No. This uses specialized data format for this movie.

@@neocat100 so if i want to put a video in this, which format should i use or how to put video in??

The algorithm is based on relatively simple depth-first search. It simply select the movable action one after another, and if cards become unmovable anymore, or infinite loop, it backtracks and scans another move. It is written in Ruby script language, check the source: github.com/NeoCat/exapunks_solitaire_solver/blob/master/solver.rb

@@neocat_steam Wow! Thank you for such a quick reply! I've got this bit now. I'm still wondering how should a human player approach this puzzle, is it solvable without brute-force?

@@Vechyaslaugh Actually this puzzle is easy enough that the same approach is able for mortals too, if the app just provides 'Undo'. (There might be some cleverer way to rank each move, but I didn't have to devise it since it is easy and fast enough with back tracking in most cases.)

sure

@@neocat100 thank you

Abdul Samad The shift registers of the panel regards 3.3V as HIGH enough. (Panel is powered 5V) Library needs to be bit modified to support 192x32. (change width, and slow down refresh rate)

@@neocat100 so i will start connecting panel directly to esp32 (accroding to library pinout) and then try to run 64x32 panel then i will move to 128x32 and then finally to 192x32

no you need a power supply to drive the LED panel - up to 4A worst case with all LED's on max brightness

AdaFruit say there 32x64 LED panel needs 5V regulated power input @ ~4A (with all LEDs on) i don't the the ESP can supply that

no these panels are like 4amps

@@yeogav what is bundle? what is exec? and send.rb?

Most boards take USB input @ 5v. So, yes, the ESP can run them directly off of USB, as long as the power doesn't exceed USB power levels. Keep usage under about 2A, and you'll be fine. Exceed that, and the board will go into low power and reset. You can avoid this slightly if you put a capacitor inline with power, but if you draw too much current its not going to help. I have mine running fine off of usb for *months* at a time. See pixelated.cn for some examples.

AlhimikHQ Yes! The library is here: github.com/NeoCat/ESP32-P3RGB64x32MatrixPanel/tree/128x32 Pls check 128x32 branch.

@@neocat100 good work, can by use 4 matrix?? or 8 matrix 2x4 ??

AlhimikHQ More panels to drive mean slower update rate. You will see it flickers with more panels.

@@neocat100 and how to fix the code to connect at least 4 panels? because I already bought 4 panels, I don’t know how to stick them can take raspberry then?

AlhimikHQ You can easily change the library by modifying rows to 256 and reduce timer frequency (timerWrite(timer, 120, true); etc. ). In addition, drawPixel can be changed to edit alignment.

Jalak Lenteng Will this app work for USA WWV? I tried it and it would not sync to any of my atomic 60KHz clocks. The clocks did see the signal but nothing happened.
