  • This is an excellent kit and alot of fun to build. I coupled this with a BNC jack and the frequency counter kit and now have a pretty handy trouble shooting tool. Need some sort of armored case enclosure for it though…

  • What is the diameter of this knob at the flare? I am looking for something to use on the function generator kit’s potentiometers shafts.

  • Is there a step down module available for these batteries for use with 3.3 VDC applications? Or are these close enough in voltage for it not to matter?

No public wish lists :(
