I told them I was ill

[artag]

So, I get a big pile of interesting new (to me) test equipment to play with. I briefly test several of them, but I don't investigate them more deeply or try out all the exciting features.

I look up the service manual and take apart the one that doesn't work.

Am I sick ?

[Kjelt]

nah you got too much interesting stuff at once, they call it burnout 
You are on the right track, just pick the most interesting one and start with that, saving the rest for later. One at a time, slowly, and stop when you are no longer enjoying it.

I would have taken apart the ones that DO work, and see why they were not broken!
