There was not much space inside the keyboard shell, and not enough to fit the scanner's PCB. Under the keyboard, the PCB was held up by a couple of internal supports, and most of that space between the risers was open. I cut away one of the supports, which should not weaken the device significantly, and not in an area subject to much stress.
I wanted the scanner's antenna to be as close to the surface as possible and on the front face where it would be accessible. I had to chisel away some plastic between two of the supports. I only carved enough clearance to seat the antenna against the case.
There was enough magnet wire included with the scanner's antenna to reach around the keyboard PCB. All the keyboard's functions would remain, except for one of the USB ports, and the switch I accidentally ruined on the membrane, but that was due to carelessness, and anyone copying this project should not repeat my mistake.
I put a layer of electrical tape between the scanner's PCB and the Numpad's board to prevent shorting. With my modifications, the case would close up completely, and only one screw was made surplus.
The first time I scanned my RFID implant, I didn't get any feedback. I tried a couple of different tags, including the credit card-sized units, which offer the best read range. To make sure the antenna was scanning, I placed a low-frequency RFID light a the top to prove it was functional.
My inability to scan was a classic case of turning it "off and on again." Once I reset everything, I was able to get scans reliably from all my RFID tags, including the one in my hand. The animation below uses a card because I used my hand implant for computer log-ins, and I don't want that shared.
The rest of the posts for this project have been arranged by date.
