Do you ever find something completely absurd but you definitely want it?

@ticky I love it, but I'm starting to think you can make anything with a power source and display screen into almost anything else...!

@ticky You don't think that kit could turn a late '90s Casio G-Shock into the same kind of oscilloscope? The chip is external!

@thephunkyjedi the chips were always external! That’s what cartridges are :P

@ticky ooooooook I see what's going on; I saw the chipboard & was like "got it, new chip hack;" didn't register the shape at first!
Still, even if it hangs out awkwardly, adapted to/overwriting the G-Shock OS, I'll bet you could still use something similar to turn a Casio into an oscilloscope, just the same way!

@ticky I don't think portable scopes were all that common around 2000 either (and they still aren't today), which makes that extra neat


Remember, this predates the ubiquity of smartphones and commodity smartphone hardware. In 2000, decent cheap microcontrollers were available but commodity SOCs and touchscreens were not.

The Gameboy was cheap, programmable and easy to obtain and had a screen and controls.

These days, the equivalent would just bluetooth and a phone app. Like this:


Wierdly enough, there's a $100 portable oscilloscope on Amazon as well:

I have no idea if it's any good, but the first couple of reviewers say it's great for the price.

@ticky I saw this video earlier today and was expecting it to be just like this post, but boy was I wrong

@ticky i am obsessed with the Singer Izek, which used a Game Boy Color to automate some of its advanced features

@er1n me too! I should look into how I can get my hands on the schematic/software sometime!

@Efi I mean, hobbyist electronics people in the year 2000?

@Efi please find someone else to start an argument with

@sebastian yeah, I love that! Commodity hardware becoming easier to put together than your own custom stuff is always fascinating

@ticky I'm usually looking out for a slight variation of this phenomenon. If formerly exotic parts are suddenly used in high-volume commodity hardware, they will be sold on cheaply somewhere on the internet eventually.
Like smartphones and MEMS sensors, or various iterations of china gadgets and the ST7735 display I'm currently working with.

@sebastian oh absolutely! I’ve got a spare Kobo which I’m hoping to build some sort of cool software atop; it’s effectively a little passively-cooled, 1Ghz-capable (in bursts, natch) ARM tablet running vanilla Linux with built-in Wi-Fi, a small battery and a great, touch-sensing, 8-shade-of-great e-ink display, in a nice box!

"Commodity hardware becoming easier to put together than your own custom stuff": I'm currently working on my third satellite telemetry receiver based on RTL2832U DVB-T sticks. These things are sooo cheap now that the SDR is almost the cheapest part on my BOM. And there is not much I could improve by making a custom version of those. (maybe a slightly better oscillator, better cooling, maybe a little less power supply noise... but that would be mostly me being picky about things)

@ticky other GB things that exist:
- a fish sonar
- a sewing machine GUI
