Build an LED flasher from the ground up: Circuit board design, etching, soldering for newbies!
Sunday, February 28, 2010 from 3:00 PM to 8:00 PM (EST)
No electronics experience is necessary for this class! Basic knowledge of conductors and insulators is the important bit, though an understanding of transistors and Ohm's Law would help if you want to grok how the finished circuit works.
Starting around 3pm, we'll take you through the following steps:
- Start with a circuit schematic on paper. (we'll be using a simple LED flasher)
- Turn that into a schematic in electronic design software
- Create a board layout for the circuit
- Print the layout (we'll do this for each student who wants one)
Then each student will build their own circuit, through this process:
- Transfer the printed layout to a piece of copper-clad circuit board material
- Etch the board, chemically removing copper and leaving just the requisite traces
- Clean the etched board, and apply a tin plating which makes soldering easier
- Drill holes for component mounting
- Stuff components into the board, and solder them (no soldering experience necessary)
- Test the finished circuit
This will probably take several hours, hence the early start. By the end of the night, you should have a working LED flasher and a pretty thorough understanding of the design-build process! Ambitious? Yes! Come join us.
Note: A $5 materials fee is required if you want to take your board home. Donations beyond that are happily accepted. i3Detroit is a non-profit workshop funded by dues and donations, and your generosity allows us to offer more classes like this.
When & Where
i3 Detroit is a DIY collective in Ferndale, with tools and resources to facilitate a wide variety of projects. The name stands for "Imagine, Innovate, and Inspire".
Supported by its members but open to guests as well, i3 Detroit's facility hosts workshops and classes as often as possible. Led by volunteer instructors (mostly members), these are usually free, but may require a materials fee for participation.
When there's no class happening (and sometimes when there is!), you'll usually find members in the space, soldering, sewing, welding, sculpting, programming, woodworking, or just hanging out.
Founded in 2009, i3 Detroit has about 70 members and funds its operation mostly through member dues. Donations from students and guests are always appreciated, and have the potential to substantially increase our resources!
