Can anyone explain which part of this board inflates its price to 280€?

(It's an extension board for my heatpump to control power limits.)

Did not expect that much ash. But that relentless little 2 did its job without complaining.

Want to guess what that job is?

Huh? Is it because of the unusual resolution? An aspect ratio of 10:9 is perfectly normal, isn't it?

So, my TV and an obscure Android App are currently the only two things I know to be incompatible with the GB Interceptor.

(Ok, and iPhones, but they just don't support external webcams, so I could as well list chocolate bars as incompatible.)

(Also, I find your lack of space after the period disturbing.)

(That's all.)

If anyone wants to play with the JPEG compression demo (the discrete cosine transform) from my talk: I have uploaded it to my site at

I have been asked about the lag of the GB Interceptor. While it is designed primarily for streaming and recording, I find it acceptable for playing, but I am a rather casual player...

1/2

Various combinations of Game Boys running the demo game of Tetris while comparing it to the video from the GB Interceptor on the screen of an iPad. Looking at a moment when a dropping row reappears, a lag of 60ms becomes apparent.

Someone just pointed out that iPadOS supports external webcams since version 17. And sure enough, the GB Interceptor works nicely on an iPad Pro.

Video of a hands holding a Game Boy Color and playing Tennis on it. The game cartridge is not directly plugged into the Game Boy, but through the GB Interceptor adapter, which in turn is connected to an iPad Pro that shows the exact scene from the Game Boy Color.

Some might say that creating a custom Game Boy ROM with the logo just for a title slide is overkill. But those probably have no idea what the is...

I will give a Game Boy talk at the !

My topic "Reconstructing game footage from a Game Boy's memory bus" has been accepted.

Can't wait to geek out with the perfect audience for this :) Anyone there who wants to meet?

Time to reveal my wooden Game Boy, which I CNCed out of walnut wood. How do you like it?

Photo of the CNC machining process. A block of wood on the wooden bed of a CNC router is already showing the recognizable design of the backside of a Game Boy. A spinning fine end mill is drilling into a part of the battery compartment. The wood is noticably brighter than the finished Game Boy as it has not yet been oiled.
Photo of the dark brown wooden Game Boy with white buttons and white screen bezel ist standing on a white surface with a dark blurred backdrop. It shows the title screen of Tetris. To the left and right are wooden Game Boy cartridges. The left one has the same color as the Game Boy and has a carved label reading "Pokemon Walnut version". The other one is made of brighter wood and reads "Pokemon Oak version".
Detail shot of the power switch at the top of the wooden Game Boy. The shot also shows the white screen bezel and the detailed decorative lines that are part of the recognizable design of the original Game Boy.

@JetSm00th A what now? Let me google that...

@JetSm00th Never seen (or smelled) one of those. But after the oil has hardened, the Game Boy does not smell particularly strongly unless you stick your nose to it.

A little miscalculation while working on some details for the video on my wood Game Boy mod. I am surprised that most of those 300µm parts actually remained to hold the logo.

Oiled and equipped with a main board from an original Game Boy. It fits almost perfectly along with the (non-original) power switch and battery contacts. Now I need some spare time for the top half. 1/2

Inner side of the back half of a Game Boy case made from walnut wood. Many cutouts, bumps, drill holes and other structures are visible which serve to hold circuit boards, screws or controls. At this point it is only the wood piece without any electronics.

In particular one can see how the main board fits with controls sticking out of the cutouts on the side, battery contacts going through gaps towards the battery compartment on the back and a breakout board for the headphone jack screwed into the bottom end.

Minor issues: Took away a layer too much at the top, which I will have to fix with the top half. That mistake also affect the screw near the power button, but I will probably glue the case anyway as I don't entirely trust the screws in the pre-drilled holes. 2/2

Most excellent maker Blinry decided no longer to let his lack of a sense of direction deter him from adventures, and built a Pico-powered belt to guide him north.

@phranck @Raspberry_Pi Checked the comments to see if someone had already made that joke, so I don't have to :)

I just made a wooden Game Boy Cartridge :)

Sequence of close-ups of the process to create a wooden Game boy cartridge with a CNC router. It starts with a 30cm by 7 cm plank of walnut wood and carves away parts until two halves of a Game Boy cartridge shell have been created. It is assembled with a circuit board and inserted into a blue Game Boy Pocket to verify it works.

Chamfering is so satisfying.

(Until the machine did a second much deeper pass because I had loaded the code for the profile cut...)

Closeup of a rough round cut in a piece of wood. A large V-shaped bit passes over it and leaves a smooth bevel.

@kkarhan It's a Genmitsu PROVerXL 4030 V2 with an end mill from Sorotec specific for foam cutting (although normal bits should also work ok).
After searching for ages for a decent affordable Linux compatible Software I ended up using Blender CAM. Not exactly a recommendation if not already familiar with Blender.

it's a pity we don't have 3D printers that can make fully functional computers. like, a 3D printer that can put down new shapes in silicon.

then you could write a programming language that doesn't multitask for new threads: it instead creates a new CPU and runs the thread there. True parallelism!

DiConX,
@DiConX@mastodon.social avatar

@foone Well, I could make a programming language that orders a new CPU for each thread. No?

I got myself a CNC router 😀
...and just playing with EVA foam is already a lot of fun!
