Showing off new hardware..

[von Ryan]

OK, now it's the time when I leave this thread... To much maths for my brain... I HATE maths...

[HangFire]

It doesn't seem too complicated at first glance, if you've even taken high school level physics then you should at least have a gist of whats going on there.

What has maths got to do with breast implants?

[von Ryan]

I am at High School, but I haven't studied that part of physics... Just the dynamics and heat parts...

actually the matrix is confusing me too, to some degree that is. I have no clue what everything does, except that it has to do with some power circuits or something. But then again, i don't care about hardware , i am all software

Ahhhh... those schematics reminds me of the good times
Personally I'd have used the RS232 UART with a MAX232 chip to convert back and forth to TTL levels, because with that setup you'll monopolize your printer port *edit* while you're at it why not put a cheap microcontroller for the serial, LED and LCD logic such as a 80C552 ? You can reprogram it countless times, it's an EEPROM. And it can be programmed in C, even

@Leagle: you silly

[Leagle]

Well you can't fail to call it hardware, but I'd hate to be the one doing the installation.

Still learning all that stuff, but that schematic makes sense! Even the reason for pull-down (or was it pull-up? it's a little blurry on my screen) resistors! (debouncing). Makes me want to look at ADC internals again (never fully understood how they work).
