PIC power supply basics

Nice toys, Archangel.

I was also inspired by the JDM post. Problem is, I tried to get smart and substituted the zener for a 7805 (have a bunch of those).
Maybe it's better to try the wheel round first before testing if square works!
On that JDM post again. How in the world does he get such a nice PCB using the iron-on process. I was doing that years ago and even started using magazine paper way back as my own idea(now suggested all over).
The color fliers dished out at traffic intersections also work well.

Most so called RS232 serial ports don't put out the presumed 12 Volt supply nowadays.
A programmer that requires it, won't work with a 5 Volt serial port.
A 12 Volt supply can be produced with a buck converter the way that
a max 232 provides a real RS232 serial port for a pic with a 5 Volt supply.
