Tempi the Headless pi image

Whenever I start a new RPI project, it takes too long to get SSH/VNC access to the new Pi.

After loading raspbian image to an SD card you’ll need to hook up a screen and keyboard just to connect the newly installed pi to your home or office WiFi. That’s a huge pain.

Solution

I created an image of a newly installed Raspbian, set up the WiFi connection (GB), and Raspi-Configed SSH & VNC to be enabled. That’s it!

How can I use it?

  1. Download Tempi from right here (http://rfed.ws/tempi)
  2. Write image to SD, and boot
  3. Use your smart phone Tethering option to open the following network:
    • Network name: pi
    • Key: 3.141592654
  4. Use a network scanner (e.g. nmap) to find out the Pi’s IP, or use hostname to ssh to your PI (“ssh [email protected]” or “ssh [email protected]”)
  5. The pi password is also set to 3.141592654

Did it save you anytime at all?

ShowerPi mini – DIY Shower voice recorder for only $42

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. You can take it into the shower with you, record your songs and thoughts and receive the recordings immediately in your email.

“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 items. If you are in a hurray and don’t care about the cost – go to the Amazon list where you can expect things to arrive real quick. If you are strap on cash but don’t mind waiting a few weeks for delivery check out the right column – where you can save quite a bit!

ItemFancy optionCheaper option
LiPo Battery (3.7V 1200mAh)  $13 $2
Raspberry Pi 0 W  $23 $10
16 GB class10 microSD card  $10  $8

1 Tactile push button –  $6  $1
4 “Sugru!” 5g packs – $20  $18
A small box (Amazon Dash box is perfect) – –
Optional – M2.5 Nylon Spacer – For fitting $10  $5
Total damage: $126$42 *
*The $42 is assuming you already have wires, can do without the Nylon spacers and looks at half the sugru cost as you only need half of it for the projet. When you buy a product using some of these links you are actually supporting this website.

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.

 

Sugru!

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

If you have any questions, or if you need any help making your own – write me a line below.

What to get?

If you are serious about building your own Shower safe voice recorder, there are a few you things you’ll need in advance. Let’s have a look at a few:

The things (you’ll need):

  1. A Raspberry Pi board. Mine is made with the pi 3 (currently $35.99), but you can get your way with the cheaper (and slower) pi zero (currently $11.99).
  2. micro SD card – Has to be at least 8 GB, class 4 or higher. Like this one (currently $6.85).
  3. A plastic case. Nothing fancy, this one will do.

But, why?

Ah, yes. Reasoning. We all need a good reason don’t we?

ShowerPi is exactly the project for you if you answered “yes” to at least two of the following two questions:

  1. Do you often have “Ah Ha!” moments in the shower, where you find exactly the tune you want to compose (and you are not even a composer), the opening sentence you want to say at the next event, and the start up company idea that’s going to be worth millions of cancer curing hunger busting money making, emm. things. Only to be forgotten the minute you step out of the holy of holies.
  2. You bought a Raspberry Pi (or similar) board, but have no idea what else to with it other than streaming video.

With ShowerPi – You will have a great making project, and you will end up never forgetting a shower thought ever again in your life.

Great!

What is that?

So, what is it?

ShowerPi is a Raspberry Pi based voice recorder you can take to the shower.

Yes, it’s awesome!

Okay. What can it do?

Once on, you can press the single command button on the device. That will trigger a series of events, resulting in the showerPi recording everything you say (or sing) for the next 20 seconds.  After 20 seconds, the showerPi sends the recording to your email for you to enjoy at a drier point of time.

An optional addon is to link your email with a Voice to Text service to add a textual layer to your message where applicable.
