Hi,

More shameless promotion. We have two new kits coming out this week. One is the Switch Kit. It takes a spst switch of your choosing and produces debounced gate, trigger, and toggle outputs. It has status LEDs for the gate and toggle output and has right-angle 3.5mm jacks for direct mounting to a panel.

The second is the A-440 Generator. It does pretty much as the name implies: generates a crystal-controlled sine wave. It uses a walking-ring counter and weighted resistors to produce a pseudo-sine, then filters out the remaining harmonics. Straight out the CMOS Cookbook.
