We’re digging these photos by Nava Whiteford showing the guts of a 1980s/90s-era electrophysiology instrument. It’s always fun peering inside these old boxes, to see what you can identify, from hex inverters to non latching relays, or that polypropylene high-frequency capacitor. What else can you spot that’s interesting?
I picked up an Axon instruments Axopatch 200A on ebay (it’s a patch clamp which can be used for ion channel experiments among other things). Here are some PCB pics for your viewing pleasure.
