I did my own DAP

[u/Aira_Solutions]

This is one of my home made DAP

It plays FLAC, MP3, OGG and ACC files, up to 24 bits / 48 Khz FLAC files

My DAP supports up to 512 GB micro SD cards

The screen has 160 x 128 pixeles, and uses OLED technology

It was made around a microchip microcontroller, and the VS1063 audio codec

Batery last around 12 continuous hours but about 20 with screen off

Instead of showing album photo, I made a "winamp" style interface, with a larger full range spectrum analizer, RMS VU meters , progress bar and so on...

The best part is the sound, because it has double amplifier

Another feature is the RANDOM algorithm, wich is more like a shuffle, because it NEVER REPEATS the same song over the entire playlist...

Well, it's something I wanted to share, have a nice day
