Over the years, the 1993 classic Doom has gained an almost meme-like status where it can seemingly run on anything. Everything from printers to smartwatches has been shown off running the now-iconic first level of Doom. Looking to up the bar, [Equalo] set out to run Doom on potatoes. However until we develop full biological computers, he had to settle for running Doom on a device powered by potatoes. (Video, embedded below.)
As we’ve seen with other hacks before, potatoes are a decent power source that just requires potato, zinc, and copper. Some have attempted to make it easier to scale potato power and others have focused on making the individual potatoes more powerful. The biggest obstacle when working with potatoes as a battery is that even though each potato can put out almost a volt, the current is laughably small.
The lack of current is what drove [Equalo] to dramatically scale up the typical potato battery. With a target device of a Raspberry Pi Zero requiring around 100 mA at 4.5V, this means he needed over 700 potato slices. After boiling hundreds of potatoes and with a bit of help from friends and family, the giant potato battery was constructed, and we can’t help but marvel at the sheer scale and audacity. The challenge of scaling up a potato battery is that by the time you’re wiring up the 400th potato, your first potato has already started to corrode.
Next time you’re looking for some inspiration for a monumental task, perhaps watch the tale of [Equalo’s] giant potato battery and remember what can be accomplish ..
