Liquid flow
Liquid flows are "natural" transmission components. It can trigger a wash-out detector.

Minecart track
Minecart tracks are pathways that minecarts can run along.

Greenstone wire
A "greenstone" wire uses cactus mechanics that cause them to break when there's a solid block adjacent to them.

Variations: Cactus height can be increased to increase the "circuit" delay. Also, torches can be used, but they seem not to work in Pocket Edition.

TNT wire
TNT wire uses primed TNT to ignite other TNT, to form a chain reaction. TNT can destroy blocks, so it can be used to trigger a block destruction detector. However, this wire is laggy, expensive, has a random delay, non-renewable (in Survival) and can destroy blocks around it, unless encased in blast-resistant blocks.

Variations: This wire can be made one-way only by using advantage of primed TNT obeying gravity:

Sign chain
When a sign is broken, attached signs are broken too. This chain can be used as an instant circuit.
