This is an update on my "Let's make a Low Power Oscillator" project. Previously I copied Lidmotor's "Penny" blocking oscillator circuit using the pound shop twist tie coils and was pleased with my success. Then I noticed that slider2732 had modified the circuit using a suggestion from iluzyon1 to use axial inductors in place of the coils. Having just scavenged some of these axial inductors from a circuit board I realised I could quickly do the same modification and within a few minutes I had the new version up and running. I have included a few still photos of my breadboard circuit with the axial inductors added where there was a convenient space and jumpered into the circuit using orange wire. The inductors simply replace the original coils in the original circuit diagram.
