<p dir="ltr"><font size ="2"><font size ="2">Considerations:</font></font></p>
<p dir="ltr"><font size ="2"><font size ="2">a) we have to tweak the template so it will be a better fit for more phones (like iphones) and find a mechanism to secure the phone so it doesn't slide</font></font></p>
<p dir="ltr"><font size ="2"><font size ="2">b) adjust the template to accommodate people who wear eyeglasses</font></font></p>
<p dir="ltr"><font size ="2"><font size ="2">c) the magnet locations do not work for all phones so i consider magnets to be optional. dodo case now sells a kit with capacitive touch buttons</font></font><br><br><br></p>
<p dir="ltr"><font size ="2"><font size ="2">As for software, I think Google cardboard is compatible with other stereoscopic software, so this can be used on Android and iPhone. </font></font><br><br></p>

HAK is not just about tinkering with electronics and hardware. It's about making things and experimenting. </font></font></p>
<p dir="ltr"><font><font>We roasted coffee and cacao beans. We used the Hot Top coffee roaster. 8 oz of cacao beans yield 6.4 oz of roasted cacao nibs, which is a pretty good yield. </font></font></p>
<p dir="ltr"><font><font> Cacao nibs are sold at health food stores for about $13 per pound. A pound of cacao beans is about $5 from Grand Central Market in downtown Los Angeles. There are various applications for cacao nibs aside from the obvious one of making chocolate. </font></font></p>
<p dir="ltr"><font><font>We decided to try making cocoa tea, which required grinding the nibs to a coarse powder. This required three passes with a burr grinder. When we got to a fine grind, things started clogging up due to moisture and oils in the nibs. We discussed the difficulty of grinding cacao finely enough to make a smooth chocolate. You can't get it done with a coffee grinder. Maybe a flour mill. Or a rock tumbler using stainless steel balls? </font></font></p>
<p dir="ltr"><font><font>We tried to brew it like coffee using both a drip filter and a vacuum pot. we also tried putting it in a tea bag and steeping it. we also tried making a hot chocolate mix by adding two spoonfuls of ground cocoa to two spoonfuls of sugar to about 4 oz of hot water and a dash of cream. It was pretty good in all its incarnation, though you ended up chewing on the grounds with the last method. </font></font></p>
<p dir="ltr"><font><font>Other things people worked on were circuit boards, arduinos, and web application. I learned how to use my Singer sewing machine. We broke down a cardboard box that used to hold paper and used it to laser cut two sets of Google Cardboard vr goggles. The template requires a minimum cardboard size of 9 in X 22 in. It needs some adjusting to account for eyeglasses and phone cases. It would be nice if we could programmatically change the </font></font><u><font><font>cardboard</font></font></u><font><font> template depending on head and phone measurements. It may also need a little adjustment if the material is of a different thickness. It worked okay for our cardboard, which had a thickness of 0.13in. </font></font></p>
<p dir="ltr"><font><font>Since we were playing with cardboard, we thought it might be cool to figure out other things we could laser cut and fold. Or maybe we could laser cut a jigsaw puzzle. </font></font><br clear="none"></p>
