On my way flying from LGA to SF I lost my iPhone.
I have since become an Android user.
I had an unfinished project making a controller for my iPhone via the charger input, so I needed to make one for my droid instead.
Researching, I came across this post on Hack a Day, which links to a schematic.
Rich Kappmeier’s original post.
Unfortunately the resistance values shown in the schematic don’t register as a 3-button controller by my phone. It’s an AT&T Avail, it seems to just support a single button control.
I may need to try swapping more resistance values, but in the mean time was happy with a one button control.
Would love to have one of these!
Taking a TRRS plug, I wired it up.
I then thought it would be grand to have a contact switch, using your two fingers. The timing for the clicks to be read by your droid can be tricky and I didn’t want pesky mechanisms to get in my way.
There is a Brother PE770 embroidery machine at the SF TechShop. I took a class and hopped on to make a switch, embroidering a design of nylon thread and conductive thread to make my two contacts.
