Maybe Trump should have mooned Harris. Then it would have been even more memorable.

I have lived in several counties in Illinois and North Carolina. They have been urban or semi-urban counties. I have never experienced any problems voting anywhere I've lived. In fact, it seems like they bend over backwards to offer every option for voting. I am much more concerned about gerrymandering and effective bribery of elected officials using campaign donations.

It's a great line, but it's also kind of tragic that these kind of soundbites are how we decide who is commander and chief of the armed forces.

If they don't blink and you hear the servos whirring, that's a pretty good sign.

In other news, they interviewed 200 historians and by chance found one that happened to predict 9 of the last 10 elections correctly.

Knowing the media, not being able to say anything coherent is a benefit for him, because unlike Harris, nothing he says can be construed as truth, a lie, or anything sensible. If Harris says something that could be even slightly wrong, she will be pilloried, while Trump will be excused because he is senile.

Gravity is not instantaneous. It moves at the speed of light. And the "speed of light" can only be measured locally, because the time and space at a point are curved. The path of light corresponds to "null geodesics" in spacetime, and a body traveling along the geodesic experiences no time elapsed.

The only material changes I can see would be for Russia to move nuclear weapons into occupied Ukraine and/or resumes nuclear testing. Every other escalation does not result in a change their stance that can be perceived from outside Russia. Either of these events would cause an enormous elevation in the readiness and deployment of NATO forces and would risk uncontrolled escalation. How desperate is Putin now?

The system can be overwhelmed by having too many incoming rockets, so it does have its limits.

It means that the key is stuck.

 

This is a demonstration if the GuitarPico's effects. The GuitarPico is an open source effects pedal. The hardware and software is available at

I'm having so much fun making this I thought I would share.

I am working on a simple, cheap, easy to construct multi-effects guitar pedal based on the Raspberry Pi Pico microcontroller. All of the other parts are generic parts. So far I have implemented the following effects:

Noise gate, Delay, Room, Combine Effects, Bandpass Filter, Lowpass Filter, Highpass Filter, Allpass Filter, Tremolo, Vibrato, Wah, Autowah, Envelope, Distortion, Overdrive, Ring Modulator, Flanger, Chorus, Phaser, Backwards (play the last few samples backwards), Pitch Shift, and Octave (rectification).

Some effects can be cascaded inside the device. There are up to 16 "units" where each processing stage can process the results of the last stage. Various controls on the effects can be assigned to the four potentiometers at the bottom of the board, or two expression pedals you can plug into the side.

I also added a VGA output because I want to have a cool video display that changes with the audio. Also, perhaps implement some kind of guitarsynth or MIDI control.

Anyways this has been a lot of fun to make. I hope others will enjoy it too.

For the past few days I've been working on a 3-D printable footpedal potentiometer to be used in a guitar pedal. It is a parametric model in FreeCAD. It has a top and bottom that hinge together, with a potentiometer that is coaxial with the hinge so that when the pedal is pressed, the potentiometer is rotated.
