Toggling between these programs stops the clock. I would like to modify this thing really bad. Programs 1, 2, and 3 cannot run simultaneous with each other.
If you guys want high res pictures of the PCB, please let me know. There's 4 levels of audio gain 20dB 26dB 30dB 32dB, on the 4 ditgit LED screen I have the volume range from 0 to 40 so, maybe it uses this and some pre leveling before its shot in the TDA chip. volume control can maybe be done by a Arduino using a voltage divider for 3v high/low and then hooking it up to pin 30, 31 on the TDA audio chip. So is it possible to dump and edit this dump of the firmware and flash it again or is it a better idea to just get rid of this microchip and make something with a Arduino ? The audio IC that this thing is using is a class-D TDA7491LP.
Basically the code in the firmware that runs at startup looks at the time and if it's 00:00 it prompts for user input first.
Hardware & my idea: It has a Megawin MPC82L54AT2 8-bit processor, the display is connected with ISP. So when powering up again I first need to set the time again using the volume knob before I can use the damn thing. But the problem I am having now is There's a 4 Digit led display in the front of the speaker and on each power cycle when the mains or batteries are disconnected the time that was set during the startup using the volume knob is lost (it's not saved, its not a RTC, it has no backup battery) I also don't need the time on my speaker (Doh.). We offer a beautiful mechanical clock and simple.
And also Pomodoro Technique reminds you to take a rest for 25 minutes. You can change interval and decide how often it speaks to you. This is useful if you are likely to listen but not to watch the time. I was planning to add the following to the speakers: a BMS, few good 18650 cells, buck converter and a Bluetooth module to it which is really easy. Time Speaker & Alarm Clock provides a talking clock and countdown timer Pomodoro Technique. Hi, So I brought two 360° Logitech speakers for cheap and they sound fine.
