Introduction: Raspberry Pi Pad! Capacitive Touch Screen Tablet!

A brief guide on making your very own touchscreen pi pad!
Element14 capacitive touch screen £60
Apple ipad mini battery £10
Lithium battery charger and 5v usb 2a driver board £5
Raspberry pi 2 £35
Soldering iron and skills
Ply wood and saw skills £5
Dremel and cutting discs
Wood glue, hot glue gun

Step 1: Uses Element14 7 Inch Capacitive Touch Screen. Dremel Away the Screw Tabs and Buy a Longer DSI Cable.

Step 2: Remove Tall Components From Raspberry Pi Pcb. Ethernet and Dual Stack Usb Ports.

I had a USB power and charger PCB with two single height connectors... so i robbed them from the pcb and they fitted nicely to the PI... (Shown in picture 2 - lower picture)

Step 3: Get Your Hands on an Ipad Mini Battery, Hollow Out Some Ply Wood With a Chisel.

Step 4: Arrange Components, With Tape and Hot Glue, Glue Ipad Mini Battery in Place. Solder Wifi Direct to Pi Pcb!

Step 5: Saw Some Ply Wood and Make a Booking! Install Software Per Instructions on Element14 Website. Fit Low Profile Usb Connectors.

Step 6: Bandaging, Badaboom... One Beautiful Pi Pad!

Does anyone know if this is compatible with raspberry pi 1 model B?

This is weird, but cool!! I was just looking through instructables for ideas on how to finish off the edging of my raspberry pi tablet, and i found your tablet, which looks almost exactly like mine!!! :-D And we finished ours about the same time too. :-D

So I am running Ubuntu MATE, (trying to install Kodi, but it is not supported yet), i downloaded a really great on screen keyboard which pops up whenever a text field is sensed. I have a bluetooth miniature keyboard for when i need to use it. The case i made is from Balsa wood as it was a bit of a rough draft. I shall fill in a parts list on a separate listing and what i did so as not to hijack your thread :-) But how exciting that we built such similar tablets! Nice to see that your woodworking and battery choice was much better than mine! :-D

Hello Howard, Here is another alternative to your USB porting dilemma: I found these USB & microphone/ speaker cable assemblies on eBay for $10 USD.

http://www.ebay.com/itm/281241943640?_trksid=p2057...

This would allow you to remove the USB sockets from the PI, and relocate them elsewhere on your case where ever it might better fit. Hope this helps.

Cheers.

Hey HowardT4,

You have inspired me to do an instructable too. I shall link to your instructable as i think you have some much better features.

The battery life is about 12 hours, but as the sound output from the Pi2 on vlc has loads of interference, i have not pushed the performance for that long.

I didnt remove anything from the pi, i still use the various features (rj45 etc), so wanted to keep it complete. I did mount it in a reverse position though and the thickness is the same as the batteries, so it works out well. :-)

I am still looking for a way of trimming the edge next to the screen that looks pretty. I was thinking of using the plastic from the sheath of a wire/cable but i shall have a play and see what 2.0 brings :-)

Hopefully I shall post the instructable today so you can see more pics and a parts list etc.

Thank you for such a nice response. :-D

Dude!! That is awesome!! - I'm impressed... did you unsolder the tall stuff to make it thinner? - Eitherway, looks great... are you going to put up an instructable?
