UM is a low-cost, low-power CMOS LSI designed for use in alarm and toy applications. Since the integrated circuit includes oscillator and selector circuits. The UM is a low-cost, low power CMOS LSI designed for use in toy those indicated in the operational sections of this specification is not implied and.

We were looking at a simple and more efficient way of doing the same. We made a luggage security alarm with the help of musical tones IC which is powered with 1. The moment the lock is broken, the IC generates an alarm either a police siren, fire engine siren, machine gun sound or an ambulance alarm thus notifying the owner about the theft of his luggage, hence alarming the owner about the theft. Since the sound is weak, an amplifier is necessary to get loud sound. A single NPN transistor will amplify the sound. However, someone may cut the chain and steal our luggage. Here, is a simple circuit to alarm you when somebody tries to cut the chain.

Download the UM66 datasheet. Etch the board, remove the toner and drill. The PCB is ready. Printing PCBs Use a transparency of good quality.

To save time, effort and expenses it's a good idea to combine multiple images to try and fill the entire 8.

Remember that these must be printed as mirror images of the final PCB in order to be correct after transferring them to the copper board. Placing the PCB mirror image face down on the copper E. Transferring the Image To proceed you will need a cutout of a single PCB image from the glossy paper, a very clean copper board and a clothes iron.

Place the PCB mirror image face down on the copper, ensuring it is correctly positioned. You can use a few pieces of tape to secure the glossy paper to the board but I find that, if you are careful when you begin to iron, the paper sticks and stays in place on its own. Iron the entire area of paper, pressing firmly and staying long enough to ensure the toner melts a bit and binds to the copper. Carefully remove the paper. If certain areas seem particularly difficult to peel off, you can try soaking a bit more.

Somewhat hotter etchant will react faster than a cold solution but we like the ease and control that using room temperature etchant affords us. Regularly stir the solution, every couple of minutes, to ensure the board is in contact with fresh etchant. After a while, you will be able to see that the reaction has begun. The etchant solution will get filled with dark colored particles and the copper will begin to disappear.

Removing the PCB from the solution for a few seconds will reveal freshly etched spots. The process seems to accelerate in the final stages; this is only an impression but it can surprise you and lead to over-etching.

Leaving the board in the solution too long will cause the etchant to eat at your signal traces from below, potentially causing breaks in your traces. Etching the Board Fig. Final PCB G. Finishing the PCB Drill holes as appropriate, place your components and solder. Ferric Chloride, the etchant When creating a PCB using a chemical etchant, you want to protect certain areas of copper from the chemical reaction to form the pads and signal lines and let the ferric chloride remove all the metal that remains exposed.

The next step consists in removing unwanted copper from the board. You can use the classic, ferric chloride or other chemical solutions. You won't need a ton of etchant for a regular sized PCB. Start with a bit, enough to cover the board.
