completion of the project.....

Finally, after completing the design of the project, as well as the radiator coil..the project can begin to be tested to people. Eventually, the project was working..once I switch on the device, the led blinks and where the radiator coil is applied, the led light would be dimmer. That shows the device can be used. But at the same time, now it is time to test my circuit on the subject. This is to prove that the device can really induce sleep...

This is the complete circuit after designing, soldering and winding coil is being done. It is important to me to test the circuit in order to make sure that this device actually can work out.

radiator coil...core of the electronic sleep inducer

After working on the circuit for few weeks, I decided to continue my project on working out on my radiator coil. This coil is the most important element in the project. Because, without that..I could not run the project, in other words..i couldn't induce sleep, how am I going to test my project, hehehehe...so, to create the radiator coil, what I did was by getting a 40 mm steel bolt with a 6mm diameter..and winding it with a 0.2mm enameled wire for about 600 turns. It takes time to wind the wire due to the wire is very thin and easy to break. So high concentration needed in order to wind it perfectly. 

This is one of the technique used to wind the wires on the steel bolt.

redo the circuit...=((

eventually, after designing the circuit...it didn't work out well due to wrong connection...it was a disaster when the circuit i designed did not worked properly...i didn't know what to do, whether to troubleshoot the circuit or redo again. It was difficult to identify where was the mistake, and time was running fast. Then, I figure out on to do the circuit again and that time, I had no choice but to redo the circuit but this time...I am using the strip board to complete my project. Well, it is a lot difficult rather than etching, due to designing a project by using the strip board needs high concentration to connect the jumper wires for each components. I took time to construct the circuit. These are the pictures that uses the strip board. 

This is the picture roughly on the design on the circuit. It is a bit complicated, but that also teaches me on how to solder it. It also requires good soldering to make sure that the component doesn't come out.
