Pete sets out to make some current probes for his scope / multimeter. This part shows the prototype design of the hall-effect probes along with breadboard build and thinking forward to the actual build. Stay tuned for part 2 in which he converts it to a pcb that his supplier can assemble and also designs and orders orders the probe clamp plastic shells. He is concerned he may not have good enough thermal control but only time will tell!
Part 2 now available • Designing a Current Cl...
