The ATtiny85 chip is a simple $2 way to get into Arduino.

It's the basis of low-cost microcontrollers like the Digispark, the Picoduino, the Trinket, and for e-textiles, the Gemma, and the LilyTiny.

These off-the-shelf boards are brilliantly designed and great for one-offs. If, however, you need a bunch (or you're feeling crafty), you can make your own wearable board.

Materials:

Stripboard (aka veroboard)

Solder

Chip - ATTiny85. Learn more about it here.

Chip socket - 8 pin

Tools:

Dremel with cutting wheel (or a box cutter)

Clamps

Soldering workstation (soldering iron, safety goggles, fume extractor, tip cleaner, etc.)

Programming shield for ATTiny85

Chip extractor tool

Step 1: Cut the Stripboard

Clamp the board so you can cut it.

Using the dremel, cut the board to size: for an 8 pin chip, I cut a board 4 rows x 10 holes.

  1. Draw a line with a marker on the plastic side, along a row of holes.
  2. Use the dremel to cut away most of the plastic on the line.
  3. Snap the board at the score.

(Don't breathe the dust!)

Next, on the copper side, lightly cut a groove down the middle through the copper layer only so your 4 rows are now 2 columns.

Use a multimeter to make sure the left columns are completely separate from the right.

Note: You could do this with a boxer cutter instead of a dremel. Score the board by running the box cutter along a ruler clamped in place. Snap it along the score. Cutting this way is less accurate so make the board larger to compensate. The box cutter will also work on the copper traces.

great...i am reading about bootloader...and still iam not confidant
<p>Sometimes it's harder to read about these things than to actually do them. Don't give up-- I bet you'll figure it out!</p>
<p>This is so cool!</p>
<p>Thank you!</p><p>:-)</p>
<p>Awesome! This is just such a great idea! =D</p>
<p>Thanks! I hope you find it useful!</p>
