The other day, while cleaning out the garage, I found my old Arduino Uno. A few years ago, I received this as a new year's present by my employer at that time. Back then, I thought I was going to do something usefull with it. But apparently I didn't, since it was gathering dust on a shelf in the garage. I also did not recall the fact there was an ethernet hat available in the package. So it has an ethernet hat, what can we do with it?

After swapping the halogen lights in a different fixture, it was confirmed the transformer was dead. I searched the web and Osram still manufactures these electronic transformers, but now they have very different dimensions. The fixture only allows the transformer to be 1cm tall, not taller. After a long search I found this one , from a different manufacturer. The transformer had the same formfactor, more or less, but the power output has a maximum of 105W, whereas the Osram has a maximum of 120W. Lukily the halogen lamps are only 100W, so the new transformer should work, without setting anything on fire :D Replacing the broken transformer did the trick and all lights were working again. I did not throw away the Osram transformer yet, hoping I could fix it somewhere in t
