Build a Simple Inexpensive Ballistic Chronograph by Ron Newton
The Ballistic Chronograph Kit contains everything you need to build a professional quality projectile speed measuring device. The kit uses exclusively through-hole parts to simplify assembly. The remote display unit allows you to position the measuring system in difficult or hard-to-reach locations, such as on the floor in the middle of your Hot Wheels™ car jump ramp or on the kitchen table next to your Nerf™ gun target. You can also place it in a safe position on a gun range for real bullet speed tests.
The kit includes all the parts listed here:
*Battery and tripod not included
NOTE: This kit contains custom hand-fabricated components that are created specially for each order, so please allow additional time for preparation and delivery.
