Subject: Re: [PIC] instructions for modifying El Cheapo for use with ZIF
socket

Redwood Shores, 29 november 2006.

Dear John,

I never tried the original instructions, but I can imagine that they
wouldn't work well with more modern computers. That is the basic problem
with Myke Predko: his ideas are quite useful, but due to bugs in writing,
electronics and software they never come out the way he wanted them to. In a
way it is fun if you are aware of these bugs... Today I was staring again at
his contrast circuit for LCD with a 10 Ohm potmeter, which undoubtedly has
to be a 10 kOhm potmeter. After staring at it long enough, I started
wondering if something like that could be done using a PWM signal and a
capacitor, but I doubt I'll try it.

Greetings,
Maarten Hofman.
