Custom DIY Qi Charger Project

thingiverse

Here's a project born out of unique circumstances. I've been surprised by how many people in the 3D community face similar predicaments, so I'll post this to possibly inspire you. It all started when I bought a new case for my smartphone. Not just any case, but an Extra Battery case with Qi charging capabilities for my iPhone 6 (see Item One in pictures below). Previously, I purchased a magnetic phone mount for my car. This product is really slick (see item two). However, the metal disk for the magnetic holder interferes with the Qi charging capabilities. After some trial and error, I was able to find a location low enough on the charger that allowed it to charge in my stand charger (see item three). Unfortunately, the charger next to my bed just wasn't strong enough to get around the displaced magnetic field. So I decided to make my own solution. The first step involved creating a new coil that aligns with the height and shape of the above magnetic disk, encompassing the internal coils. To achieve this, I purchased a DIY charger kit from Amazon for $8.99. Next, I created the alignment plate, unsoldered and unwound the coil, and wrapped it onto the plate using contact cement to keep it in place. Then, I re-soldered the coil to the circuit board and used adhesive to mount the circuit board to the back of the plate. The box was designed to accept the plate as its floor, which was also glued into place with a bead of silicon to pin it down and ensure the edges of the vinyl weren't rough. From there, I mounted the USB circuit board to the back and printed the feet. These have a cup design that allows me to put a daub of silicone rubber in each one and mash it down with a wet finger, creating non-skid feet. It would be much easier to buy stick-on feet from the hardware store, but I was too lazy to make the trip.
