Runs no problems on the same power source with the LX, the switch rate is slow so interference is not an issue. The 555 and transistor (see what I said about substitutes in the linked thread) will be available from DSE or jaycar, the nichrome wire you might have to substitute as I found that gauge hard to come by in OZ. I didn't build the dewstrap as I bought one from scopestuff with some other bits. Laurie reports that old electric blankets are a good source for the nichrome wire, so if you can find an old blanket that might be the go. Silicon tubing is available as fuel tubing from most hobby suppliers.
