Non-Functional Circuit Broach




About: My work combines conductive materials and craft techniques to develop new styles of building electronics that emphasize materiality and process. I create working prototypes to demonstrate the kinds of electr...

This is a decorative piece made from functional elements that form a non-functional circuit. The beauty of it lies in its non-functionality. If electricity were to flow, LEDs to blink, motors to vibrate or resistors to resist, then it would just be another circuit board.

Step 1: Materals and Tools

- Perfboard
- Solder
- Circuit board components: resistors, diodes, transistors, capacitors, voltage regulators, potentiometers, headers, LEDs, vibration motors, wire, cable, ribbon cable&
- Safety pin or reuse the back of an old broach

- Soldering iron
- Helping hands
- File
- Cutting knife or small saw
- Wire cutters or nail clippers
- Wire strippers

Step 2: Soldering

Decide on your layout and pattern ahead of time or make it up as you go. Push a few components through the holes for the perfboard and bend their legs slightly to keep them from falling out. Then solder them into place. And repeat this action until you have filled all the holes or are happy with your design.

Here is an Instructable that will show you how to solder >>

Step 3: Fasten Pin

The final step is to attach some kind of fastener to the back of your non-functional broach so that it can be worn. I used the back pins from old pins and they were amazingly easy to solder. First I decided how to place it on the back of the broach, then I held the pin with the helping hands and applied solder to it before soldering it to the solder of the back of the components.

    Your circuit looks so cool!
    However, personally I agree with Comodore. You really should add a 3V coin-cell battery to power the LED. It would look so much cooler!!! It would function as a sort of flashlight as well as a unique work of art!

    Plus, wouldn't you love to see your artwork's beauty at night? I think the components deserve the "spark of electrical life".

    One last thing: I feel your "analogy" is seriously flawed and self-contradictory.
    Other than that, great job!

    pero la concha de su hermana manga de pelotudos no se dan cuenta de ke esta haciendo arte? por dios, ya se sabe ke no sirve para nada, es solo arte, k yankees de mierda

    Really good idea. I agree with you, in that it would just be another circuit board if it was powered. The ultimate must-have for any electronics enthusiast.

    Is it wrong of me to feel sad for the components? I feel like they deserve to feel the spark of electrical life...

    Maybe try thinking about them as retired. Or think about all the components mounted on circuit boards that have ended up in landfill, at least these were mounted with care for this specific purpose:-)

    Very true. I've "retired" a fair share of components in my time, maybe they would be happier as a piece of art instead of being used in a slingshot :P

    Very cool! You put so many components, you could have added a 3V coin-cell battery to power the LED, to look even cooler! All in all a great project! rate:***** +I added it to my Mythbusters group

    you shoulda added a little candle on it and said "this is how my circuit works!"

    This is pretty cool. Awesome and original. Make me wanna make one.
