  Hmmm, the hardest part would be coming up with the impact resistant electronics. This, in fact is a hard enough job that there still isn't an electronic "smart gun" on the market despite over 10 years of r&d. And i suspect that gun companies have dumped a lot more money into this sort of project tha you have at hand.
  
  The next problem would be mounting the electronics to the hammer without changing the balance and feel of it too much.
  
  One potential solution to both problems might be to make the device seperate from the hammer... instead something you mount close to where you are driving the nail, perhaps including pliers to hold the nail for the first strike.
  
  The electronics on the offhand device would not need to be as rugged, and as it is being held to the surface you are driving the nail into it should pick up the sound and produce the cancellation pulse as quickly.
  
  That should greatly reduce your R&D costs and possibly make a more cost effective final product.
  
  If you insist on hammer mounted, i suggest someth…moreing with universal mounting that can be easily applied or removed, thus easily replaceable should your robust electronics nt have enough shock resistance... but for this i suggest making it and selling it as cheaply as possible, else few will bother replacing the first one they break.
