I cut a vertical notch in the lip, just deep enough to accommodate 2-3 probe wires, with a a wee bit of play so that the wires are not mashed against the drum edge. The air gap is really minimal. I did line the notch with a small bit of foil to protect the probe wires from the metal edge of the drum. The notch works much better then other options. I have done this for both of my drums, and will soon cut notches in all of my cookers... just having a hard time thinking about cutting notches in my kettle though!
Have you read some of the other threads on here re: Arduino based controllers? You may be the first to assemble an Android based one. Of course, the Heatermeter is a superb (and superbly documented) project.
[oh btw - how did you manage to quote multiple posts in your reply? I have been on here a couple of years and have not been able to figure it out!!]
