Introducing – ShowerPi Mini

Again, what is that?

The ShowerPi Mini is a recording device you can take to the shower. It’s based on a Raspberry Pi micro computer.

“Sshhh.. It’s charging.”

Okay, but why?

We live in an amazing time in history where you can make your own things – yet most of us choose to use the things we are given rather than the things we can create. Your phone or even your chair architecture determines your behavior,  and changing them will change your behavior and even your ideas. In my case, my best ideas come to me while taking a shower – and by the time I’m finished I don’t remember my idea of “How to end world hunger with frogs”.

That’s where ShowerPi kicks in!

Okay, okay. But how do I make one?

Glad you asked!

To make your own ShowerPi Mini, you will require the following:

  • ‘Raspberry Pi 0 W’
  • USB mic
  • Rechargeable battery
  • Power Booster
  • Wireless Charging module
  • Some wires
  • A led
  • 1 On Off Torch Push Button Switch
  • 1 Tactile push button
  • Sugru!
  • A small box (Amazon Dash Button is perfect)
  • M2.5 Nylon Spacer

Put it all together

Use the spacer to position the power booster above the pi with enough room for the battery to fit perfectly in between.

I’ll add my soldering choices and rpi code here ASAP. Promise!

Box it


Depending on the box you chose, some adjustments may be required. I needed to cut USB openings for the USB mic and the Micro USB charging module.

Banana is not part of actual device – appears here for measurement proposes only.

After boxing, I used some tape to make sure everything stays exactly in place. You may chose to use something fancier like hot glue or blue tack. After that, I covered the whole thing with one layer of saran tape, for protection.



This is the fun part – coating the device container box with some water resistant sugru.

I ended up only using 4 packets, but you might want to use more.

If you never used sugru before you might want to read up on it – keep your working surface very clean, and use soapy water on the surface and working tools to avoid sugru stickage.

Looking back – one thing I’ll do different next time is using a knife to cut the sugru edges nicely. Another idea is to blend a few colors together to create a jackson pollock like design.

That’s it

Same exact banana as before, for consistency
