Binary Code Name Bracelet Craft
Translate your name into binary code and make a bracelet with beads — one color for 0, another for 1. Wearable computer science that looks cool too.
What You'll Need
- 1Beads in 2 colors (plus spacer beads)
- 2String, cord, or elastic for bracelet
- 3ASCII binary chart (printed or on screen)
- 4Paper and pencil for planning
What You'll Need
Beads in 2 contrasting colors (plus spacer beads)
String, cord, or elastic for the bracelet
An ASCII binary reference chart (printed or on screen)
Paper and pencil for planning
How to Play
Look up the binary code for each letter in your name (A=01000001, B=01000010, etc.).
Write out the binary for each letter on paper.
Choose bead colors: white = 0, black = 1 (or any two contrasting colors).
String beads following the binary for the first letter.
Add a spacer bead between letters.
Continue through the full name.
Tie off the bracelet. "Your name in computer language!"
The Science Behind It
Every piece of data a computer processes — text, images, music — is ultimately stored as sequences of 0s and 1s (binary). Each letter has a binary code assigned by the ASCII standard. By encoding their name, your child is doing exactly what a computer does when you type on a keyboard: converting human-readable text into machine-readable binary.
Tips
Print the ASCII binary chart. Looking up each letter is part of the experience.
Start with just the first initial to test the concept before committing to a full name.
8 beads per letter (8 bits = 1 byte) is the standard. This is a great way to introduce the term "byte."
Try decoding a friend's bracelet without being told the name. Real cryptography!
For advanced kids, discuss why computers use binary (on/off electrical signals) rather than our decimal system.
