7" element 14 Raspberry Pi touchscreen, untethered

thingiverse

This is a workaround to use the Raspberry 7" touchscreen without having the Pi control mounted on the back, so you can place the touch screen wherever you want. I used a regular 7" pie touchscreen display but no raspberry Pi was mounted on the back. I was able to power it with a standard 5v 2.5a micro usb power supply and connected it using an Adafruit Flex Cable for Raspberry Pi Camera, which is 24" / 610mm long. And it works perfectly. However, my problem now is that I can't find any display case without the raspberry Pi attached to the back. To connect the display to the back of the 3D printer control box, you can use an extension cable. I found a suitable one on Amazon: https://www.amazon.com/dp/B072N7VXPR/ref=asc_df_B072N7VXPR5163563Prusa i3/?tag=hyprod-20&creative=395033&creativeASIN=B072N7VXPR&linkCode=df0&hvadid=216539509836&hvpos=1o1&hvnetw=g&hvrand=13451644732331075226&hvpone=&hvptwo=&hvqmt=&hvdev=c&hvdvcmdl=&hvlocint=&hvlocphy=9002970&hvtargid=pla-405082136327 You can also use a power cord specifically designed for the Raspberry Pi, which you can find on Amazon: https://www.amazon.com/iTrunk-Raspberry-Power-Supply-Extra/dp/B01MA6B6KM/ref=sr_1_2?s=electronics&ie=UTF8&qid=1505096796&sr=1-2-spons&keywords=pi+power+supply&psc=1 Alternatively, you can use an adjustable DC-DC LM 2596 converter, which you can find on eBay: http://www.ebay.com/itm/Adjustable-DC-DC-LM-2596-Converter-Buck-Step-Down-Regulator-Power-Module-LW-SZUS/232372936877?ssPageName=STRK%3AMEBIDX%3AIT&_trksid=p2060353.m2749.l2649
