Some vendors sell Arduino Nano boards with non soldered pin headers for much better prices than the soldered pin headers version. If you enjoy the delicious smell of solder smoke, it is a nice opportunity to practice soldering skills and save a few bucks to buy an extra Arduino board. The video shows three Arduino Nano boards being soldered, using a mini protoboard (breadboard) as a support for the pin headers, very easy soldering exercise.

This video shows the results of ballistic coefficient calculated using data gathered from projectile velocity measured at muzzle of an AT44 .177 and at a distance (two chronographs were used). The AT44 velocity was adjusted during the measurements, varying from about 800 to over 1,000 fps. Did the resultant BC values changed along velocities?

Two simple patches using a quadrature LFO: in the first patch, the four quadrature sine waves from the LFO modulate four VCO whose triangle wave outputs are spread through the stereo field.
The second patch is a four VCO drone with the saw wave outputs filtered by four lowpass VCF, modulated by the quadrature LFO four sine waves outputs, also spread through the stereo field. Ommmmmmmmm.
Another, more elaborate patch using quadrature LFO and a quadrature phaser to implement a frequency shifter, can be found on this channel on other videos (search "frequency shifter" and/or "IQ modulation" (In-phase - Quadrature).

An 8x8 sequencer, very basic in its features. The interface is composed of two rotary encoders with switch, and a 128x64 I2C OLED display.
The display presents an eight rows x eight columns grid, rows are steps,
columns are tracks. Encoders are used to navigate through the grid coordinates.
The X encoder switch selects Cursor or Write mode, in Cursor mode an 'x' is
shown on the grid and a 0 is written in the selected slot in a bi-dimensional
array, in Write mode a filled square is drawn on the grid and a 1 is written
in the selected slot in the array.
The encoder Y switch has three modes: Edit, Tempo, and Play. In Edit mode
the sequencer pattern can be created, in Tempo mode the Y encoder sets the sequencer BPM (Beats Per Minute), in Play it plays the pattern.
The right side of the display shows the BPM and the current mode, the left side shows a rectangle indicating which step is being played.
Each track fires a gate using eight Arduino pins (0 - 4.7V) and also sends MIDI notes through TX pin (channel 10, GM drum notes 35, 38, 42, 46, 45, 50, 64, 76). It works, but the display is too small for my eyes...
Schematic in the video, Arduino code in a pinned comment.
