Graphical representation of Collatz conjecture depicting all numbers with an orbit length of 20 or less
Collatz Conjecture: Take any natural number n. If n is even, divide it by 2 to get n / 2. If n is odd, multiply it by 3 and add 1 to obtain 3n + 1. Repeat the process (which has been called “Half Or Triple Plus One”, or HOTPO) indefinitely. The conjecture is that no matter what number you start with, you shall always eventually reach 1.
Cavaillé-Coll organ of Notre Dame de Metz
This is a test fit of all 48 pipes on the wind chest. You can see the the normal wood pipes along with the bigger mitered pipes in the back. There are 11 metal pipes salvaged from the same organ which supplied the solenoid valves. I should be able to have some videos of the system playing in a few days. Luckily, I wanted the organ to be very modular so the organ has its own microcontroller (arduino) which reads a MIDI input and activates corresponding pipes. A second control computer will store and output the MIDI files to the wind chest controller.
We got these organ pipes from the Saint Paul Masonic Lodge this morning! If you have bare walls and are finding ways to enhance the look and feel, try a unique design by hanging organ pipes on your walls. If you are into the pre-modern era look, assemble an organ pipe instrument in your home. Pipes sold at $25+ at Architectural Antiques. Which look is your style?
It’s been almost a year since I finally made it to the Saint Chapelle. I thought of it today, because it was the first time this autumn that the air has been truly cold, just like back in January when I stood shivering, looking up into that warm light. Had a pretty awful day, dragging my feet from one failure to the next, but little things like this will help me keep my head up.
