Cheap may be one thing, but it can be a a pain to develop on as the same amount of hardware needs to be plugged in as a regular computer. Keyboard, mouse, monitor, power..... that's 4 wires coming off of the Raspberry Pi. Since I try to keep a fairly clean workstation (and don't have extra keyboards/monitors around) I needed another way to use my Raspberry Pi.<div> <br /></div> <div> Enter the <a href="http://www.amazon.com/AT-Laptop-Dock-Motorola-ATRIX/dp/B004M17D62">Motorola Lapdock&nbsp;</a></div> <div> I bought one of these several months ago for my Atrix 4G phone when a clearance website had them for $60. This dock has a male Micro-HDMI port and male Micro-USB port on it to interface to the Atrix phone. I thought this would be a great interface to use with the Raspberry PI; the only pain was finding the right cables/adapters.</div> <div> <br /></div> <div> I knew I had to go from those ports to a full size male HDMI, full size male USB and micro USB for power. Getting the cables needed cheap was a bit of a pain; but eBay and China sellers came through.</div> <div> <br /></div> <div> Now that I had all the adapters I needed it was time to build the cable.</div> <div> <br /></div> <div class="separator" style="clear: both; text-align: center;"> <a href="https://blogger.googleusercontent.com/img/b/R29vZ2xl/AVvXsEjfFefy6C8QsljhkLeFhVWLc5vOczB2iqDU2_wmh1MV9ulVfFZAdelBfXMqTFf-LOcFXbDCECziobkCDP7w5A6tVESjaL2TWJWHNMUthU2i0pyWYdGm15J1tJC5Iycbf8ob9-wgIMbi18iC/s1600/DSC_0305.JPG" imageanchor="1" style="margin-left: 1em; margin-right: 1em;"><img border="0" height="212" src="https://blogger.googleusercontent.com/img/b/R29vZ2xl/AVvXsEjfFefy6C8QsljhkLeFhVWLc5vOczB2iqDU2_wmh1MV9ulVfFZAdelBfXMqTFf-LOcFXbDCECziobkCDP7w5A6tVESjaL2TWJWHNMUthU2i0pyWYdGm15J1tJC5Iycbf8ob9-wgIMbi18iC/s320/DSC_0305.JPG" width="320" /></a></div> <div class="separator" style="clear: both; text-align: center;"> Cables Hacked Apart</div> <div class="separator" style="clear: both; text-align: left;"> <br /></div> <div class="separator" style="clear: both; text-align: left;"> So I took two USB cables I had lying around and cut them apart.
