Lab Tour

I know I like to tour other people’s labs, so I guess it’s only fair I presented mine. It’s nothing fancy and far less well equipped than some of the wonderful man caves people show on Dave Jones’ EEVBlog, but it gets the job done and I’m pretty happy with the setup as it is right now.

Weller WTHA 1

I have been in the market for a hot air station for some time now. A bit of research quickly showed that many people recommend JBC stations. Sadly their price point is a bit above what I consider acceptable for my hobbyist use case, and since I am very happy with my Weller 81 soldering station I decided to go for the Weller WHA 900.

While browsing for it I saw that Weller had just announced a new line: the WTHA 1! A quick spec check later, I decided that I did not need the WHA 900’s foot switch and that the new unit had a much sexier design than the 900. I was sold, so I quickly placed my order…

Rohde & Schwarz HO3508 Logic Probe

I’ve been poking around digital circuits with my oscilloscope’s analog probes for over 2 years now and basically it works just fine.

But. (And this is a big but.)

As soon as you need to have a look at more than one or two signal lines (say you’d like to look at a bus) this setup gets messy real quick. The analog probes are big, long and unwieldy; and due to their weight they tend to shift your PCB around as soon as you look at them the wrong way. Not very ergonomic. On top of that my scope only has 4 analog inputs, making debugging of more complex digital circuits impossible.

But that’s not the only problem with analog probes.
