Finally made the HPM in strip board an instructables. Hopefully it will grow and develop as people engage with it!
Using transfer paper and then etching process I was able to create this circuit board. Needs to be drilled out and then all electronics can be soldered on!
This is the second strip board module that I have built. It changes the orientation of the arduino and sensor and places them vertically while facing the potentiometers outward, creating a ‘T’ layout. Hopefully leading to a tidier and more compact housing. Again the power source is external to the circuit and not included as size and the appropriate battery holder were still being sought after (now found!).
This is my first attempt at a single pcb module. All elements except for the battery have been soldered to the strip board. This allowed for two things, shrinking and tidying the module while teaching me about circuit layouts and considering layout to suit size.
Images of the first module build, from CAD render to 3D printed housing to wiring assembly. The final outcome is an unsuccessful module. It will require disassembly and reassembly outside of the housing to debug and diagnose any problems. Stay tuned…
