Homebrew PCBs

Stefan, Myc et al,
The source page from which I found the link to the
Atmel-AVR-controlled oven did have information, and code, for using
various types of Atmel microcontrollers with HD44780 parallel LCDs. 
I'm more familiar with PICs, myself, and that means I've only
toner-transferred the PCBs for the programmers and dumped hex code
into the via the parallel port.

I am working on an Atmel programmer for the AT90S2313, simply because
I bought a bunch of them on eBay to make an LCF meter that reads out
inductance, capacitance and frequency in Morse code, rather than the
ubiquitous similar ones using PICs that display on LCDs. They are
cheap, and I intend to give away the programmed chips and PCBs (the
other components are fairly trivial) at our local low-power ham radio
club meeting soon.

Unfortunately, I'm at the wrong computer, and I don't have the link to
the forum on this one.  It was not avrfreaks.net, though.  I'll find
it and re-post it.  They had a lot of interesting hardware projects on
that forum.

Regards,
Ted
