Digital Step-Km Counter -  Pedometer has a range of 9.950 meters with2-digits. Slip it in pants pocket for walking and jogging (added 02/05)
Electronic distance meter Based on Motorola 68HC908QY4 -  (electronic circuit added 4/05)
IR distance ranger covers 1 to 20 cm -  11-Apr-02 Issue of EDN  Commercially available IR distance rangers typically handle a 3- to 30-in. detection distance. Many times, it is necessary to determine smaller distances. The circuit in Figure 1 is useful for measuring small distances to reflective surfaces. Its measurement range is from less than 1 cm to approximately 20 cm for a flat, white surface.... [Design Idea by Paul Florian, McKinney, TX]
Micro-Laser range finder -  (schematic / circuit added 2/07)
Pedometer -  Pedometer has a range of 9.950 meters with2-digits. Slip it in pants pocket for walking and jogging (added 02/05)
