Alright, so, today I wanna chat about this fun little project I tinkered with: the hamburger phone. Yeah, you heard right, a phone shaped like a hamburger. Don’t ask me why, I just thought it’d be a laugh.

First things first, I needed a plan. I’m not exactly an engineer, so I started by gutting an old, broken landline phone. Found one at a thrift store for like, two bucks. Score!
Next up, the burger itself. I considered a lot of things – cardboard, foam, even trying to 3D print something. But then I saw this cheapo squishy stress ball set online, shaped like burger parts. Perfect! Ordered that bad boy.
Okay, so once the squishy parts arrived, it was time to get messy. I carefully sliced them open, trying not to completely destroy them. I needed space inside for the phone’s guts, ya know? The speaker went into the top “bun,” the microphone in the bottom, and the keypad…well, that was trickier.
I ended up cutting a hole in the side of the “lettuce” piece (best fit, honestly) and mounting the keypad there. Not the most elegant solution, but hey, it worked! Lots of hot glue involved, lemme tell ya.
Wiring was a pain. I’m no electrician, so I basically just copied how the original phone was wired. There was a lot of “try this, nope, try that” involved. But eventually, I got the speaker and mic connected to the squishy burger.
The real challenge was getting everything to fit inside and still be…well, phone-shaped. The squishy parts weren’t exactly designed for electronics, so it was a tight squeeze. I ended up using some foam padding to keep everything in place and prevent short circuits.
- Cut the squishy burger pieces
- Wired the speaker & mic
- Mounted the keypad
- Stuffed everything inside
After hours of fiddling, gluing, and probably inhaling too many hot glue fumes, I finally had a working hamburger phone. It looked ridiculous, felt even more ridiculous in my hand, but damn, it worked!
The final touch? I added a little ketchup squirt bottle as a prop next to the phone. Purely for comedic effect, of course.

It’s not pretty, and it’s definitely not going to win any design awards, but it’s a hamburger phone. And I made it. That’s all that matters, right?
