Counter for Wilder Winder

A Printed Counter for the Wilder Winder: A Rubber-Powered Indoor Plane Counter The electronics in this counter are based on a Trumeter 7000AS, a high-speed counter that can keep up with the output shaft's speed, providing true turns on the rubber. This counter offers both up and down counting capabilities, as well as a reset function. I've made one prototype, so it may require some fiddling and adjustment to get working properly. NEW V2: This updated version replaces the spring-loaded mechanical brake with a magnetic brake, offering more reliable braking and easier installation. This build provides an output-shaft counter for the Wilder Winder. It uses a reed switch and magnet as input to a high-speed counter, fitting the stock output shaft fitting. Additionally, it features a brake/lock system with 1-turn positioning. To print this design, follow these steps: * Print the wheel flat face down * Print the lever on its side, forming an "L" shape; some printers may require support in the magnet hole, but try without first * Place the case top face (where the counter mounts) down and add supports in the hinge area to ensure proper rotation Assembly Steps: 1. Install the wheel into the case, ensuring it's aligned with the unthreaded side of the collar. 2. Feed the rubber hook collar into the hub of the wheel, carefully aligning the opening in the wheel hub with the opening in the collar. 3. Remove the upper right screw from the Wilder Winder and replace it with a magnetic screwdriver to help guide the shaft hole onto the output shaft without losing alignment. 4. Rotate the wheel until the cutout aligns with the mounting screw hole, then insert the screw and snug it down. 5. Place the second rare earth magnet on the outside of the face of the round part of the case near the hole for the brake and rotate the wheel until it grabs the magnet. 6. Mark the exposed side of the magnet, then glue it into the locking lever using Shoe Goo or CA. 7. Mount the locking lever in the hinge area using two small screws, ensuring it rotates freely and the magnet land goes into the case hole cleanly. Testing Operation: * Wind the rubber to ensure the counter agrees with the mechanical counter * Switch the toggle to count downward and touch the button to reset * When stopping, press the brake button in gently and unwind slightly until it catches; it should do so in less than 1/4 turn of the output shaft. * The brake will release with slight forward motion on the crank; be sure you have a good grip on the rubber as it may release when removing the rubber.
