![]() ![]() Set the time and it will wake you up as you want.ġ.If something goes wrong your watch may be damaged.Ģ.Only that person can wake up who has wear this machine.ģ.Electric shock is not good for health so never try to increase the voltage range.Ĥ.Never use the charger/ adapter or current from any source. .jp: 2nd Generation Electric Alarm Clock, Shock Clock, Alarm Clock, Electric Alarm Clock, Wristband, Absolute Wake Up Alarm Clock (Rectangular). There is no doubt that you will miss the work you have to do in the morning. ![]() You have to set the time and when the alarm time will come then you will get the mild shock that will wake you up daily in the morning and then you can be able to do whatever work you want to do. It is very easy and every one of you does it. This is not so complicated that you cannot so it. You must be paired with your Shock Clock to be able to set an alarm. Connect the transistor as shown in the diagram.ħ.The two terminals of the transformer which is left black till now will be connected to the two different wires then to the two different metal sheet or metal ring or we can say conducting metals.ĩ.When the alarm will ring you will get the mild electric shock.ġ0.Total electrical circuit is shown in circuit diagram tab. We then recommend that you re-pair and re-set your alarm. If your Shock Clock has been fully drained of battery make sure to charge it. Make sure that your Shock Clock is fully charged (for at least 3 hours) and paired correctly. You can now be able to see the spring like structure that willĤ.Connect first wire in the positive terminal of the battery and the second wire in the spring.ĥ.Take the transistor which should be NPN. The Shock Clock will not automatically go off if you set an alarm using your phone’s default alarm app. To allow for greater current and faster operation, most bipolar transistors used today are NPN because electron mobility is higher than hole mobility.ġ.Take Transformer in your hand which converts 220v to 12v or 12v to 220v.Ģ.Identify the wire by passing the 12V current in the first pair wire if the voltage in the second wire is 0.65v then change the wire then you can find out that it is coming 2230v.ģ.Take the watch and de assemble it. Most of the current is carried by electrons moving from emitter to collector as minority carriers in the P-type base region. In this “on” state, current flows between the collector and emitter of the transistor. That is, when there is a positive potential difference measured from the emitter of an NPN transistor to its base (i.e., when the base is high relative to the emitter) as well as positive potential difference measured from the base to the collector, the transistor becomes active. A small current entering the base is amplified to produce a large collector and emitter current. NPN is one of the two types of bipolar transistors, consisting of a layer of P-doped semiconductor (the “base”) between two N-doped layers. A classic analog alarm clock has an extra hand or inset dial that is used to specify the time at which to activate the alarm. To stop the sound or light, a button or handle on the clock is pressed but most clocks automatically stop the alarm if left unattended long enough. ![]() Some use sound, some use light, and some use sensors to identify when a person is in a light stage of sleep, in order to avoid waking someone when they’re deeply asleep, which causes tiredness, even if the person has had adequate sleep. The primary use of these clocks is to awaken people from their night’s sleep or short naps they are sometimes used for other reminders as well. Transformers are essential for the transmission, distribution, and utilization of electrical energy.Īn alarm clock is a clock that is designed to wake a person at a specific time. A wide range of transformer designs are used in electronic and electric power applications. Transformers range in size from thumbnail-sized used in microphones to units weighing hundreds of tons interconnecting the power grid. This varying magnetic flux induces a varying electromotive force (emf) or voltage in the secondary winding. A varying current in the primary winding creates a varying magnetic flux in the transformer’s core and thus a varying magnetic flux through the secondary winding. Material required: Transformer, NPN transistor, connecting wire, alarm watch, 12v battery.Ī transformer is a static electrical device that transfers energy by inductive coupling between its winding circuits. Aim : To make an alarm battery which will awake you at the correct given time. ![]()
