Board Update

The LM556 dual timer is going to be discontinued, so I working on an updated circuit using the 555s and am going to integrate it into the PCB.  There will be an updated set of boards that I will be posting shortly.

There are enough different companies manufacturing this chip that it will never die. You can find other 556s on Digikey that will be identical, spec-wise

  Are you sure? yes | no
