Fun with 1.1GHz Potato chips

Fun with 1.1GHz Potato chips



I built a ring oscillator using a 1.125GHz 74 series logic inverter IC from Potato Semiconductor. It was fun.

    I am confused how do they can they update the design -_-

    God, now I want to build one of those 70's era diy cpu kits out of this ttl logic.

    It woukd have been interesting if you told us how to thworitically make that iammer. Would be so educative. Because its simply from a cheap 74ic. Pls condider

    To be honest, I was kind of expecting a chip powered by a potato, a la Portal 2.

    Far as I can tell here, I believe those harmonics you are seeing would be down to the actual signal being generated being a square wave. This is pretty clear by every second multiple of the fundamental frequency having a higher spike in amplitude which summed make a square wave. I'm not sure why there are smaller spikes between, but they won't have much effect given a small reduction in dB is a huge reduction in signal in real terms. I would guess the low bandwidth of the oscilloscope in comparison to the 2nd harmonic is probably why the scope is outputting a sine rather than the square wave the signal analysis suggests is present.

    So essentially what you've made there is the world's most unexpectedly complicated, digitally readable thermistor?

    Your blowing skills works as frequency changer. šŸ˜€

    Heat sink it…. Then you can cool, 'the hot potato chip'….

    Careful how you solder them, unless you're okay with lead in your Potato chips.

    I understood about nothing you said there, but Iā€™m really interested! Where would you recommend someone start learning about this stuff? Where did you start out?

    That would be a good way to upgrade potato GLaDOS (Portal 2)

    If someone steals one of these chips, does it become a hot potato?
