Burdens shared are often easier to bear than burdens borne alone.
Ah, the "there is no such thing as altruism" argument. But perhaps reward and benefit transcends a single individual:
Tin whiskers usually don't occur with most solders, are solders are formulated to prevent them. Perhaps this is defective solder, or there was a high thermal gradient, or repeated heat cycling has fractionated the alloy?
The GPIO engine is a simple state machine that can be programmed to implement high-speed data transfer, digital video output, and many other purposes. It is one of the best and most innovative features on the Pico.
It's going to be like hypnosis. "When you wake up, I'll say the magic word Abracadabra, and you will believe you are a chicken and cluck while waving your wings."
Maybe the Sikh said the prayer to deliberately provoke the reaction to show the Republican's hate, as if it wasn't already understood.
I think manufacturers need to get a lot more creative about simplified computing. The RPi Pico's GPIO engine is powerful yet simple, and a good example of what is possible with some good application analysis and forethought.
I made myself a 3-D printed drain cover
https://github.com/profdc9/FreeCADParametricModels/tree/main/Sink-Drain
And it traps the hair and I don't have problems with clogging. It's a parametric part so it can be adjusted for most drain sizes.
Computers are only at fault when its convenient to blame them.
The envoy had probably never seen clean water before and wanted a closer look.
Yes, everyone wants to see the Republican circlejerk.
In my house in North Carolina, I put up radiant barrier foil in the attic. It was cheap and made a huge difference in the upstairs temperature. I stapled it to the joysts so there was an air gap on both sides of the foil, and so that the hot air would rise out of the roof vents.
I had a nice pergola at another house I grew grape vines on. I sure do miss it.
The average Congresscritter doesn't need to hoard gold bars in their house. Today influence peddling is only slightly more subtle.
I really think that Musk is like the modern Citizen Kane, and we need a new Orson Welles to show the depths of his depravity.
It's going to be the Night of Long Knives or Stalin's Purge all over again. Trump will terrorize and purge his own party to obtain absolute control.
TrebleSynth
I create an open source software modular synthesizer out of a Raspberry Pi Pico. You can see a video on it at https://www.youtube.com/watch?v=252Vte4tYh0
My wildflowers were mowed down!
Last week my landscaper mowed down the mostly perennial, but a few annual wildflowers I was growing from seed. The landscape thought they were weeds because they were mostly not flowering yet (and there were a few weeds in there as well). So now what do I do? I have been watering it every day to see if I can grow some of the plants back. I put a lot of seed down, I hope something will last.
Creating a self-contained binary
fldigi repository with SCAMP. Contribute to profdc9/fldigi development by creating an account on GitHub.
I have a program (fldigi, pointed to by the github link) that uses dozens of shared libraries. I would like to be able to distribute a pre-compiled version of the program for testers. I could require each tester to install the shared libraries and compile the program for themselves, however, this would be extremely difficult for most users. What are some options for distributing a pre-compiled version of a linux program? Do I need to make a package for common distributions or common versions of each distribution? How about snap, nix, or flatpak? I don't have much experience with using docker or preparing docker containers, and the particular program (fldigi) requires access to system hardware to function, which a containerized version would have to accommodate.
This is going to be a temporary solution and I hope once the program is done being tested, my changes can be pulled upstream and then distributions will include it that way.
Eclipse Poster
I made a poster of my eclipse photos taken in southern Illinois. The PDF of the poster is downloadable as a 24 by 36 inch poster.
Is this a boondoggle or is it actually useful investment?
EPA News Release: Biden-Harris Administration Announces $20 Billion in Grants to Mobilize Private Capital and Deliver Clean Energy and Climate Solutions to Communities Across America
It seems to me these giant grants to a small number of organizations (Climate United Fund, Coalition for Green Capital, Power Forward Communities) seems like it could be delivering pork to well-connected people. Is this actually going to produce "clean" energy and help disadvantaged people? These seem like very large awards to a small number of organizations.
Planting perennial and annual seeds together?
I would like to get plots started with perennial flower seeds. However, it seems like the weeds will overgrow the plots while the perennial seeds get started.
Could I mix perennial and annual flower seeds and have the annuals try and crowd out the weeds while the perennials take root and come back next year more strongly? Or will the annual seeds prevent the perennial seeds from growing?
A most unusual place to demonstrate a woman's right to choose.

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

GuitarPico
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.

Guitar Pedal
A guitar effects processor based on the Raspberry Pi Pico - GitHub - profdc9/GuitarPico: A guitar effects processor based on the Raspberry Pi Pico
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.
