Still, I'd like to know the "proper" way to do this. The result was decidedly "meh" but fortunately it won't be particularly visible once the frame in on the wall. I drilled a hole then used a Dremel to cut down to the hole from the edge. This is a testament to my poor woodworking skills. Notice the cut in the frame to allow the power cable out. The above photo shows the Fire held in place, with a USB power cable running from the side and out the bottom of the frame. This means that each corner pieces is slightly different so everything lines up "just so" while avoiding buttons and speakers on the Fire itself. Each piece holds a corner of the fire, pressing it up against the mat, keeping it the correct distance from the sides of the frame, and being kept in place once the frame back is re-attached. Obviously 3D printed mounting pieces are the way to go here. The listening cup is attached to the corner piece D, which places and keeps it in exactly the right spot (the 3D printer files are attached to the project).įrame. This improve the microphone's sensitivity and I can now speak to Alexa at a normal volume. Now, with a sound gap at the back of the frame, I added a little "listening cup" over the microphone to increase the volume of the sound it gathered (imagine cupping you hand over your ear). I added some rubber feet to the corners of the frame to give a little gap between the wall and the frame probably only 2mm, but enough to greatly boost the sound coming out. Plan 2 was to abandon the flush wall design. And while you could speak to Alexa with the frame against the wall, you had to raise you voice which felt unnatural. The microphone is on the left side of the tablet and I wasn't going to drill a hole in the frame there as it would look ugly. It also didn't solve the second problem which was getting sound into the frame the Fire needs to hear what you say - it's Alexa after all. It helped a bit, but really not as much as I'd hoped. This turned out to be remarkably ineffective. The frame is mounted below eye level so the bottom is usually unobserved, and the holes are under the speakers on the tablet. This seemed like a good idea as the holes are essentially hidden. Plan 1 was to drill some holes in the bottom of the frame.
With the box against the wall, the sounds is somewhat muffled. The Fire has two speakers which, once in the frame, are facing down. This introduces the problem of letting the sound out.
For unnecessary aesthetic reasons, I want the frame to be flush with the wall I think it looks neater.
