Make your own Custom Electronic Widgets, like my Arduino LED Day/Night Widget.

Picture of Make your own Custom Electronic Widgets, like my Arduino LED Day/Night Widget.
        This is just a brief run down on how easy it has become to make your own circuits complete with your own PCB's.  Have you ever wanted to make something custom that suits your needs?

Of course you have!!




       For me it really started when I built my first day/night light. I used a light dependant resistor to determine if it was dark and if it was to then turn on an LED light.

I then went on to add a movement sensor. From there I built a multi channel lighting controller. With very small thin low voltage wires running all over the place, hot glued in spots to the walls and floors. I can’t tell you how nice it is to have automated lighting. It seems like such a simple thing to go over and turn on a light switch, but believe me after having an automated system, If I go somewhere else to another house or hotel I realize how luxurious and satisfying it is not to have to turn the switches on and off in order as I move from room to room.

       So what started out as a simple test of coding and sensors and logic, has seen me refine the design iteration by iteration. Not really in terms of capability but more in the way the parts come together and the way it is used. In terms of the hardware I have gone from breadboard, to prototyping board and soldered parts, to a fully custom printed circuit board (PCB). In the way of usability I have gone from very messy blobs of electronics laying on the floor, to an encased multi channel box, but with wires everywhere, then to a single board per light solution, with onboard adjustable dials.

Thanks for the feedback diy_bloke. I can't really stress enough that the PCB's are so cheap that you can afford to give it a go.
Only $15 delivered for 10 of them, double sided, solder masked and silk screened both sides.
I hope that once people try the tutorial they will realise how simple and cheap it has become. Now you can purchase your boards like any other cheap components.

Interesting, maybe slightly an open door for the somewhat advanced DIY-er, but it may certainly be a good stimulator for the beginners to tacjkle PCB making/ordering.

Yet I think I would choose to make at least a test PCB and etch that yourself. How often have I made a PCB, was convinced it was 'a ok' only to find out while soldering that I had made a stupid mistake in it :-)

I liked your suggestion (at least I think I read that) to make some extra islands. I have often been saved by those if I had a slightly bigger component or decided to add something.

Thanks for the address of Shapeways. That was really usefull for me.
