2.4V power supply- 11.4V output (Vpp).

MCLR pullup

4.2V PIC supply (dc/dc coils).

Diodes 1n4148 / 47u capacitor

Machine language control program / LED matrix clock.

It was rewritten for C language.

It is a microcontroller FLASH writer.
It is connected to Windows PC.
Hex file is loaded, and tranfered by RS232.

I have many clever circuits to show off.
But, I try not to put too much effort into it.

On a forum I only show small circuits.

I don't use assembler anymore. On the picture there is a LED matrix!
It works from 1.2V battery.

On the new picture, a transformerless power supply.
It is advanced level of technology.
