Seyfarth Synopsis: The Ninth Circuit holds that the ADA does not require a 36 inch length of clear sales counter space when the entire counter provided for all customers is at an accessible height.

I got some Geiger tubes a few days ago and built a very simple Geiger counter circuit that is powered entirely through the microphone jack (microphone connection provides a little power for things ...

The Geiger-Muller (GM) tube allows a user to measure different types of radiation, including alpha, beta, x, and gamma particles. A GM tube consists of one anode and one cathode enclosed in a ...

Max. Range: 9,950 meters with two digits slip it in pants’ pocket For walking and jogging This circuit measures the distance covered during a walk. Hardware is located in a small box slipped in pants’ ...

In frequency counters, the gating time allotted for counting is often too short to resolve low frequencies. A phase-locked loop could be used to multiply the input frequency. But in some cases, the ...

This is an oldie, but oh, man is this ever good. It’s a Nixie clock made without a microcontroller. In fact, there aren’t any logic chips in this circuit, either. As far as we can tell, the logic in ...

The main principle of this circuit is to increment the values on seven segment displays by pressing the button. Generally, one can see the digital displays, which display the score when buttons are ...
