That sort of frequency counter would probably be fine. I think it shows to 10 Hz if the frequency is low enough. Frequency counting isn't difficult so a specialised unit that only reads frequency isn't expensive. However, frequency counting needs the sort of dedicated circuitry which isn't in all oscilloscopes.Wonderful feedback, everyone! I am thrilled that I have found this forum!
The comments about frequency counters vs. oscilloscopes are well-taken. I am completely inexperienced in purchasing frequency counters, however. I see, for example, this inexpensive unit that covers the frequency range I need while reporting what seems to be down to the 100 Hz position. Is that the kind of thing I am looking for? I see other instruments that go up to several hundred dollars. I have the money to make a purchase of a good instrument if it is necessary, but the general applicability of this approach will increase the cheaper the components I can get away with are.
An excellent point, it upsets my sensibilities also.How about adding a supply decoupling capacitor across it, and see if that makes any difference - it's absence is upsetting my sensibilities!
More or less.So am I interpreting your mock-up correctly as follows:
In this circuit, the transistor is not critical.you used a different transistor than the one that I started the thread asking about. How much does the specific transistor matter?
Look here:what transformer should I be looking for to make this work, if I am looking to purchase
Yes.So it seems to get higher frequencies, I may need a lower-inductance transformer. Is that right?
Putting two inductors in parallel will lower the inductance.And if so, are there tricks you can play with multiple transformers to adjust the inductance the same way you can play with resistors and capacitors in parallel or series?
it's only good if you know why the oscillator started working, or if the futzing helps you understand the circuit better.Futzing is good, especially when I leads to working oscillators.
