Retro Future Unit Converter #ArduinoUnitConverter

This is a retro, future dystopian style fidget toy... but it's actually super useful. I was tired of pulling out my phone to convert inches to millimeters or ounces to grams, so I made this.

You flip the switch, and bam, it's on. No waiting, no annoying ads.

Ever been curious about speed conversions? Like how fast 100 kilometers per hour really is in miles per hour? This gadget's got you. You select 'Length', click the dial to 'Kilometers per hour', switch to 'Miles per hour', and then just twist the dial. And here's the kicker - spin it fast, and the numbers zoom up exponentially. Spoiler: 100 KPH is just about 62 MPH. Not as speedy as it sounds, right?

I crafted the housing in Fusion 360 and 3D printed it with an SLA printer. The dial's a rotary encoder with a click function. The brains? A D1 Mini, juiced up by a battery repurposed from an old disposable vape.

Check out the video to see it in action. Trust me, it's not just another gadget - it's the fidget toy you didn't know you needed.

Vape batteries... i power so many stuff with them, including some of my retro game controllers.

[skram]

Thats awesome. I really want to get into making things like this.

I knew their wouls be a good use for that battery!

[uncannytally]

Absolutely love this. This is really awesome!

Sweet build! I usually just ask Siri which is generally quite fast and she’s in most of the places I need conversions. But she doesn’t look as retrosexy as this! (Shhh don’t tell her I said that!)

I love "useless" things like this more than I should 😅

I think this is a brilliant little retro futurism device and I've started to build my own one. It doesn't need to work better than the internet or a phone app, that's not the point of such things. Adam Savage didn't need to get ruler tattoo on his forearm, with all its flaws, but it's very cool. A big thankyou for the idea and especially for sharing it @HackMakeMod.

I love this one. I could use this on an almost daily basis

[jonathanklinglesmith]

do you have you have a build list and cad files available? this would be super useful for my job.

[par]

You should build a pip boy smart watch and laptop cross!

[prwingman]

@HackMakeMod I built one of your DIY Unit Converters, for some reason when I select (push the button) in the first menu screen it works but pushing the button on the second sub menu does nothing. Do you have an idea what's wrong?

[hotrodAndy]

I love this!!! Fingers crossed you release the code and parts list!

[alejandroruiz]

Cool as hell!!! Congrats.

I wonder when the average American will join the rest of the world. Even medical area, physics and more are already using metric in USA. I wonder if the system is purposely keeping them from learning or the population is too lazy to learn.

[sillyshitt]

Could you talk more about the vape-batteries? They are super useful but how do I prevent overcharging?

[TrigTrig]

any idea where to source a battery for this? I don't have any disposable vapes lol. or maybe a step file so we can resize for our own battery

[james]

USAians will really do anything to keep using the British Empire's units 😂

[mtraven]

are you just using "exponentially" to say, faster...or is it actually exponential? Thatd just be a weird way to program an encoder.

[ajoshdoingthings]

Where's m/s tho
Kinda odd to see fps but mps

[siamesestormtrooper]

Just get the converter+ app. No adds. Does every conceivable unit for more than every measurement you’ll ever need. Not trying to sound like an ad but it is that good

[SaturnsReturn]

I am still baffled by the sheer absurdity of rechargeable batteries in disposable vapes. Makes great power sources tho

If you're going on 100km/h on Autobahn you're slowing down the trucks on the slowlane, nothing a German would flex.
