Inside a 30-Year-Old Patch Clamp Instrument by Axon
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.
Stop breadboarding and soldering – start making immediately! Adafruit’s Circuit Playground is jam-packed with LEDs, sensors, buttons, alligator clip pads and more. Build projects with Circuit Playground in a few minutes with the drag-and-drop MakeCode programming site, learn computer science using the CS Discoveries class on code.org, jump into CircuitPython to learn Python and hardware together, TinyGO, or even use the Arduino IDE. Circuit Playground Express is the newest and best Circuit Playground board, with support for CircuitPython, MakeCode, and Arduino. It has a powerful processor, 10 NeoPixels, mini speaker, InfraRed receive and transmit, two buttons, a switch, 14 alligator clip pads, and lots of sensors: capacitive touch, IR proximity, temperature, light, motion and sound. A whole wide world of electronics and coding is waiting for you, and it fits in the palm of your hand.
Have an amazing project to share? The Electronics Show and Tell is every Wednesday at 7pm ET! To join, head over to YouTube and check out the show’s live chat – we’ll post the link there.
