You can Make Relay Based Motorcycle Alarm Circuit Diagrams . You can use them to protect your motorcycle - but they have many more applications. If you use relays with 6-volt coils - they'll protect your "Classic Bike". Both alarms are very small. The completed boards occupy about half a cubic-inch - 8 cc. The standby current is zero - so they won't drain your battery. Relay Based Motorcycle Alarm Circuit Diagram 1 uses a SPCO/SPDT relay - but you really only need to use a SPST relay. If you are going to use the veroboard layout provided - you'll need to use the style of relay specified. But you can build the alarm using whatever style of relay you have available. Relay Based Motorcycle Alarm Circuit Diagram 1 Any number of normally-open switches may be used. Fit the mercury switches so that they close when the steering is moved or when the bike is lifted off its side-stand or pushed forward off its centre-stand. Use micro-switches to protect removable panels an...

In this article we will discuss how can you make PCBs using Eagle Layout Editor 5.6 Freeware (PCB design). First of all Open Eagle , under Projects right click and then left click to New Project . Give a name to the new Project , for example ‘ example’ and then click Enter . Right click the example , you created, and select New and then board. We will design a simple led chaser using PIC16F84a micro-controller. Add the component needed for this circuit by clicking on ‘ADD’ icon from tool panel in left. After arranging the components we get the figure like this: You can also assign the name to the component by selecting ‘name’ icon and then chose the component which is to be named. Now select the ‘wire’ icon, and the color for wire (normally I chose red). After tracing select the ‘polygon’ icon and draw a polygon (across the whole circuit), after doing this click on ‘Ratsnest’ and you will get this: Now give the name to the polygon (for example Vcc,Vss et...

Often we do not have the opportunity or the money to keep our hobby, sometimes we lack tools, but always there is a knack for everything, is what we see here in this article was originally published at indestructible. He teaches you how to make your own breadboard using scrap old computers, in fact it uses sockets IDE cable. The breadboard makes life easier for those who like to create electronic circuits, and can only plug components without using solder.

The article discusses a simple IR remote control circuit which is configured for operating a DC motor in response to the switching made from a standard IR remote handset such as a TV remote or a DVD remote. The connected motor can be moved either ways and also can be made to halt. The circuit may be understood with the following explanations: As can be seen in the given circuit diagram, the sensor is any standard three pin IR sensor module which would typically respond to any TV IR remote handset. When an IR (infra red) beam is focused at the sensor, the pin which is designated as the output becomes logic low. This situation persists as long as the beam remains focused at it. The transistor T1 which is a PNP responds to this logic low signal and conducts switching the attached relay RL1. The contacts instantly connect the instantaneous positive potential at the collector of the transistor to pin#14 of the IC1 which is wired as a flip flop circuit. Assuming the initial ...
