The Response: The BlinkyHat Project
Start with a camp hat, add some lights, some batteries, and a little tiny computer.
Follow the steps to get from a pile of components to a finished project.
Look out for the ATtiny85v code and the PDF of how to do the wiring.
With the support of the think|haus hackerspace in Hamilton, Ontario and specifically Adina Bogert-O'Brien and Trevyn Watson.
Step 1: Materials Required
- pre-assembled circuit board & battery pack
- 3 AAA batteries
- laser cut battery pack carrier / name plate
- 4 white LEDs
- 4 blue LEDs
- CR2032 3V battery
- 8 straight pins
- sewing needle (that will fit through the holes in the perf board)
- 25' plain poly-cotton thread
- 25' conductive thread
- 2 1-1/2" sections double stick foam tape
Step 2: Prototype #1
Most of the wiring is just moving things around so that it all fits on the one board.
Coin cells are awesome for doing stuff like this midi-breadboard.
Step 3: LEDs
We'll be doing both a mechanical and an electrical attachment.
What did I tell you about coin cells!
Using pliers, bend the negative leg (the shorter one) into a square-ish shape and the positive leg (longer) into a roundish shape.
Step 4: Laying Out the LEDs
Step 5: Attaching the LEDs
It's important that the parts are all held on strongly before we get to the electrical connections.
Step 6: Attaching the Electronics
Step 7: Grounding!
Finish up by bringing the ground wire up the inside of the hat and then through to the ground pin on the controller.
Step 8: One LED at a Time...
When you get done, test to make sure it works by putting batteries in!
Step 9: Now That's a Nice Hat!
Step 10: Well... Not Quite
I'm not sure how to implement this exactly.
