I followed the directions, but the double-sided sticky pad provided is near useless. The circuit board comes off of the pad every time I pull the USB cable out of the plug. I tried a 3M command strip with the same results. What's the best way to mount it in the tin? Wishing I had some Sugru, but that wouldn't get here before Christmas, at which time I was hoping to have given the thing to my dad...
The circuit gets hot, but I'm not sure the circuit should get that hot. Does your Boost seem to be working properly otherwise? Are you getting the correct voltage readings according to the tutorial? What kind of batteries are you using? You might want to check it over for a short-circuit.
A hardware store might have some sort of hi-temperature tape. A thick blob of clear silicone adhesive might work, but check the temperature ratings on it. Really, anything that's non-conductive and thick enough to keep the circuit from touching the tin.
My tape seperated itself, so I used some double sided tape I had lying around. It only holds as long as I haven't had the device in use. After a short while, it gets loose due to the heat. I got optimum readings concerning voltage when I measured it as per the tutorial when putting it together.
I can get my thermometer (thermocouple) this weekend and measure how hot the surface of the IC gets...

An easy test is the 'sizzle' test. If you lick your finger and touch it to the chip and it sizzles, it is too hot. If not, it is fine. These chips do run hot when charging a high current load like a phone.
