I am planning on making a good hot plate controller
That was kinda my thought - reflow oven options. I suppose that needs a nicer LCD for the profile display. Hotplate is probably better, I think most people prefer those, I thought even big places like SparkFun used to use them. To start I just want to try my own iron controller though :)
Could the pencil type selection be config option? For thermistor ground JP4 with a transistor and source from a 5V PWM signal? Maybe directly from PIC pin?
Is the design partial to a 18B20? They seem expensive when I price them (besides samples), and 1-wire is a pain. Microchip has cheap analog thermometers that I have in my junk box (To-92 as well).
The 24F is super overkill :) It has a great number of accessories for mischievous fun though. Lots of PWMs for LCD contrast and backlight (auto) adjustment :) For a one-off personal project, it is in the junk box too.
