The HUD has some very interesting DIY parts and ideas which you can try out. Maybe a cool wearable. The details on all the parts used are at the end of the post and comments are open for discussion.</p>
<p>The HUD consists of a frame which sits in the same way as you would wear a pair of spectacles. On the right side, a case is attached which holds all the necessary electronics and optics. The HUD receives video signals from the remote which houses the camera receiver. If you are interested, you can buy the full vehicle kit at <a target="_blank" href="http://www.amazon.com/gp/product/B0016A7PGU?ie=UTF8&#038;tag=machinegridco-20&#038;linkCode=as2&#038;camp=1789&#038;creative=390957&#038;creativeASIN=B0016A7PGU">Amazon</a>.</p>
<p>1. First for a few views. Click on the views for a larger image.<br />
 <a href="http://www.machinegrid.com/machinepress/wp-content/uploads/2009/09/atv_360_wild_planet_hud_full.jpg"><img class="alignnone size-thumbnail wp-image-680" title="atv_360_wild_planet_hud_full_view" src="http://www.machinegrid.com/machinepress/wp-content/uploads/2009/09/atv_360_wild_planet_hud_full-150x150.jpg" alt="atv_360_wild_planet_hud_full_view" width="150" height="150" /></a><a href="http://www.machinegrid.com/machinepress/wp-content/uploads/2009/09/atv_360_wild_planet_hud_eye_piece.jpg"><img class="alignnone size-thumbnail wp-image-678" title="atv_360_wild_planet_hud_eye_piece" src="http://www.machinegrid.com/machinepress/wp-content/uploads/2009/02/atv_360_wild_planet_hud_eye_piece-150x150.jpg" alt="atv_360_wild_planet_hud_eye_piece" width="150" height="150" /></a><a href="http://www.machinegrid.com/machinepress/wp-content/uploads/2009/02/atv_360_wild_planet_hud_eye_piece_2.jpg"><img class="alignnone size-thumbnail wp-image-679" title="atv_360_wild_planet_hud_eye_piece_2" src="http://www.machinegrid.com/machinepress/wp-content/uploads/2009/02/atv_360_wild_planet_hud_eye_piece_2-150x150.jpg" alt="atv_360_wild_planet_hud_eye_piece_2" width="150" height="150" /></a></p>
<p>2. So that you know how it looks, I setup two scenes. One with a PostIt note saying &#8220;HI&#8221; and the other a Rubik&#8217;s cube. The LCD is monocohrome however, so the image you will see is not color.</p>
<ul>
<li>The one with the PostIt note<br />
 <a href="http://www.machinegrid.com/machinepress/wp-content/uploads/2009/02/atv_360_wild_planet_hud_hi_post_it_setup.jpg"><img class="alignnone size-thumbnail wp-image-681" title="atv_360_wild_planet_hud_hi_post_it_setup" src="http://www.machinegrid.com/machinepress/wp-content/uploads/2009/02/atv_360_wild_planet_hud_hi_post_it_setup-150x150.jpg" alt="atv_360_wild_planet_hud_hi_post_it_setup" width="150" height="150" /></a><a href="http://www.machinegrid.com/machinepress/wp-content/uploads/2009/02/atv_360_wild_planet_hud_post_it_hi.jpg"><img class="alignnone size-thumbnail wp-image-703" title="atv_360_wild_planet_hud_post_it_hi" src="http://www.machinegrid.com/machinepress/wp-content/uploads/2009/02/atv_360_wild_planet_hud_post_it_hi-150x150.jpg" alt="atv_360_wild_planet_hud_post_it_hi" width="150" height="150" /></a></li>
<li>The one with the Rubiks cube<br />
 <a href="http://www.machinegrid.com/machinepress/wp-content/uploads/2009/02/atv_360_wild_planet_hud_rubiks_cube.jpg"><img class="alignnone size-thumbnail wp-image-709" title="atv_360_wild_planet_hud_rubiks_cube" src="http://www.machinegrid.com/machinepress/wp-content/uploads/2009/02/atv_360_wild_planet_hud_rubiks_cube-150x150.jpg" alt="atv_360_wild_planet_hud_rubiks_cube" width="150" height="150" /></a><a href="http://www.machinegrid.com/machinepress/wp-content/uploads/2009/02/atv_360_wild_planet_hud_rubiks_cube_lens_view.jpg"><img class="alignnone size-thumbnail wp-image-710" title="atv_360_wild_planet_hud_rubiks_cube_lens_view" src="http://www.machinegrid.com/machinepress/wp-content/uploads/2009/02/atv_360_wild_planet_hud_rubiks_cube_lens_view-150x150.jpg" alt="atv_360_wild_planet_hud_rubiks_cube_lens_view" width="150" height="150" /></a></li>
</ul>
<p>3. Opening is not that easy as there are no screws to take apart the top cover which says &#8220;Spy Gear&#8221;. The cover is glued to the case using glue. Taking a clue from <a rel="external" href="http://jakeofalltrades.wordpress.com/2007/09/30/25-head-mounted-display/">Jake</a> to avoid inserting the screwdriver on the side the &#8220;cable does not come out&#8221;, I managed to take it apart. Pry the side where the black cable comes out. The other side has the LCD connector, you might damage it if ou pry that side. It&#8217;s tough at first, but once you get one side, it gets easier.<br />
 <a href="http://www.machinegrid.com/machinepress/wp-content/uploads/2009/02/atv_360_wild_planet_hud_pry_open.jpg"><img class="alignnone size-thumbnail wp-image-704" title="atv_360_wild_planet_hud_pry_open" src="http://www.machinegrid.com/machinepress/wp-content/uploads/2009/02/atv_360_wild_planet_hud_pry_open-150x150.jpg" alt="atv_360_wild_planet_hud_pry_open" width="150" height="150" /></a></p>
<p>4. Once the cover is removed, the PCB becomes visible. The main controller chip is a Kopin <a rel="external" href="http://www.kopin.com/data/File/A300Spec.pdf">KCD-A300-QB</a>. All the other parts are support components for the chip. There is a small potentiometer in one corner which allows you to change camera gain. You can see the display change in brightness when you change it. Try adjusting it, there is no harm in doing so as it can easily be bough back to it&#8217;s previous value by looking at the screen.<br />
 <a href="http://www.machinegrid.com/machinepress/wp-content/uploads/2009/02/atv_360_wild_planet_hud_pcb_1.jpg"><img class="alignnone size-thumbnail wp-image-698" title="atv_360_wild_planet_hud_pcb_1" src="http://www.machinegrid.com/machinepress/wp-content/uploads/2009/02/atv_360_wild_planet_hud_pcb_1-150x150.jpg" alt="atv_360_wild_planet_hud_pcb_1" width="150" height="150" /></a><a href="http://www.machinegrid.com/machinepress/wp-content/uploads/2009/02/atv_360_wild_planet_hud_pcb_2.jpg"><img class="alignnone size-thumbnail wp-image-699" title="atv_360_wild_planet_hud_pcb_2" src="http://www.machinegrid.com/machinepress/wp-content/uploads/2009/02/atv_360_wild_planet_hud_pcb_2-150x150.jpg" alt="atv_360_wild_planet_hud_pcb_2" width="150" height="150" /></a><a href="http://www.machinegrid.com/machinepress/wp-content/uploads/2009/02/atv_360_wild_planet_hud_pcb_3.jpg"><img class="alignnone size-thumbnail wp-image-700" title="atv_360_wild_planet_hud_pcb_3" src="http://www.machinegrid.com/machinepress/wp-content/uploads/2009/02/atv_360_wild_planet_hud_pcb_3-150x150.jpg" alt="atv_360_wild_planet_hud_pcb_3" width="150" height="150" /></a></p>
<p>5. Remove the two screws keeping the PCB in place. Also it&#8217;s time to remove the LCD connector. To remove it, pull the black tab out a bit as in the pic.<br />
 The connector will slip out easily with a slight tug. The connector is pretty rugged. I have already plugged it in/out a few times.<br />
 <a href="http://www.machinegrid.com/machinepress/wp-content/uploads/2009/02/atv_360_wild_planet_hud_lcd_connector.jpg"><img class="alignnone size-thumbnail wp-image-682" title="atv_360_wild_planet_hud_lcd_connector" src="http://www.machinegrid.com/machinepress/wp-content/uploads/2009/02/atv_360_wild_planet_hud_lcd_connector-150x150.jpg" alt="atv_360_wild_planet_hud_lcd_connector" width="150" height="150" /></a><a href="http://www.machinegrid.com/machinepress/wp-content/uploads/2009/02/atv_360_wild_planet_hud_pcb_removed.jpg"><img class="alignnone size-thumbnail wp-image-701" title="atv_360_wild_planet_hud_pcb_removed" src="http://www.machinegrid.com/machinepress/wp-content/uploads/2009/02/atv_360_wild_planet_hud_pcb_removed-150x150.jpg" alt="atv_360_wild_planet_hud_pcb_removed" width="150" height="150" /></a></p>
<p>6.The LCD connector is glued on to the casing. Remember to break it free before going ahead.<br />
 <a href="http://www.machinegrid.com/machinepress/wp-content/uploads/2009/02/atv_360_wild_planet_hud_remove_lcd_glue.jpg"><img class="alignnone size-thumbnail wp-image-706" title="atv_360_wild_planet_hud_remove_lcd_glue" src="http://www.machinegrid.com/machinepress/wp-content/uploads/2009/02/atv_360_wild_planet_hud_remove_lcd_glue-150x150.jpg" alt="atv_360_wild_planet_hud_remove_lcd_glue" width="150" height="150" /></a></p>
<p>6: Four more screws need to be taken out to remove the eyepiece. Use a pair of pliers to do this.<br />
 <a href="http://www.machinegrid.com/machinepress/wp-content/uploads/2009/02/atv_360_wild_planet_hud_pliers_remove_case.jpg"><img class="alignnone size-thumbnail wp-image-702" title="atv_360_wild_planet_hud_pliers_remove_case" src="http://www.machinegrid.com/machinepress/wp-content/uploads/2009/02/atv_360_wild_planet_hud_pliers_remove_case-150x150.jpg" alt="atv_360_wild_planet_hud_pliers_remove_case" width="150" height="150" /></a></p>
<p>7.Before I forget, the PCB has a high output smd LED behind it as below:<br />
 <a href="http://www.machinegrid.com/machinepress/wp-content/uploads/2009/02/atv_360_wild_planet_hud_led_2.jpg"><img class="alignnone size-thumbnail wp-image-687" title="atv_360_wild_planet_hud_led_2" src="http://www.machinegrid.com/machinepress/wp-content/uploads/2009/02/atv_360_wild_planet_hud_led_2-150x150.jpg" alt="atv_360_wild_planet_hud_led_2" width="150" height="150" /></a><a href="http://www.machinegrid.com/machinepress/wp-content/uploads/2009/02/atv_360_wild_planet_hud_led.jpg"><img class="alignnone size-thumbnail wp-image-686" title="atv_360_wild_planet_hud_led" src="http://www.machinegrid.com/machinepress/wp-content/uploads/2009/02/atv_360_wild_planet_hud_led-150x150.jpg" alt="atv_360_wild_planet_hud_led" width="150" height="150" /></a></p>
<p>8. Prying out gives you the lens casing. It&#8217;s pretty well made, with the LCD nicely sitting in it&#8217;s place. It was designed so that the lens was at a fixed distance from the LCD.<br />
 <a href="http://www.machinegrid.com/machinepress/wp-content/uploads/2009/02/atv_360_wild_planet_hud_lens_case_1.jpg"><img class="alignnone size-thumbnail wp-image-689" title="atv_360_wild_planet_hud_lens_case_1" src="http://www.machinegrid.com/machinepress/wp-content/uploads/2009/02/atv_360_wild_planet_hud_lens_case_1-150x150.jpg" alt="atv_360_wild_planet_hud_lens_case_1" width="150" height="150" /></a><a href="http://www.machinegrid.com/machinepress/wp-content/uploads/2009/02/atv_360_wild_planet_hud_lens_case_2.jpg"><img class="alignnone size-thumbnail wp-image-690" title="atv_360_wild_planet_hud_lens_case_2" src="http://www.machinegrid.com/machinepress/wp-content/uploads/2009/02/atv_360_wild_planet_hud_lens_case_2-150x150.jpg" alt="atv_360_wild_planet_hud_lens_case_2" width="150" height="150" /></a><a href="http://www.machinegrid.com/machinepress/wp-content/uploads/2009/02/atv_360_wild_planet_hud_lens_case_3.jpg"><img class="alignnone size-thumbnail wp-image-691" title="atv_360_wild_planet_hud_lens_case_3" src="http://www.machinegrid.com/machinepress/wp-content/uploads/2009/02/atv_360_wild_planet_hud_lens_case_3-150x150.jpg" alt="atv_360_wild_planet_hud_lens_case_3" width="150" height="150" /></a><a href="http://www.machinegrid.com/machinepress/wp-content/uploads/2009/02/atv_360_wild_planet_hud_lens_case_4.jpg"><img class="alignnone size-thumbnail wp-image-692" title="atv_360_wild_planet_hud_lens_case_4" src="http://www.machinegrid.com/machinepress/wp-content/uploads/2009/02/atv_360_wild_planet_hud_lens_case_4-150x150.jpg" alt="atv_360_wild_planet_hud_lens_case_4" width="150" height="150" /></a></p>
<p>9.Going further, pry the top half with a flat head screwdriver. There are four tiny rods which keep it inline. This part should come out easily.<br />
 <a href="http://www.machinegrid.com/machinepress/wp-content/uploads/2009/02/atv_360_wild_planet_hud_remove_lens_cover_1.jpg"><img class="alignnone size-thumbnail wp-image-708" title="atv_360_wild_planet_hud_remove_lens_cover_1" src="http://www.machinegrid.com/machinepress/wp-content/uploads/2009/02/atv_360_wild_planet_hud_remove_lens_cover_1-150x150.jpg" alt="atv_360_wild_planet_hud_remove_lens_cover_1" width="150" height="150" /></a></p>
<p>9.Now for the LCD. The LCD is in a tiny casing which sits in a grooved box. There is a slight amount of glue on one end as in the image. With a flat head screwdriver, as shown, just give a tiny nudge and it should come free.<br />
 <a href="http://www.machinegrid.com/machinepress/wp-content/uploads/2009/02/atv_360_wild_planet_hud_lens.jpg"><img class="alignnone size-thumbnail wp-image-688" title="atv_360_wild_planet_hud_lens" src="http://www.machinegrid.com/machinepress/wp-content/uploads/2009/02/atv_360_wild_planet_hud_lens-150x150.jpg" alt="atv_360_wild_planet_hud_lens" width="150" height="150" /></a><a href="http://www.machinegrid.com/machinepress/wp-content/uploads/2009/02/atv_360_wild_planet_hud_remove_lens_cover.jpg"><img class="alignnone size-thumbnail wp-image-707" title="atv_360_wild_planet_hud_remove_lens_cover" src="http://www.machinegrid.com/machinepress/wp-content/uploads/2009/02/atv_360_wild_planet_hud_remove_lens_cover-150x150.jpg" alt="atv_360_wild_planet_hud_remove_lens_cover" width="150" height="150" /></a><a href="http://www.machinegrid.com/machinepress/wp-content/uploads/2009/02/atv_360_wild_planet_hud_lcd_screen_cover.jpg"><img class="alignnone size-thumbnail wp-image-685" title="atv_360_wild_planet_hud_lcd_screen_cover" src="http://www.machinegrid.com/machinepress/wp-content/uploads/2009/02/atv_360_wild_planet_hud_lcd_screen_cover-150x150.jpg" alt="atv_360_wild_planet_hud_lcd_screen_cover" width="150" height="150" /></a></p>
<p>10. The LCD in all it&#8217;s glory!<br />
 <a href="http://www.machinegrid.com/machinepress/wp-content/uploads/2009/02/atv_360_wild_planet_hud_lcd_screen.jpg"><img class="alignnone size-thumbnail wp-image-683" title="atv_360_wild_planet_hud_lcd_screen" src="http://www.machinegrid.com/machinepress/wp-content/uploads/2009/02/atv_360_wild_planet_hud_lcd_screen-150x150.jpg" alt="atv_360_wild_planet_hud_lcd_screen" width="150" height="150" /></a><a href="http://www.machinegrid.com/machinepress/wp-content/uploads/2009/02/atv_360_wild_planet_hud_lcd_screen_2.jpg"><img class="alignnone size-thumbnail wp-image-684" title="atv_360_wild_planet_hud_lcd_screen_2" src="http://www.machinegrid.com/machinepress/wp-content/uploads/2009/02/atv_360_wild_planet_hud_lcd_screen_2-150x150.jpg" alt="atv_360_wild_planet_hud_lcd_screen_2" width="150" height="150" /></a><br />

<p>11. The following views show the three pieces of the lens casing. Note that the part at the extreme right of each image has a diffused screen to spread light from the SMD LED.<br />

<p>12. This was as far as I could go. The eyepiece is glued together. Trying to take it apart would mean risk in breaking the lens.</p>
<p><strong>Parts and Notes:</strong><br />
 Main controller chip :: Kopin KCD-A300-QB<br />
 Documents  ::  <a rel="external" href="http://www.machinegrid.com/machinepress/wp-content/uploads/2009/02/kopin_kcd-a300-qb_dsiplay_driver.pdf">kopin_kcd-a300-qb_dsiplay_driver</a><br />
 Notes :: This is the driver chip for the 300M LV monochrome display. It is designed to accept a standard monochrome video signal (525 or 625 lines), and convert it for the display.  Unfortunately its a monochrome driver and not a color one.</p>
<p>LCD Display :: Kopin 300MLV CyberDisplay<br />
