This particular model speaks in a pleasant female voice at the touch of a button, and if you need to be reminded of something during the day, it has an alarm function to, for example, wake you up from a nap at a prescribed time (via a live rooster alarm serenade. see buyer comments below). There`s also an every-hour-on-the hour time announcement, which I find annoying

- got me into a heap of `trouble` once (see story way below) - but it`s a function some people like and will find useful. You have your choice, using another side button, of turning this feature on or off. There are many obvious possible uses. You`re in a dark movie theater, and want to know the time. Even in a dimly lit bar or niteclub, with all the noise, it can still be heard quite clearly. Or on a street with heavy ambient traffic noise. The elderly, or vision-impaired individuals, find them extremely practical. Also, many have been purchased by campers and backpackers. this is quite a good application, actually. Most people just want an easy to use, gadget type watch (women seem to be very impressed by them even more than most guys, not because of the gadget concept, but because of its practical value). The watch arrived just as Karen, my helper and I, were getting ready to leave for, IN, where Institute branch is. It was time for my 6-week checkup following the first PDT Laser surgery treatment on my left eye. I had Karen read the instructions for setting the time and, working under two strong magnifiers, I followed the instructions. When we arrived at the clinic, a nurse took me back to the last room in the building. I sat in the dark room, waiting my turn. Suddenly the rooster started crowing and I almost jumped out of the chair. It was so unexpected and loud that Karen heard it clear out in the waiting room. (The...
This project fits more for custom made battery casing that can have more space to hide things inside. This switch with few alterations can be used for any other project as well but is designed based on e-bike needs! This project use a clever functionality of....
The circuit described here uses ultrasonic oscillations and operates based on the propagation velocity of these oscillations in the air. Thus, we can easily determine the distance of two points if the time within which the wave travels this distance is....
Sometimes the precious metals are hidden too deep and are not detected except with complicated devices. In many cases, however, small pieces of precious metal buried near the surface can be detected by relatively simple means. Everyone is very attractive to....
Many times for various reasons we forget or can not water the plants that we have in our homes. And many humidity sensors units just notify us with a beeping sound or with a flashing light, that the pot needs watering. But what if we are away from home? This....
The principle behind a metal detector is really very simple. Proof of this is the circuit that follows, in which it proves that the construction of a metal detector can be done in the minute, with few components that we find very easily everywhere. With the....
The sub-harmonic bass generator is a sound producing unit for guitars. The sound it produces looks very much like that of the bass guitar. The octave generator is sometimes quite unusual since it does not produce any of the usual ways of coloring the sound,....
In the past the sounding (sea bottom measurement) was done with the "bullet", that is, with a heavy lead object that the seamen plucked into the sea hung from a calibrated rope. As soon as the "bullet" reached the bottom, the depth appeared directly from the....
This Amplifier was designed to have the following specifications: Distortion less than 0.1% at full power of 100W even at 20KHz. Power has to be attributed to an extended bandwidth. The output transistors must be protected against short circuits. The power....
A series of LEDs serve to alert the gardener when plants need water. Using two conventional digital integrated LEDs and a series of LEDs, we make a very useful device for gardening. The device detects the amount of water in the pot and alerts the grower.....
