #rotator #70s #tv

Content owners are being incredible dicks with ATSC 3.0's DRM. (I know, it's a shock.)

It's bad enough that LG has stopped making ATSC 3 tuners.

If you care about the future of over-the-air television even a little bit, you might watch this and contact the FCC with opinions.

Woohoo! This time the #DTV antenna is working great and gets me the channels I need so goodbye #hulu and especially goodbye to paying money to any streaming or cable service that includes #FoxNews . Good f-ing riddance.

Optical Theremin - Demo

https://shkspr.mobi/blog/2012/06/optical-theremin-demo/

At Over The Air I demonstrated what I considered a novel use for one of Android's sensors. I wanted to create a Theremin - a type of musical instrument which is played by moving one's hand over it - changing pitch and tone by moving nearer or further away.

My first attempt used the proximity sensor. However, on all the Android phones I tried the sensor's accuracy was binary - it could sense if something was close by, but not say how close.

So, what else could I use to detect how near or far a hand was from the screen? I decided to co-opt the Light Sensor. This is normally used to automatically adjust the brightness of the screen - making it easier to see in strong light.

When the light sensor is uncovered, the total lux (that's the measure of light) may be 100. As a hand moves closer to it, that value will dip until it reaches 0 (or, on my phone, 4).

We can then represent that light value as a sound - essentially transforming lx into Hz!

This is what is sounds like

Your browser does not support the audio element - download the track.

Beautiful, I'm sure you agree! You can hear an interview where I discuss this app with the BBC's Jamillah Knowles on the Outriders Podcast (22m 50s in).

💾 Download this audio file.

If you want to have a play with it, the Optical Theremin Demo is in the Google App Store. Do note, it was coded in a couple of sleep deprived hours, crashes when you exit, and can produce "music" which scares children and animals. You have been warned!

Use The Source, Luke!

I've included the full source below, but I'd like to pick out two points which may be of interest.

Getting The Lux Value

Firstly, we need to register a listener for the light sensor.

@Override public void onCreate(Bundle savedInstanceState) {   super.onCreate(savedInstanceState);   mSensorManager = (SensorManager) getSystemService(SENSOR_SERVICE);   mLightSensor = mSensorManager.getDefaultSensor(Sensor.TYPE_LIGHT);   mSensorManager.registerListener(this, mLightSensor, SensorManager.SENSOR_DELAY_FASTEST);}

Every time the light sensor changes, this method will be called. It takes the light value and performs a simple mathematical transformation on it (adds 10, multiplies by 5). I found that this gave the most pleasing sound - but you can adjust it to your tastes

@Override public void onSensorChanged(SensorEvent event){   if (event.sensor.getType()==Sensor.TYPE_LIGHT){       mLux = event.values[0];       freqOfTone = (mLux +10) * 5;   }}

Cum on Feel the Noize

So, how do we get Android to generate a tone? I faffed around with this audio generating code from StackOverflow until I could successfully generate a tone.

Essentially, this creates a WAV of a tone and gets it ready to play.

However, this sounded rather boring, so I added some reverb.

audioTrack.attachAuxEffect(EnvironmentalReverb.PARAM_DECAY_TIME);

And that's it!

Download the Optical Theremin Demo App - or use the source to create something much more melodious.
