We are the Electrons. We learned that '+ and -' came together, in a dance we showed this with shaking our body but when '- and -' came together they would clash. How the Electrons react is explained further in the drawing that we made, on the left.

–––––––––––––––––––––––––––––––––––––––––––––––––––––––––––––––––––––––––––––––––––––––––––––––––––––––––––––––––––––––––––––––––––––––––––––––––––––––––––––––––––––––– In this class we started with a summary of the first class. In a battery the elektrons go from the + side to the - side. A Led light has a long and a short, the long side is the + side and is called Anode, the short side is the - side and is called Cathode. A resistor is to limit the presure of the battery for a Led light for example. A resistor = Ohm. You can calculate how much the resistor resists with a dutch"donkey bridge": Zij bracht rozen op gerrits graf bij vies grauw weer
1-2-X-------
Zij = Zwart = 0-0-1
Bracht = Bruin = 1-1-10
Rozen = Rood = 2-2-100
Op = Oranje = 3-3-1000
Gerrits = Geel = 4-4-10K
Graf = Groen = 5-5-100K
Bij = Blauw = 6-6-1M
Vies = Violet = 7-7-10M
Grauw = Grijs = 8-8-100M
Weer = Wit = 9-9-1000M

Further in this class we did some small experiments in a group. We made a circuit on a plugboard with a 9 volt battery, a resistor and a LED. the rest of the experiments were about measuring with a volt meter.
What you need (ask at the Interaction Station):
* Multimeter * 9 Volt battery (5V in the tutorial) * 9 Volt battery clip for in a breadboard * 470 Ohm resistor (1K Ohm in the tutorial) * LED * breadboard
Outcome: Voltage 7

In the third class we had to make a Keyboard. in this assignment we could show what we have learned about circuits with resistors and LEDs, and about measuring voltage. we also learned new things about how to adjust a copper plate, and how to solder a microchip. First we picked a schematic. Axel Verwee and I had schematic 1 so we teamed up for this assignment. We had to draw the circuit on a copper plate. Ad first we tried to iron a printed image on the copper. if the ink would have sticked on the copper we could have put the copper in a gemecal bath but this only worked for half of the image. Then we grinded our version of the schematic on the copper plate. The soldering of the chip was the hardest part, this went wrong the first time as the paws of the chip broke when we tried to attach the treads to other componends and on the copper plate. The second time we first connected all the paws of the chip to other threads. then we soldered all the other componends on the copper plate, and at last we connected te threads from the chip to other parts on the plate untill everything was connected. We designed our keyboard in such a way that the chip was floating in the air. It was very nice to look at and it worked! you only had to hold the speaker up because we placed it upside down; the metal part under the speaker made contact to the copper plate which we could solve with a small piece of tape underneed the speaker.
