The latest circuit diagram of the AD2496 is shown here. All modifacations I intended and described in the article about the prototype have been implemented. Additionally I introduced two current compensated chokes for higher EMV immunity. Not that I experienced them to be necessary, but I know about the extreme requirements of the relevant regulat

ions. And this design is meant to be professional. from May `06: I also found out that the TOTX141 has to be replaced by a TOTX179P because the TOTX141 is a 3. 3 V type (which does actually not prevent it from working in all my units). Except its operating voltage of 5 V the TOTX179P is fully compatible. Also, the discontinued CS8405A is replaced by the fully compatible CS8406. I rearranged the DIP-switches so that the 4 relevant ones are on the leftmost side. The others are for experimental use and not meant to be populated in an actual device. For my units I used an SG206 case from the (German) company Fischer Elektronik. Front panel, case and board are directly fixed to each other using the element 5. 60. 422 from the (German) company Ettinger, available at BG rklin. You need not necessarily use the case I used. The board can easily be built into other cases. For this case I provided a detailed dimensional drawing, either as a GIF file or as a PDF file. You will see there how the board is fixed within the SG206 and how it can alternatively be fixed directly to other front panels. Of course you may also use four stand-offs, pillars or distance tubes to fix the board on the bottom of your case. The drilling positions can be found in the dimensional drawing, too. The front panel is manufactured by Schaeffer AG (in Europe) and is available in the US from Front Panel Express, LLC, too. You need the design file for the front...
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.....
