The story is like this. Around January 2020, I saw on the Zhuanmou Zhuan platform that hxd was selling a 6-bit Bluetooth glow clock for 200 RMB, with 51 as the main control. I thought it was a good deal. I bought it in two clicks, but hxd told me that he had gone back to his hometown for vacation, and that was it. By the time I got it, it was already June, so touching!

Then the problem came. This hxd directly used someone else's first version of the solution.

First, I don’t like the layout. It’s long and the tubes are asymmetrical up and down.

The second is the old chip used by Bluetooth, which only supports Android 4

Anyway, I feel unhappy, so I plan to half-copy, half-draw, and redo it, and the plan is basically finalized. The drawings on the two boards are similar, but there are things that haven’t been decided yet, and it just so happened that the hub was doing a solicitation this time, so, you know!

Updated on August 1, 2020! The board has been welded, the neon bulb has been tested, and the boost debugging of the control board is almost done, and the triode and 595 ING are waiting to be purchased!
