Remember the old 90s joke that Doom can run on anything? The classic science-fiction horror game has been ported to many, many platforms and devices over the years – including some bizarre choices like ATM machines and toasters.
Here’s one that capture’s the game’s horror roots, and is pretty awesome! George Merlocco created the Painsaw, a chainsaw built to run Doom.
He explains the project:
“It’s a hack, a modded Echo Junior Chainsaw toy which actually had pretty neat working internals. While I wish I could have kept them, there was a small motor which drove the rubberized chain ‘blade’, and a speaker with (albeit, heavy aliased) sound effects from a gasoline chainsaw that revved up the longer you held the trigger down. The trigger even had a working safety, and I was able to keep that, but it’s not wired up to a button any longer.”
“The system powers up via a 4400mAh Li-Ion battery upon the flick of the main rocker switch. This effectively enables the Adafruit PowerBoost 1000 Charger which feeds that power to the Raspberry Pi Zero. Connected to the Pi Zero’s 40-pin GPIOheader, is the Adafruit PiTFT 2.2” HAT which is the cutest 320×240 2.2” TFT LCDperfect for a scaled-down, bloody chainsaw.”
“Within the rest of the gutted chainsaw body there is a 4-port USB Hub which is connected to a USB OTG cable that plugs into the Pi Zero’s Micro USB host port. The ports on the hub are consumed by a USB nano-receiver for the wireless mouse and keyboard, the HDE XBOX360 USB wireless receiver (allows you to use a wireless X360 gamepad), and a USB soundcard which provides full system sound output to a tiny 1” driver that came with the chainsaw (for the original SFX).”
“The X360 USB receiver is within the body of the chainsaw, but there is a hole near the handle which gives access to the pairing button, so you can use any X360 controller. The Adafruit PowerBoost 1000 Charger is also positioned to allow for charging the battery via its Micro USB port, located the the bottom of the painsaw.”
Even better is the video demo. It’s made in with a grainy VHS-like resolution and is timestamped with the date of Dec. 10, 1993–the day that the Doom was released.
