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 (http://spektakx.com/2012/04/19/a-new-breed-of-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 (http://www.djtechprousa.com/product_detail.asp?display=image&cate_id=63&subcate_id=135&product_id=538) 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 (http://www.flickr.com/photos/riverrats/6953527748/in/set-72157629407019886). 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 (http://hackaday.com/2012/04/18/reading-credit-cards-with-a-tape-head/). 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.
