There are other chips or programs that do blanking and fading in from the side which is a cool effect. Like the signs at the ballpark. I don`t think this one does that particular trick but I intend to find out! The clock goes into slot machine mode every n minutes to avoid the dreaded cathode poisoning (of your cat). The second one was two 1-2W

Velleman mini amplifiers with improvised mics and small loudspeakers as earphones, driven with a 9V battery. It was loud enough to work in 100km/h, not much more but we were using earplugs. It is not very quiet to drive fast with a mc. randy909, I think when you use a quality preamp you begin to realize how crappy most of the consumer stuff really is. Think about it, if you buy a mackie it has 16 pres in it and eqs and busses and sends etc for the price of 1 quality pre. That should say everything right there. I`ve used mackies and similar for years so I have nothing against them but getting a quality stereo pair is essential in my opinion. I would say that using a consumer pre is actually degrading the signal. A good preamp can make an sm57 sound phenomenal. I`m sure they make a world of difference with microphones, but I was wondering about your experiences with running synths through them. Are they the secret to that big sound, or do they just add a little top-end sweetness Maybe the difference (compared to your mixer) is more obvious when you push them a little bit, or a lot. Or maybe line-level is line-level and there difference is very slight I was trying to get the Russian driver chip to work but couldn`t unravel the mystery today. I thought all I had to do was ground or supply a small amount of voltage to each of the four input pins on the IC. The combination of lo/hi on these pins determines which cathode of 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.....
