Building new interfaces with an iPad

There’s a word – synchronicity – to describe two disparate events that occur together in a meaningful way. We see this a lot in the Hackaday tip line; two people send in somewhat similar hacks solving similar problems in similar ways nearly simultaneously. Here’s two builds by [Bryce] and [spektakx] that hit our inbox within minutes of each other that both implement existing interfaces with iPads.

iPad turntable controller

[spektakx] sent in an iPad powered DJ MIDI controller he built as a prototype to test out the size, orientation and layout for an upcoming build. The turntable controllers are simple USB affairs made to jog and scratch records digitally. Although [spektakx] admits it’s a little unfinished, it’s still just a prototype. Also, he can use a Windows 7 tablet laptop for ‘more suited’ hardware. Check out [spektakx]’ video demo after the break.

an iPad cash register

[Hacktheory] found [Bryce]’s Flickr photolog of a DIY ‘Square’ cash register. The electronics part of this build is practically non-existent; it’s just an iPad with a credit card readers that plugs into the headphone jack. Yes, we just saw these ‘Square’ credit card readers this last week. The fabrication portion of this build is incredible – [Bryce] has a few wonderful pieces of walnut there, and did an exceptional job with the wood work. It’s probably not well suited to high-volume retail, but we couldn’t think of a better cash register for a boutique shop.

  1. (iPad turntable controller)

    Nice project and with a nice finish!

    The video itself could be cut down to 2 minutes if explained without redundancy :)

    1. Hi, yea, It’s difficult it is in certain situations(skype meetings, conf calls, etc.) to get your point without doing that; so the re-re-hash is my default style of explaining. Sorry it was a bit dull :)

  2. The app running in the top half of the image is called TouchOSC, which you can make your own control boards up with and link to almost any MIDI controller. Personally I can’t wait until the next version of FL Studio comes out which will offer full support for it.

  3. That flicker photo log of a diy cash register has no diy in it. Its an advertisement. Knowing woodworkers I’m sure its atleast five grand for a days work.

    1. Its pretty cool in person. Looks really nice.
      It might not be the most beautiful thing in the world but its the first one ive seen that makes a “swipe” area that protects the square dongle.

      In my opinion it makes it look a lot less tacky because its covering up the dongle and keeps it from getting snapped off on accident ;)
