K10 Relay K10 Hazard Flasher Relay
        Designed to be a drop-in replacement for the electromechanical relay originally used to implement the "hazard" flash function on the 1967-1968 Mercury Cougar and Ford Thunderbird, this is the relay that mounts in the trunk of the car near the sequencer and brake light relays and which appears in the original Ford Motor Company wiring diagrams as "K10."
        Two screw holes provide a mount point to the pre-existing locations in the car. The "bullet" connector mates directly with the ground lead already in the car, and tangs on the reverse side of the board shown here plug directly into the connector where the original relay went.
        This design has no relay contacts to corrode and is entirely solid-state, with no moving parts to wear out. The unit you receive will be slightly different than that shown here, as all "final" products are epoxy encapsulated on the top side to shield all wiring from the elements. The expected life of this unit is at least 3x that of the original electromechanical relay.
"I just received the K10 relay, and it is installed and working wonderfully. Thanks again for designing and making this hard-to-find part and keeping it available to Cougar and T-bird enthusiasts."

-- Phil Parcells, National Cougar Database Registrar        

        Relay K10 may be purchased on-line here through PayPal at a cost of $26.99 plus $4.50 shipping.

Lots of FETs Microstepping Motor Controller
        Work is presently underway on a stepper motor controller with overcurrent and overvoltage protection for use with small CNC milling machines. The final unit will feature low-loss field-effect transistor drive circuitry with full H-bridge outputs for easy microstepping and direction reversal. Inputs to the controller will be as simple as a signal for "step" and another signal for "direction." The driver will get its logic power from the same supply as the motor rails, simplifying wiring eliminating the need for supplemental power supplies. Power supplied to the unit may be anywhere from 5VDC to 28VDC. Current limiting on the motor will be jumper-selectable on the controller board, so you can tailor this controller to meet the needs of many motors. Commutation styles (4-wire bipolar, 5-wire unipolar, 6-wire unipolar, 8-wire, etc.) will also be jumper-selectable, so you can change your motor type as well as current and voltage rating and not have to buy another driver board. In fact, this may be the last such board you ever purchase.
        Check back with us over the upcoming weeks to see how we're progressing.
