This is my gift to manknd…
This is the power of the future. Not the ultra expensive tokamak nor other systems producing waste. Few years ago I forgot my tea in the kitchen.. With teabag still being inside.. I was like „ah, of course“.. The tea did drip over the edge.. And there was a new idea.. This principle feeds the trees with water and without it there would be no life on Earth. I believe that with proper nano material it will be the major power plant type in a few dacades..
LCD Font Editor
Embedded 3D Tools
And there is still so much to publish from 2020…
Magnetic field measure, portable PM tube power spectrum display with czech settings and sound, 8-bit sound pojects like drummachine trigger, loop player and more!!!
Whats next? Stay tuned!
I like the concept of this guy’s classics game version, but it could be coded better 😉
With some small modifications i was able to run it on SPI oled with Adafruit ssd1306 drivers with very nice performance. As first i took the version from part 10 because it doesn’t use modified interrupt based ToneAC library which would make (almost) impossible to compile for other arch/boards like Blue Pill or esp8266 based devices…
First i loaded SPI version into my DIY small oscilloscope called device 😀
I did like the game so i made it look overall better, slightly 😉
In future i would like to have code usable as standalone or as addition to other oled based projects where is some spare flash space left. The highest goal would be the ws2812 led panels/strips based arcade gaming machine.

Author’s blog post about using MoviePy to animate vector graphics here
MoviePy PyPi page here
Gizeh GitHub page here
..at PyPi page they state to install MoviePy simply by: pip install moviepy
..not that fast bro, MoviePy 1.0 runs only on python 3, so i had to use older version for my rusty old python 2.7.. sudo pip install moviepy==0.2.3.5
Successfully installed moviepy decorator imageio tqdm enum34 futures
Cleaning up...
well..that worked, but package itself uses lots of other packages to work..
..on Linux Mint 17.3 i went into dependency hell, have a good luck trying..
..to run examples i had to install gizeh..
sudo pip install gizeh
RuntimeError: cairocffi does not support Python 2.x anymore. Please use Python 3 or install an older version of cairocffi.
solved by using older version: sudo pip install cairocffi==0.9.0
trying to run examples from authors blog:
from moviepy.editor import *

"imageio.ffmpeg.download() has been deprecated. "
RuntimeError: imageio.ffmpeg.download() has been deprecated. Use 'pip install imageio-ffmpeg' instead.'
solution found here
sudo pip install imageio==2.4.1
problems with pillow setup:
had to manually install package „libjpeg-dev“ via sudo apt-get install libjpeg-dev or installation failed
another problem right on:
ImportError: Imageio Pillow requires Pillow, not PIL!
so i tried:
sudo pip install pillow
Requirement already satisfied (use --upgrade to upgrade): pillow in /usr/lib/python2.7/dist-packages
Cleaning up...
lol?
found issue: https://github.com/Zulko/moviepy/issues/748
being rather issue of imageio: https://github.com/imageio/imageio/issues/322
– yes, there is no pillow there 😀
oh really?
sudo pip install --target=/usr/local/lib/python2.7/dist-packages/ --upgrade pillow

would the example from author’s blog post work after all this? of course NOT 😀

YAY IT WOIRX NOW !!!
– plays mp3 files
– support for 32GB USB and 16GB microSD storage
– 3W/4Ω amplifier
– overall sound is not flat, it is probably intended to use with a speaker, low frequencies are dimmed and heights are boosted
– sound using KOSS porta Pro is clear, the underneath noise is very low, heights are very crispy, super fine
– USBs are okay, microSD card slot has push to eject mechanism
– the 3.5mm plug goes okay after few cycles, new has very tight contacts, not soldered well, not straight
++ sound quality
++ USB slot
— click in headphones when plugged in
— does not play wav files
status: initial version done and working, making 2nd version
status: first version done and been used for >year, making new version which will generate strategy as well, with animated simulation, all from scratch
status: display image done and feature almost complete(add invert), font creator needs new gui(but is working nicely), convert image has problems with bmp files due to widely used nonstandard headers -> needs work
status: initial version done and being used, making 2nd version with better graphics showing the workpiece angle and tool nose
-esp8266 based control for electric door lock, with advanced(js!) and polished(css, anims) web interface for mid-secure RFID administration
status: initial version done and shiny, but overwriting storage of data
-esp8266 based server/client sends UDP packets to LOGIN/ACCESS certain software, secured with handshake, no web interface, config in EEPROM
status: done and being applied on more computers at the time, making esp8266 (Arduino IDE due to multiplatform), Python2 and Autoit3 examples to share

Yay, another nice port to have..
Adafruit lib is better for number of reasons..at least for me 😁
– notes: check esp8266 i2c speed setting in your version of the Adafruit library
if there is no setting in your version, like in my old ones, insert these lines into Adafruit_SSD1306.cpp file, into the fuction which does display init ->
void Adafruit_SSD1306::display(void), pick some line above the „// I2C“ comment, or if u dont know..just leave it or google it..
#ifdef ESP8266 // set speed for ESP devices
Wire.setClock(400000L);
#endif
I am using IRremote Arduino library for some time and have found that it did not compile on STM32F103 board because of different timers. I was looking for some port for STM32F1xx and found only one guy who tried to port it, but it was not working for him..
..tried to fix his code with no success..
..so i forked IRremote Arduino library repo and ported it myself 😎
..fork -> https://github.com/KiLLAAA/Arduino-IRremote
..port thread here -> https://github.com/z3t0/Arduino-IRremote/issues/390
enjoy! 🕶
Friend brought his turntable not working.. It was old Omnitronic DD-2250 poor thing, no reasonable spare parts available, of course..🎉 Problem was broken wire of primary coil in mains transformer..♻🆗🚮
So i replaced the old double secondary transformer with single secondary toroidal one(~10€), plus DC-DC supply with LM2596(<2€).. 🆒
The switching-mode power supply is adjusted @ 15V DC and connected just where the original AC wires were plugged, counting with voltage drops on rectifying diodes and stabilizer LM7812.. Reason was to modify as little as possible to keep things simple..
I was shocked by tremendous 400mA current when i stopped the motor with two fingers..😂😂😂😂😂🤣
Normal spinning took only 80mA, its so greeeeenNNN!!!✅♿ 🤣
(measures were done DC powered @ 29.5V and 15V)
Update: Its still working after half of year..💪🎶🔊
Thank you for your download, we hope you are satisfied with our software.
