I have been attempting to build the "Dancing LEDs" circuit for my grandson using a
breadboard as a 'testing location' prior to building it in a permanent closure.
The circuit can be found on this site at:http://www.electronic-circuits-diagrams ... kt10.shtml
I have yet to be able to get it to work. As information I substituted 2N4401 transistors for the
BC548 type since the characteristics are pretty much the same. Both are NPN types with specs
that are similar enough to be interchanged for the project. All other components used were
as specified in the circuit. I have disassembled and rebuilt it several times being very careful
to wire it exactly as it is shown, but have had no success in getting it to operate.
So, my question is: Has anyone else successfully built this project and if so, did you find
any errors in the circuit schematic?
Thanks in advance for any help.
