Liquid Cooled Overclocked Arduino Part 1

The overclocked, liquid cooled Arduino running a blink sketch, and submerged in chilled nonconductive coolant. This is a normal 16 MHz Arduino that is overclocked to run twice as fast. The project details are at antipastohw.blogspot.org and www.liquidware.com

Heat isn't the reason for it to be set at 16 or 20 MHz. Running a crystal with such long wires is just asking for trouble . are you even sure that it runs at 32 MHz and it's just not spurious ?

@almouloudi

you have to remove the cristal and buy a 32Mhz one and replace it. :)

Atmel AVR processors don't max out at 20MHz because of heat; they max out at 20MHz because of internal clock signal and data propagation delays. You can probably run them faster than 20MHz (like the poster did), but at some point, the processor components will simply not be able to complete an operation within one clock cycle.

You dont need to cool it @32mhz. thats even IN the specs. get something like 75 mhz :)

[FSK1138]

because you can

[linagee]

What was the temperature of the chip before cooling it? If it wasn't even warm to the touch, there's no reason for cooling it.

[gdorwin26]

you dont need it in coolant. it isnt going to get that hot.

[keoni29]

Or replace the processor.... This thing is huge.

[almouloudi]

Why you need 32 Mhz on Arduino but you also didn't specify how to overclock it anyway .

i did notice it slowed down slightly when you took it out of the coolant, i can understand the concept behind it but why not use something not as "gonna be wiping that off for years" big and use something like an attiny or something?
