A special edition christmas arduino workshop. We'll be using a new very small arduino clone called ["Trinket"].
We can make a christmas star/tree with sound effects.
Ardillo did some research and collected a list of parts which can be bought for a fair price.

Christmas kit

The Trinket is one of the cheapest clone (unless you tinker around yourself).
We've made a DIY christmas kit which consists of the following:

Parts 0xchristmas

amount what price url
1 trinket 5V Logic €8,00 [floris.cc-trinket]
1 breadboard €4,00 [floris.cc-breadboard]
1 USB - mini USB cable €2,08 [Farnell-usb cable]
1 Piezo buzzer €1,00 [Farnell-piezo buzzer]
1 Light Dependant Resistor €0,77 [Farnell-LDR]
2 high power LED's €0,60 [Farnell-LED's]
 ? red/green LED's €?? Randomdata's own supply
 ? jumpers/cables/wire €?? Randomdata's own supply
1 splitted shipping costs €0,56 Farnell & Floris.cc shipping divided by amount of kits
Total €17,01 aproximitly €20

The url's of Farnell are without tax, our price is with 21% tax.

trinket HowTo

During the workshop we tell about arduino's and why they are awesome.
The Trinket is a little different but still easy to work with. It is important to know that your trinket is a 5V Logic version (not the 3.3V). This important when connecting your trinket to sensors, they have to be of the same voltage as your trinket.
Adafruit made a good tutorial on how to use this trinket.

0xchristmas workshop

So for making a Christmas tree/star with sound effects we made a guidance workshop where you are doing all the work and we are just helping.
For connecting everything together we need some jumper wires, there are a couple of ready-to-use cables available or you can make your own from some scrap electronics, especially solid core network cable works fine.

...more to come, still work in progress...

Just an ordinary cable nothing more to say. One side has a USB connection for your laptop and the other side has te be connected on your trinket.
