Something different

I bought this unit from a local farm store.  It's clearly been on the shelf for a very long time, so I thought it would be good to explore it.  (It cost about £20).

Something different

Comments

Dialog semiconductor have a similar (yet very different) chip for this application - with a nice application note AN-CM-316. Products like this also demonstrate well how broken the patent system is. There's no great leap involved, yet there are so many patents on these "inventions" because using a simple timer circuit to activate something "without human input" is something no-one else "skilled in the art" could possibly have thought of doing, obviously!

Looks like it probably has the same circuit as those automatic air fresheners that has a 15/30/60m timer... Looking forward to checking this video out later :3
