Step 1: Tools and Parts
- Soldering Iron - not essential as the whole project could be done using wire wrapping techniques. I started off with the soldering iron so a lot of the joins were made with the soldering iron.
- Side cutters - for trimming component leads
- Long nose pliers
- Jewelry wire - I raided this from my daughters supply. Looks to be about 1/64" thick and is silver coated which makes it easy to solder
- 10 x 8pin DIP integrated circuits
- 1 x Feature IC - anythng in a bigger package will do to define the center of the bracelet. You could also use the smaller dip packages all the way round for a different style.
- 8 x 100nF decoupling capacitors ( look like blue beads ) (http://www.radioshack.com/product/index.jsp?productId=12401429)
- 4 x 1/4W 10% resistors any value will do - we are using them for cosmetic puposes
- 2 x 1N1418 Diodes (http://www.radioshack.com/product/index.jsp?productId=2062587) - look like glass beads
Step 2: Center Piece
The center piece was placed in the center with the wire running underneath the chip between the legs and the plastic body of the IC. A small dot of solder was used to fix the chip to the wire at each end.
Then the same process was applied to the second piece of wire. You should end up with the center piece fixed to two roughly parallel hoops.
Step 3: Making the Sides
The wire was then bent inward until to match the width of the 8 pin DIP IC. The jewelry wire is run up under the IC so that the wire is between the body and the pins of the IC. The long nose pliers are used to fold the legs over the wire keeping the IC attached to the wire.
Step 4: The Band
The capacitors can be placed into the bracelet by looping the capacitor leads over the jewelry wire and trimming off the excess wire. Initially I soldered the capacitors but after a while, found it easier to keep them in place by wrapping the leads around the jewelry wire.
After all the ICs and capacitors are in place, make sure the pins of the ICs are all soldered to each other to stop the ends from poking into the skin of the wearer.
Step 5: Clasp
Step 6: Finally Done
There are a lot of other ideas for this type of bracelet. For example, using resistors or diodes instead of ICs for more of a techno beading design.
I hope you found this to be a useful guide.
