For Jake... According to the Magnetic Gun Club an AA battery has a few times more power than a 9mm bullet. But, as they point out, The trick is how to convert the chemical energy into mechanical kinetic energy. Instead of a railgun I was thinking it might be more fun to retrofit an old hot wheels track to be powered by magnetic coils.



Back in March I had an entry on Cat Door Scan which uses image recognition to lock/unlock the cat door depending on who or what is trying to get in. Wondering how things are going I found that the cat door was busier than usual on Christmas day. Guess the cats thought they ought to contribute their own gifts.
