A complicated clock featuring 3 ATmega8A and a ATmega328p

I bought a USBasp SPI Programmer, seems it's way better than using an Arduino Nano (Faster, and more reliable)

Just find out that my DIY linear regulator has a large voltage difference between with or without a load. Seems there's a huge room for improvement.

My own joule thief is running for 72 hours, It's now flashing

Couldn't get a AT89S52 work with Arduino Nano (as ISP), the crystal oscillator generated no signal, XTAL1 gives a strange DC voltage.
