I have an old blood pressure meter I was able to hack and receive data from a "tx" pad on the PCB. The LCD screen on this meter has come detached. It looks like the paper thin ribbon cable had been glued in place and the glue dried out after all these years (nearly 20). I'm not sure how, but the electrical connection itself appears to have been made with some sort of conducting glue.

While I considered purchasing a similar meter and hoped to find another accommodating "tx" pad, I decided to take the less risky approach and purchase a Bluetooth enabled meter. Hopefully the Bluetooth interface won't be too hard to hack.

I've been spending a lot of time writing code for my CNC router project. The CNC router will make it much easier to make the pieces I need to continue building this robot.
