rubber door insulation was then cut and placed around the display to provide some protection. \u00a0The powerbank was held down with Velcro, and connected to the Pi and display using short micro USB cables. \u00a0Finally, a short SMA cable was used so that aerials can be connected externally.<\/p>\n<p><a href=\"http:\/\/www.daveakerman.com\/wp-content\/uploads\/2015\/12\/P1110304.jpg\"><img
