For the Maker Faire in Groningen (the Netherlands), I was so lucky to host a workshop, making stuff with visitors.

So the question popped up: what would visitors like to make during a Maker Faire? Well, creatures of course!

So I wanted to make a no-soldering, low cost,  one-hour version of Blinky the Led Pet. Of course, it turned out totally different. It became a Blinky Dragonfly... The dragonfly's electronic brain is the same as Blinky's, but it's structure and looks are really different. This Instructable is for everyone who didn't have a chance at the Maker Faire Groningen to make a Blinky Dragonfly.

The Blinky Dragonfly was a huge success at the Maker Faire! In five hours, the stack of parts (generously sponsored by electronics shop Okaphone) was completely drained and 30 creatures were made by visitors. Have a look at the pictures for an impression of what was made.

This Instructable is an entry in Kiteman's International Go Pro Contest, a solace for the thousands of Makers who can't enter their work in contests anymore, since Instructables (read: Autodesk) is not willing and able to accept international entries.
If you like this Instructable, please try to bribe Kiteman into letting me win a prize :-)

In the upcoming steps are a how-to make your own Blinky Dragonfly. Total costs are around €3,- (US$ 4) and it will take one to two hours to make, depending on your makers experience. 8 to 14 year olds might need some assistance of a grown-up. Have fun, and please post a picture in the comments if you made one.

Step 1: Parts and Tools

Parts you need:
Euros, for a one-stop shop visit Okaphone (NL, B, D, GB), Conrad or Farnell. The rest of the world, try Radio Shack or Farnell
  • Electric wire Connectors! At least 24 stubs (two rows of 12), but more is better...
  • Solid kern electrical wire, 1,5 mm2 or 2,5 mm2 (the wires that are used connecting the wall-plugs in your house)
  • 2 10mm LEDs, any color you like
  • 2 transistors BC547(B)
  • 1 Resistor 100kOhm
  • 1 9 Volt battery (Carbon-zinc batteries are fine for this project, and very cheap!)
  • A battery-clip
  • Tie raps, any color you like
  • Jumper wire / thin, solid kern wire

  • Pliers to cut and bend the electric wire
  • Small screwdriver for the connectors
  • Sharp knife, to cut loose connectors
  • If you like, pliers to remove the insulation from the wires
<p>I have little experience with electronics, so I could not figure out which LED to use. Which voltage LED should be used?</p>
Anything works, actually. Cheapest are the red 10mm leds that I used in the project. Like these: https://www.conrad.nl/nl/kingbright-l-813src-c-led-bedraad-rood-rond-10-mm-1500-mcd-40-20-ma-185-v-180234.html
could i use a c1815 transistor please reply <br>
<p>Any general purpose NPN would do, so yes. This one, 2N2222, etc.</p>
Cute! It's great that you can make something like this in an hour. This would make a nice kit to sell.
Thanks! I'm about to make a kit out of it, since this was such a success.
