Finally a fierce man who plays DOOM on the Lego block appears

' DOOM ' released in 1993 is known as the monumental action shooting game FPS (First Person Shooter) that progresses from the first person perspective. In addition, the source code is open to the public, and it is also famous for being ported to all kinds of platforms such as tractor in-vehicle systems , medical ultrasound scanners , and Windows Notepad . A successful person has appeared using an LCD monitor that incorporates such DOOM into the block of the block toy 'Lego'.

I wired the brick up as a very small external monitor, so you can, for instance, play Doom on it.pic.twitter.com/uWK2Uw7Egr

Mr. James Brown living in New Zealand remade Lego as a monitor. Mr. Brown published on Twitter on June 7, 2022 how the Lego block functions as a monitor, attracting the attention of many people.

Very happy about this.pic.twitter.com/1FofmKbqJP

This way it is hidden inside the block.

Mr. Brown said that he uses STM32F030F4P6 (Cortex M0, 16K flash, 4K ram) for the processor and QT1306P82 (0.42 inch OLED) for the monitor.

After that, Mr. Brown made further improvements to the first created block ......

I haven't shared the schematic because it contains an error; you need to rework the boards to route a spare gpio to the screen. This involves drilling a 0.3mm hole through one of the pads, making a break in the ground plane, and soldering a little piece of wire through.pic.twitter.com/hG5MfYq8N4

I created a block that was more opaque and looked more like Lego blue.

The new one is more opaque and a closer match to Lego Blue. I also painted the edges of the screen with black lacquer, which got rid of the glowing surround. It's a very fiddly construction. pic.twitter.com/2AEfSogIfU

In addition, the new block is equipped with a capacitive touch panel, and it is now possible to move the displayed image left and right.

While that one cures, I added the trench run and got capacitive touch working in the studs.pic.twitter.com/dxzEw2uDI9

The resolution of the monitor that Mr. Brown incorporated into the Lego block is 72 x 40 pixels, and the number of colors is 1 bpp .
