Day 2 - Ohms Law

Day 2 and today most of the students had to join an exam and it was obvious which activity they prefer to attend...so only with a group of 4 we were able to scale up the welding table we tested successfully yesterday.

With a good help of the faculties workshop and some tools from Marcels Workshop we were able to build the actual size welding table very fast and we found ourself drilling 0.3 mm holes and tying down the heat wire with even thinner wires ...crazy enough to deal with such small parts to build
meter sized inflatable cushions ...

Honestly after such a great start yesterday we thought we would not encounter any problems today, but at the end of the day we were able to experience ohms law in practice: The longer the heat wire
the more voltage you need and the lower the amperage will be ...after a long day of experimenting its sound so easy but how do we get the needed 60 V if we only have power supplies that deliver max 30 V ...

Lets see. Now that the knowledge is discovered we will also fix this problem ...
